Acetato de deslorelina como agente indutor de ovulação em éguas

The mares are seasonal reproductive animals, being influenced by the changes in the daily relation of luminosity during the year, presenting a greater difficulty in the control of the estrous cycle when compared to the cattle. The use of ovulation inducers can improve reproductive efficiency by synchronizing the time of ovulation and reducing the period of estrus. The objectives of this paper were to evaluate the use of progesterone-device for cow estrous induction and ovulation time in mares using deslorelin acetate as an ovulation inducer. Five mares of reproductive age were used, which had their estrus induced twice each. In one of them it was administered with 750 mg of deslorelin acetate. For estrous induction, a 5mg dose was administered via IM of prostaglandin F2alpha at the D0 and an intravaginal device was inserted, which was removed at D8, and a dose of prostaglandin was administered concomitantly. After removal of the vaginal devices follicular growth was evaluated at 12 / 12h intervals until ovulation. All animals showed estrus behavior. Mares treated with deslorelin acetate had a mean ovulation time of 43.2 ± 6.57 while the untreated group was 84.0 ± 14.70, with a significant difference. It

ALTERAÇÕES EM ÓRGÃOS GENITAIS DE CÃES E GATOS HÍGIDOS

There are several diseases capable of causing alterations in the genital organs (GO) in domestic animals. In order to evaluate the GO of healthy dogs and cats surgically sterilized, establishing the prevalence of alterations of these, the excised OGs were analyzed macro and microscopically. The descriptive results showed that 92 animals whose GO were studied, 66.3% (61/92) were canine, 33.7% (31/92) felines and 11.95% (11/92) presented alterations. The canines presented greater number of alterations in the GO, being observed in eight bitches, two male dogs and one female cat. 10.87% (10/92) of the alterations were observed in pure breed animals (28 animals), although undefined breed animals were more numerous (64 animals: 37 canines and 27 felines). The mean age and weight of the animals that presented alterations were 59.7 + 32.4 months and 84 months, and 13.8 ± 13.7 and 4.5 Kg, respectively, for canines and felines, respectively. In the conditions of this study, it was concluded that dogs which were submitted to surgical sterilization more frequently than cats had a higher occurrence It is also suggested that females of pure breeds, age and weight are more susceptible to changes in GO.
