摘要
探讨多花黑麦草在猪日粮中的等量替代比例,将40头体重24kg左右的＂杜×长×大＂三元杂交仔猪随机分为4组,即对照组饲喂基础日粮,试验Ⅰ-Ⅲ组分别在基础日粮中添加10%、20%和30%的多花黑麦草,观察其对生长育肥猪的生产性能及效益影响。结果表明：试验Ⅰ、Ⅱ组平均日增重比对照组分别提高6.33%（P〈0.05）、0.40%（P〉0.05）,试验Ⅲ组比对照组降低3.71%（P〉0.05）。料重比,试验Ⅲ组比对照组及试验Ⅰ、Ⅱ组分别降低25.57%（P〈0.01）、11.91%（P〈0.05）、7.50%（P〉0.05）,试验Ⅱ组比对照组、试验Ⅰ组分别降低19.54%（P〈0.01）、4.76%（P〉0.05）,试验Ⅰ组比对照组降低15.51%（P〈0.05）。毛利润比对照组分别提高29.17%、24.94%和22.26%。以添加10%的多花黑麦草效果较好。
In order to probe into the substitute proportion of Italian ryegrass in pig＇s diet,forty three-way crossbreeding pigs of＇Duroc×Large white×Landrace＇which weighed about 24 kg were randomly divided into four groups.In the control group,pigs were fed with the basic diets,in groupⅠ,groupⅡand groupⅢ,10%,20%and 30%Italian ryegrass were added to the basic diets,respectively,and the productive performances of pigs,benefit and influence were observed.The results showed that：compared to the control group,in experimental group Ⅰ and group Ⅱ,the daily gain of pigs increased by 6.33%（P〈0.05）and 0.40%（P〈0.05）,respectively,but in group Ⅲ,the daily gain of pigs reduced by 3.71%（P〈0.05）.Compared with the control group,groupⅠ,groupⅡ,the feed conversion ratios in groupⅢ decreased by 25.57%（P〈0.01）,11.91%（P〈0.05）,and 7.50%（P〈0.05）,respectively;compared with the control group,group Ⅰ,the feed conversion ratios in groupⅡ decreased by 19.54%（P〈0.01）and 4.76%（P〈0.05）,respectively.gross profits of the three experimental groups raised by 29.17%,24.94% and 22.26%.The effect of adding 10% of Italian ryegrass was better.
