日粮中添加鱼腥草对生长育肥猪生产性能的影响

Effects of Diets Supplemented with Houttuynia Cordata on the Production Performance of Growing-finishing Pigs

选择体重20 kg左右杜×长×大外三元杂交仔猪40头,随机分为4组,分别为对照组(饲喂基础日粮,不添加鱼腥草)、试验Ⅰ组(基础日粮+0.5%鱼腥草)、试验Ⅱ组(基础日粮+1%鱼腥草)、试验Ⅲ组(基础日粮+1.5%鱼腥草),研究日粮中添加鱼腥草对生长育肥猪日增重及料重比的影响。结果表明,试验Ⅱ组的效果最好,与对照组相比,日增重提高9.23%(P<0.05),料重比降低9.68%(P<0.05)。

Select the weight about 20 kg Duroc （ ♂ ） x Landrace（ ♂ ） x Large White（ ♀） crossbred piglets 40, divided into four groups randomly, respectively, for the control group（ fed with basal diet, do not add Houttuynia cordata）, the test group I（ basal diet ＋ 0.5% Houttuynia cordata）, test group II（ basal diet ＋ 1.0% Houttuynia cordata）, the test group III（ basal diet ＋ 1.5% Houttuynia cordata）, study on the effect of diets supplemented with Houttuynia cordata on average daily gain and feed conversion ratio of growing - finishing pigs. The results show that, the test group II the best, com- pared with the control group, improve the daily gain of 9.23 % （P 〈 0. 05 ）, decreased the ratio of feed conversion 9.68 % （P 〈 0. 05 ）.
