Investigation on the availability of amino acids from different animal protein sources in golden cockerels

摘要: The direct relationship exists between the quality of an animal protein source and its available amino acids. A number samples each fish meal, feather meat meal blood were analyzed for their proximate composition. Then two ingredient one having highest (grade A) other with lowest crude B) selected. They average availability fifteen acids in high grade 85.68, 80.36, 85.53 77.62 percent, respectively. Whereas low 78.12, 76.60, 67.10 69.46 All sources force fed to birds excreta collected during trial. Feed acid. acid contents a feed assayed by measuring live weight gain, conversion efficiency, nitrogen retention chicks given intact as supplement diet deficient particular under investigation. It was clear after determination that more are compared source. Thus it concluded ingredients impose effect on profile.
