摘要
为研究不同种类抗菌肽对断奶仔猪生产性能及腹泻的影响,选用33日龄、平均体重(9.23±0.71)kg的断奶仔猪90头,公母各半,随机分配到3个处理组,每个处理3个重复,每个重复10头猪。分别饲喂各处理组饲粮:对照组为基础饲粮、处理1组为基础饲粮添加A型抗菌肽0.04%、处理2组为基础饲粮添加B型抗菌肽0.05%,试验期为17d。结果表明,与对照组相比,各抗菌肽处理组仔猪平均日增重、平均日采食量、料肉比均存在显著差异(P<0.05);粗蛋白质表观消化率差异不显著(P>0.05),仔猪腹泻指数均显著降低(P<0.05)。因此,抗菌肽可改善断奶仔猪生长性能,降低腹泻率。
To study effects of adding different kinds of antibacterial peptide on production performance and di-arrhea of weanling piglets, ninty weanling piglets of thirty-three days old about 9.23 kg body weight were selected according to their weight and sex, and randomly divided into three groups for three replicates of ten pigs each. The control group were feeding basical fodder, group 1 were supplemented 0.04% type A antibacterial peptide in basical fodder, group 2 were supplemented 0.05% type B antibacterial peptide in basical fodder. The experiment lasted for seventeen days. The results showed that, compared with the control group, the piglet of treatment groups ADG, AD-FI, FCR had significantly（P〈0.05）. Protein apparent digestion rate had no significant differences（P〉0.05）. Diarrhea rate decreased significantly（P〈0.05）. The result showed that basical fodder adding antibacterial peptide can improve piglet production performance, decrease diarrhea rate.
