| 摘 要： | 本试验用长×(杜×哈)杂种猪12头,随机分为3组。在总采食量相等的前提下,每组接受一种处理:日采食量均等分配直线增加(一组);前50天1组的70%给食,后50天均等增加至总量(2组);3组与2组正相反。试验由活重40kg开始至处理100天结束,并全部屠宰测定。a.生长期轻度限食,日增重降低,但后期表现出明显的补偿作用。最终体重大,全期日增重高。b.育肥期限食可得到较瘦的胴体,背膘较薄。c.后期限食使肝、肾和消化道总鲜重降低。

| Abstract: | Twelve Landracex (Duroox Harbin White) 40kg growing pigs were randomly allo-cated to three groups of three treatmeatments:daily feed intake increased linearly in groupone;pigs in group two were fed 70% intake of group one during the first 50 days and subse-quently fed ad lib itum in the next 50 days;group three was vice versa to group two.All ani-mals were fed the same amount of feed.a.feed restriction during the growing period reduced average daily gain.Restricted ani-mals showed significant compensatory gain when changed to ad libitum feeding.Restrictedly-fed pigs and th best live weight and ADG.b.Feed.restriction in the finishing period produced more preferable carcass and backfatthickness nad reduced the liver,kidney and alimentary tract fresh weights. |
