Summary
Controlling the estrous cycle and superovulation in goats involves progestagen treatments and FSH administration. Advanced techniques like transcervical embryo collection and in vitro fertilization offer promising biotechnological applications in ruminants.
Area of Science:
- Reproductive biology
- Animal biotechnology
- Veterinary science
Context:
- Estrous cycle control and superovulation are critical for efficient goat breeding and research.
- Current methods involve progestagen pessaries/implants for cycle control and FSH for superovulation.
- Inhibin immunization presents an alternative superovulation strategy.
Purpose:
- To review and synthesize current techniques for estrous cycle control and superovulation in goats.
- To discuss embryo collection, transfer, in vitro culture, and preservation methods.
- To highlight the potential of goats as a model for ruminant biotechnology.
Summary:
- Progestagen pessaries or subcutaneous implants are commonly used for estrous cycle control in goats.
- Follicle-stimulating hormone (FSH) is preferred over pregnant mare serum gonadotropin (PMSG) for superovulation.
- Embryo collection and transfer typically involve laparotomy, with transcervical techniques emerging.
- In vitro embryo culture, cryopreservation (including vitrification), embryo splitting, fusion, and in vitro fertilization are feasible in goats, similar to cattle.
Impact:
- Establishes a comprehensive overview of reproductive biotechnologies in goats.
- Identifies challenges such as premature luteolysis in superovulated goats.
- Positions the goat as a valuable model for advancing ruminant reproductive technologies and biotechnological innovations.
