| Abstract: | In this experiment,forty tested cows that were from an intensive dairy farm were divided randomly into eight groups（in turn I,Ⅱ,Ⅲ,Ⅳ,10 cows per group）,according to different dosage of rumen-protected betaine（5,10,20 and 0 g dosage of betaine,per day for each cow） supplemented into diet from day 14 before calving to day 42 after calving.Meanwhile,effect of rumen-protected betaine on milk yield and production performances.Results showed that compared to control group,milk fat rate significantly increases in groupⅦ（P0.05）;there is a no significant diference in milk protein rate,lactose,and non-fat solidin all test groups（P0.05）.dry matter intake increase markedly in group Ⅶ（P0.05）,and milk yield increased very significantly in Ⅱ group（P0.01）.Conclusion obtained that 20 g rumen-protected betaine per cow may more effectively improve milk performance and reproductive performance of dairy cows. |
