MANIPULASI SIKLUS BERAHI DENGAN PENGGUNAAN HORMON UNTUK EFISIENSI APLIKASI INSEMINASI BUATAN PADA KAMBING

Abstract

The aims of this study was to determine the right time for breeding after hormonal induction with the application of Artificial Insemination to increase pregnancy. The research material were 20 local goat. Estrous synchronization technique is performed using an intravaginal implant of EAZI-BREED ™ CIDR®, then injecting Pregnecol ^TM serum Gonadotrophin 400 IU intramuscularly 48 hours before the removal of EAZI-BREED ™ CIDR®. The length of intravaginal implant of EAZI-BREED ™ CIDR® is divided into two groups, 8 (A) and 16 (B) days. To analyze the hormone progesterone (P) blood samples are taken once every twelve hours to 72 hours after the removal of EAZI-BREED ™ CIDR®. Artificial insemination is done by cervical technique using frozen semen. The results of the research showed that estrous synchronization with the duration of intravaginal implant EAZI-BREED ™ CIDR® in the two groups was not significantly difference in terms of response, onset or duration of estrus. However, the percentage of pregnancy rate after insemination was different, where the pregnancy rate in group A was lower than group B (37.50 vs 50.00%).
