摘要
为探讨添加不同剂量中草药和抗生素对仔猪生产性能与经济效益的影响,本试验选择60头健康的三元杂交断奶仔猪(杜×长×大),体重为(10±1)kg,随机分成4个试验组,分别为试验1、2、3、4组(3个试验组和1个对照组),每个试验组设3个重复,每个重复选5头仔猪,在各试验组基础日粮中分别添加0.2%、0.4%中草药和抗生素(400mg/kg硫酸黏杆菌素)。试验结果表明,添加0.2%、0.4%中草药组和添加抗生素组比对照组平均日增重分别提高了8.24%、9.17%和8.65%,均差异显著(P<0.05);料重比分别下降了5.12%、6.56%和5.01%,均差异显著(P<0.05);仔猪腹泻率明显下降;头均毛利分别提高了3.78%、5.87%和4.07%。结果表明该中草药组方在一定程度上可完全替代抗生素,且添加不同剂量中草药的饲喂效果存在一定差异。
In order to study the effects of different doses of Chinese herbal medicine and antibiotics on production performance and economic benefits of weaning piglets, 60 three crossbred healthy weaning piglets were selected （Duroc× Landrace × Large White）, with the weight of （10±1）kg. They were randomly divided into 4 treatment groups （3 experimental groups and 1 control group） and each group had 3 replications including 5 piglets separately. In each experimental group, the basal diets were supplemented with 0.2%, 0.4% Chinese herbal medicine and antibiotics （400 mg/kg of colistin sulfate）. The results showed that, in comparison to the control group, the average daily gains in 3 experimental groups increased respectively by 8. 24%, 9.17% and 8.65% in turn, significant differences （P〈0.05） ; feed to gain ratioes were decreased by 5.12%, 6.56% and 5.01%, significant differences （P〈0.05） ; piglet diarrhea rates decreased; the gross profits per pig increased respectively by 3.78%,5.87 % and 4.07%. It illustrated that Chinese herbal medicine could completely replace antibiotics to a certain extent, but there were some differences between the effects of different doses of Chinese herbal medicine.
