Penelitian ini dilaksanakan untuk mengetahui adanya pengaruh bangsa sapi potong terhadap kinerja reproduksi induk di Kabupaten Blitar Propinsi Jawa Timur, dengan menggunakan metode survei diambil dari 4 kecamatan (Talun, Srengat, Ponggok, Udanawu) meliputi 150 peternak sebagai responden. Pelaksanaan penelitian dimulai bulan Oktober sampai Nopember 2013. Variabel yang diamati meliputi identitas responden, pengalaman beternak, umur pertama kali dikawinkan, umur sapih, post partum estrus, post partum mating, service per conception, conception rate, non return rate dan calving interval. Semua data ditabulasi dan dilanjutkan dengan menghitung rata-rata, simpang baku (standar deviasi) dan persentasenya. Data kinerja reproduksi meliputi pertama kawin, serice per conception, post partum mating dan calving interval dianalisis statistik dengan menggunakan Rancangan Acak Lengkap (RAL) pola searah. Hasil penelitian menunjukkan bahwa rata-rata induk sapi potong jenis PO, SIMPO, LIMPO dan BX secara berurutan memiliki umur pertama kawin (bulan) meliputi 23,82±4,3, 24,36±5,06, 19,18±3,75, 21,85±4,13; post partum estrus (bulan) 2,71±0,66, 2,96±0,73, 2,68±0,63, 2,71±0,84; post partum mating (bulan) 5,36±1,85, 4,69±1,71, 4,3±1,71 dan 5±2,71; service per conception (kali) 1,68±0,603, 2,2±0,96, 1,65±1,01, 1,61±0,49; non-return rate (%) 40,20, 26,50, 30,62, 40,36; conception rate (%) 37,93, 25, 28,89, 38,09; umur sapih (bulan) 6,13±1,05, 5,75±1,27, 6,29±1,42 dan 6,52±1,96; calving interval (bulan) 15,15±1,96, 15,17±1,95, 14,34±1,98, 14,76±2,85;. Hasil analisis statistik menunjukkan bahwa tidak ada perbedaan yang nyata diantara keempat bangsa. Disimpulkan bahwa perbedaan bangsa sapi potong tidak berpengaruh terhadap kinerja reproduksi induk di Kabupaten Blitar.

The aim of this research was to determine the effect of cows breed in performance at small-holder cattle farm in 4 regions from 150 respondent in Blitar, such as Talun, Srengat, Ponggok and Udanawu regency. The research was conducted in October 2013. This research was carried out by survey method to get primary and secondary data. The variables were respondent’s identity, respondent’s experience, first age mating, first mating age, post partum mating, post partum estrus, service per conception, conception rate, non return rate and calving interval. The data was tabulated and counted for average, standard deviation and percentage. The data was analyzed by a Completely Radomized Design (CRD) One Way Classification and if the result is significant its continue with Duncan test. The result showed that average of maerial performance PO, SIMPO, LIMPO and BX manner to fist mating age (month) 23.82±4.3, 24.36±5.06, 19.18±3.75, 21.85±4.13; post partum estrus (mounth) 2.71±0.66, 2.96±0.73, 2.68±0.63, 2.71±0.84; post partum matting (month) 5.36±1.85, 4.69±1.71, 4.3±1.71 and 5±2.71; service per conception 1.68±0.,603, 2.2±0.96, 1.65±1.01 and 1.61±0.49; calving interval (month) 15.15±1.96, 15.17±1.95, 14.34±1.98, 14.76±2.85; the age of wean 6.13±1.05, 5.75±1.27, 6.29±1.42 and 6.52±1.96. statistical analysis showed that there were no significant differences amongst breeds. It is concluded that differences amongst beef cattle breeds did not influence to reproduction performance of cow in Blitar Regency.
