Abstract: In order to study the effect of feeding patterns (extensive feeding pattern (EP),complete intensive feeding pattern (CP) and incomplete intensive feeding pattern (IP)) on serum biochemical indices and hormone content in dairy cows.30 cows with similar body weight,parity and lactation for each pattern were selected to conduct the research,blood samples were collected to detect biochemical indices and related metabolic hormones,so as to analyze theirs relationship with different feeding patterns.The results showed that the serum contents of GLU,ALB,NEFA,BHB,ALT,ALP,LPS and HIS of CP and IP patterns were higher than that of EP pattern,but the serum contents of IgG,IgA and TA of CP and IP patterns were significantly lower than that of EP pattern (P<0.05).The serum contents of INS,INS/GC,T3 and GH of CP and IP patterns were higher than that of EP pattern,but the serum content of GC of CP and IP patterns was lower than that of EP pattern.In conclusion,feeding patterns had different degree effect on serum biochemical indexes and related hormones secretion of dairy cows,and CP pattern was better than IP and EP patterns.
