Pregnancy rate in Bulgarian White milk goats with natural and synchronized estrus after artificial insemination by frozen semen during breeding season

Conclusion The goats with natural estrus and GnRH treatment tend to enhance pregnancy rate after double artificial insemination 8 hours apart. The insemination number has no significant impact on pregnancy rate in synchronized goats as the overall pregnancy rate is better than in animals with natural estrus without GnRH administration.
