- Abstract
The experiment was conducted to study the effect of Astragalus, dandelion and honeysuckle compound Chinese herbal medicine on milk production performance and serum biochemical, antioxidant and immune indexes of dairy cows. Twenty Chinese Holstein dairy cows in mid-lactation were randomly selected and divided into four groups, with five replicates in each group and one cows in each replicate. Cows in control group were fed with basal diet, and experimental groups were fed with basal diet supplemented with 100, 200 and 300 g/d Chinese herbal additives, respectively. The pre-test lasted for 10 d and the formal experiment lasted for 21 d. The results showed that the average daily milk yield of cows in group Ⅲ was the highest during 1~3 w, which was significantly higher than that in control group (P<0.05). The milk fat percentage of group Ⅲ was the highest, and that of control group was significantly lower than that of other groups (P<0.05). The somatic cell count of group Ⅲ was the lowest, which was significantly lower than that of control group and group Ⅰ (P<0.05). The activity of AST and CK in serum of cows in control group were the highest, which was significantly higher than those in group Ⅱ and group Ⅲ (P<0.05). The serum IgG content in group Ⅰ was the highest, and significantly higher than that in control group and group Ⅲ (P<0.05). The study indicates that the additive mixture of Astragalus, dandelion and honeysuckle can significantly improve the average daily milk yield and milk fat percentage of dairy cows, improve the liver and kidney functions of dairy cows, but have no obvious effect on milk protein and lactose content of milk, and the appropriate additive amount is 200 g/d.
