摘要:

试验旨在探究三株益生菌发酵中草药对断奶羔羊生产性能、血清生化指标及免疫机能的影响。试验选取外表健康、体重相近(15.19±0.81)Kg的小尾寒羊100只,随机分为5组,每组4个重复,每个重复5只。试验Ⅰ、Ⅱ、Ⅲ、Ⅳ组分别在基础日粮中添加0%、0.5%、1.0%、1.5%的发酵中药制剂,试验Ⅴ组添加1.0%的纯复方中草药制剂,预试期3d,正试期40d。结果显示,试验Ⅲ、Ⅳ、Ⅴ组的平均体重显著高于对照组(P<0.05),且Ⅱ组与Ⅳ组间有显著差异(P<0.05)；试验Ⅱ、Ⅲ、Ⅳ、Ⅴ组的ADG显著高于对照组(P<0.05),且Ⅱ组与Ⅲ、Ⅳ、Ⅴ组间有显著差异,Ⅳ组与Ⅲ、Ⅴ组间有显著差异(P<0.05)；试验Ⅲ、Ⅳ、Ⅴ组的ADFI显著高于对照组(P<0.05),且Ⅱ组与Ⅳ组间有显著差异(P<0.05)。试验Ⅲ、Ⅳ、Ⅴ组的TP含量显著高于对照组(P<0.05)；试验Ⅲ、Ⅳ、Ⅴ组的GLO含量显著高于对照组(P<0.05),且Ⅲ组与Ⅰ、Ⅱ组间有显著差异(P<0.05)；Ⅲ组的ALP含量显著高于对照组(P<0.05)。Ⅲ组和Ⅳ组的IL-2含量显著高于对照组(P<0.05),且Ⅲ、Ⅳ组与Ⅱ组间有显著差异(P<0.05)；Ⅱ、Ⅲ、Ⅳ、Ⅴ组的IgA含量显著高于对照组(P<0.05),且Ⅲ、Ⅳ组与Ⅱ、Ⅴ组间有显著差异(P<0.05)；Ⅲ组的IgG含量显著高于对照组(P<0.05),且Ⅱ组与Ⅲ组间有显著差异(P<0.05)。综上,三株益生菌发酵复方中草药制剂能显著提高断奶羔羊的生产性能和免疫机能,且能改善其血液生化指标,且以1.0%的比例为最适添加比例。

Abstract:

The experiment aimed to investigate the effects of three probiotic fermented herbal supplements on the production performance, serum biochemical indices and immune function of weaned lambs.A total of 100 small-tailed Han sheep with similar appearance and body weight (15.19±0.81 kg) were selected and randomly divided into 5 groups, with 4 replicates in each group and 5 sheep in each replicate.Group I, II, III and IV were supplemented with 0%, 0.5%, 1.0% and 1.5% fermented traditional Chinese medicine preparations to the basic diet, while group V were added 1.0% pure compound herbal supplements to the basic diet, with a pre-trial period of 3 days and a main trial period of 40 days.The results showed that the average body weight of the test groups III, IV, and V was significantly higher than that of the control group (P<0.05), and there was a significant difference between group II and IV(P<0.05);? the ADG of the test groups II, III, IV, and V was significantly higher than that of the control group (P<0.05), and there were significant differences between groups II, III, IV, and V and group II (P<0.05), and between groups IV and III, and V (P<0.05); the ADFI of the test groups III, IV, and V was significantly higher than that of the control group (P<0.05), and there was a significant difference between groups II and IV (P<0.05). The TP content of the test groups III, IV, and V was significantly higher than that of the control group (P<0.05); the GLO content of the test groups III, IV, and V was significantly higher than that of the control group (P<0.05), and there was a significant difference between groups III and I, II (P<0.05); the ALP content of group III was significantly higher than that of the control group (P<0.05). The IL-2 content of groups III and IV was significantly higher than that of the control group (P<0.05), and there was a significant difference between groups III, IV and II (P<0.05); the IgA content of the test groups II, III, IV, and V was significantly higher than that of the control group (P<0.05), and there were significant differences between groups III, IV and II, V (P<0.05); the IgG content of group III was significantly higher than that of the control group (P<0.05), and there was a significant difference between groups II and III (P<0.05). In conclusion, the three probiotic fermented compound herbal preparations can significantly improve the productive performance and immune function of weaned lambs, and can also improve their blood biochemical indicators, with the optimal addition ratio is 1.0%.
