Relationship among body condition score, some biochemical parameters and uterine involution in dairy cow

The objective of this study was to identify the relationship among body condition score (BCS) at the time around parturition, some indicators of biochemical status and the uterine involution. The BCS was measured once a month and the cows were divided into groups according to their BCS at calving and after calving. The Blood content creatinine and phosphorus was measured the day of calving, 30 days and 60 days postpartum and the Blood content creatine kinase was measured the day (d) of calving, 15 days , 30 days and 45 days postpartum. The data set was analyzed by the Student test comparison of two means using statistical program XL stat. Cows with lower BCS at calving showed a raise blood phosphorus (88.015 mg / l) and a raise blood créatinine (15.415 mg / l) and significantly (P < 0.05) differed from those detected in cow with the highest BCS level and the cow with average BCS level. No differences significant was found between the concentration blood creatine kinase at calving (160.70 IU) and at fifteenth days of postpartum (PP) (142.91 IU) in cow with lower BCS. In conclusion, we can say that the lean cow use the phosphagen source to ensure the smooth progress of uterine involution after parturition
