摘要
选用60头体重约60kg左右的三元杂交(杜×长×大)商品代瘦肉型肥育猪,随机分为试验组和对照组两组,每组又设三个重复,每个重复10头猪。试验组饲喂添加200g/吨半胱胺含量为50%的“大丰收”(由杭州某饲料有限公司提供)的日粮,对照组日粮不添加大丰收。进行为期41天的对比试验。试验结果显示:同对照组相比试验组平均日增重、饲料转化效率、瘦肉率和胴体品质均得到不同程度的提高和改善;而且在外观上也得到明显的改善;猪后臀丰满、皮红毛亮、肌肉发达。
three-way cross-bred Duroc X(Landrace X Yorshine)lean meat finishing pigs were used to evalute the effects of feeding Cystimine.Initial average weight of finishing pigs is60kg(P>0.05).The finishing pigs were randomly allocated to2treatment s with3replication(10finishing pigs for each replication),The east trealment feed diet appending100g Cystimine (supplied by Hangzhou Kangdequan Feed Co.,Ltd).At day41,The result showed that average daily gain?feed efficiency?lean tissue growth rate and carcass quality of the treatment feeding Cystimine were increased and amended.
