Effect of Compound Bacteria Culture on Milk Production and Somatic Cell Counts of Dairy Cattle
摘要
Abstract
The effect of compound bacteria culture on the milk production,milk quality and somatic cell counts of dairy cows were examined in this study. Thirty Holstein dairy catties were selected and divided into test group and control group. The control group was fed with the basal diet,and the test group was fed with 400 g compound bacteria culture per cow for one day in the basal diet. The experiment lasted for 37 d. The milk production,milk fat,milk protein percentage and somatic cell counts were determined. The results showed that the milk production of test group increased 6. 84% (P>0. 05) ,and the decline rate of milk somatic cell counts increased 29. 78% (P<0. 05) compared with the control group. Milk fat and milk protein had no significant differences (P>0. 05) between two groups. These results indicated that compound bacteria culture could improve the lactation ability and significantly reduce the somatic cell counts of dairy catties.关键词
