Authors: Khder Mustafa Saifadin , Zrar Omar Shaaban , Kamal Ahmad Kewan , Basil Khudhur Lana
Published: February 2023

Introduction: SARS-COV-2, the novel severe acute respiratory syndrome coronavirus, has become a life-threatening public health crisis. This kind of pandemic is frightening the world with clinical, psychological, and emotional distress and leading to an economic slowdown. To explore any association between the ABO blood type and the susceptibility to coronavirus disease 2019 (COVID-19), we compared ABO blood group distribution among 671 COVID-19 patients with the local control population.
Methodology: The study was conducted in Blood Bank Hospital in Erbil, Kurdistan Region, Iraq. The ABO-typed blood samples were obtained from 671 patients infected with SARS-CoV-2 between February and June 2021.
Results: Our results demonstrated that the risk of SARS-COV-2 was higher for patients with blood group A than those with not-A blood type patients. Of the 671 patients with COVID-19, 301 had type A (44.86%), 232 had type B (34.58%), 53 had type AB blood (7.9%), and 85 had type O (12.67%).
Conclusions: We concluded that the Rh-negative blood type has a protective effect on SARS-COV-2. Our results also indicate that the decreased susceptibility of individuals with blood group O and the increased susceptibility of individuals with blood group A to COVID-19 could be linked to the presence of natural anti-blood group antibodies, particularly anti-A antibody, in the blood. However, there might be other mechanisms that require further study.
Using drone imagery to obtain population data of colony-nesting seabirds to support Canada’s transition to the global Key Biodiversity Areas program

Published: February 2023

Identifying of global or national biodiversity ‘hotspots’ has proven important for focusing and prioritizing conservation efforts worldwide. Canada has nearly 600 Important Bird and Biodiversity Areas (IBAs) identified by quantitative criteria to help guide avian conservation and management. Marine IBAs capture critical waterbird habitats such as nesting colonies, foraging sites, and staging areas. However, due to their remote locations, many lack recent population counts. Canada has begun transitioning IBAs into the global Key Biodiversity Areas (KBA) program; KBAs identify areas that are important for the persistence of biodiversity and encompass a wider scope of unique, rare, or vulnerable taxa. Assessing whether IBAs qualify as KBAs requires current data – as will future efforts to manage these biologically important sites. We conducted a pilot study in the Chain Islets and Great Chain Island IBA, in British Columbia, to assess the effectiveness of using drones to census surface-nesting seabirds in an IBA context. This IBA was originally designated for supporting a globally significant breeding colony of Glaucous-winged Gulls (Larus glaucescens). Total nest counts derived from orthomosaic imagery (1012 nesting pairs) show that this site now falls below the Global and National IBA designation criterion threshold, a finding consistent with regional declines in the species. Our trial successfully demonstrates a flexible and low cost approach to obtaining population data at an ecologically sensitive KBA site. We explore how drones will be a useful tool to assess and monitor species and habitats within remote, data-deficient IBAs, particularly during the transition to KBAs.

The End of Days Deferred: Imperative Agency, Collective Responsibility, and Corporate Communication
Authors: Price Stuart
Published: February 2023

This article analyses the discursive configuration of a widespread assumption – that the event of climate emergency should be met with some form of concerted collective action. Beginning with references to the concept of 'greenwashing', it goes on to note the temporal framing
of climate disaster and the imperative agency advocated in the types of address used by news organisations, climate scientists and bodies (like the United Nations) devoted to global governance. Standard media practices, which serve a vital function in circulating meaning, are also discussed,
on the basis that, while they seem to advocate timely intervention, they also disassociate environmental awareness from the radical measures needed to mitigate disaster, displaying an ambiguous or (in some cases) hostile attitude to the activist forces that could drive recuperative
transformations in climate policy.
 I argue that effective mitigation is deferred for three interrelated reasons: first, because of the recurrent emphasis placed on momentous (future) tipping points, which obscures a more insidious and rapid deterioration in the present; second,
the preeminent tendency of mediated climate discourse to call for 'leadership' on issues that a deeply compromised political establishment cannot fully address; and third, state/corporate collusion, which makes a show of balancing competing demands (economic growth and zero emissions, for
example), but is actually committed to a criminal model of industrial enterprise. Taken together, these factors – combined with the neglect of subaltern and alternative voices and the instinctive journalistic deference shown to elite social actors and their 'authoritative' utterances
– help replicate the material/ideological structures of the social order and its hierarchical distinction between, on the one hand, leadership figures and, on the other, an infantilised public supposedly in need of rational direction.
 The article substantiates these observations
by analysing the PR strategies of the oil and gas company, bp, while distinguishing between greenwashing critiques and the approach advocated here, which recommends the delegitimisation of corporate discourse on the basis that corporations have no right to engage in what is in effect a form
of political communication. The conclusion to this piece suggests that, if the span of human life on earth has indeed been circumscribed by climate breakdown, then the emergency is political, and fighting for an immediate and 'immoderate' form of social justice is the only way to address a
crisis that elite social actors seem determined to ignore, misrepresent or monetise.
Scale Critique for the Anthropocene, Part Two
Authors: Woods Derek
Published: February 2023

Scale critique applies to time as well as space. Thinking with temporal scale variance can help us avoid seeing deep time as sublime, numerical, and continuous. By reading Stephen Jay Gould with Michael Madsen's documentary Into Eternity, this essay argues that the second concept
of scale critique is about the fit, good or bad, between a temporal scale domain and a narrative timeframe. Because temporal scale domains have material finitude and specificity, they counteract the timelessness that accrues to ideologies of extinction.
Enhanced stress resistance of Bifidobacterium breve NRBB57 by induction of stress proteins at near-zero growth rates

Published: February 2023

Bifidobacterium breve is a common habitant of the human gut and is used as probiotic in functional foods. B. breve has to cope with multiple stress conditions encountered during processing and passage through the human gut, including high temperature, low pH and exposure to oxygen. Additionally, during industrial processing and in the gut, B. breve could encounter nutrient limitation resulting in reduced growth rates that can trigger adaptive stress responses. For this reason, it is important to develop culture methods that elicit resistance to multiple stresses (robustness) encountered by the bacteria. To investigate the impact of caloric restriction on robustness of the probiotic B. breve NRBB57, this strain was grown in lactose-limited chemostat cultures and in retentostat for 21 days, at growth rates ranging from 0.4 h-1 to 0.00081 h-1. Proteomes of cells harvested at different growth rates were correlated to acid, hydrogen peroxide and heat stress survival capacity. Comparative proteome analysis showed that retentostat-grown cells had significantly increased abundance of a variety of stress proteins involved in protein quality maintenance and DNA repair (DnaJ, Hsp90, FtsH, ClpB, ClpP1, ClpC, GroES, RuvB, RecA), as well as proteins involved in oxidative stress defence (peroxiredoxin, ferredoxin, thioredoxin peroxidase, glutaredoxin and thioredoxin reductase). Exposure to three different stress conditions, 45 °C, pH 3, and 10 mM H2O2, showed highest stress resistance of retentostat cells sampled at week 2 and week 3 grown at 0.0018 and 0.00081 h-1. Our findings show that cultivation at near-zero growth rates induces higher abundance of stress defence proteins contributing to the robustness of B. breve NRBB57, thereby offering an approach that may support its production and functionality.

Published: February 2023

Previous studies using ileostomy samples from study participants demonstrated that the spore-forming probiotic Bacillus subtilis DE111® can germinate in the small intestine as early as 4 hours after ingestion. Metabolomics, proteomics and sequencing technologies, enabled further analysis of these samples for the presence of hypoglycaemic, hypolipidemic, antioxidant, anti-inflammatory and antihypertensive molecules. In the DE111 treatment group, the polyphenols trigonelline and 2,5-dihydroxybenzoic acid, orotic acid, the non-essential amino acid cystine and the lipokine 12,13-diHome were increased. DE111 also reduced acetylcholine levels in the ileostomy samples, and increased the expression of leucocyte recruiting proteins, antimicrobial peptides and intestinal alkaline phosphatases of the brush border in the small intestine. The combination of B. subtilis DE111 and the diet administered during the study increased the expression of the proteins phosphodiesterase ENPP7, ceramidase ASAH2 and the adipokine Zn-alpha-2-glycoprotein that are involved in fatty acid and lipid metabolism. Acute B. subtilis DE111 ingestion had limited detectable effect on the microbiome, with the main change being its increased presence. These findings support previous data suggesting a beneficial role of DE111 in digestion, metabolism, and immune health that appears to begin within hours of consumption.

Published: February 2023

Gut health is multifaceted and is largely influenced by the rearing environment and the diet. The use of phytochemicals rich in phenolics and flavonoids can improve the digestive health of chickens and lead to better growth performance. The aim of this study was to examine the effects of dietary Vernonia amygdalina leaf meal (VALM) on growth performance, digestive enzyme activities, absorption function, organ weights and immunity of broilers. Two hundred and forty, one-day-old male Cobb 500 broiler chicks were randomly divided into four groups: an unsupplemented control and VA-1, VA-3 and VA-5 receiving VALM incorporation at concentrations of 1, 3 and 5 g/kg, respectively. Each treatment had six replicates of 10 chickens. On d 42, six chickens per replicate were isolated and euthanised. Digesta from the jejunal segments (10 cm) was collected for analysis of the digestive enzymes. The remaining digesta was then washed out with ice-cold phosphate-buffered saline before the jejunal segments (10 cm) were opened longitudinally to collect the mucosa by scraping. For the preparation of the homogenate, intestinal mucosa samples were homogenised with 154 mmol/l of ice-cold sodium chloride solution and centrifuged at 4 °C for 900 s. To determine immunoglobulins, glutathione and D-xylose, the supernatant was extracted and stored at -20 °C. Supplementation with VALM did not significantly influence the relative weights of organs in the different treatments. However, VALM at 3 g/kg caused a significant increase in amylase and trypsin concentration (P<0.05). Immunoglobulin A and intestinal secretory immunoglobulin G concentrations were significantly improved (P<0.05) in the birds fed 3 g/kg VALM. This supported the premise that 3 g/kg VALM in feed can improve gastric immunity status and digestive enzyme secretion.

To evaluate the effects of the inclusion of three insect meals in dogs’ diets (Madagascar cockroach, MC; cinerea cockroach, CC; and superworm, SW) at two different levels (7.5 and 15%) on nutrients digestibility, blood parameters, faecal characteristics, volatile fatty acids, and gut microbiota, a digestibility trial was performed in a 3×2 factorial scheme in Latin square design 6×6. Experimental diets consisted of insect meals replacing the reference diet (dry and moist commercial feeds) on each of the two levels. Apparent metabolised energy of dry matter (AMEDM) was higher for dogs fed with SW than MC meal in both inclusion levels and, with CC meal at 7.5% of inclusion. The digestibility for dry and organic matter and protein was higher for dogs fed with SW than for MC meals. The faecal pH was lower for the dogs fed with CC than for the MC meal. Butyrate was higher for dogs fed with CC than MC and SW meals. Phenol was higher for dogs fed with MC than SW meal. The relative abundance of the phyla Proteobacteria and the genusSutterella were higher at 7.5% of inclusion than 15%. Dogs fed with SW meal had a greater abundance ofPrevotella,Faecalibacterium, and an unidentified genus in the family Ruminococcaceae than dogs fed with MC meal. The abundance ofAllobaculum was higher for dogs fed with SW meal than CC meal. Even though all the insect meals evaluated can be included in adult dogs’ diets, the superworm meal appears as a highly digestible ingredient for dogs with lower negative impacts on intestine fermentative products and microbiota profile.
Psychotherapy in Bipolar Depression: Effective Yet Underused
Authors: Chiang Karl S. , Miklowitz David J.
Published: February 2023

Psychotherapy is an important part of managing bipolar depression and its associated impairments. There is considerable evidence that psychotherapies are effective adjuncts to pharmacotherapy in delaying or preventing episodes of bipolar depression. Individuals with bipolar depression may be reticent to consider these treatments. This paper surveys the utility, evidence base, effective treatment components, and controversies surrounding adjunctive psychosocial interventions.

Antidepressants in Bipolar Depression: Still Controversial After All These Years
Authors: Mansur Rodrigo B.
Published: February 2023

The use of antidepressants in the treatment of bipolar disorder (BD) has been one of the more enduring controversies in the field. Antidepressants continue to be one of the most widely used classes of psychotropic agents in BD and are still prominently featured in most treatment guidelines, despite the limited and inconsistent evidence supporting their safety and efficacy in the treatment and prevention of episodes of bipolar 1 depression. Herein, the authors review the clinical and meta-analytical evidence on the efficacy and safety of antidepressants in BD types 1 and 2. Clinicians should be aware of the potential risks and benefits of anti-depressants for patients with BD, as well as the scenarios and patients' characteristics that can affect treatment outcomes.

Stimulants in Bipolar Depression: Risks and Benefits
Authors: Nuñez Nicolas A , Salgado Manuel Fuentes , Frye Mark A.
Published: February 2023

While mania is the illness hallmark, the depressive phase of bipolar disorder is the main driver of treatment resistance, functional disability, and suicidality. The 5 FDA approved anti-psychotic treatments for bipolar depression represent an important milestone for a clinical evidence base, but new ways of framing and rethinking care management for the depressive phase in bipolar disorder are needed. This article reviews the controversy surrounding the use of stimulants for bipolar depression. We summarize approved recommendations, discuss mechanisms of action, and compare risks and benefits to provide a new perspective and direction as how to individualize care and consider novel treatment strategies for patients with bipolar depression.

A Derivative Hilbert operator acting from Bergman spaces to Hardy spaces
Authors: Xu Yun , Ye Shanli
Published: February 2023

Let $ \mu $ be a positive Borel measure on the interval $ [0, 1) $. The Hankel matrix $ \mathcal{H}_{\mu} = (\mu_{n, k})_{n, k\geq 0} $ with entries $ \mu_{n, k} = \mu_{n+k} $, where $ \mu_{n} = \int_{[0, 1)}t^nd\mu(t) $, formally induces the operator as follows:

   \begin{document}$ \mathcal{DH}_\mu(f)(z) = \sum\limits_{n = 0}^\infty\left(\sum\limits_{k = 0}^\infty \mu_{n,k}a_k\right)(n+1)z^n , \; z\in \mathbb{D}, $\end{document}

where $ f(z) = \sum_{n = 0}^\infty a_nz^n $ is an analytic function in $ \mathbb{D} $. In this article, we characterize those positive Borel measures on $ [0, 1) $ such that $ \mathcal{DH}_\mu $ is bounded (resp., compact) from Bergman spaces $ \mathcal{A}^p $ into Hardy spaces $ H^q $, where $ 0 < p, q < \infty $.

Published: February 2023

Background

Obesity is a complex and multifactorial disease marker, which has become a major threat to cardiovascular health. We sought to assess the correlation of obesity and other cardio-metabolic risk factors in patients seen at the outpatient specialist clinic in Ghana.

Methods

A prospective cross-sectional study was conducted on 395 patients at Precise Specialist Clinic in Kumasi, Ghana. A standardized questionnaire was used to obtain demographic, anthropometric and clinical data of patients. Fisher's exact test for statistical significance at a 95% confidence interval was used to evaluate associations between categorical variables. The associations between obesity indices and cardiovascular disease risk factors were analyzed by Pearson's correlation.

Results

Of the 395 participants, 187 were males and 208 were females. The mean (± standard deviation) age of study participants was 59.29 (± 13.93); more than half of the participants were between 50 and 69 years. The mean BMI of male participants was significantly lower than the mean BMI of female participants (28.18 kg/m2 vs 31.16 kg/m2, P-value < 0.0001). Gender was significantly associated with the weight categories (P = 0.0144). Obesity was seen more in females (49.0%) than in males (35.8%). The Pearson correlation analysis also showed a significant positive correlation between obesity, increasing systolic blood pressure (r = 0.1568, P-value = 0.0018) and increasing diastolic blood pressure (r = 0.2570, P-value < 0.0001).

Conclusions

Obesity was found to be significantly associated with female gender, increasing age, increasing systolic blood pressure, and increasing diastolic blood pressure. Efforts to step-up preventive measures to reduce the increasing prevalence of obesity in Ghana are highly recommended.

The aim of the paper is to provide an overview of the results of contemporary research and practices linked to foster care placement matching and the preparation of foster parents and children for their placement world-wide, with special reference to the existing practice in the Republic of Croatia. The success of foster care outcomes is closely related to and depends on, among other things, the quality of the conducted assessment and selection of the most appropriate form of alternative placement concerning the child’s needs, quality of preparatory process and matching, i.e. adjustment of the characteristics of the child and potential foster parents. Matching is a complex process that comprises a series of actions and making a number of decisions which are influenced by various organisational and external factors, as well as those related to the characteristics of an individual case and to the decision-makers. All these factors are described and explained in the paper. Furthermore, the paper emphasises the importance of the timely preparation of the child and the foster family for the arrival of the child for whom it was determined on the basis of the matching process that the placement in that family is in their best interest, but also of the preparation of the parents and family of the child for the experience of removal of the child and entrusting the child to another family. There is no defined model of the foster care placement matching process in the Republic of Croatia. Therefore the author intends to draw attention to it and to arouse scientific and professional interest in this topic in the Republic of Croatia. Key words: alternative childcare; foster care; foster care placement matching; process of preparing for placement

According to the object relations theory, romantic partners are chosen on the basis of similar, complementary emotional needs and that creates a promise on the conscious and unconscious level that all that was missing in the previous relationships of an individual would be repaired through this relationship. However, in any longer relationship the breach of expectations is inevitable (destruction of an idealized image of the partner), which leads to disappointment. The destiny of the relationship depends on the way in which partners will deal with the frustrating knowledge that their idealisations will not be realised, or the level of maturity of the relationship and each partner, which is a test that many do not pass. It is commonly known that divorce rates are higher than ever before, and some divorces become high-conflict relationships in which all emotions caused by the breakdown of the relationship swirl into one common aspect – parental functioning. This paper is focused on the couples who experience a difficult breakdown of their relationship – with a lot of anger, hostility, distrust, and sometimes with the incidents of verbal and/or physical abuse, accompanied by lengthy and distressing court proceedings. It is noticeable that the conflict has a role of redefining the dynamics of their new partnership relation, and at the same time it serves as a defense of a person who does not have to deal with and face with complex unpleasant emotions that are a part of every divorce. Unable to accept, analyse and tolerate the unpleasantness of the emotions brought by divorce, these couples often use defense mechanisms of splitting and projections. The usage of these mechanisms leads to the dynamics which is characterised by a cycle of harassment, retaliation and failed reparation attempts that in turn lead to further splitting and projection, often with the resulting outcome of a high-conflict divorce. Couples remain connected and locked in mutual patterns of conflict interactions, in a kind of a tango of loving hate in a manner which restricts their capacity to separate on emotional and daily practical level. After presenting two cases from practice that describe the outlined psychodynamic terms and the interactions of partners differently, practical implications which are possible in direct work with former partners will be presented.

ABSTRACT The aim of the research was to examine the moderating role of the group status (minority or majority) on the relationship between intergroup contact and willingness to get involved in a collective action with the aim of reducing inequalities of the persons with homosexual orientation with regard to the heterosexual majority. Additionally, the aim was to analyse the moderating role of the group status on the relationship between intergroup contact and perceived intergroup threat. The research was conducted via online survey on a sample of 286 respondents out of whom there were 187 heterosexual persons and 99 members of the LGBTIQ population. The respondents completed a survey which included a measure of quality of contact with the members of the other group, the scale of perceived symbolic threat and the scale of willingness to take collective action aimed at the improvement of the position of the LGBTIQ population. The results show a significant connection between intergroup contact and willingness to take collective action and perceived intergroup threat. The moderating role of the group status was confirmed, whereas on the sample of heterosexual persons a more positive contact with the members of the other group increases willingness to take collective action, while for homosexual persons the intergroup contact is not connected with the willingness to take collective action. Furthermore, the moderating role of the group status was confirmed on the relationship between the quality of contact and perception of symbolic threat, at which a more positive contact with the members of the other group was connected with the reduced perception of that group as a threat in both samples of respondents, but a higher effect of it was observed in the case of heterosexual persons. The results are analysed from the perspective of the contact theory and the neglected role of group status in that context. Key words: intergroup contact; symbolic threat; collective action; sexual orientation

Published: February 2023

The study of cooperative education is important not only for researchers but also for those interested in studying educational methods, such as university professors, teachers in schools, and all educational institutions. This is because of its effectiveness in teaching students, developing their skills, developing their ideas and employing them in the study and finding appropriate solutions to the questions posed by the teacher. It also helps in instilling a spirit of cooperation among the students by dividing them into groups to achieve the desired goals. The aim of the study is to clarify how important it is for teachers to use cooperative education in addressing the educational, social and psychological aspects when teaching students in educational institutions. The study is divided into three sections. The first section presents the general framework of the study dealing with the problem, importance and objectives. The second section deals with the concept of cooperative education, its importance and the date of its inception. This section also discusses the most important theories that I mentioned about its importance, results, foundations and objectives of cooperative education, including its benefits, characteristics, stages and strategies. It clarifies the role of the teacher and student in e-learning. The third topic dealt with the methodology of the research and presentation of the results, their interpretation and discussion. The research reached several conclusions, the most important of which are: the teaching staff in educational institutions enjoy a high level in employing cooperative education in their teaching to students and to achieve the educational, social and economic goals, all of which were significant and used.
Collaborative Grouping and Interactive Relationship Construction of College Students Based on Group Preference
Authors: Chen Fang
Published: February 2023

Collaborative learning allows learners to gain more learning resources, learning experiences, and even learning habits from other group learners, thus improving themselves and achieving better learning outcomes. The existing studies only fully consider the differences in learners' learning preferences, while ignoring the preference of each group and the balance between groups, which is not conducive to the overall improvement of learners' achievements in each group. To this end, this article focuses on studying collaborative grouping and interactive relationship construction of college students based on group preference. A collaborative learning grouping algorithm based on group preference is proposed, considering the differences in learners' learning preferences and the preference of learning groups in a balanced way, and the problems in collaborative grouping of college students are described. A group preference-based collaborative learning grouping algorithm is designed, the main ideas and implementation process of the algorithm are expounded, experiments are designed to compare the intra-group difference degree of different grouping algorithms, and the algorithm’s evaluation method is introduced. The experimental results verify the effectiveness of the proposed algorithm.

Published: February 2023

Interdisciplinary scientific research method plays a significant role in promoting technological innovation. As the principal subject in scientific research activities, college students need to improve their innovation ability using interdisciplinary knowledge resources and knowledge network. Existing researches are mostly carried out from a single perspective of knowledge network, and ignore systematical analysis for interdisciplinary multilayer network. For that reason, the influence mechanism of structural characteristics of interdisciplinary knowledge network on college students’ innovation ability is established in this article. An interdisciplinary-dependent multilayer network is built and network nodes are divided into interdisciplinary knowledge elements, scientific research theme, and discipline and specialty. Structure attribute of interdisciplinary knowledge network and relationship attribute of interdisciplinary knowledge elements are also used to calculate indicators at different knowledge dimensions, and specific indicator measurement modes are proposed. The regression model is built to explore direct influence mechanism of dynamic and static characteristics of interdisciplinary knowledge network on college students’ innovation ability. A regression model is also built to further verify the regulating effect of disciplinary knowledge’s network location attribute of college students’ specialty in influence relationship between interdisciplinary knowledge network and college students’ innovation ability. Last, corresponding analysis result is given based on experiment result.

Authors: Bi Shuyuan , Liu Wei
Published: February 2023

To facilitate front-line teachers to provide more efficient cases for classroom teaching activities in limited teaching time, it is necessary to conduct clustering analysis of online teaching cases. The existing clustering study on text-based teaching resources focuses on the representation and fusion of different views of texts and the discovery of consistent clustering allocation, and ignores the high-dimensional sparsity of text data. To this end, this paper studies clustering analysis of online teaching cases and evaluation of teaching results. This paper gives the design flow of online teaching with case teaching as the core and proposes a text multi-view clustering algorithm based on case subject alignment, and presents a clustering model structure based on subject alignment. Based on the grey system theory, this paper compares online classroom teaching results before and after teachers use clustering algorithm to process teaching cases. Finally, the experimental setup is given, and the effectiveness of the proposed algorithm is verified by experiment.

The present study aimed to develop and evaluate an automated cooling control system (ATCE) for sows in the farrowing phase. The experiment was conducted at the Swine Production Unit, Federal Institute of Education, Science and Technology, Campus Machado, Machado, state of Minas Gerais. Sixteen sows and their offspring were evaluated, eight treated and eight controls, in a randomized block design, with eight replications. Surface temperature, body temperature and respiratory rate of the animals were evaluated, in addition to floor temperature and performance parameters. The use of ATCE decreased the floor temperature (12h) and neck temperature (12 and 16h) (p < 0.10). In addition, there was a reduction in rectal temperature (12h) and respiratory rate (12 and 16h) in ATCE animals (p < 0.10). No significant differences were detected in the coefficient of variation (CV) of birth weight, but at weaning the CV of piglet weight was 26.3% lower in animals subjected to the ATCE (p = 0.079). Furthermore, the difference in CV between birth and weaning was also lower with the use of ATCE (p = 0.015). It can be concluded that the use of ATCE has a positive influence on the thermal comfort of females, in addition to improving litter uniformity.

The objective was to evaluate fertility, cyclicality behavior, and sexual performance of Pantaneiro sheep throughout the year’s photoperiods in Mato Grosso do Sul - Brazil. Two experiments were conducted. In experiment one, the ewes used aged between 2 and 4 years, distributed in three homogeneous groups of 54 animals and subjected to reproductive evaluation in three different predefined luminosity periods, consisting of autumn (11h 45 min.), spring (12h 30 min.), and summer (12h 55 min.). The characteristics studied were body weight (BW), body condition score (BCC), estrus distribution (EST), percentage of pregnant females per cycle (%P), plasma progesterone (PP), and fertility (F) in the three predefined seasons. The mating system used was controlled natural nocturnal and lasted for 45 days. Experiment two, evaluated the ram sexual activity. The males (10) were individually exposed to four ovariectomized ewes. The ewes cycled during evaluated seasons, and the highest fertility was observed in animals with BCC >2.75. The PP concentration differed among periods, and higher conception rates (F) were observed in autumn and spring. The rams (75%) had a medium  of sexual performance when they performed more than two ejaculations in 20 min throughout the seasons. Pantaneiro sheep of both genders had a similar fertility index, with early and constant activity throughout the year, displaying no photoperiodism or seasonality.

There have been determined the features of m. longissimus lumborum steaks from young cattle-for-fattening of Holstein-Friesian breed, Polish black-and-white variety. There were measured pH values, basic chemical composition and colour parameters. The meat was subjected to moist-ageing for 12 days and, next, stored in modified atmosphere for the following 10 days. The amount of heat loss in relation to the temperature of thermal processing was determined. Texture parameters were studied instrumentally and organoleptically. The studied muscles from young cattle-for-fattening characterised with proper and similar pH values. The average fat content was 4.37%. The surface colour of the studied dorsal muscle was relatively bright, the average value L*=37.97, and on the cross-section L*=32.97. The average value of the muscle surface's ‘redness’ was a*=18.98, whereas cross-section's a*=20.27. The amounts of heat leakages were rising along with the increase of temperature from 11.24 to 37.14%. Ageing and storing in MAP led to a significant decrease in the amounts of heat leakages. Ageing and storing in MAP had a significant influence on decreasing shear force and on increasing the organoleptic evaluation marks of the m. longissimus lumborum after thermal processing, which shows that the muscle may become culinary meat with features accepted by consumers.

This study aimed to determine the effect of using different sources of nitrogen to supply part of degradable intake protein needs in lactating goat performance and its effect on excretion of microbial purine derivatives and blood metabolites. Thirty-two lactating Saanen goats (body weight 38.85 ± 2.14 kg and 1979 ± 0.25 g day-1 milk yield) were used in a one-way ANOVA completely randomized design. Goats were assigned to the following treatments for a 10-wk experimental period: 1) Control (canola meal as a nitrogen source); 2) Urea (0.5% urea); 3) Optigen (0.55% Optigen- Alltech. Inc., Lexington, KY) and 4) Polymer-Coated Urea (PCU- international patent number: A01K5/00, 0.7% PCU) based on dry mater intake. Non-protein nitrogen groups had a comparative effect (p > 0.05) between control and other treatments on milk composition, microbial protein synthesis and they affected on blood factors including urea, cholesterol, and ALT. Dry matter intake decreased (p > 0.05) in PCU, Optigen, Urea than Control goats. Synthesis of microbial protein in PCU goats was 22.5 g day-1 and it was greater (p > 0.05) than other treatments. Plasma cholesterol was increased in PCU and Optigen, whereas urea concentration was increased in Urea and Control goats. Milk production was higher in PCU than Urea and Control. Feed conversion ratio was improved (p > 0.05) in PCU and Optigen goats versus other treatments. This study demonstrated that polymer-coated urea can be utilized as a nitrogen source and improve goats milk performance.

The objective of this study was to evaluate the effect of threonine:digestible lysine ratio in the diet on the physiological variables and weight of organs of light laying hens. Two hundred and ten 47 week-old Dekalb White laying hens were distributed in a completely randomized design, with five levels of threonine (0.507; 0.552; 0.597; 0.642 and 0.677%) and seven replicates of six birds each. The experimental period was 10 weeks, totaling 62 days and more eight days for the animals to adapt. The physiological parameters of cloacal temperature (CT), respiratory rate (RR) and average surface temperature (AST) were recorded weekly (7:00 am, 10:00 am, 1:00 pm, 4:00 pm, and 7:00 pm); after solid and water fasting, the birds were slaughtered to assess the absolute weight of the organs. The time of day influenced (p < 0.05) the physiological parameters RR and AST, and CT showed a significant effect (p < 0.05) of increasing levels of digestible threonine. The total weight of the pancreas, proventriculus and lung showed a significant effect (p < 0.05) of the increase in the levels of digestible threonine. The respiratory rate is affected by the levels of threonine in the diet. The 0.687% level promoted hypertrophy of the pancreas, proventriculus and lung, promoting more significant activity of these organs.

This study examined the inclusion of untreated or urea-ammoniated CGT on the chemical composition, pH, gas, and effluent losses, dry matter recovery (DMR), and aerobic stability of elephantgrass silage. The experiment was laid out in a randomized design with a 3 × 3 factorial arrangement represented by three levels of inclusion of CGT during ensiling (0, 5, or 10%) and three levels of ammoniation of CGT with urea before ensiling (0, 4 or 8% for 28 days), using four replications. Data were subjected to analysis of variance and Tukey's test, considering a 5% significance level. The pH and DM, NDIN, ADIN, NDF and ADF contents of the silages increased (p < 0.05) with the inclusion of CGT, regardless of ammoniation. The lowest (p < 0.05) effluent loss was achieved using 10% of CGT ammoniated with 8% urea. In contrast, the elephantgrass silage exhibited the lowest (p < 0.05) gas loss and the greatest (p < 0.05) DMR. The inclusion of CGT compromised the aerobic stability of the silage. Therefore, the inclusion of CGT – either untreated or ammoniated – in the ensiling of elephantgrass is not recommended.

Infectious bronchitis (IB) is considered one of the most important poultry diseases worldwide. Many cases have been presented in Sri Lanka with similar clinical symptoms to those of IB in poultry belt areas. Therefore, the present study aimed to develop the IBV rapid detection methods using commercial insulated isothermal Polymerase Chain Reaction (iiPCR) and enzyme-linked immunosorbent assay (ELISA) in broilers, commercial layers, and backyard poultry flocks in Sri Lanka. Tracheal swabs and blood samples (n=413) were collected from vaccinated (n=107) and unvaccinated (n=306) birds exhibiting clinical signs attributable to IBV. Viral RNA was extracted from tracheal swabs and IBV was detected by iiPCR. Serum was separated from blood samples, and ELISA detected antibodies against IBV. It was reported that 46% (190/413) of birds were serologically positive for IBV by ELISA and 41.88% (173/413) of birds were positive for IBV by iiPCR. The total prevalence of IBV was 20.56% (22/107) of vaccinated and 49.34% (151/306) of unvaccinated poultry flocks by iiPCR. Furthermore, ELISA detected 30.84% (33/107) of vaccinated and 51.30% (157/306) of unvaccinated poultry flocks. Thus, IBV was more prevalent in unvaccinated birds comprised of backyard chickens and broilers in sampled areas. Moreover, the Batticaloa district had the highest prevalence of IBV (>75%). Thus, iiPCR assay could be used for rapid detection of IBV infection in clinical requirements.

Radish is an edible root vegetable belonging to the Brassicaceae family. It is a vegetable that matures quickly and is simple to grow. More farmers are switching to use of organic manure as a result of rising knowledge of the risks associated with chemical fertilizers. A field experiment was conducted at the University of Colombo Institute for Agro-Technology and Rural Sciences in Hambantota, Sri Lanka, to evaluate the effects of several organic preparations on the growth and yield of radish. Thirteen treatments were replicated four times following RCBD design. Different organic preparations namely Newly Modified Panchagavya (NMPG), fish tonic, compost tea and a commercially available preparation of Crop Master were used in various concentrations based on the previous research findings and recommendations. Water was applied as a control. Data on plant height, number of leaves, leaf length (cm), leaf width (cm), fresh leaf weight (g), fresh root weight of plant and total yield per treatment (Kg/ha) were recorded and analyzed statistically using ANOVA in SAS 9.1.3 package. The treatment means were compared using DMRT at 5% significance level. The results revealed that, application of NMPG had a significant higher effect on most of the tested parameters. Further, 4% of the NMPG showed better values compared to other concentrations. It was followed by the 3% and 2% of NMPG. Compost tea and crop master followed values next to NMPG. Based on the present findings it can be concluded that, Newly Modified Panchagavya can be used as organic application to cultivate Radish plants with a better growth and yield to obtain potential yield of radish.
