This study was undertaken to investigate the relationship between body condition score and blood levels of Ca, Mg, P, Glucose, Urea and Triglyceride and occurrence of retained placenta and dystocia in cows. Serum samples from 46 cows were analyzed (26 with retained placenta, 22 with dystocia). Our results show that cows have a percentage of occurrence of dystocia and retained placenta at a rate of 68.18%, 57.69% respectively and that the lean and fat cows have a rate of dystocia almost identical of 40.90% , 36.36% respectively, these cows presente an hypocalcemia with a rate of (38.89, 38.89)%, hypophosphatemia with a rate of (38.46, 30.76)%, hyperglycemia with a rate of (46.66, 33.33)% and hypertriglyceridemia with a rate of (60, 26.66)%. We also noted that placental retention rate is of 61.53% touching the fat cows and that these cow have significant metabolic disturbances: hypocalcemia, hypophosphatemia with a rate of 83.33%, hypomagnesemia with rate of 82.35%, hypoglycemia of the order of 84.21% and a hyperuremia with a rate of 80% (P < 0.001). It was also noted that the lean cows affected with retained placenta show an uremia were significantly lower than the fat cows with a rate of 71.42%. It is concluded that lower serum (Ca, P) and higher serum (glucose and triglycéride) for fat cows or lean cows may induce the dystocia and lower serum (Ca, P, Mg, glucose) and higgher serum urea in fat cows and lower serum urea in lean cows may induce placenta retention.
