Penelitian bertujuan untuk mengetahui kinerja induk sapi persilangan Simmental Peranakan Ongole (SIMPO) dan Peranakan Ongole (PO) periode kebuntingan tujuh bulan sampai kembali bunting di peternakan rakyat kecamatan Bambanglipuro kabupaten Bantul Daerah Istimewa Yogyakarta. Materi yang digunakan 18 induk SIMPO dan 20 induk PO dengan kondisi bunting tujuh bulan. Variabel yang diamati perubahan bobot badan induk selama penelitian, skor beranak, skor perinatal, postpartum anestrus (PPA), service per conception (S/C), conception rate (CR), calving interval (CI), bobot lahir, pertambahan bobot badan harian (PBBH) pedet, konsumsi bahan kering (BK), protein kasar (PK) dan total digestible nutrients (TDN). Data pertambahan bobot badan induk, bobot badan induk sehabis beranak, bobot lahir pedet, lama kebuntingan, PPA, S/C, CI dan konsumsi BK, PK dan TDN dianalisis dengan uji t sedangkan CR dengan uji Chi-Square. Hasil penelitian menunjukkan bahwa perubahan bobot badan induk sebelum beranak berbeda tidak nyata dan bobot badan induk saat beranak induk SIMPO vs PO (463,70 ± 47,29 kg vs 349,90 ± 63,34 kg) berbeda sangat nyata (P<0,01). Lama kebuntingan, PPA, CI, S/C, CR menunjukkan perbedaan yang tidak nyata. Bobot lahir pedet SIMPO vs PO (37,47 ± 5,03 kg vs 32,17 ± 4,08 kg) dan PBBH pedet SIMPO vs pedet PO (1,04 ± 0,30 kg/ekor/hari vs 0,72 ± 0,15 kg/ekor/hari) menunjukkan perbedaan sangat nyata (P<0,01). Konsumsi BK kebuntingan bulan ke 7 induk SIMPO lebih rendah daripada induk PO (P<0,05), kebuntingan bulan ke 8 induk SIMPO lebih rendah daripada induk PO (P<0,01), konsumsi PK sebelum beranak berebeda tidak nyata dan konsumsi TDN kebuntingan bulan ke 8 induk SIMPO lebih rendah daripada induk PO (P<0,05), konsumsi BK, PK dan TDN setelah beranak berbeda tidak nyata. Kesimpulan dari penelitian yaitu kinerja induk SIMPO lebih baik daripada PO dalam hal bobot badan dan PBBH pedet yang dihasilkan.

Aim of this study was to find out the performance of Simmental Ongole crossbred (SIMPO) and Ongole crossbred (PO) cows from seven months of pregnancy to four months after parturition in farming system Bambanglipuro district, Bantul sub-province. Using 18 SIMPO and 20 PO cows as seven months of pregnancy condition. The variables observed were cows body weight, score perinatal, score vigor, postpartum anestrus (PPA), service per conception (S/C), conception rate (CR), calving interval (CI), birth weight, growth of calf, dry matter (DM), crude protein (CP) and total digestible nutrients (TDN) intake. The data on gain weight of the cows, body weight at parturition, birth weight of calf, length of pregnancy, PPA, S/C, CI and DM, CP and TDN intake were analyzed using t test while CR were analyzed using Chi-Square. The result of the study showed that SIMPO body weight was higher (P<0.01) than PO (463.70 ± 47.29 kg vs 349.90 ± 63.34 kg) but average daily gain (ADG) before parturition did not differ significantly. Length of gestation, PPA, CI, S/C and CR did not differ significantly. Birth weight calf of SIMPO was higher (P<0.01) than PO (37.47 ± 5.03 kg vs32.17 ± 4.08 kg), ADG of calf SIMPO was higher (P<0.01) than PO (1.04 ± 0.30 kg/head/day vs 0.72 ± 0.15 kg/head/day). DM intake SIMPO was lower (P<0,05) than PO in 7th months of pregnancy and 8th months of pregnancy (P<0,01), CP intake prepartum did not differ significantly and TDN intake, SIMPO was lower (P<0,05) than PO in 8th of pregnancy. DM, CP and TDN intake after parturition, did not differ significantly. The conclusion of this study was the performance of SIMPO better than PO in the case of body weight and ADG of calves
