Effect of Treated Genital Diseases on the Number of Services per Conception in Dairy Cattle

[摘要] This research is applied on small private fields of lactating cows located in Sulaimania region. One hundred fifty four lactating non pregnant cows involved in this study, from which 31 cows (20.13%) suffered from uterine infections, 41 cows (26.63%) were with ovarian problems and 82 (53.24%) were clinically normal cyclic cows. Cows suffered from genital disorder were treated according their reproductive state.All clinically normal cows and cows responded to treatment were observed for detection of estrous and inseminated artificially, and number of services per conception (SPC) were recorded. Number of services per conception (SPC) for clinically normal cyclic cows was 2.0±0.10.In our study, we reported for the first time, that SPC were 1.0±0.00, 1.2±0.20 and 1.7±0.15 for cows treated from luteal cystic ovaries, inactive ovaries and persistence corpus luteum respectively, and the Mean ± S.E. of SPC for this category of cows was (1.54±0.15), While a very high SPC were necessary for cows treated from uterine infections; 4.0±0.24, 4.4±0.25 and 5.0±0.45 were recorded for cows treated from endometritis, toxic puerperal metritis and metritis respectively, and the Mean ± S.E. of SPC for this category of cows was (4.39±0.34).
