Determining biological effects of functional amino acid supplementation in low crude protein diet on growth performance of layer chicken
This investigation sought to determine the biological effects of functional amino acids on the growth performance of layer chickens. A total of 144 Hisex Brown hens were allocated into 4 groups that were each fed low crude protein diet from 16 to 32 weeks of age. Diets contained 17.5% CP (control gr...

| description | This investigation sought to determine the biological effects of functional amino acids on the growth performance of layer chickens. A total of 144 Hisex Brown hens were allocated into 4 groups that were each fed low crude protein diet from 16 to 32 weeks of age. Diets contained 17.5% CP (control group), 17.5% CP, 17% CP and 16.5% CP and were supplemented with limiting AA (methionine, lysine and threonine). Weekly feed intake, egg weight, hen-day egg production and feed conversion ratio (FCR) were collected. There was no significant difference (P>0.05) among the treatment groups on overall feed intake, egg weight and egg mass. Significant higher (P<0.05) overall hen-day egg production was observed in all treatment groups compared with the control. Overall, 17.5% CP diets resulted in better egg production than other treatments. |
