SUIDAE

Recommendations

1. GnRH Agonists - Gonadotropin Releasing Hormone Agonists are considered the safest reversible contraceptives, but dosages and duration of efficacy are not well established for all species; side effects are generally similar to those associated with gonadectomy, especially the potential for weight gain unless diet is controlled; they have not been effective in male artiodactyls. They have not been tested in male suidae.
   • Suprelorin® (deslorelin) Implant (F)
   • Lupron® Injection (F)
2. MGA Implant (F)
3. Depo-Provera® (F)

Cautions

1. Synthetic progestins may cause endometritis, pyometra and hydrometra
2. Pregnant artiodactyls contracepted with progestins may be especially susceptible to suppression of uterine contractions; progestins should only be administered to animals CONFIRMED not pregnant.
3. Depo-Provera may be a particular problem in pregnant females, since length of efficacy is so variable (approximate range: 2-24 months)
4. GnRH agonists may not be effective in male bovids; effectiveness unknown for other artiodactyls
5. MGA feed and MGA liquid not recommended for suids; dose required for efficacy associated with side-effects. The PZP Vaccine is not effective either, because it will not elicit an immune response in suids.

Research and Monitoring

Surveillance for deleterious effects
• Contraception Annual Survey
• Tissue Submission Form – Pathology
• Adverse Reactions Report

THE USE OF ANY CONTRACEPTIVE IN NON-DOMESTIC ANIMALS IS CONSIDERED EXPERIMENTAL

(M=MALE-DIRECTED, F=FEMALE-DIRECTED METHOD)
