Estrus adalah kondisi betina menerima kehadiran pejantan dan siap untuk dikawini. Tujuan penelitian adalah mengetahui perubahan suhu selama periode estrus pada kuda gayo yang dipelihara secara konvensional dan non konvensional. Enam ekor kuda gayo betina dibagi dalam 2 kelompok sistem pemeliharaan (n=3). K1 dipelihara secara konvensional dan K2 secara non-konvensional. Semua kuda disinkronisasi estrus dengan teknik two shot synchronization menggunakan PGF2α secara intramuscular dengan interval 10 hari. Deteksi estrus dilakukan sehari setelah injeksi ke 2 PGF2α sampai gejala estrus berakhir. Deteksi estrus dilakukan dengan cara teasing menggunakan pejantan dan berdasarkan sistem scoring 0-4. Skor 0 menunjukkan kuda dalam keadaan tidak estrus. Skor 4 kuda dalam keadaan estrus maksimal. Pengamatan perubahan suhu sebanyak 4 kali sehari dengan interval waktu 2 jam (pukul 09.00–17.00 WIB). Pengamatan meliputi suhu rektum (termometer rektal), suhu tubuh (termometer inframerah/IRT) dan suhu lingkungan (situs BMKG). Data dianalisis menggunakan uji T. Hasil penelitian terdapat perbedaan suhu harian pada setiap individu kuda gayo pasca sinkronisasi estrus baik yang diperiksa menggunakan IRT maupun termometer rektal. Tidak ada perbedaan yang nyata terhadap nilai suhu tubuh dan suhu rektum pasca sinkronisasi estrus pada K1 dan K2 (P>0,05). Suhu lingkungan juga tidak berpengaruh terhadap perubahan suhu kuda gayo pasca sinkronisasi estrus. Kesimpulannya adalah respon individu kuda berpengaruh terhadap perubahan nilai suhu pasca sinkronisasi estrus, sementara sistem pemeliharan tidak berpengaruh terhadap perubahan suhu tubuh dan suhu rektum pasca sinkronisasi estrus pada kuda gayo baik dipelihara secara konvensional dan non konvensional.

Estrus is a when mare presence of a stallion is present and ready for mating. The purpose of this study was to determine changes in temperature during the estrus period in gayo horses with conventional and non-conventional rearing systems. Six gayo mares were divided into 2 groups of rearing system (n=3). K1 is maintained conventionally, K2 is maintained unconventionally. All mares were synchronized to estrus with a two shot synchronization technique using PGF2α by i.m at 10 day intervals. Detection of estrus was carried out the day after the second injection of PGF2α until the estrus symptoms ended. Detection of estrus by flirting with stallions. Symptoms of estrus seen based on a 0-4 scoring system. A score of 0 indicates the horse is not in heat. Score 4 mares in maximum estrus. Temperature changes 4 times a day with an interval of 2 hours starting from 09.00 WIB - 17.00 WIB. Observations included rectal temperature using a rectal thermometer, body temperature using an infrared thermometer and environmental temperature being checked with BMKG website on a smart phone. The data were analyzed using the T test. The result, there is the difference in daily temperature in each individual Gayo horse after estrus synchronization, when examined using IRT and rectal thermometers.. There was no significant difference in the values of body temperature and rectal temperature after estrus synchronization at K1 and K2 (P>0.05). Environmental temperature also has no effect on changes in the temperature of Gayo horses after estrus synchronization. The conclusion is that the horse's individual response has an effect on changes in temperature values after estrus synchronization, while the rearing system has no effect on changes in body temperature and rectal temperature after estrus synchronization in Gayo horses in conventional and non-conventional rearing system.
