Perbandingan performa reproduksi kambing gembrong dan kambing boerka jantan abstrak penelitian ini bertujuan mengetahui perbandingan performa reproduksi kambing gembrong dan kambing boerka. penelitian dilaksanakan di loka penelitian kambing potong sei putih, deli serdang, sumatera utara. dalam penelitian ini digunakan kambing gembrong (n=3) dan kambing boerka (n=3) jantan, berumur 3 tahun dan memiliki rata-rata skor kondisi tubuh (skt) yang sama yakni 3,83±0,29. performa reproduksi yang diamati meliputi lingkar skrotum, skor libido, dan kualitas semen secara makroskopis (volume, warna, bau, dan konsistensi) dan mikroskopis (konsentrasi, motilitas, viabilitas, dan abnormalitas). data yang terkumpul ditabulasi dan dianalisis dengan uji t. dari seluruh parameter performa reproduksi yang diperiksa, diketahui hanya parameter volume semen (ml) dan konsentrasi sperma (x106 sel/ml) menunjukkan perbedaan yang signifikan (p0,05). disimpulkan bahwa performa kambing boerka lebih baik dibandingkan kambing gembrong. kata kunci: kambing gembrong, kambing boerka, semen, libido, lingkar skrotum

COMPARISON OF REPRODUCTIVE PERFORMANCE OF GEMBRONG GOATS AND MALE BOERKA GOATS ABSTRACT This study aims to compare the reproductive performance of gembrong goats and boerka goats. The research was carried out at the Sei Putih Slaughter Goat Research Workshop, Deli Serdang, North Sumatra. In this study, male gembrong (n=3) and boerka (n=3) goats, aged 3 years and having the same average Body Condition Score (SKT), were 3.83±0.29. Reproductive performance observed included scrotal circumference, libido score, and semen quality macroscopically (volume, color, odor, and consistency) and microscopically (concentration, motility, viability, and abnormalities). The data collected was tabulated and analyzed by t test. Of all the reproductive performance parameters examined, it is known that only the parameters of semen volume (ml) and sperm concentration (x106 cells/ml) showed a significant difference (P0.05). It was concluded that reproductive performance of boerka goats were higher than gembrong goats. Key words: gembrong goats, boerka goats, semen, scrotal circumference, libido
