37. Effects of dietary lysine on broiler performance and carcass yield - meta-analysis
There has been a great evolution and improvement in the nutrition of poultry and lysine has been used the reference amino acid to increase animal protein deposition. Therefore, a meta-analysis was performed with the objective of studying the effect of different dietary lysine levels on the performance and carcass yield of broiler chickens. In total, 21 studi

38. Feeding strategies to design the fatty acid profile of sheep milk and cheese
The majority of sheep milk produced in the world is transformed into cheese. Feeding is a major factor affecting the quality of sheep milk and, therefore, of sheep cheese. Because fat is the main compound of cheese, this review gives an update on the effects of feeding and nutrition on milk fat content and deeply discusses feeding strategies aimed at increas

39. Growth of Nile tilapia post-larvae from broodstock fed diet with different levels of digestible protein and digestible energy
This study was carried out to evaluate the influence of different levels of digestible energy and digestible protein in diets of Nile tilapia (Oreochromis niloticus) broodstock on offspring growth during sex reversal stage. A total of 2,700 post-larvae (8.2±0.001 mg) derived from breeders fed nine diets with distinct levels of digestible protein (28, 34 and

40. Programa de intervenção interdisciplinar em hábitos de vida em indivíduos de risco cardiometabólico: análise de fatores dietéticos associados à melhora do metabolismo glicídico / Interdisciplinary intervention program on lifestyle in individuals at cardiometabolic risk: analysis of dietary factors associated with improvement in glucose metabolism
Introduction: Cardiometabolic diseases are global public health problems with social and economic repercussions. Unhealthy diet is seen as one of the main modifiable risk factors, being of central importance for the prevention of these diseases. Despite the evidence that certain nutrients are associated with diseases, causal relationships are still under dis

41. Pró-dieta: gerador automático de cardápios personalizados baseado em algoritmos genéticos
O uso de sistemas computacionais e técnicas de Inteligência Artificial (IA) para resolver problemas do mundo real está cada vez mais frequente e, na área nutricional, não é diferente. No Brasil e no mundo, os sistemas mais encontrados são os de auxílio à prescrição de cardápios e formulação de dietas. Este trabalho apresenta uma metodologia de

42. Avaliação do potencial genotóxico do 51Cr2O3, marcador de digestibilidade, por meio da frequência de anormalidades nucleares em tilápias do Nilo (Oreochromis niloticus L.) / The evaluation of genotoxic potential of 51Cr2O3, a digestibility marker, by the frequency of nuclear abnormalities in Nile tilapia (Oreochromis niloticus L.)
Tilapia is the common name of a large number of species of cichlid fish. In aquaculture, this is one of the most profitable fish, since it presents lower feed conversion than other fish. The chromium oxide has been used as a marker for digestibility because it is inert and not alter the biological process of dietary intake. The use of radioactive form of chr

43. Effect of tanniniferous plants and essential oils on methane emission in ruminants / Efeito de plantas taniníferas e óleos essenciais sobre a emissão de metano em ruminantes
Tannins and essential oils are secondary metabolites that may be used as natural modifiers of rumen fermentation to reduce the ruminants\ methane (CH4) emission. To study the application of tannin-rich plants from Egypt and Brazil, as well as essential oils that are available in international trade, three studies were conducted at Animal Nutrition Laboratory

44. Efeitos da adição de complexo multienzimático sobre o desempenho de frangos de corte / Effects of adding multienzyme complex on the performance of broilers
Two experiments were conducted at the Department of Animal Science, University of São Paulo (USP), College of Animal Science and Food Engineering (FZEA) in Pirassununga / SP, with the aim of studying the performance of broilers fed diets supplemented with exogenous enzymes. The experimental diets consisted of corn, soybean meal, vitamins, minerals and exoge

46. PROCESSING WASTE OF JUNDIÁ (Rhamdia quelen) AND ITS NUTRITIONAL VALUE IN FISH DIETS / RESÍDUOS DE PROCESSAMENTO DE JUNDIÁ (Rhamdia quelen) E SEU VALOR NUTRICIONAL EM DIETAS PARA PEIXES
The aim of this study was to evaluate the use of processing waste and discard of jundiá used in the diet of this species, verifying its influence on growth, serum biochemistry, liver and digestive parameters. In the first experiment, 50 fish per experimental unit were used (initial weight = 5.53 0.09 g). Four diets were tested: control, composed of 30% swin

47. FONTES DE CARBOIDRATOS PARA TERMINAÇÃO DE BOVINOS DE CORTE: DESEMPENHO E CARACTERÍSTICAS DA CARCAÇA E DA CARNE / SOURCES OF CARBOHYDRATES FOR STEERS FINISHING: PERFORMANCE AND CARCASS CHARACTERISTICS AND MEAT
The objective of this study was to evaluate the effect of three carbohydrate sources (corn, soybean hulls or wheat bran) in the diet on performance, carcass characteristics and meat and the components are not part of the carcass of steers finished on confinement. We used 24 steers, crossbred Charolais x Nellore, with initial age of 22 months of initial body

48. Characteristics of a β-1,4-D endoglucanase from Trichoderma virens wholly applied in a palm-fruit husk-based diet for poultry layers
The characteristics of an endoglucanase produced by a Trichoderma virens strain T9 newly isolated from a palm-fruit husk dump site, its physiological characteristics and enzyme production were studied. Whole cells of the depolymerizing-enzyme producing T. virens were applied to palm-fruit husk and bird performance characteristics when employed as poultry die
