【摘要】：试验旨在研究饲粮中添加八角和杜仲叶提取物对断奶仔猪生长性能、血清代谢产物及肠道健康的影响,并探索其作用机制。采用单因子试验设计,选择健康的里岔黑断奶仔猪48头,随机分为4个组,每组3个重复,每个重复4头断奶仔猪。对照组饲喂基础饲粮,试验组在基础饲粮的基础上分别添加八角提取物(500 mg/kg)、杜仲叶提取物(250 mg/kg)和金霉素(50 mg/kg)。预试期7 d,正试期42 d。结果表明:与对照组相比,八角、杜仲组和抗生素三组,显著提高断奶仔猪平均日增重(ADG)(P0.05)。八角组显著提高血清总蛋白(TP)含量(P0.05);八角组和杜仲组显著降低了血清尿素氮(SUN)含量(P0.05)。八角组和抗生素组显著降低了盲肠大肠杆菌的数量(P0.05)。由此可见,在饲粮中添加八角、杜仲叶提取物可提高仔猪生长性能和免疫力,并对抗生素具有一定的替代作用。
[Abstract]:The purpose of the experiment was to study the effects of octagonal and Eucommia ulmoides leaf extract on growth performance, serum metabolites and intestinal health of weanling piglets, and to explore its mechanism. Using single factor design, 48 healthy Richahei weanling piglets were randomly divided into 4 groups with 3 repeats in each group and 4 weanling piglets in each group. The control group was fed with basic diet, and the experimental group was supplemented with octagonal extract (500 mg/kg), Eucommia ulmoides leaf extract (250 mg/kg) and chlortetracycline (50 mg/kg). The pre-trial period was 7 days, and the ongoing trial period was 42 days. The results showed that compared with the control group, octagonal group, Eucommia ulmoides group and antibiotic group significantly increased the average daily gain of weanling piglets (P 0.05). Octagonal group significantly increased serum total protein (TP) content (P 0.05), octagonal group and Eucommia ulmoides group significantly decreased serum urea nitrogen (SUN) content (P 0.05). Octagonal group and antibiotic group significantly decreased the number of cecal Escherichia coli (P 0.05). It can be seen that the extract of Eucommia ulmoides leaves can improve the growth performance and immunity of piglets by adding octagonal to the diet, and has a certain substitution effect on antibiotics.
