title: Performance of piglets according to colostrum intake and serum immunoglobulin concentration determined by the immunocrit method

description: ABSTRACT: Colostrum is the main source of immunoglobulins for piglets and several studies have shown that colostrum intake by piglets have a significant influence on their immunity as well as their future performance. The aim of this study was to ascertain the correlation between colostrum intake in the first 24 hours and the serum immunoglobulin concentration determined by immunocrit (IR), determine if the birth order of piglets interfered in colostrum intake and the IR, and measure their weight gain up to 42 days of age. One hundred and three piglets were included in the study and divided into two groups according to colostrum intake in the first 24 hours: &gt; 230 g and &lt;230 g. Piglets with an intake of (230 g colostrum at birth had a mean weight of 1.412 ± 0.156 kg (mean ± SEM) while animals with a colostrum intake &lt;230 g weighed 1.317 ± 0.162 kg (P&gt;0.05). The mean IR between colostrum intake groups was 0.075 (&lt;230 g) and 0.096 ((230 g) (p&lt;0.05). The IR differed between the order of birth of the piglets; where piglets born up to ≤7 had an IR=0.096 while those born from &gt;7 presented with an IR=0.079 (p&lt;0.05). Piglets that consumed more colostrum (&gt;230 g) in the first 24 hours after birth had a greater immunocrit and greater weight gain from 7 to 42 days of age (p&lt;0.05). We concluded that the order of birth does not affect the colostrum intake, but the IR has a negative correlation (CORR= -0.3101; p&lt;0,05) with the order of birth. Piglets with intake of more than 230 g of colostrum show greater weight gain up to 42 days of age.

title: Farmers’ perception of agricultural cooperatives: the case of Şanlıurfa, Turkey

description: ABSTRACT: Şanlıurfa is the province with the third-largest agricultural area in Turkey. However, it has only 0.62% of the total number of cooperatives in the country. This study aimed to determine the perceptionsof farmers in Şanlıurfa regarding agricultural cooperatives and the factors affecting them. The main research material was obtained through face-to-face surveys involving farmers in Şanlıurfa selected by a simple random sampling method. The sampling volume was determined with a 95% confidence limit and a 5% error margin. Multiple regression analysis was used in Stata software. According to the results of the research, 39.7% of the participants were cooperative members and more than half of them were not active members. Of the participants, 30.3% had a positive perception of cooperatives, 36.82% were undecided, and 32.88% had negative opinions. Age, marital status, non-agricultural income, experience, social security, farmer registration system, cooperative membership, and land variables positively affected farmers’ perceptions. However, the variables of education, income, and union membership had negative effects on farmers’ perceptions. No statistically significant relationship was reported between a farmer’s perception and any of the following variables: the number of people that make up the farmer’s household, the number of individuals engaged in agriculture and non-agricultural work in the family, and the status of the farmer’s lease. Conceptual, local, cultural, educational, and structural problems related to cooperatives exist in Şanlıurfa.These issues need to be given more attention by the public. This research is the first study on this subject to be conducted in Şanlıurfa.

title: Prednisolone associated with doxycycline on the hematological parameters and serum proteinogram of dogs with ehrlichiosis

description: ABSTRACT: The objective of the present study was to assess the treatment of dogs with ehrlichiosis (tropical canine pancytopenia (TCP)) with doxycycline hydrochloride associated or not with prednisolone on the hematological profile and serum proteins. Ten dogs with TCP were selected in the Small Animal Medical Clinic Veterinary Hospital, Federal University of Campina Grande-UFCG-PB, Brazil. The diagnosis was obtained by clinical examination, hemogram and immunochromatographic test (with anti Ehrlichia canis antibodies). Samples were distributed randomly in two experimental groups of five animals each (n = 5), named GD and GDP. The GD group was treated with doxycycline (5 mg/kg, VO, BID for 28 days) and the GDP group was treated with doxycycline at the same dose and duration and prednisolone (2 mg/kg, VO, BID, for five days). Four blood collections were made during the treatment period: a base collection (M0), one at 10 days (M10), a second at 21 days (M21) and another at the end of the treatment (M28). These samples were used for the tests erythrogram, leucogram, plateletgram and proteinogram (dose of total proteins, pre-albumin, albumin, albumin, α-1 globulin, α-2 globulin, ß-globulin, ɣ-globulin and C- reactive protein) in the Clinical Pathology Laboratory, Veterinary Hospital-UFCG-PB. Results, that presented normal distribution, was submitted to the Tukey test (P&lt;0.05). Comparison of treatments GD and GDP showed that both promoted discreet and similar response in the hematological parameters at different times. Results obtained allowed the conclusion that both therapeutic protocols resulted in clinical, hematological parameter and proteinogram improvement, but the use of prednisolone at the dose administered during the first five days of treatment did not show more beneficial effects than isolated administration of doxycycline.

title: Hematological, clinical and epidemiological aspects of Hepatozoon canis infection by parasitological detection in dogs from the rural area of Sousa, Paraíba, Brazil

description: ABSTRACT: Hepatozoonosis is caused by protozoa of the genus Hepatozoon. In dogs, the infection is caused mainly by Hepatozoon canis, and there are a few descriptions of the prevalence of this infection in the Northeast region of Brazil, especially in the semi-arid region. Therefore, we aimed to determine the prevalence of Hepatozoon canis infection in dogs in the rural area of Sousa, Paraíba, Brazil, as well as to determine the possible clinical and epidemiological aspects of this infection. Ninety-eight dogs in the rural zone of the municipality of Sousa that were at least 4 months old were evaluated, regardless of their breed or gender. Clinical examinations were carried out, and samples of systemic and peripheral blood were collected to determine the presence of the parasite in blood smears and carry out hemograms. In addition, epidemiological questionnaires about animal health and food management were completed. The prevalence of H. canis infections in dogs was 8.1% (8/98). There were three main changes in the hematological status: thrombocytopenia, anemia and hyperproteinemia, mainly related to percentage of leukocyte infection ≥5%, and also to the presence of clinical signs such as mucopurulent secretion, lymphadenomegaly, dry skin, pale mucous membranes, and lean or cachectic body score.

title: Physicochemical and sensory evaluation of mortadella based on Nile tilapia filleting residues

description: ABSTRACT: The objective of this research was to elaborate and characterize mortadella using fillet residues (‘V’-cut fillet trim) of Nile tilapia, in order to add value to this by-product of the filleting process. Three mortadellas were made, one with 100% tilapia fillet trimmings, another containing 100% chicken meat and the third with 100% pork meat. Mortadellae were characterized in terms of microbiology, chemical composition, calcium, collagen, pH, Aw, colour, texture and formulation cost. Mortadella was within the recommended microbiological standards. Tilapia mortadella had higher levels of moisture, ash, calcium and collagen, higher pH and lower water activity when compared to other species. The tilapia mortadella had lower brightness, higher chroma a * and intermediate chroma b *, compared with the others. The texture of tilapia mortadella was better in terms of hardness, gumminess and chewability, the values of which were lower. The chicken mortadella had a higher acceptance rate; however, that of tilapia was also high, while all evaluated attributes of pork received the worst grades. Nile tilapia mortadella is a technological innovation that can be introduced into the food sector with good nutritional value and a good acceptance index.

title: Epidemiological and pathological aspects of salmonellosis in cattle in southern Brazil

description: ABSTRACT: Salmonellosis is a bacterial disease that affects several domestic animal species, and is commonly diagnosed in cattle, horses, and pigs. This study aimed to describe the epidemiological and pathological findings of eleven cases of enteric salmonellosis and two cases of salmonellosis with pulmonary involvement in cattle in Rio Grande do Sul State, Brazil. Clinical signs included fever, yellow diarrhea, sometimes with blood streaks, and dyspnea, with a clinical course ranging from 1 to 30 days. Eight cases occurred as outbreaks, whereas five cases occurred individually. Risk factors included inadequate handling practices, such as overcrowded facilities and comorbidities, including anaplasmosis. The main gross finding of the enteric presentation was fibrinonecrotic enterocolitis, occasionally associated with button ulcers, mesenteric lymphadenomegaly, splenomegaly, cholecystitis and hepatomegaly. In addition, one steer with a chronic clinical progression presented severe segmental thickening of the ileum, associated with intestinal rupture and peritonitis. In the respiratory system, the main findings were reddened, non-collapsed lungs, with multifocal areas of atelectasis. The main microscopic findings were observed in the small and large intestines, and these were characterized by severe necrosis and mucosal ulceration, associated with marked inflammatory infiltrate of neutrophils and fibrin deposition intermixed by rod-shaped bacterial aggregates, and fibrosis, as well as interstitial pneumonia. Seven cases yielded positive bacterial cultures for Salmonella spp. and three serovars, namely Typhimurium, Dublin, and Panama were identified. All cases exhibited immunolabeling for Salmonella spp. using immunohistochemistry.

title: Light sources on the germination and initial in vitro establishment of Schomburgkia crispa Lindl., a species of the Brazilian Cerrado

description: ABSTRACT: Light is one of the factors that influence the germination and initial establishment of orchids under in vitro cultivation. This study evaluated the effect of different light sources on these stages in in vitro cultivation of Schomburgkia crispa Lindl. After sowing in an aseptic environment, we stored the cultures in a screened greenhouse (natural light) or in a growth room with the following light sources: 3,000 K yellow LED; 6,500 K white LED [1]; 6,500 K white LED [2]; or 6,500 K white fluorescent lamp (control). We assessed germination percentage and initial seedling establishment at 45 and 90 days after sowing. Light did not influence the germination of S. crispa. However, the use of 3,000 K LED provided a faster initial establishment of S. crispa when compared to the other light sources, also presenting lower seedling mortality. Thus, the light source 3,000 K LED is a potential substitute for the 6,500 K fluorescent lamps and LEDs used in growth rooms in in vitro culture laboratories.

title: Water uptake dynamics in soybean seeds: influence in seeds performance and DNA integrity

description: ABSTRACT: Relationships among water uptake rate and temperatures were investigated in five soybean seeds lots cv. M 6410 IPRO. Germination, field emergence and electrical conductivity tests were applied to determine seed performance after fast (complete immersion in water), control (moist substrate) and slow (moist atmosphere) imbibitions both at 20 °C and 30 °C. The fresh weight increment over time in soybean seeds during imbibition was recorded. In parallel, analysis of the DNA integrity of seedlings obtained from such seeds was performed in gel electrophoresis. Absorption pattern of soybean seeds were similar among temperatures, but absorption characteristics vary with time progress according to the way of water entrance into the seeds. Upon fast imbibition seeds germinated lower than non-fast-imbibed seeds, besides loss of seed performance. In contrast, slow-imbibed seeds showed high germination, low abnormal seedlings and maintenance of seeds performance. DNA isolation from fast imbibed seeds was highly degraded; although, some considerably degraded samples were reported in controlled imbibed seeds and the best preserved DNA was found in slow-imbibed seeds. The pattern of DNA degradation is typically passive or non programmed cell death. Our results showed it is important to consider the water uptake rate during germination test, since DNA integrity plays a critical role during seed imbibition, preserving soybean seed performance.

title: Helicobacter spp. and gastric lesions association in minipigs

description: ABSTRACT: Due to their similarity to humans, studies regarding gastric ulcers in pigs have become of great interest. It is known that Helicobacter spp. is related to the occurrence of these ulcers, as they possess a high prevalence in pigs. This study aimed to associate gastric lesions findings naturally occurring in minipigs related to or not related to the presence of Helicobacter spp., through the ultra-rapid urease test and immunohistochemical analysis, reaffirming the disease in swine as a natural biomedical model for human cases. For this, samples of formalin-fixed paraffin-embedded gastric tissues from 40 minipigs were obtained at the Laboratório de Morfologia e Patologia Animal (LMPA) in the Universidade Estadual do Norte Fluminense (UENF). Regarding the ultra-rapid urease test, no animal was positive in all regions. However, 18 were positive in at least one: six (15%) were positive in the aglandular region, eight (20%) in the antrum region, 13 (32.5%) in the region of the cardiac gland, and one (2.5%) in the region of the fundic gland. Regarding immunohistochemical analysis, only one animal was positive in all regions, and 32 animals were positive in at least one: four (10%) were positive in the aglandular region, 10 (25%) in the antrum region, 23 (57.5%) in the region of the cardiac gland, and three (7.5%) in the region of the fundic gland. The gastric lesion findings showed a close relationship with Helicobacter spp., enriching the laboratory animal pathologies list. The immunostaining of the bacteria not associated with gastric lesions in certain regions demonstrated the saprophytic and opportunisitic nature of Helicobacter.

title: Morphophysiological characterization of Ceratocystis fimbriata isolates from yerba mate

description: ABSTRACT: This study aimed to morphologically characterize the isolates of Ceratocystis fimbriata from yerba mate and to evaluate the effect of culture medium and temperature on mycelial growth and sporulation of C. fimbriata. For the morphological characterization of the 11 monosporic isolates of the fungus, slides were prepared to determine the dimensions of the sexual and asexual structures of the fungus. Four experiments were conducted to evaluate the mycelial growth and to evaluate the sporulation of C. fimbriata in different culture mediums and temperatures. The isolates of C. fimbriata from yerba mate showed perithecia with brown to black necks, divergent ostiolar hyphae, hatshaped hyaline ascospores, single-celled, cylindrical endoconidia, and globular to ovoid aleurioconidia. PDA and V8-agar media showed the highest mycelial growth. The average optimum temperature for mycelial growth and sporulation of isolates of C. fimbriata of yerba mate were 22.5 and 22.4 ºC, respectively.

title: Seed size influences the promoting activity of rhizobia on plant growth, nodulation and N fixation in lima bean

description: ABSTRACT: This study evaluated the activity of rhizobia isolates inoculated in large (18 mm) and small (11 mm) seeds on lima bean growth, nodulation and N fixation. Selected rhizobia isolates were compared with a reference strain CIAT899 and two controls without inoculation. Large seeds contributed for highest plant growth, nodulation and N fixation than small seeds. The isolates UFPI-59, UFPI-18 and UFPI-38 promoted the highest values of shoot and root dry weight, respectively. The isolates UFPI-32 promoted the highest values of nodule number, while UFPI-59 promoted the highest values of nodule dry weight. The isolates UFPI-38 and UFPI-59 promoted the highest accumulation of N. This study showed that seed size really influences lima bean growth, nodulation and BNF. Considering rhizobia isolates, UFPI-59, UFPI-38, and UFPI-18 contributed for plant growth, promoted better nodulation and effectiveness on biological N fixation.

title: Logistical transportation routes optimization for Brazilian soybean: an application of the origin-destination matrix

description: ABSTRACT: The last Brazilian agricultural frontier known as MATOPIBA, an acronym for the states of Maranhão, Tocantins, Piaui and Bahia, is a region that has stood out in the scenario of modern large-scale agriculture intensive in capital and technology. However, barriers related to the transportation system, especially regarding the high logistics costs, have been negatively impacting this sector. To optimize the performance of this chain, a model for minimizing transportation costs was developed, using linear programming with an origin-destination matrix. The purpose of this paper was to evaluate whether the use of the North-South Railroad has potential as a new alternative intermodal route for soybean export from the MATOPIBA region, in order to minimize the transportation costs and promote the viability of new ports located in the northeast region of the country. This configuration can also contribute to reduce the overload of Santos Port (SP). Two scenarios were proposed based on the 2016/17 harvest of soybeanwhere the first scenario (A) consisted only of road routes, while the second (B), in addition to these routes, incorporated road-rail and road-water way intermodal routes. As a result, total transportation cost was reduced by 30% in scenario B and about half of all cargo was shipped by the new intermodal road-rail route to the Itaqui Port in the Northeast region. This configuration promotes a more sustainable logistics chain for soy, with more rational use of transport modes and decentralization of investments to other regions.

title: The potential of “umbuzeiro” genotypes for the development of preserves

description: ABSTRACT: One of the relevant economic importances of the “umbuzeiro” (Spondias tuberosa Arruda) to the northeastern semiarid region of Brazil is the fruit processing to obtaining preserves. However, there are limitations in the production and standardization of this product, such as color, taste and texture, which are problems in the quality, identity, making it harder to achieve new markets. This study was carried out aiming to evaluate the potential of “umbu” genotypes (Access 37, Access 44, BRS 48, BRS 52, BRS 55 and BRS 68) registered by Embrapa in the development of preserves. It was evaluated the product pH, total acidity, water activity, soluble solids, moisture, firmness, color (L*, a*, b*), reducing and non-reducing sugars, vitamin C, syneresis and consumer acceptance regarding the overall impression. The CATA method was applied to describe the sensorial profile of the samples. According to the results, it was observed a significant difference (p≤0.05) in the physico-chemical composition of the samples, being samples produced from the access 37 and BRS 68 more appropriated for processing of preserves (in bars), with greater firmness and less syneresis. Consumers indicated products from the genotypes 37, 44, BRS 52 and BRS 55 as the ones with highest acceptance regarding the overall impression; the consumers associated the samples in different characterizations, associating the access 37 and BRS 68 with the characteristics of firm and delicious; the commercial sample was characterized as acid, adstringent and terrible.

title: Crown rust on oat genotypes with different levels of resistance: damages and losses

description: ABSTRACT: The evolution in virulence of Puccinia coronata f. sp. avenae has challenged the genetic resistance to crown rust in oat genotypes. New resistance sources are constantly required for yield stabilization and costs reduction. This study aimed to characterize the crown rust resistance of oat genotypes and the disease´s productive and economic impact. Experiments were conducted in two environments, with and without chemical control. Resistance was measured by disease progress, apparent rate of infection, final severity and pustule size. Damages were based on reduction of yield, 1000 grain mass and hectoliter mass. UFRGS16Q6030-2 was immune. In both environments, UFRGS166091-2 and URS Brava exhibited the greatest level of resistance and the smallest grain yield reduction, while URS 22 was highly susceptible, reducing more than 70% of its grain yield. These results surpass the negative impacts of the disease previously reported in oats, particularly related to grain yield. The data presented in this paper highlighted the importance of genetic resistance, particularly partial resistance, for maintaining oat genetic yield potential, reducing environmental contamination with less fungicides, and increasing economic gains with oat cultivation.

title: Diagrammatic scales for the estimation of black node disease severity in common bean

description: ABSTRACT: The objective of this study was to design two diagrammatic scales for the evaluation of black node disease (Stagonosporopsis hortensis and Boeremia spp.) in common bean (Phaseolus vulgaris L.). The developed scales corresponded to logarithmic intervals (SADL) of seven levels and equal intervals (SADE) of nine levels. These scales were compared to the scale developed by the International Center for Tropical Agriculture (CIAT), which corresponds to a descriptive scale (NoSAD). In the scale validation the accuracy, precision, and concordance of repeatability were determined using Lin’s concordance correlation coefficient, whereas inter-rater reproducibility was determined by the overall concordance correlation coefficient (OCCC). It was observed that with the use of the proposed scales, reproducibility and repeatability were significantly improved for inexperienced raters, and reproducibility was improved in the case of experienced raters. Thus, the designed standard area diagrams with equal and logarithmic intervals are a useful tool for estimating severity under field and experimental conditions as part of the study of this patho-system.
