日粮中添加发酵黄芩对断奶仔猪生长性能的影响

选用64头28日龄(长大二元)断奶仔猪,随机分为4个处理组,每组4个重复,每个重复4头猪。各处理组分别在基础日粮基础上添加0(对照组)、0.1%、0.15%、0.2%的发酵黄芩。试验期为28 d。结果表明,日粮中添加发酵黄芩能增强断奶仔猪食欲,提高采食量,降低料肉比、腹泻率,提高饲料报酬。通过对不同水平的比较,发现发酵黄芩添加水平为0.15%效果最优,日采食量、日增重较对照组提高12.9%(P<0.05)、33.0%(P<0.05),料肉比、腹泻率较对照组降低15.0%(P<0.05)、30.6%(P<0.05)。

Sixty four 28-day-old weaned piglets （YorkshirexLandrace）were randomly divided into 4 groups with 4 repetitions of 4 each.The 4 experiment groups were fed basal diet supplemented with 0 （control group） ,0.1% ,0.15 %, 0.2 % fermented scutellaria.The experiment lasted for 28 days.The results showed that：the optimum adding levels of fer-mented scutellaria was 0.15 %.Compared with control group,feed intake and daily gain were increased by 12.9 % （P 〈 0.05 ）33.0 % （P 〈 0.05 ）,feed conversion rate and diarrhea rates decreased by 15.0 % （P 〈 0.05 ）, 30.6 % （P 〈 0.05 ）.
