Investigation on the Efficacy of Compound Chinese Herbs on Pasteurellosis in Dairy Cows in Large-scale Dairy Farms
[Objective]To investigate the efficacy of compound Chinese herbs against Pasteurellosis in dairy cows in large-scale dairy farms.[Method]Sixty cows suffering from Pasteurellosis in a large-scale dairy farm in Linyi City,Shandong Province,were randomly divided into four groups.The cows in the control group were fed normal diets without treatment,and the cows in the test groups Ⅰ to Ⅲ were treated with 50,100,and 150 mL of the compound herbal preparation daily.[Result]Compared with the control group,the test groups showed good therapeutic effects,and the cure rates and effective rates of the cows in the test groups Ⅰ,Ⅱ,and Ⅲ were 53.33％,66.67％,80.00％,and 86.67％,respectively,93.33％and 100.00％,respectively.On the 5th day after the administration of the drug,the body temperature of the affected cows in test groups Ⅱ and Ⅲ was significantly reduced(P<0.05),and the respiratory rate and heart rate of the affected cows in test groups Ⅰ,Ⅱ and Ⅲ were significantly reduced(P<0.05);on the 10th day after the administration of the drug,the body temperature,respiratory rate and heart rate of the affected cows in test groups Ⅰ,Ⅱ and Ⅲ were significantly reduced(P<0.05).On the 5th day after drug administration,the average daily weight gain,milk yield and feed efficiency of the affected cows in test groups Ⅰ,Ⅱ and Ⅲ were significantly higher(P<0.05),and the average daily feed intake of the affected cows in test groups Ⅱ and Ⅲ were significantly higher(P<0.05);on the 10th day after drug administration,the average daily weight gain,average daily feed intake,milk yield and feed efficiency of the affected cows in test groups Ⅰ,Ⅱ and Ⅲ were significantly higher(P<0.05).[Conclusion]Compound Chinese herbal medicine has good therapeutic effect on Pasteurellosis in dairy cows in this large-scale dairy farm,which can effectively and rapidly reduce clinical symptoms,and the efficacy is dose-dependent.
