【摘要】 选用48头体重为6 kg左右的"杜长大"三元杂交猪,23±1日龄断奶,根据体重、性别、窝别、日龄相近为原则随机分为3个组,每个组8个重复,每个重复2头猪,分别饲喂空白对照组(基础日粮)、试验组Ⅰ(基础日粮+1%中草药粉剂)、试验组Ⅱ(基础日粮+2%中草药粉剂)三种不同日粮,进行为期4周的饲养试验,考察中草药粉剂不同添加水平对早期断奶仔猪生产性能及抗腹泻的效果。结果显示:(1)与对照组相比,试验期各阶段(前期、后期及全期),1%、2%的中草药不同水平有提高试猪的日增重和日采食的趋势,但与对照组差异不显著(0.10>P>0.05);(2)中草药试验组有较低的腹泻指数,但与对照组差异不显著(P>0.05)。该中草药粉剂在一定程度上改善了断奶仔猪生长性能,并有一定的抗腹泻效果。更多还原

【Abstract】 48 crossed piglets(DxLxY) with the average body weight of 6 kg were allotted into one of three groups to investigate the influence of Chinese herbal powders on production performance and antidiarrheic effect of weaning piglets.The three groups were control group(basal diet),test groupⅠ(basal diet+1% Chinese herbal powders),and test groupⅡ(basal diet+2% Chinese herbal powders).The results showed that:(1) test groupⅠand Ⅱ had higher average daily gain and daily intake(P<0.10) than the control group,but no remarkable differences(P>0.05) were observed;(2) compared with the contro1 group,test groupⅠand Ⅱ had lower diarrhea index,but no remarkable differences were observed(P>0.05).In conclusion,the chinese herbal powders had positive influence on production to some extent and antidiarrheic effect performance of weaning piglets.更多还原
