摘要
试验旨在研究中草药添加剂对湖羊羔羊生长性能、血清抗氧化指标、生化指标、免疫指标及瘤胃发酵参数的影响。选取80日龄、体重接近的湖羊公羔30只,随机分为2组,每组3个重复,每个重复5只羊。试验组羔羊精饲料中添加1%自配中草药添加剂。预试期10 d,正式试验期49 d。结果显示:与对照组相比,试验组羔羊的平均日增重提高23.12%(P<0.05),平均日采食量提高5.03%(P<0.01)。试验组羔羊血清球蛋白含量比对照组提高9.35%(P<0.01),碱性磷酸酶活性比对照组提高25.59%(P<0.05),尿素氮含量比对照组低16.45%(P<0.05)。试验组羔羊血清中超氧化物歧化酶活性显著高于对照组(P<0.05),谷胱甘肽过氧化物酶活性极显著高于对照组(P<0.01)。试验组羔羊血清中免疫球蛋白G含量显著高于对照组(P<0.05)。试验组羔羊瘤胃液pH值显著高于对照组(P<0.05),微生物蛋白浓度比对照组高40.77%(P<0.05),丙酸浓度比对照组高7.95%(P<0.05),丁酸浓度比对照组高32.86%(P<0.01),总挥发性脂肪酸浓度比对照组高19.21%(P<0.05)。研究表明,中草药添加剂能够有效提高湖羊羔羊生长性能,增强免疫力,改善瘤胃发酵环境。
The experiment was to study the effect of Chinese herbal medicine additives on growth performance, serum antioxidant indexes, serum biochemical indexes, serum immune indexes and rumen fermentation parameters of Hu sheep lambs. Thirty 80-day-old male Hu sheep lambs with similar body weight were selected and randomly divided into two groups, with three replicates in each group and five sheep in each replicate. 1% self-prepared Chinese herbal medicine additives were added to concentrated feed of lambs in experimental group. The pre-trial period was 10 d, and the formal experimental period was 49 d. The results showed that compared with control group, the average daily gain of lambs in experimental group was increased by 23.12%(P<0.05), and the average daily feed intake was increased by 5.03%(P<0.01).The serum globulin content of lambs in experimental group was higher than that in control group by 9.35%(P<0.01), the alkaline phosphatase activity was higher than that in control group by 25.59%(P<0.05), and the urea nitrogen content was lower than that in control group by 16.45%(P<0.05). The activity of superoxide dismutase in serum of lambs in experimental group was significantly higher than that in control group(P<0.05), and the activity of glutathione peroxidase was extremely higher than that in control group(P<0.01). The serum immunoglobulin G content of lambs in experimental group was significantly higher than that in control group(P<0.05). The pH value of lamb rumen juice in experimental group was higher than that in control group(P<0.05), the concentration of microbial protein was higher than that in control group by 40.77%(P<0.05), and the concentration of propionic acid was higher than that in control group by 7.95%(P<0.05). The concentration of butyric acid was higher than that of control group by 32.86%(P<0.01), and the concentration of total volatile fatty acids was higher than that of control group by 19.21%(P<0.05). The experiment indicates that Chinese herbal medicine additives can effectively improve the growth performance, enhance immunity, improve the rumen fermentation environment of Hu sheep lambs.
