按不同氨基酸模式配制肉鸭日粮的比较研究

Comparative Study on Diets of Meat Duck Formulated With Different Amino Acid Patterns

试验比较了不同氨基酸模式对肉鸭生产性能的影响。将320只1日龄的樱桃谷鸭随机分为4组,每组80只,设4个重复,每个重复20只,公母各半,分别饲喂四种日粮(按四种氨基酸模式配制),试验期21天。结果表明:日粮的氨基酸模式为Lys∶Met∶Trp∶Thr=100∶45∶21∶62时,其2周和3周体重高于其它各组,但差异不显著(P>0.05),且F/G和血清尿酸水平最低。

Effects of different amino acid patterns on meat ducks performance were compared in the experiment.In a 21-day study,320 one-day-old cherry valley meat ducks were randomly assigned to four groups,4 replicates in each group and 20 birds per replicate(10 male and 10 female).These birds were fed on four kinds of diets formulated with four amino acid patterns, respectively.The results showed body weights or ADG (aged 2 w and 3 w)of the group fed with amino acid pattern Lys:Met:Trp:Thr =100:45:21:62,were higher than other groups,but difference was not significant(P>0.05).The feed conversion rate of this group was also higher and the content of uric acid was lower than other groups.
