Penelitian ini bertujuan untuk mengetahui perbandingan respon estrus Domba Ekor Tipis (DET) yang disinkronisasi dengan intravaginal sponges dan controlled internal drug release re-use. Empat ekor DET dengan umur lebih dari satu tahun dan belum pernah melahirkan dipelihara dengan sistem intensif. Domba diberi pakan konsentrat pada pagi hari dan hijauan pada sore hari. Domba diimplan dengan intravaginal sponges selama 12 hari dan CIDR re-use selama 13 hari. Gejala estrus diamati 7 hari berturut-turut setelah pelepasan implan. Data yang dikaji meliputi warna vulva, pembengkakan vulva, mukus vulva, jumlah langkah, nilai pH vagina, onset, dan durasi estrus. Data warna vulva, pembengkakan vulva, dan mukus vulva dianalisis menggunakan Paired Sample T-Test. Jumlah langkah, nilai pH, onset, dan durasi estrus dianalisis menggunakan Mann-Whitney Test. Hasil menunjukkan perbedaan nyata (P<0,05) pada warna vulva, pembengkakan vulva, jumlah langkah, nilai pH, onset dan durasi estrus. Hasil menunjukkan perbedaan tidak nyata (P>0,05) pada mukus vulva. Rerata hasil analisis implan sponges intravaginal dan CIDR re-use untuk warna vulva yaitu 2,25 +- 0,50 dan 3,5 +- 0,58, pembengkakan vulva 2,00 +- 0,00 dan 3,0 +- 0,82, pelepasan mukus 2,25 +- 0,50 dan 3,25 +- 0,96. Rerata jumlah langkah perlakuan intravaginal sponges saat diestrus yaitu 453,67 +- 4,51 langkah dan saat estrus 872,00 +- 4,00 langkah. Rerata jumlah langkah perlakuan CIDR re-use saat diestrus yaitu 565,64 +- 35,34 langkah dan saat estrus 1030 +- 30,92 langkah. Rerata nilai pH yaitu 8,00 +- 0,00 dan 8,83 +- 0,24. Rerata durasi estrus 21,00 +- 6,00 jam dan 36,00 +- 0,00 jam. Rerata onset estrus 45,00 +- 6,00 jam dan 24,00 +- 0,00 jam. Hasil tersebut diklarifikasi dengan pengamatan sitologi vagina dan pola ferning saliva. Disimpulkan bahwa sinkronisasi estrus menggunakan CIDR re-use lebih baik dibandingkan intravaginal sponges.

This study aimed to determine the comparison between estrus response of thin-tailed ewe (DET) synchronized in intravaginal sponge and controlled internal drug release re-use. The age of four thin-tailed were more than one year old and never been given birth and reared in an intensive system. The thin-tailed ewe were fed concentrate feed in the morning and forage in the afternoon. The thin-tailed ewe were implanted with intravaginal sponge for 12 days and CIDR re-use for 13 days. Estrus symptoms were observed in 7 consecutive days after implant removal. Data studied were vulvar color, vulvar swelling, vulvar mucus, number of steps, vaginal pH value, onset, and estrus duration. Data of vulvar color, vulvar swelling, and vulvar mucus were analyzed by using Paired Sample T-Test, while number of steps, pH value, onset, and estrus duration were analyzed by using Mann-Whitney Test. The results showed significant differences (P <0.05) in vulvar color, vulvar swelling, number of steps, pH value, onset, and estrus duration. The results showed no significant differences (P> 0.05) in vulvar mucus. The mean results of intravaginal sponge's implant and CIDR re-use for vulvar color were 2.25 +- 0.50 and 3.50 +- 0.58, vulvar swelling 2.00 +- 0.00 and 3.00 +- 0.82, vulvar mucus 2.25 +- 0.50 and 3.25 +- 0.96. The mean number of steps for intravaginal sponges treatment when diestrus was 453.67 +- 4.51 steps and 872.00 +- 4.00 steps at estrus. The mean number of CIDR re-use treatment steps when diestrus was 565.64 +- 35.34 steps and 1030 +- 30.92 steps at estrus. The mean pH values were 8.00 +- 0.00 and 8.83 +- 0.24. The mean of estrus duration was 21.00 +- 6.00 hours and 36.00 +- 0.00 hours. The mean onset of estrus was 45.00 +- 6.00 hours and 24.00 +- 0.00 hours. The results were clarified by observing vaginal cytology and salivary ferning patterns. The conclusion was estrus synchronization by using CIDR re-use better than intravaginal sponges.
