Pengaruh Lama Implan CIDR (Controlled Internal Drug Released) terhadap Perubahan Ukuran Vulva Kambing Peranakan Etawah

Abstract

One of the estrus responses in livestock can be observed through the vulva, including through changes in the size of the vulva. This study aims to determine the effect of CIDR (Controlled Internal Drug Released) implant duration on changes in vulva size of Etawah Crossbreed goats. The study used an experimental method with a completely randomized design (CRD) with 3 types of treatment (P1 = CIDR implant for 10 days, P2 = CIDR implant for 12 days, P3 = CIDR implant for 14 days) with 6 replications. The parameters measured were the width and length of the vulva. The results of the descriptive analysis of the percentage of estrus showed that all livestock from various treatments experienced estrus. The results of the analysis of changes in the size of the vulvar cleft on day 1, day 2, and day 3 using the orthogonal polynomial test showed that there was no significant change on day 1 and day 2 between treatments, but there was a significant change on day-3. Based on the results of the study, it can be concluded that the length of the CIDR implant has a significant effect on changes in the size of the vulvar cleft.
