Cows were divided into four groups depend on the last parturition, control group (41) normal cows, inactive ovary group (36) cows, endomitritis (65) cows and septic metritis (41) cows. Also dystocia rate was recorded, Retained fetal membrane, inactive ovary and uterine infections were recorded. Four parameters of reproductive performance were studied, first estrus, first service, open days and no. of services per conception. The results showed a significant (P<0.01) difference between the studied groups for control cows compared with inactive ovary, endometritis and septic metritis cows. The control group recorded (73.3) days for first estrus, (86.6) days for first service, (124.3) open days and (2.5) no. of services per conception .compare with inactive ovary which showed (110.1) days for first estrus, (126) days for first service, (177.6) days open days and (3) no. of services per conception, endometritise group recorded (79.3) days for first estrus, (109.7) days for first service, (145.1) open days and (2.93) no. of services per conception, Finally septic metritis group recoded (91.8) days for first estrus, (110.4) days for first service, (243.3) open days and (3.6) no. of services per conception. It can conclude from this study is the reproductive problems include inactive ovary, endometritis and septic metritis are effect on reproductive performance. | ||
