Abstract:The aim of this study was to detect the effects of compound feed additives on production performance,serum biochemical of Holstein cows.A single-factor experiment was adopted in the study,and 18 Holstein cows with similar health and body condition in mid-lactation were randomly divided into 2 groups,namely the control group and experiment group(addition of compound feed 200g/d).There were 3 repetitions in the both two groups,and each repetition with 3 Holstein cows,the experiment lasted 30 days.On the 15th and 30th day,milk samples and fasting blood samples of cows were collected to determine their milk production performance and serum biochemical indicators.The results showed that:on the 15th and 30th days,serum albumin,urea nitrogen,triglycerides,cholesterol,glucose,aspartate aminotransferase and alanine aminotransferase of the cows in the compound feed group were increased compared with the control group,but the changes were not significant(P>0.05);the experiment group’s serum total protein content was higher than the control group(P<0.05);the milk yield of the cows in the compound feed additive group at 15d and 30d were(21.55±4.03)kg and(22.63±1.76)kg,compared with the control group,increased 9.27%and 14.2%respectively(P<0.05);in addition,the number of somatic cells and urea nitrogen levels in the milk samples of the experiment group were lower than the control group,but only urea nitrogen was significantly reduced(P<0.05).To sum up,the compound feed additive can increase the content of serum total protein,the milk production of cows in the middle or late stages of lactation and improve milk quality.
Keywords:compound feed additives  Holstein cows  production performance  serum biochemical indexes
