Aşım Sezonunda Şami Keçilerinde Progestagen İçeren Deri Altı İmplant ve Vaginal Süngerlerin Uzun ve Kısa Süreli Uygulamalarının Fertilite Üzerine Etkisi

Abstract

27.7±0.5 h after the sponge removal in the LTS, STS, LTI and STI groups, respectively. The estrous rates were detected as 95.4%, 95.4%, 95.4% as 86.3% in the LTS, STS, LTI and STI groups, respectively. The pregnancy rates were 72.7%, 68.2%, 72.7% and 68.3% in the LTS, STS, LTI and STI groups respectively. The conception rates were found to be 76.1%, 71.4%, 76.1% and 78.9% in the LTS, STS, LTI and STI groups respectively. The kidding rates were found to be 93.8%, 86.7 %, 87.5% and 93.3% in the LTS, STS, LTI and STI groups respectively. The prolifi cacy rates were 133%, 130%, 135% and 128% in the LTS, STS, LTI and STI groups respectively. No statistical difference were found in the estrous response time, estrous rate, pregnancy rate, conception rate, kidding rate and the prolifi cacy rates among the LTS, STS, LTI and STI groups (P>0.05). It was concluded that the estrous of the Damascus goats during the breeding season could be synchronized succesfully by the short or long term application of the FGA sponges and norgestomet implants with the combination of PMSG and PGF2α. No difference in the fertility parameters in the short or long term application were detected. Short term applications were found as succesful as long term applications. Therefore the short term applications were found to be more useful for the fl exiblity of the usage in the fi eld conditions.
