Tujuan penelitian ini adalah untuk mengetahui perbedaan karakteristik reproduksi kambing Kejobong dan Jawarandu betina dewasa sebagai dasar seleksi ternak. Penelitian dilaksanakan di Kelompok Tani Ternak Ngundi Dadi Kecamatan Kejobong, Kelompok Tani Tresno Maju, dan Kelompok Tani Tunas Kencana Kecamatan Pengadegan, Kabupaten Purbalingga, Jawa Tengah pada bulan Februari - Maret 2024. Penelitian menggunakan 30 ekor kambing Kejobong dan 30 ekor kambing Jawarandu. Pengambilan sampel dilakukan secara purposive sampling dengan kriteria kambing betina yang telah beranak minimal dua kali dan mempunyai cempe prasapih berumur maksimal 60 hari. Variabel yang diteliti yaitu litter size, kidding interval, paritas, mortalitas, dan bobot prasapih. Kambing Kejobong yang telah beranak minimal dua kali mempunyai litter size tunggal 40%, kembar dua 53,33%, dan kembar tiga 6,67%, rataan kidding interval 276 ± 30,92 hari, mortalitas 8%, serta rataan bobot prasapih 5,43 ± 0,90 kg. Kambing Jawarandu yang telah beranak minimal dua kali mempunyai litter size tunggal 20%, kembar dua 70%, dan kembar tiga 10%, rataan kidding interval 258 ± 21,72 hari, mortalitas 5,36%, serta rataan bobot prasapih 6,41 ± 1,26 kg. Hasil penelitian menggunakan uji t pada variabel kidding interval dan bobot prasapih menunjukkan adanya perbedaan yang signifikan antara kambing Kejobong dan Jawarandu. Hasil penelitian menggunakan uji Chi Square pada variabel mortalitas tidak menunjukkan perbedaan antara kambing Kejobong dan Jawarandu, sedangkan pada variabel litter size dan paritas menunjukkan perbedaan. Berdasarkan hasil penelitian dapat disimpulkan bahwa karakteristik litter size, kidding interval, paritas, dan bobot prasapih pada kambing Jawarandu relatif lebih tinggi dibandingkan dengan kambing Kejobong, sedangkan karakteristik dan mortalitas kambing Kejobong dan Jawarandu relatif sama.

The aim of this research was to determine the differences in reproductive characteristics of adult female Kejobong and Jawarandu goats as a basis for livestock selection. The research was carried out at the Ngundi Dadi Livestock Farming Group, Kejobong District, the Tresno Maju Farming Group, and the Tunas Kencana Farming Group, Pengadegan District, Purbalingga Regency, Central Java in February - March 2024. The research used 30 Kejobong goats and 30 Jawarandu goats. Sampling was carried out by purposive sampling with the criteria of female goats that had given birth at least twice and had a pre-weaning crest of a maximum age of 60 days. The variables studied were litter size, kidding interval, parity, mortality and pre-weaning weight. Kejobong goats that have given birth at least twice have a single litter size of 40%, twins 53.33%, and triplets 6.67%, an average kidding interval of 276 ± 30.92 days, mortality of 8%, and an average pre-weaning weight of 5. 43 ± 0.90 kg. Jawarandu goats that have given birth at least twice have a single litter size of 20%, twins 70%, and triplets 10%, an average kidding interval of 258 ± 21.72 days, mortality of 5.36%, and an average pre-weaning weight of 6.41 ± 1.26 kg. The results of the study using the t test on the variables kidding interval and pre-weaning weight showed that there were significant differences between Kejobong and Jawarandu goats. The results of research using the Chi Square test on the mortality variable showed no difference between Kejobong and Jawarandu goats, while the litter size and parity variables showed differences. Based on the research results, it can be concluded that the characteristics of litter size, kidding interval, parity and pre-weaning weight of Jawarandu goats are relatively higher compared to Kejobong goats, while the characteristics and mortality of Kejobong and Jawarandu goats are relatively the same.
