Dynamics of ovarian structures after aplication of Suprelorin® (4.7 mg de-slorelin acetate) implant for estrus induction in bitches

The sexual cycle and ovulation in bitches occur much less often than other domestic animals, as they are monoestrous. In addition, dogs have spontaneous and, consequently, a luteal phase. This physiology of the leads to specific difficulties with reproduction. Owners cannot connect bitch dog time accordingly, get offspring due absence heat or prolonged anestrus. Therefore, stimulation is gaining more interest among animal owners. Understanding its stages makes it possible manipulate safely without negative consequences for bitch's body. We recommend using Suprelorin implant late anestrus induce estrus obtain bitches. Implant Suprelorin®, primarily registered pharmacological sterilization cats, causes at beginning action. mechanism action Deslorelin implants known flare effect stimulating on secretion gonadotropin (GnRH), which triggers synthesis follicle-stimulating luteinizing hormones from pituitary gland. Our results showed that use Suprelorin® (4.7 mg Deslorelin) safe induction oestrus does not cause side effects. proposed scheme achieve highest level initiation (hypothalamus-pituitary-gonads), close natural regarding Ultrasound diagnostics occupy an essential place studying animals gynecological problems. There many studies would show dynamics ovarian follicles after implant. our studies, ultrasonographic examination structures revealed faster appearance group treated mg) compared control group; same time, their size was significantly extensive, ovulated faster. anechoic ovaries 3 mm (mean 3.2 ± 0.1) detected already third day introduction 3/6 experimental group, while only fifth (4/6) seventh (2/6) day. Follicle sizes differed statistically between groups 9th 12th noted earlier (starting day); were extensive 14th day, 16th
