Determination the effects of total and digestible amino acid on performance of Arian broiler chickens

A study was conducted to evaluate application of digestible or total amino acid formulation of diet for broiler chickens. Diet was formulated using total or digestible amino acid as requirement or feed ingredient as suggested by Aryan broiler chick recommitted on 0-21 and 22-42 days. This experiment was in order to using 400 broilers chicks.The experiment was carried out using a complete randomize design as a factorial arrangement (2×2) with 5 replicated (20 chicks per each replication).result showed that digestible amino acid contents of feed stuffs compare to true digestible amino acid performance of birds as feed intake body weight and FCR (p<0/05). However performance data obtained of broiler chicks demonstrate the advantage of feed formulation based on digestible amino acid in feed ingredients compare to digestible amino acid requirement of birds.The results obtained in the present study suggest that diet formulation based on digestible amino acid ingredients and total amino acid requirement of bird.
