Effects of Eucommia ulmoides extract on growth performance and serum indexes of calves
摘要
Abstract
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.关键词
