中链功能脂肪对断奶仔猪生长性能的影响
|
摘要
试验旨在研究中链甘油三酯(MCT)对断奶仔猪生长性能的影响。试验采用单因子区组设计,选取100头日龄相近的杜洛克×长白×大白三元杂交断奶仔猪,按体重、性别和窝源均衡原则,随机分成2组,每组5个重复,每个重复10头仔猪。对照组饲喂基础饲料,试验组在基础饲料基础上添加5 kg/t中链甘油三酯(MCT,商品名为优速能)。试验从仔猪断奶当天开始,为期16 d。试验结果表明:与对照组相比,试验组仔猪增重显著提高(P<0.05),仔猪成活率和采食量有所升高,但差异不显著(P>0.05);试验组仔猪腹泻率与腹泻指数均低于对照组。结果提示,断奶仔猪饲料中添加5 kg/t的MCT,可提高仔猪日增重,减少仔猪腹泻,提高仔猪免疫能力。
The effect on growth performance of piglets was studied in weaned piglets fed diets with me-dium chain triglyceride(MCT).According to a single factorial arrangement, a total of 100 weaned pig-lets(Duroc × Landrace × Yorkshire) were assigned to two groups with 5 replicates in each group and10 piglets in each replicate. Control group was fed the basic diet, while the experiment group was fedthe basic diets supplemented with 5 kg/t MCT. The experiment lasted for 16 d. Results showed thatpiglets fed diet supplemented with 5 kg/t MCT had higher weight gain(P<0.05), food intake and sur-vival rate, but tle late two indexes had no significant difference(P>0.05). These results suggest that theeffects of MCT on growth performance of piglets are better that those of control group.
