摘要
本试验选取体重相近的育肥猪280头,随机均分成7个组(6个试验组和1个对照组),在试验组猪日粮中分别添加1.0%、1.5%、2.0%、2.5%、3.0%、3.5%的复方中草药添加剂,每个月饲喂一次,一次连续一周,直到160日龄左右称重结束,对照组不添加。结果显示:试验组的末重、日增重指标均优于对照组,差异极显著(P<0.01);试验组的料重比优于对照组,料重比下降了0.10～0.30。综合末重、日增重、料重比、发病数及生产成本等因素,中草药添加剂以2.0%的添加比例为最优。
280 fattening pigs which were similar weight were assigned seven groups(six treatment groups and one control group) randomly, pigs in treatment group were fed with 1%, 1.5%, 2%, 2.5%, 3%, 3.5% Chinese herbal additives, keep feeding for a week, and feeding once a month until 160 days-old. Pigs in control group without Chinese herbal additives. The results showed that final weight and average daily gain of treatment groups were all better than that of control group(P<0.01);feed/gain in treatment groups were superior to control group, decreased by 0.10~0.30. Based on factors such as final weight, average daily gain, feed/gain, disease incidence and production cost, the optimum ratio of Chinese herbal additives was 2%.
