Authors: Xu Guangyu , Jiang Peijie , Xiong Bin
Published: September 2024

Goal 4 of the United Nations Sustainable Development Goals emphasizes ensuring inclusive and equitable quality education to achieve sustainability. It is well known that gifted mathematics education is crucial, but teachers for gifted mathematics education are extremely scarce. The promotion of sustainability in gifted mathematics education on a large scale is an important issue to ensure equity and quality in education. Mathematical competitions have always been an important method for gifted education and have received widespread attention from students and parents. Many high school students prepare for these competitions through extracurricular gifted mathematics tutoring. With the advancement of science and technology and the outbreak of the COVID-19 pandemic in 2020, many tutoring courses have gradually turned to online courses. Online gifted mathematics education has become a model for developing gifted education. In this study, we conducted an in-depth analysis of the learning patterns, grades, and family backgrounds of students participating in mathematics competitions in 10 key high schools in Liaoning Province from 2018 to 2024. The research results are as follows: (1) Before the COVID-19 pandemic, extracurricular gifted mathematics education primarily consisted of offline courses. During the COVID-19 pandemic, online learning resources developed rapidly and became prevalent, while offline education decreased. (2) Students from high-income families preferred offline courses when participating in extracurricular gifted education tutoring for mathematics. In contrast, students from middle- and low-income families were more inclined to choose online courses. Household registration and the place of residence had a weak correlation with the time spent participating in online gifted mathematics education. Among the influencing factors, material resources such as computers, smartphones, and broadband internet had a significant mediating effect. (3) With the advent of online education, the correlation between mathematics competition achievements and family income significantly decreased. However, students from rural families face challenges in accessing online education due to a lack of material resources consequent to the COVID-19 pandemic, resulting in lower mathematics competition achievements. The results show that online gifted education in mathematics breaks through the limitations of time, space, and resources; solves the problem of scarce teaching staff; and helps promote a comprehensive strategy for sustainable development in gifted education. At the same time, issues such as the digital divide, insufficient hardware, and limited internet access still need to be addressed.
Green Messaging in the Fast-Food Industry: The Role of Responsibility, Obligation, and Values in Driving Eco-Conscious Behavior
Authors: Liu Congying , Jiang Mingdi
Published: September 2024

This study aims to investigate how sustainability communication on social media, by retail fast-food chains, affects fast-food consumer behavior in terms of ascribed responsibility, felt obligation, and green values for the promotion of sustainable actions. Data-based evidence from fast-food customers in Malaysia established that sustainability communication increases the awareness of responsibility and moral obligation to behave sustainably. The findings of this study show that sustainability communication by retail fast-food chains leads to the improvement of the eco-conscious behavior of fast-food consumers. This relationship is mediated by psychological factors such as ascribed responsibility and felt responsibility and moderated by green values. The results of this study show that Malaysian customers who feel more responsible and obligated are likely to participate in sustainable behaviors. Furthermore, the high levels of green values enhance the impact of sustainability messages, meaning that sustainable communication can indeed change consumer behavior. This study supports the role of social media in improving the communication of sustainability and adapting the message to consumers’ values. These findings offer useful insights for fast-food firms that wish to enhance their sustainability initiatives and support the overall goals of sustainable development. This research also enhances the theoretical knowledge by incorporating both psychological and value-based factors into the model of sustainability communication, providing further insights into the effects of the factors on consumer behavior. This research thus offers a theoretical extension to the sustainability communication literature by considering psychological and value-based factors and offers practical implications for fast-food chains to enhance their sustainability communication and support sustainable development goals.

Authors: Zhang Ning , Li Haisheng
Published: September 2024

Considering the dataset of information related to Chinese coal-fired thermal power plants during the 2005–2017 period, we initially investigated the orthogonalized response of the carbon emission to energy consumption and power generation by using Bayesian vector autoregressions and feedback solutions for impulse control technology. The results showed that the effects of energy consumption and power generation on carbon emissions were significant. The Chinese government has launched a program aimed at curbing carbon emission peaks and neutralizing or decreasing carbon emissions. The causal relationship concludes that China still needs further investment in emission abatement, improvement related to the level of openness to the outside world, and the strengthening of the construction of green zones for industrial transfer to mitigate carbon emissions.
The Magnitude of Temporal–Spatial Gait Asymmetry Is Related to the Proficiency of Dynamic Balance Control in Children with Hemiplegic Cerebral Palsy: An Analytical Inquiry
Authors: Elnaggar Ragab K.
Published: September 2024

Children with hemiplegic cerebral palsy (hemi-CP) frequently experience deficits in dynamic balance, a crucial factor influencing gait function. This imbalance can manifest as temporal–spatial gait asymmetry, where movement patterns differ between the affected and less affected sides. This study investigated how temporal–spatial gait asymmetries and dynamic balance are associated in children with hemi-CP. Eighty-five children with hemi-CP (age: 13.27 ± 1.72 years) were included. The temporal (AITemporal) and spatial (AISpatial) gait asymmetry indices were, respectively, computed with reference to the swing time and step length of affected and less affected sides, which were collected through a 3D gait analysis. Measures of dynamic balance included the directional dynamic limit-of-stability (D-LOSdirectional) assessed across multiple directions (forward, rearward, affected, and less affected) and the overall dynamic limit-of-stability (D-LOSoverall) during static stance, in addition to the heel-to-heel base of support (BOSH-to-H) during walking, the dynamic gait index (DynGI), and the Timed Up and Down Stair (TUDS) test.The D-LOSoverall correlated negatively with the temporal (r = −0.437, p < 0.001) and spatial (r = −0.279, p = 0.009) asymmetries. The D-LOSdirectional (forward, rearward, affected, and less affected) correlated negatively with temporal asymmetry (r ranged from −0.219 to −0.411, all p < 0.05), but only the D-LOSdirectional rearward (r = −0.325, p = 0.002) and less affected (r = −0.216, p = 0.046) correlated with spatial asymmetry. The BOSH-to-H correlated positively with both temporal (r = 0.694, p < 0.001) and spatial (r = 0.503, p < 0.001) asymmetries. The variation in D-LOSoverall and BOSH-to-H accounted for 19.1% and 48.2%, respectively, of the variations in the temporal asymmetry and 7.8% and 25.3% of the variations in the spatial asymmetry. The findings of this study suggest that dynamic balance control is related to the magnitude of temporal–spatial gait asymmetries in children with hemi-CP. This evidence lays the groundwork for further research into the mechanism linking gait asymmetry and dynamic balance, potentially leading to a deeper understanding of these impairments, while also highlighting the need for longitudinal studies with the inclusion of a broader population to enhance the generalizability of the findings.

Aflatoxin constitutes a significant concern for food and feed safety, posing detrimental health risks to both animals and humans. This study aimed to examine the prevalence and concentration of aflatoxins in maize feed, total mixed ration, and wheat bran collected from specialized dairy farms and local markets in three major urban centers in eastern Ethiopia. A total of 180 feed samples were collected from September 2021 to January 2022 in Chiro town, Dire Dawa city, and Harar city. These samples underwent thorough extraction and immunoaffinity clean-up before aflatoxin analysis using HPLC/FLD. The results revealed that AFB1, AFB2, AFG1, AFG2, and TAF contamination was detected in 72.2%, 66.1%, 71.1%, 68.7%, and 82.8% of the feed samples, respectively. The corresponding mean levels of each aflatoxin were 28.15 ± 3.50, 3.3 ± 0.40, 19.87 ± 1.87, 2.7 ± 0.32, and 54.01 ± 4.72 µg/kg, respectively. The occurrence and levels of aflatoxin varied across different study sites and feed types. Notably, feeds from Dire Dawa city exhibited significantly higher mean levels of AFB1 (43.98 ± 5.3 µg/kg), AFB2 (5.69 ± 0.6 µg/kg), AFG1 (32.25 ± 2.7 µg/kg), and AFG2 (5.01 ± 0.5 µg/kg) than feeds from other urban centers did. Additionally, a significantly higher occurrence of AFB1 (29.4%) and AFG1 (28.3%) was detected in feed from Dire Dawa city. Similarly, the total mixed ration (TMR) displayed significantly higher levels of AFB1 (50.67 ± 5.2 µg/kg), AFB2 (4.74 ± 0.6 µg/kg), AFG1 (32.87 ± 2.6 µg/kg), and AFG2 (3.86 ± 0.5 µg/kg) compared to the other feed types. Moreover, a significantly higher occurrence of AFB1 (30.7%) and AFG1 (28.7%) was detected in the TMR. Furthermore, a moderate correlation was observed between the count of aflatoxigenic Aspergillus species and the levels of TAF in the feed samples. Overall, this study underscores the widespread presence of aflatoxin contamination in dairy feeds in eastern Ethiopia, highlighting the urgent need for stringent monitoring and mitigation measures to ensure food and feed safety, as well as public health.

(1) Background: Liver damage is an important component of acute COVID-19, and the advancement of preexisting liver disease is associated with a worse prognosis; (2) Methods: A nationwide retrospective study including 7444 patients aimed to evaluate levels of selected markers of liver damage and disease advancement and their association with mortality and mechanical ventilation (MV); (3) Results: Elevation of the following markers in multivariate models were associated with increased odds of mortality: Alanine transaminase (ALT), aspartate transaminase (AST), gamma-glutamyltransferase (GGT), lactate dehydrogenase (LDH), fibrosis-4 score (FIB-4), AST-to-platelet ratio index (APRI), and decreased levels of platelet count (PLT). Elevated levels of AST, LDH, APRI, FIB-4, and the AST/ALT ratio and decreased levels of PLT were associated with increased odds of MV in multivariate models. The best predictive accuracy against mortality was achieved with FIB-4 with AUC = 0.733 (95% CI, 0.718–0.749) at the optimal cut-off point of 2.764, while against MV was achieved with LDH with AUC = 0.753 (95% CI, 0.727–0.778) at the optimal cut-off point of 449.5 IU/L. (4) Conclusions: Our study confirms that the advancement of liver damage contributes to a worse prognosis in COVID-19 patients. Markers for liver damage and the advancement of liver disease can provide predictive value in clinical practice among COVID-19 patients.

Agricultural pests can cause direct damage to crops, including chlorosis, loss of vigor, defoliation, and wilting. In addition, they can also indirectly damage plants, such as by transmitting pathogenic micro-organisms while feeding on plant tissues, affecting the productivity and quality of crops and interfering with agricultural production. Among the known arthropod pests, mites are highly prevalent in global agriculture, particularly those from the Tetranychidae family. The two-spotted spider mite, Tetranychus urticae, is especially notorious, infesting about 1600 plant species and causing significant agricultural losses. Despite its impact on agriculture, the virome of T. urticae is poorly characterized in the literature. This lack of knowledge is concerning, as these mites could potentially transmit plant-infecting viral pathogens, compromising food security and complicating integrated pest management efforts. Our study aimed to characterize the virome of the mite T. urticae by taking advantage of publicly available RNA deep sequencing libraries. A total of 30 libraries were selected, covering a wide range of geographic and sampling conditions. The library selection step included selecting 1 control library from each project in the NCBI SRA database (16 in total), in addition to the 14 unique libraries from a project containing field-collected mites. The analysis was conducted using an integrated de novo virus discovery bioinformatics pipeline developed by our group. This approach revealed 20 viral sequences, including 11 related to new viruses. Through phylogenetic analysis, eight of these were classified into the Nodaviridae, Kitaviridae, Phenuiviridae, Rhabdoviridae, Birnaviridae, and Qinviridae viral families, while three were characterized only at the order level within Picornavirales and Reovirales. The remaining nine viral sequences showed high similarity at the nucleotide level with known viral species, likely representing new strains of previously characterized viruses. Notably, these include the known Bean common mosaic virus (BCMV) and Phaseolus vulgaris alphaendornavirus 1, both of which have significant impacts on bean agriculture. Altogether, our results expand the virome associated with the ubiquitous mite pest T. urticae and highlight its potential role as a transmitter of important plant pathogens. Our data emphasize the importance of continuous virus surveillance for help in the preparedness of future emerging threats.

Background: Despite its global eradication in 1977, smallpox remains a concern owing to its potential as a biological agent, thereby prompting the ongoing development and utilization of its vaccine. Vaccination with the Vaccinia virus induces immunity against variola virus, the causative agent of smallpox; however, this immunity does not extend to viruses of different genera within the Poxviridae family. In this study, we aimed to assess the efficacy of an enzyme-linked immunosorbent assay (ELISA) method utilizing Vaccinia virus and recombinant A27L antigen for detecting antibodies against smallpox. Methods. An analysis of the serum from 20 individuals pre- and post-vaccination with the CJ strain (CJ50300) revealed neutralizing antibodies, which were confirmed using the plaque reduction neutralization test (PRNT). The ELISA method, validated with a PRNT50 cut-off value of >4, exhibited a sensitivity and specificity of >95% and was particularly reactive with the inactivated virus. Furthermore, adherence to the smallpox vaccination policy revealed significant differences in Orthopoxvirus antibody levels among 300 individuals of different age groups. These findings highlight the reliability and efficacy of the ELISA method in detecting post-vaccination antibodies and contribute significantly to diagnostic methods to prepare for potential smallpox resurgence and bioterrorism threats.

Published: September 2024

Staphylococcus aureus (SA) is a major bacterial pathogen and causes a wide range of clinical infections in humans leading to severe outcomes including meningitis, endocarditis, and sepsis. This literature review examines studies on host immune responses after infections with SA and methicillin-resistant Staphylococcus aureus (MRSA) and their immune evasion mechanisms. Furthermore, information about vaccines and immunotherapies against SA and MRSA is reviewed. We found promising toxoid vaccine approaches, which deserve further research. We also found support for antitoxin therapies and immunomodulating therapies as high-potential research areas. Although many promising vaccines and immunotherapy candidates have been studied in animal models, more human clinical studies are needed to confirm their long-term safety and efficacy.

The variation in the population of pathogenic microorganisms in wastewater over time can be predicted by single-spectral analysis, which outperforms conventional multivariate methods. This type of information is important for the performance of sewage treatment plants. The objective of this study was to monitor the variability of the population of microorganisms and the removal of microbiological attributes of sanitary wastewater in a treatment plant equipped with a septic tank and solar reactor. Effluent samples were collected monthly upstream of the septic tank and inside the solar reactor, and the effluent was exposed to solar radiation. Total coliforms and Escherichia coli were analyzed by means of descriptive analysis and singular spectrum analysis. Solar disinfection obtained bacterial inactivation levels of 99.94%, equivalent to 4 log units for the Escherichia coli population, and 99.45%, equivalent to 3 log units for the total coliform population. For the inlet effluent, the prediction showed a trend of growth alternating with periods of stability. For the outlet effluent, the prediction was able to provide regular data up to the first six months, showing error and overestimation of the data for the final six months of the study.

Published: September 2024

Displacement prediction models based on measured data have been widely applied in structural health monitoring. However, most models neglect the particularity of displacement monitoring for arch dams with cracks, nor do they thoroughly analyze the non-stationarity and uncertainty of displacement. To address this issue, the influencing factors of displacement were first considered, with crack opening displacement being incorporated into them, leading to the construction of the HSCT model that accounts for the effects of cracks. Feature selection was performed on the factors of the HSCT model utilizing the max-relevance and min-redundancy (mRMR) algorithm, resulting in the screened subset of displacement influence factors. Next, displacement was decomposed into trend, seasonal, and remainder components applying the seasonal-trend decomposition using loess (STL) algorithm. The multifractal characteristics of these displacement components were then analyzed by multifractal detrended fluctuation analysis (MF-DFA). Subsequently, displacement components were predicted employing the convolutional neural network-long short-term memory (CNN-LSTM) model. Finally, the impact of uncertainty factors was quantified using prediction intervals based on the bootstrap method. The results indicate that the proposed methods and models are effective, yielding satisfactory prediction accuracy and providing scientific basis and technical support for the health diagnosis of hydraulic structures.

Published: September 2024

Organic saline wastewater has become a concern in recent decades due to its resistance to biological treatment and potential harm to municipal wastewater treatment plants. While photocatalytic methods have been used for treatment, they often lead to catalyst deterioration. The use of salt-tolerant catalysts presents a viable solution for treating organic saline wastewater. In this study, a Zn-rich g-C3N4 was synthesized, demonstrating excellent performance in removing 2,4-DCP and its derivatives from saline wastewater. More than 75.6% of 2,4-DCP was effectively removed with the addition of Zn-rich g-C3N4, nearly doubling the removal rate compared to pure g-C3N4 and those doped with Co, Ag, Mo, and Bi. Notably, the removal efficiency of 2,4-DCP slightly increased as salinity rose from 0.1 to 2.3 wt.%. Adding 0.1 g L−1 of Zn-rich g-C3N4 resulted in the removal of 2,4-DCP, 2-chlorohydroquinone, chloroacetophenone, and 2-chloropropionic acid by 99.3%, 99.8%, 98.2%, and 99.9%, respectively, from a real saline wastewater sample with 2.2 wt.% salinity, corresponding to a 67.7% removal of TOC. The EPR results indicated that Zn-rich g-C3N4 generated more free radicals compared to pure g-C3N4, such as·OH and Cl, to degrade organic contaminants. The degradation pathway revealed that 2,4-DCP was first dechlorinated into p-phenol and catechol, which were subsequently degraded into maleic acid/fumaric acid, trihydroxyethylene, acetic acid, oxalic acid, and other products. Furthermore, Zn-rich g-C3N4 demonstrated excellent stability and holds promising potential for applications in saline wastewater treatment.

Dihydroquercetin (DHQ) is a natural flavonoid. It is a promising object for the development of new remedies due to its wide range of pharmacological activity and high safety profile. The structure of this compound is characterized by the presence of two chiral centers, allowing it to exist as cis- and trans-diastereomers. The lack of reliable methods for controlling the stereochemistry of DHQ is a potential source of risk for consumers. The solution to this problem may be the development and implementation of a standard sample of its cis-diastereomer. Thus, the aim of this study was to carry out an analytical and experimental screening of synthetic approaches to obtain flavanonol with cis-configuration of asymmetric carbon atoms. The study used methods of catalytic hydrogenation of quercetin and isomerization of trans-DHQ. The progress of the reaction was monitored chromatographically. During hydrogenation of the quercetin alcohol solution, the concentration of the target product varied from 0 to 0.012 mg/mL. Adding a nickel-aluminum alloy as a catalyst results in a 0.3±0.2 % yield of cis-DHQ. Factors considered during the screening of the possibility of isomerization of the trans-diastereomer of the studied flavonoid into the cis-stereoisomer included temperature, pressure, solvent, and pH value of the medium. The yield of the target product reached 6.8±1.1 %. It was found that the increasing the temperature associates with higher yield of cis-DHQ (r2 = 0.4168), as well as increasing the pH value of the solution (r2 = 0.9308), while pressure had almost no effect on the epimerization process (r2 = 0.1999). Thus, the isomerization of trans-DHQ appears to be a more promising approach to obtaining its cis-isomer due to the greater uniformity of results and the ability to control the process.

Authors: Matytcina M. S. , Rychagova L. D.
Published: September 2024

Adaptive machine translation is a technology that combines the advantages of machine translation and human-made translation in order to improve the efficiency of the subtitle creation process. This paper shows how adaptive machine translation helps translators in their work on creating subtitles. The main idea is that adaptive machine translation algorithms offer preliminary translation variants to the translator, which are then edited and refined by a human. At the same time, the algorithms take the specifics of subtitles into account, such as a limit on the number of characters and a limited time to read lines. Adaptive machine translation is an important tool for creating high-quality subtitles. It helps translators in their work by facilitating and speeding up the translation process, improving the quality and preserving the style of the original text.

Published: September 2024

Medical students face a multitude of challenges including rigorous exams, exposure to diseases and death, and the stress and anxiety associated with preparing for the Medical Specialty Exam (MSE). We aimed to determine what are the primary reasons for vocational future concerns among intern doctors, and are there gender differences in the causes and levels of the concerns. This cross-sectional study was conducted at Ondokuz Mayıs University Faculty of Medicine between July 2019 and March 2020, and 148 interns whose informed consent was obtained were included in the study. The data were collected by 5-point Likert type scale for interns' future concerns, consisted of 15 items, and 3 subdimensions. The Cronbach’s alpha coefficient of the scale was 0.89. Of the 148 participants with a mean age of 23.9 years, 43.9% were male, and 56.1% were female. The main reasons for concern were "inability to prepare for the medical specialty exam (68%)" and "failure to pass the MSE (58%)". These had been followed by concerns about “compulsory service in the eastern regions", “dealing with medical emergencies”, and other professional incompetence. Few interns reported that they were worried about being unemployed (13%). We determined that the vocational concerns of the females were significantly higher than the males, especially about working in the eastern regions, medical emergencies, and clinical skills (p

Düzce ili Gölyaka ilçesinde 23 Kasım 2022 tarihinde TSİ 04:08’de moment büyüklüğü (Mw) 6,0 olan orta büyüklükte bir deprem meydana gelmiştir. Deprem başta Düzce ili olmak üzere Karadeniz, Marmara ve İç Anadolu bölgelerinde de şiddetli bir şekilde hissedilmiştir. Orta büyüklükte meydana gelen bu deprem sonucunda en büyük yer ivmesi yaklaşık 14 km uzaklıktaki 8105 istasyonunun Doğu-Batı bileşeninde 592 gal olarak kaydedilmiştir. Bu çalışma kapsamında ilk olarak 2022 Düzce depremi öncesi bölgede meydana gelen depremlerin zamansal ve mekânsal değişimi incelenmiştir.

Published: September 2024

Optimizing irrigation practices is crucial to ensure that plants receive the correct amount of water while minimizing inefficiencies resulting from deep percolation or drainage. This article introduces a smartphone application that accurately predicts the timing and duration of irrigation for various crops in Malaysia. The app uses locally calibrated crop coefficients, Maximum Allowed Depletion factors, and local formulas to calculate effective rainfall and evapotranspiration. This allows us to identify the most efficient irrigation cycle for each selected crop in Peninsular Malaysia. The application is a pioneering tool that considers meteorological conditions, precipitation, and plant water stress to determine the most efficient irrigation cycles for crops grown in the selected area. Additionally, this smartphone application is the first tool capable of calculating effective rainfall for any designated geographical area in Peninsular Malaysia. This represents a significant advancement for farmers, offering them cutting-edge precision farming tools that enhance the efficiency of their irrigation cycle. This program contributes to reducing water waste and enhancing crop yields by providing precise estimations of irrigation frequency and runtime. By applying the same approach, this app could also be extended to other Southeast Asian countries.

Poultry birds consume coated pelletized feed more than mashed or crumbs. For optimum performance, it is very important to use oils/grease that has quality nutrients to coat the pellets. Also, oils that are of less competition with humans and industries will reduce the cost of production. Chrysophyllum albidum oil is one such oil that has not been explored enough. It has been shown that the oil is composed of all the essential amino acids needed by broiler birds and exhibit characteristics that make it suitable as preservatives in animal feed. Pelletized (5mm) feed was coated with Palm Kernel oil (PK), Chrysophyllum albidum kernel oil (CAK) and a combination of the oils at the rate of 1 liter/100 kg of feed. Totally, 120 chicks of day-old age were used for the experiment. All data obtained were subjected to ANOVA and significant differences were compared using the Duncan multiple range test. It was observed, that the physical qualities of CAK oil contributed to the attractiveness of the pellets, which, in turn, increased feed intake and more flesh deposition by birds on T3 (feed coated with CAK alone). The synergy of CAK and PK oils was able to utilize the feed (FCR − 2.80) significantly (P < 0.05) better than the individual oil. The haematology and serum biochemistry results of all the treatments fell within the range for normal physiological and nutritional stable chicken. There were indications that CAK oil had advantages over the PK oil. It can be concluded that CAK oil can successfully replace PK oil in broiler pellets for optimum performance. It exhibits potential to serve as natural preservatives in feed and its amino acid profile served as added advantage. Its inclusion in feed did not pose any negative effect on physiological and nutritional status of the experimental birds. Limitations to this study include access to funds, as this study was self-sponsored. Also, the inconsistence weather conditions prolonged the estimated time for drying the kernels.

Weaning is one of the most stressful events in pigs as this affects their health, growth performance and welfare especially during the first week post-weaning. Early weaning exposes weanling pigs to severe weaning stress. Therefore, this study assessed the effects of different weaning regimes on weanling pigs' growth, stress and behavioural responses. Seventy-two weanling pigs, allotted to three treatments in 6 replicates in a completely randomised design, were used for this study. The weanling pigs were weaned at four weeks (T1), six weeks (T2) and eight weeks (T3) and involved in the study immediately after weaning. Growth performance (feed intake, weight gain and feed conversion ratio − FCR), stress indices (corticosterone, white blood cell − WBC) and behavioural indices (feeding and aggressive behaviour) were measured for 6 weeks, twelve days and ten days post-weaning, respectively. Data were analysed using descriptive statistics and ANOVA at α 0.05. Feed conversion ratio of weanling pigs in T1 (2.42 ± 0.09) was significantly higher (p < 0.05) than in T2 (2.23 ± 0.15) and T3 (2.22 ± 0.10) groups. Corticosterone concentration in the weanling pigs ranged from 55.83 ng/ml (T1) to 48.31 ng/ml (T3) on day 3, from 45.58 ng/ml (T2) to 45.42 ng/ml (T1 and T3) on day 9, and from 46.52 ng/ml (T1) to 45.25 ng/ml (T2) on day 12. The white blood cell (WBC) count in the weanling pigs in T1 (8.83 ± 0.07 × 103 µl) was significantly higher (p < 0.05) than in T2 (8.53 ± 0.12 × 103 µl) and in T3 (8.62 ± 0.14 × 103 µl) on day 0. The values obtained for days 6, 9 and 12 demonstrated the same trend. Feeding behaviour showed that weanling pigs in T1 spent lesser time feeding than in T2 and T3 groups. The values ranged from 41.72 % (T1) to 70.31 % (T3). Weanling pigs in the T1 group showed more aggression towards pen mates for the first 3 days compared to T2 and T3 groups. The values ranged from 0.52 % (T3) to 9.24 % (T1). In conclusion, this study revealed that different weaning regimes have varying effects on the performance and welfare of pigs. It is important to carefully consider the weaning regimes implemented in pig production to minimize stress and promote healthy growth.

The utilization of unconventional feed resources in broiler production as a means of reducing costs associated with feed has been continually explored over the years. Nevertheless, there is a dearth of information on the use of wilted waterleaf (Talinum triangulare) in this regard. Thus, this trial which lasted for 6 weeks was conducted to evaluate the effect of supplementing a basal diet formulated to meet the requirement of the broiler chicken with varying levels of wilted waterleaf (WL) at 0 g/kg, 5 g/kg and 10 g/kg. One hundred and fifty (150) day-old Arbor Acre broiler chickens were randomly allotted to 3 dietary treatments (T1: 0 g/kg, T2: 5 g/kg, and T3: 10 g/kg) with 5 replicates per treatment and 10 birds per replicate in a Completely Randomized Design (CRD). Results obtained revealed that birds fed diet T3 had the highest final weight and weight gain. Feed conversion ratio was statistically similar for both diet T2 (1.69) and T3 (1.67) compared to diet T1 which had the highest feed conversion ratio (1.71). Haematological parameters showed that only mean corpuscular volume, mean corpuscular haemoglobin, lymphocyte and granulocytes were significantly (p < 0.05) influenced by dietary treatments while others were unaffected. There were no significant (p > 0.05) differences among all serum biochemical indices evaluated. The results obtained from this study suggested that supplementing broiler chicken diets up to 10 g/kg waterleaf can significantly improve performance and haematological parameters and could be adopted by broiler farmers for maximum productivity of farms.
