发布时间:2018-08-17 11:56
【摘要】:为了探讨复合微生态制剂对藏香猪育肥增重的影响,试验选择60日龄断奶、体重(12.71±0.33)kg藏香猪断奶仔猪90头,随机分为3组,每组30头。1组饲喂基础日粮+0.1%复合微生态制剂,2组饲喂基础日粮+抗生素,3组饲喂基础日粮。试验期120 d。结果表明:藏香猪3,4月龄体重1组显著高于2,3组(P0.05);5月龄体重1组2组3组(P0.05);6月龄体重1组3组2组(P0.05);藏香猪2~≤3月龄的日增重1组显著高于2组、3组(P0.05);3~≤4月龄、4~≤5月龄的日增重各组间无显著差异(P0.05);总采食量、平均日采食量、平均日增重、料重比均为1组3组2组。说明在本试验条件下,藏香猪2,3,4月龄时在基础日粮中添加0.1%复合微生态制剂可促进其生长发育,提高日增重,降低料重比,且效果优于抗生素。
[Abstract]:In order to study the effect of compound microecological preparation on weight gain of Tibetan Xiang pigs, 90 weaned piglets with body weight of (12.71 卤0.33) kg were randomly divided into 3 groups. Each group of 30 head .1 group was fed with basal diet 0.1% compound microecological agent and group 2 was fed with base diet antibiotic group 3 groups were fed basic diet. The experiment period was 120 days. The results showed that the weight gain of Tibetan Xiang pigs in group 1 was significantly higher than that in group 2 (P0.05) and that in group 1 was significantly higher than that in group 2 (P0.05). There was no significant difference in daily gain between groups of 4 ~ 鈮,
