| Abstract: | 220 Holstein dairy cows were conducted to evaluate the effects of Maillard reaction products(MRPs) on production performance and milk quality.The content of MRPs in concentrate was 1000 mg/kg and the trial period was one month,with the results of corresponding time period in last year as control.The results showed that the milk yield,milk fat and milk protein were increased by 6.81%(P<0.01),3.98%(P<0.01) and 2.44%(P>0.05),respectively.Before supplemented with MRPs,the bacterial number in milk was smaller th... |
