【摘要】：为研究饲粮中添加芦根对热应激泌乳奶牛免疫功能和血液指标的影响,采用完全随机区组试验设计,根据产奶量、泌乳时间、胎次将30头健康的泌乳荷斯坦奶牛随机分为空白对照组、芦根处理组和复方制剂处理组,其中空白对照组饲喂基础日粮,芦根处理组饲喂基础日粮+30 g/d芦根,复方制剂组饲喂基础日粮+复方制剂35 g/d,试验期34 d。结果表明:芦根能使机体免疫力增强,夏季可以通过添加芦根和复方制剂来改善奶牛的免疫力。饲喂芦根后可对肝脏有一定的修复作用,能显著增加血液Na~+、Ca~(2+)、Mg~(2+)浓度(P005),提高机体的抗病能力,改善其亚健康状态。因此,夏季补饲30 g/d芦根有助于缓解热应激奶牛机体代谢紊乱,从而改善奶牛的免疫机能。
[Abstract]:In order to study the effect of root root on immune function and blood index of heat stress lactating cows, a complete randomized block design was used to study the effects of root root on milk production and lactation time. Thirty healthy lactating Holstein cows were randomly divided into three groups: blank control group, Reed root treatment group and compound preparation treatment group. The blank control group was fed basic diet, and the Reed root treatment group was fed 30 g / d Reed root. Compound preparation group was fed with basic diet compound preparation 35 g / d for 34 days. The results showed that Lugen could enhance the immunity of the body. In summer, the milk cow's immunity could be improved by adding root and compound preparation. After feeding root, the liver could be repaired to a certain extent, and the concentration of blood Na ~ (2 +) ~ (2) Cam _ (2) and mg ~ ((2)) could be significantly increased (P _ (005)), and the disease resistance of the body could be improved. Therefore, supplementation of 30 g / d root in summer can alleviate metabolic disorder and improve immune function of dairy cows under heat stress.
