摘要
选取28日龄体质量相近的杜长大断奶仔猪72头,随机分成4个组,每组3个重复,每个重复6头,各重复公母猪各半进行28 d的饲养试验,试验共设对照组(基础日粮)、中药I组(基础日粮+1%中药配方I)、中药II组(基础日粮+1%中药配方II)、抗生素组(基础日粮+抗生素)4个处理,研究中药添加剂对断奶仔猪生产性能和腹泻率的影响。结果表明,饲粮中添加中药和抗生素提高了断奶仔猪的平均日增质量(ADG)(P>0.05),中药II组和中药I组显著改善了料肉比(P<0.05),抗生素组也有不同程度的改善(P>0.05);各试验组显著减小了仔猪腹泻的持续时间和腹泻频率(P<0.05),中药II组极显著降低了腹泻频率(P<0.01),显著降低了腹泻指数(P<0.05),而抗生素组和中药I组的腹泻指数与对照组相比无显著差异(P>0.05)。
Seventy-two 28 day old Duroc × Landrace-Yorkshire weaned piglets were assigned randomly into four groups. Four treatments were： control group, Chinese medicine group Ⅰ, Chinese medicine group Ⅱ and antibiotic group. The results were as follows： Average daily gain （ADG） was increased in Chinese medicine groups and antibiotic group （P 〉 0.05 ）. Feed conversion rate was improved remarkably in Chinese medicine group Ⅱ and in Chinese medicine group I （P 〈 0.05 ）, and increased in various degrees in the antibiotic group. Each group reduced the persistent duration time of diarrhea and the diarrhea frequency （P 〈 0.05 ） obviously. Diarrhea index and diarrhea frequency were reduced significantly in Chinese medicine group II （P 〈 0.01 ）. While the diarrhea index of antibiotic group was significantly lower than the control group （P 〈 0.05 ）, but showed no significant difference with Chinese medicine group I （P〉 0.05 ）.
