37. Genetic evolution of milk yield, udder morphology and behavior in Gir dairy cattle
ABSTRACT The objective of this study was to analyze the genetic evolution of milk production, udder morphology, and animal behavior of Gir dairy cattle. Data were obtained on the predicted breeding values for milk yield of 60,226 cows born from 1968 to 2015 and standardized predicted breeding values for udder conformation and milking behavior of 7,635 cows b

38. The potential of plant and fungal proteins in the control of gastrointestinal nematodes from animals
Resumo A infecção por nematoides gastrintestinais é uma importante causa de grandes perdas econômicas na pecuária. O controle de nematoides com compostos químicos sintéticos é considerado insustentável devido ao aumento da resistência anti-helmíntica. Alternativas de controle, como o uso de produtos naturais, estão se tornando relevantes do ponto

39. Carcass characteristics and fatty acid profile of Santa Inês lamb fed banana leftovers
ABSTRACT: The use of new feed resources, particularly local agroindustrial byproducts, such as banana, may be an option for replacing those traditionally used for sheep feed to reduce production costs. Thus, the aim of this study was to evaluate the dietary effects of replacing corn bran with banana leftovers on performance, carcass, non-carcass components,

40. Análise bioeconômica de períodos de suplementação proteico-energética na estação seca para novilhas Nelore em pastagem diferida de Urochloa decumbens
RESUMO A suplementação proteico-energética (SPE) é uma estratégia adequada à bovinocultura de corte no período seco do ano, embora sua adoção equivocada possa comprometer seu benefício/custo. O objetivo deste estudo foi avaliar o desempenho de novilhas Nelore em pastagem diferida de Urochloa decumbens sob dois períodos de SPE, e realizar análise

41. Suplementação proteica de vacas leiteiras mantidas em pastagem de Tifton 85 durante o período de seca
RESUMO Concentrados com alta proteína bruta e minerais e com menor concentração de energia poderiam ser utilizados em menores quantidades no balanceamento de dietas com volumosos tropicais. Assim, objetivou-se avaliar o consumo de matéria seca, a resposta produtiva e econômica de vacas da raça Girolando mantidas em pastagem de Tifton 85 durante o perí

42. Morpho-physiology, yield, and water-use efficiency of Opuntia ficus-indica irrigated with saline water
ABSTRACT. Forage cactus pear is considered a xerophilic plant, so it is adapted to harsh semiarid conditions and is a forage resource of significant importance for animal production in regions that are subject to food shortage and long dry periods. We aimed to evaluate the morphometric and physiologic characteristics and water-use efficiency of ‘Gigante’

43. A Meta-Analysis of the Impact of Foliar Feeding of Micronutrients on Productivity and Revenue Generation of Forage Crops
RESUMO: A garantia de segurança alimentar frente ao aumento da população exige incremento proporcional da produção de leite e carne, que por sua vez depende da nutrição animal. Avaliar a adubação foliar com micronutrientes para produção de quantidades substanciais de forragem de boa qualidade deve ser um objetivo da agricultura moderna, com fins l

44. Determination of methanol residues in crude glycerol for animal feed by gas chromatography
ABSTRACT: Crude glycerol is a major by-product of biodiesel production and is an economical additive feed for ruminants. However, residual methanol in crude glycerol can be harmful to animal health. Several methods exist for quantifying methanol residues in biodiesel, yet few have been described that identify the methanol level in crude glycerol. We propose

45. Impacts of food-based enrichment on behaviour and physiology of male greater rheas (Rhea Americana, Rheidae, Aves)
Abstract Distress can be defined as a biological response of an individual to long-term threats to its homeostasis and it should be avoided from an animal welfare perspective. High levels of stress hormones and the expression of abnormal behaviours are responses normally observed in distressed animals. Captive environments can provoke distress, especially wh

46. Productivity and nutritive value of elephant grass pastures under organic and conventional production systems
Abstract: Elephant grass (EG) (Pennisetum purpureum Schum.) have great importance in tropical and subtropical climates, especially on dairy farms. Normally, EG is established alone under high fertilization levels. EG in organic production system can improve low production costs and environmental issues, are still little known. The aim of this research was to

47. Duplex Real-Time PCR Using Sybr Green I for Quantification and Differential Diagnosis between Salmonella Enteritidis and Salmonella Typhimurium
ABSTRACT The incidence of foodborne diseases caused by the genus Salmonella spp. in industrialized countries is often high in epidemiological surveys. Obtaining a rapid diagnostic test for identification of bacteria is crucial in order to rapidly implement control measures to contain bacterial spread, to reduce losses in animal production and to avoid risks

48. Epigallocatechin Gallate (EGCG) Inhibited the Alv-J-Induced Apoptosis in Df-1 Cells by Inactivation of Nuclear Factor κb Pathway
ABSTRACT Avian leukosis virus subgroup J (ALV-J), a member of the retroviridae family, can infect both broilers and layers and induce a spectrum of different neoplasms, resulting in serious economic losses in poultry production. Epigallocatechin-3-gallate (EGCG), the major constituent of green tea, has demonstrated remarkable anti-inflammatory and cancer che
