摘　　要：试验旨在研究杜仲提取物对犊牛生长性能及血清指标的影响。试验采用单因素随机区组设计,选取自然分娩的健康新生荷斯坦犊牛30头,随机分为对照组和试验组,每组15个重复,每个重复1头牛。对照组饲喂基础饲粮,试验组饲喂基础饲粮+2 kg/t杜仲提取物,试验期62 d。结果显示,试验组犊牛的平均日增重高于对照组(P>0.05);试验组的轻度腹泻频率和总腹泻频率均极显著低于对照组(P<0.01);试验组的血清白蛋白(ALB)、白细胞介素-4(IL-4)、白细胞介素-10(IL-10)含量和谷胱甘肽过氧化物酶(GSH-Px)活性显著高于对照组(P<0.05),肿瘤坏死因子-α(TNF-α)含量显著低于对照组(P<0.05)。研究表明,在犊牛饲粮中添加2 kg/t杜仲提取物,可以提高犊牛抗炎和抗氧化能力,降低腹泻率,提高生长性能。The experiment aimed to study the effects of Eucommia ulmoides extract on the growth performance and serum indexes of calves.A single-factor randomized block design was used,selecting 30 healthy newborn Holstein calves delivered naturally,randomly divided into a control group and an experimental group,with 15 replicates in each group,and one calf per replicate.The control group was fed a basic diet,while the experimental group was fed a basic diet plus 2 kg/t of Eucommia ulmoides extract for 62 days trial period.The results showed that the average daily weight gain of the calves in the experimental group increased compared to the control group(P>0.05).The frequency of mild diarrhea and total diarrhea in the experimental group were extremely reduced compared to the control group(P<0.01).The levels of serum albumin(ALP),interleukin-4(IL-4),interleukin-10(IL-10),and activity of glutathione peroxidase(GSH-Px)in the experimental group were significantly higher than those in the control group(P<0.05),while the contant of tumor necrosis factor-α(TNF-α)was significantly lower than that in the control group(P<0.05).The study indicates that adding 2 kg/t of Eucommia ulmoides extract to the feed of calves can enhance their anti-inflammatory and antioxidant capabilities,reduce the incidence of diarrhea,and improve growth performance.
