Proteína Bruta e Proteína Ideal para Frangos de Corte no Período de 1 a 21 Dias de Idade

Abstract: Dois experimentos foram realizados com o objetivo de avaliar o desempenho de frangos de corte no período de 1 a 21 dias alimentados com dietas formuladas nos conceitos de proteína bruta e proteína ideal. No primeiro experimento, foram utilizados 400 pintos machos de um dia de idade da linhagem Cobb, distribuídos em delineamento inteiramente casualizado, com 2 tratamentos (proteína total e proteína ideal) e 5 repetições de 40 aves cada. No segundo experimento, foram utilizados 800 pintos, 400 machos e 400 fêmea… Show more

“…In a previous study, Araújo (2001) evaluated the performance and carcass yield of broilers fed diets formulated on total or digestible amino acid basis during the periods of 22 to 42 days and 43 to 49 days of age and observed better performance, as well as carcass and breast yields in broilers fed diets formulated with digestible amino acids during the grower and finisher phases, respectively.…”

“…However, warns for the performance loss caused by intense decreases, even when there is supplementation with industrial amino acid. Araújo et al (2001) working with the objective of evaluating broilers performance fed on formulated diets based on crude protein or ideal protein found that ideal protein resulted in better weight gains, increased feed intake and no effect on feed conversion. In contrast, Hussein et al (2001) NRC, 1994).…”

“…A expressão gênica, os efeitos ambientais e sanitários somente exercem uma importância primária sobre o desempenho animal caso as exigências nutricionais sejam devidamente alcançadas. No entanto, o fornecimento excessivo de nutrientes pode, ainda, ser mais dispendiosa que as deficiências, porque chega a limitar a produção e, concomitantemente, pode incrementar o custo de produção (ARAÚJO et al, 2001).…”
