龙须眼子菜在生长育肥猪日粮中的应用研究

为了确定在生长育肥猪日粮中添加龙须眼子菜（水草）对生长育肥猪生产性能的影响，试验选取40头健康白猪．公母比为1：1，体重30kg左右，共分为4组，每组10头，分别饲喂含不同水平水草的日粮，用水草代替部分麸皮，水草的添加量分别为0％、3％、7％、11％。预试期为7d。正试期为三个阶段：前期、中期、后期。试验结果显示：添加不同水平的水草．对生长育肥猪的日增重没有显著影响；在猪日粮中添加3％的水草。可提高日粮养分的消化率。

Application of Potamogeton Pectinatus L.in Growing and Fattening Pigs Dietary

Inorder to determine the effect of the adding of Potamogeton Pectinatus to the diet of pig starter on production,40 healthy white pigs were selected in this experiment ,half of which were boar pigs and the other sows, their avoirdupois were about 30kg,they were randomly divided into four groups and each group included 10 pigs. During trial periods,pigs of each group were fed with the adding of 0% ,3% ,7% ,11% Potamogeton Pectinatus respectively.Comparing with the parallel group,there was no significant （P〉0.05） difference in daily gain of the control groups ;the adding of 3% Potamogeton Pectinatus can enhance the digestion rate of nutrients in the diet.
