摘 要：
研究在断奶仔猪日粮中添加0.5%的超微粉碎中草药饲料添加剂对断奶仔猪生长性能和腹泻率的影响。试验采用单因素完全随机试验设计,选取平均体重为(9.50±0.63)kg的28日龄断奶的健康仔猪54头,随机分为3个处理组,每个处理组中包含3个重复,即每个处理有18头断奶仔猪,每个重复6头,公母各半,经统计分析,各处理间体重差异不显著(P>0.05)。试验设1个对照组和2个试验组,具体处理如下:对照组饲喂基础日粮(不含有抗生素等药物),试验Ⅰ组为基础日粮+0.02%黏杆菌素,试验Ⅱ组为基础日粮+0.5%超微粉碎中草药饲料添加剂。饲养期30 d。结果表明,试验Ⅱ组的平均日采食量和日增重均显著高于对照组(P<0.05),而试验Ⅱ组的料肉比和腹泻率均显著低于对照组(P<0.05),并且试验Ⅱ组的饲喂效果要优于试验Ⅰ组。因此,在该试验条件下,用超微粉碎中草药饲料添加剂替代抗生素添加到断奶仔猪日粮中,能够保证断奶仔猪的健康生长。

摘 要：
The aim of the study was to investigate the effects of ultra-fine herbal feed additive at a proportion of 0.5% on growth performance and diarrhea rate in weaned piglets.Single factor completely randomized design was used for the experiment.A total of 54 healthy weaned piglets [(9.50 ± 0.63) kg,28 days old] were selected and randomly divided into three treatment groups including two experimental groups and one control group,18 in each group(half male and half female) and three replicates in each group.Statistical analysis showed no significant difference in body weight between the groups(P>0.05).The piglets in the control group were fed basic diet not containing any drug like antibiotic.Those in the group Ⅰ were fed with the basic diet supplemented colistin at a dosage of 0.02%.Those in the group Ⅱ were fed with the basic diet supplemented ultra-fine herbal feed additive at a proportion of 0.5%.The feeding period was 30 d.The results showed that the average daily feed intake and daily gain of the group Ⅱ were significantly higher than that of the control group(P<0.05).The feed conversion rate and diarrhea rate of the group Ⅱ were significantly lower than that of the control group(P<0.05).And the feeding effects were better in the group Ⅱ than in the group Ⅰ.Therefore,in the experimental conditions,the ultra-fine herbal feed additive,an alternative of antibiotic feed additive,can ensure the healthy growth of weaned piglets.
