摘要
依据扣除法原理,根据现有氨基酸需要量标准和目前的研究结果规划出一种氨基酸模式,依次将模式中赖氨酸、蛋氨酸、色氨酸、苏氨酸、异亮氨酸扣除20%,而非扣除的氨基酸量保持不变,来确定扣除某一种氨基酸后对育雏期北京鸭生产性能和血液生化指标的影响,确定出理想的氨基酸比例。试验共设 6 个处理组,为 6 种氨基酸模式,每个处理设4个重复。结果表明:北京鸭育雏期氨基酸理想模式为赖氨酸∶蛋氨酸∶色氨酸∶苏氨酸∶异亮氨酸=100∶42∶22∶38∶48。
The experiment was conducted based on the method of the deletion to investigate the ideal pattern of dietary Lys,Met,Trp,Thr,Ile in 0~3 week-age Beijing ducks. When 20% of a single amino acid was removed from the amino acid pattern was regulated based upon the standards of nutrition requirement and the results of the recent research, others were not modified .Ducks were randomly allotted to six treatments and fed a basal corn-starch-peanut meal diet containing 15.93%CP,12.74MJ/kg ME, 0.46% Lys,0.19% Met,0.12% Trp,0.42% Thr and 0.42% Ile. The results indicated that the ideal amino acid pattern in 0~3 week-age Beijing ducks was Lys100, Met 42,Trp 22,Thr 38,Ile 48.
