Abstract: 80 dairy cows were selected in order to observe the prevention and cure effect and immunological enhancement of the traditional Chinese medicine complex perfusion fluid to mastitis. The SCC,SA,ALT,AST,LDH,SI,the rate of neutrophil phagocytosis of dairy cows with mastitis during cure were measured,and the incidence of mastitis was observed in the dry period. The results showed that the cure rate of sub-clinical mastitis by traditional Chinese medicine complex perfusion fluid and antibiotics were respectively 94.44% and 88.24%,and the effective rate were 100%. The cure rate of clinical mastitis in dairy cows were respectively 86.67% and 84.62%,and the effective rate were 93.33% and 91.67%. The preventive effects of mastitis in dry period were 88.89% and 94.12%,while the incidence rate in the control group was 42.86%. The levels of SCC,SA,ALT,AST,LDH were significantly decreased by the traditional Chinese medicine complex perfusion fluid,and the levels of SI and the rate of neutrophil phagocytosis were significantly increased (P<0.01). The experiment showed that the traditional Chinese medicine complex perfusion fluid had a better treat effect on mastitis,which can repair damaged mammary gland epithelial cells and reduce the permeability of the blood-milk and the activity of the enzymes in milk. It can improve the immune function of cows.
