Drug Type: GnRH-agonist

Deslorelin acetate

Deslorelin acetate acts like the natural gonadotropin-releasing hormone (GnRH) which controls the secretion of other hormones in order to stop ovulation in female poultry (stop them from laying eggs).

How Deslorelin is Administered

Deslorelin acetate comes in the form of a 4.7 mg or 9.4 mg implant which is inserted by your veterinarian subcutaneously, under the skin of the bird.

How Long the Effects of Deslorelin Last

The implant starts being effective after about 2 to 6 weeks. The duration of its effectiveness is highly variable, and differs from bird to bird. In dogs, the effectiveness has been reported to last up to 6 months in the case of the 4.7 mg implant and 12 months in the case of the 9.4 mg implant, after which a re-implant is necessary.

How it Works

Once given to the bird, the implant releases deslorelin into the bird's system gradually, over the course of several months. Deslorelin blocks the production of follicle stimulating hormone (FSH) and luteinising hormone (LH) in implanted birds. This results in less testosterone circulating in the bird's blood which in turn, decreases egg production.
