Effect of dietary cereal type, crude protein and butyrate supplementation on metabolic parameters of broilers.

摘要: This study investigates the metabolic effects of maize- or wheat-based diets with normal (NP) and lowered (LP) dietary crude protein level [the latter supplemented limiting amino acids sodium (n-)butyrate at 1.5 g/kg diet] different phases broiler fattening. Blood samples Ross 308 broilers were tested age 1, 3 6 weeks. Total (TP) concentration increased in decreased LP groups week 3, while butyrate reduced albumin/TP ratio 1. Uric acid was elevated by diet 1 but weeks 6. Aspartate aminotransferase activity creatine kinase intensified glucose 3; however, triglyceride augmented same 3. No change glucagon-like peptide glucose-dependent insulinotropic polypeptide insulin observed. In conclusion, an age-dependent responsiveness to factors found, cereal type a potent modulator metabolism, low might have beneficial impact on growth chickens.
