纤维素复合酶对肉鸡屠宰性能和肉质性状的影响

选用1日龄AA肉鸡128羽,随机分成4组,每组4个重复,对照组饲喂基础日粮,试验组在基础日粮中添加0.05%、0.1%和0.15%的纤维素复合酶,研究添加不同水平纤维素复合酶对肉鸡屠宰性能和肉质性状的影响。结果表明,添加纤维素复合酶可显著提高肉鸡宰前活重、屠体重、半净膛重、全净膛重和胸肌重、全净膛率、半净膛率和胸肌率(P0.05),降低腹脂重和腹脂率(P0.05);改善肉鸡肌肉品质,显著降低了胸肌和腿肌的失水率(P0.05);显著提高肝脏重和肝脏指数(P0.05)。

Effects of cellulose complex enzyme on slaughter performance and meat quality of broiler

One hundred and twenty eight 1-day-old AA broiler chickens were randomly allocated to four groups for 4 replicates,and fed a commercial starter diet and the same diets supplemented with 0.05 %,0.1 %,and 0.15 % of cellulase to study the effects of different levels of supplementary cellulase on the growth performance,carcass quality and organ indexes of broilers.The results showed that the body weight,dressed weight and its rate,half-eviscerated weight and its rate,eviscerated weight and its rate,breast muscl...
