The influence os factors predisposing for the implications of cyst follicular
Keywords:
Gynecological examination, Ovarian cyst, Holstein cowsAbstract
We studied the incidence of follicular cysts in dairy cows of Holstein in a commercial farm, which is localized in the Uberlândia- MG. We analyzed 304 lactation cows with average production of milk was 20,45kg, for the period of one year. The diagnosis were made every 21 days, totaling 423 gynecological examinations. In the visits were collected: days postpartum, ultrasound evaluations and relationship between cysts and date of parturition and diagnosis. Cows were considered cystic whose had follicles with at least 25mm of diameter, in the absence of corpus luteum. The effects of the postpartum, the diagnosis station and the calving season under the occurrence of ovarian cysts were analyzed by logistic regression with the program MINITAB. Ovarian follicular cysts incidence was 2.63%. There were no effects of days postpartum, season of diagnosis and season of calving on incidence of follicular cysts, but cyclicity was affected by season of calving.
