头胎与经产奶牛围产期生产性能和血清生化指标的比较
Comparison of Productive Performance and Serum Biochemical Indices of Primiparous and Multiparous Dairy Cows During the Perinatal Period
摘要
Abstract
In order to study the differences of productive performances and serum biochemical indices between primiparous and mulitiparous dairy cows during the perinatal period,ten primiparous and ten multiparous healthy dairy cows were selected and were fed the same total mixed ration.Blood samples were collected from the caudal vein before the morning feeding on-7,-4,-2,-1,0,1,2,4,7 and 14 d after parturition,and serum glucose,triglyceride and calcium concentrations were determined.Milk yields were recorded every day from 11 to 40 days after parturition.Milk samples were collected from each experimental cow on 30th day after parturition and milk compositions and somatic cell counts were determined.The results indicated that no significant difference was observed in serum triglyceride,milk fat,milk protein,milk lactose and milk dry matter between primiparous and multiparous dairy cows(P>0.05).Mutiparous cows had greater daily milk yield and higher milk somatic cell count than primiparous cows(P<0.05).Primiparous cows had significant higher serum glucose level on-4,2 and 4 d after parturition(P<0.05),but significant lower serum glucose level on calving date(P<0.05)when compared with multiparous cows.Higher serum calcium concentrations were found on-2,-1 and 2 d after parturition in primiparous cows than multiparous cows(P<0.05).关键词
