Redução dos níveis de proteína e suplementação aminoacídica em rações para codornas européias (Coturnix coturnix coturnix)

Abstract: O experimento foi realizado objetivando-se avaliar o efeito de nove planos de nutrição (PN) sobre o desempenho de um lote misto de 576 codornas, distribuído em delineamento experimental inteiramente ao acaso, com nove tratamentos e quatro repetições de 16 aves. Nas fases de 1 a 21 dias de idade, os PN foram: PN1 = 28% de proteína bruta (PB), 1,5% lisina (L) e 1,1% de metionina+cistina (MC) de 1 a 21 dias e 24%PB, 1,3%L e 0,9%MC de 22 a 42 dias (controle); PN2 = 25,2% PB, 1,23% L e 0,83% MC de 1 a 21 dias e de … Show more

“…Nevertheless, this practice increases production costs, deviate amino acids for functions not related to growth, worsens environmental conditions, and increases pollution. The use of synthetic amino acids is an interesting alternative to minimize those problems (Silva and Costa, 2009). Therefore, the objective of this study was to evaluate the ratio between digestible methionine + cystine to digestible lysine [d(Met + Cys)/dLys] in the diet for growing Japanese quails.…”

“…Em adição, Silva et al (2006) observam que planos de nutrição para a criação de codornas de corte, em condições brasileiras, ainda não foram desenvolvidos, mas podem ter contribuição importante na redução do custo de produção.…”

“…According to Silva and Costa (2009), the calcium supplementation requirement for Japanese quail from 22 to 42 days of age is 0.50%, while for European quail the requirement is 0.70%, in diets containing 3,050 kcal of metabolizable energy (ME)/kg and 22% crude protein (CP). However, Rostagno et al (2011) recommended 0.90% calcium for Japanese quail in the starter and grower phases, while there was no recommendation reported for vitamin D.…”
