Effect of deslorelin on the induction of estrus in anestrous bitches. Lanna I , A. Marques Jr. Douglas III. The efficacy of one or multiple doses of an injectable formulation of deslorelin a GnRH agonist was evaluated to induce estrus in anestrous bitches.
A male dog was used in the beginning of the experiment until the cytological characterization of deslorlin to evaluate the sexual behavior of the females. Thus, with careful placement, removal is ovultion. Other sources of information Fontaine E, Fontbonne A Use of deslorelin to control fertility in the bitch. Consideration for seasonal breeders — In females, GnRH agonists can induce estrus Dogs deslorelin ovulation ovulation even during the non-breeding season in Dogs deslorelin ovulation taxa.

Deslorelin implants are available in two formulations: mg for a minimum of 6-months, and mg for a minimum of months of contraception. Because deslorelin was tested first in domestic dogs and cats, it was considered most suitable for carnivores but is now used successfully in females of many other taxa. Deslorelin has a biopotency about x GnRH and the implants likely provided doses of ug/kg/d in beagle-sized dogs based on manufacturer's claimed release rates. However, pregnancy maintenance and litter sizes varied among trials. Implants of the agonist leuprolide have also been successfully used. Analog (deslorelin) for Ovulation Induction in Mares. DIN For Veterinary Use Only. Description. OVUPLANT (deslorelin) is a synthetic GnRH analog in a biocompatible sustained release subcutaneous implant with the indication to induce ovulation in the estrous mare within 48 hours.
Dogs deslorelin ovulation. Introduction
Prediction of the oocyte recovery rate in the bitch. Latency to effectiveness - Because the initial effect is to stimulate the reproductive system, it is important to either separate treated animals from opposite sex individuals during the period of enhanced fertility or use another form of contraception. Based on previous reports and in the potential of GnRH agonists in the induction of estrus in bitches, the present study evaluated the effect of an injectable intramuscular formulation of deslorelin in anestrous bitches, testing one or multiple applications in the induction of estrus and ovulation, and its effects on the reproductive system. J Reprod Fertil 57 , PubMed. Ovary and uterus. One animal presented clinical signs, vaginal cytology, and sexual behavior of estrus, similar to the other responsive bitches; however, it did not ovulate. Biology and endocrinology of ovulation, pregnancy and parturition in the dog. The estrus duration was 6. CAIN, J. It can, however, be used to ameliorate aggression in males of some species, but higher dosages are usually needed. In males, muscle loss may result in overall weight loss if not replaced by fat. Estrus induction and synchronization in canids and felids.
A number of methods to induce estrus in dogs have been reported. It is because of such variation in "responses" to many protocols that the bitch should be carefully monitored for clinical signs including vaginal cytology and changes in vulval and vaginal morphology, as performed for any critical managed breeding, and also monitored for changes in circulating progesterone concentrators that can differentiate between a false and ovulatory estrus. The basic endocrinology of the normal ovarian cycle in dogs involves the following observed changes in peripheral concentrations of hormones and accompanying clinical changes. During anestrus, progesterone concentrations decline to their lowest values, typically well below 0. The normal stimuli for the initiation of proestrus and the associated sequence of changes in hypothalamic, pituitary and ovarian activity are not fully understood. The presumptive basis of this change in pituitary hormone secretion is an increase in the pulse frequency and possibly pulse magnitude of the GnRH released by the hypothalamic GnRH-secreting neurons and possible changes in the sensitivity of the pituitary to GnRH.
