Effect of Ideal Amino Acid Profile and Week-Feeding on Production Performance in Broilers

Ideal amino acid profile, BAHA and BAHA week-feeding (WF) were tested to evaluate their efficacy compared with NRC 1994 recommendation for broiler chicks. 13 kinds of diets were fed from (0~49) days to 192 broiler chicks. All chicks were allotted to three treatments in a completely randomized design, every treatment had replicates (8 chicks per pen). The results were: Fed ideal amino acid profile diets for broilers, lower the diet's protein 1.45% in 1~3week, 1.39% in (4~6) week, there were no differences (p0.05) in weight, weight gain, feed intake and feed efficiency to NRC diets. Fed ideal amino acid profile WF diets, lower the protein 2.61% in 3th week, 2.41% in 6th week, there were no differences (p0.05) in weight, weight gain, feed intake and feed efficiency to NRC diets. These results indicated that WF supported maximum growth performance during the protein levels were reduced period. Economic analysis indicated that BAHA and BAHA PF would reduce the cost per unit weight gain without sacrificing growth performance. For the blood sugar in artery and vein of broilers, BAHA and WF might increase its content (p0.05).
