Desenvolvimento do sistema digestório e da capacidade digestiva de frangos de c...
Fagundes, Naiara SimarroThe objective of this study was to evaluate the effect of diets with different metabolizable energy levels on the development of the digestive system and digestive capacity of broilers. This experiment employed a 4x9 factorial design (metabolizable energy levels: low, medium, high and very high; x age: every three days until 28 days old). Four birds from each treatment were euthanized and had body weight, relat...
Effect of nutrition on the body temperature and relative organ weights of broilers
Martins, Julyana Machado da Silva; Fernandes, Evandro de Abreu; Bueno, João Paulo Rodrigues; Carvalho, Carolina Magalhães Caires; Litz, Fernanda HeloisaThe objective of this study was to evaluate the effect of different nutritional plans on the body temperature and organ biometrics in male and female broilers, of two ages. Here, 1,700 birds were used (850 males and 850 females) in a completely randomized design composed of five treatments (- 3%, - 1.5%, reference, + 1.5% and + 3%), with 10 repetitions, totaling 50 experimental units; the reference treatment ba...

Carolino, Andressa Cristina Xavier Gomes; Silva, Marina Cruvinel Assunção; Litz, Fernanda Heloisa; Fagundes, Naiara Simarro; Fernandes, Evandro de AbreuAvaliou-se o efeito do sorgo inteiro em comparação ao milho sobre o rendimento de carcaça, rendimento de cortes comerciais e a composição química da carcaça de frangos machos e fêmeas aos 42 dias de idade. Foram utilizados 960 frangos da linhagem Hubbard Flex. O experimento foi conduzido num delineamento inteiramente casualizado com esquema fatorial 3 x 2, sendo 3 rações - milho grão moído (Mm), sorgo grão inte...

Carvalho, Letícia Souza Silva; Machado, Camila Alves; Fagundes, Naiara Simarro; Litz, Fernanda Heloisa; Fernandes, Evandro de AbreuThe objective of this study was to evaluate the effects of fasting time on biometrics organ digestive tract and performance of broilers. A total of 640 sexed birds were, distributed according to a completely randomized design with four periods of fasting after hatching (0, 12, 24 and 36 hours) and four replicates of 40 birds each (20 females and 20 males). The evaluation of body weight and biometrics of the org...
