Penelitian ini bertujuan untuk mengetahui pengaruh pejantan Ongole dan Brahman sebagai pejantan bangsa sedang dan Simmental sebagai pejantan bangsa besar terhadap pertumbuhan prasapih keturunannya. Penelitian ini dilakukan di Kabupaten Blora, Jawa Tengah selama tiga bulan dari bulan Juli sampai September 2000. Data bobot badan prasapih diestimasi berdasarkan lingkar dada dengan menggunakan pita ukur merk Rondo. Basil penelitian menunjukkan bahwa rata-rata dan standar error bobot badan estimasi dan rerata pertambahan bobot harian prasapih (W/A) pedet silangan Ongole sebesar 136,41 ± 47,83kg dan 1,34 ± 0,004kg, pedet silangan Brahman sebesar 131,55 ± 81,59kg dan 1,29 ± 0,008kg dan pedet silangan Simmental sebesar 156,71 ± 277,42kg dan 1,53 ± 0,026kg. Bobot badan estimasi dan rerata pertambahan bobot harian prasapih dianalisis dengan menggunakan analisis variansi model searah. Hasil analisis variansi menunjukkan bahwa bangsa pejantan berpengaruh tidak nyata terhadap bobot badan estimasi dan pertambahan bobot harian prasapih pedet silangan Ongole, Brahman dan Simmental.

This research was conducted to investigate the effect of Ongole and Brahman sires represented medium breeds and Simmental sires represented large breeds to preweaning growth of crossbred calves. This research was done from July to September 2000 in Blora. The preweaning weight were obtained by Rondo measuring tape. These results indicated that averages and standard errors of body weight estimated and preweaning growth rate per day (W/A) of Ongole Crossbred Calves were 136,41 ± 47,83kg and 1,34 ± 0,004kg, Brahman Crossbred Calves were 131,55 ± 81,59kg and 1,29 ± 0,008'kg and Simmental Crossbred Calves were 156,71 ± 277,42kg and 1,53 ± 0,026kg. Body weight estimated and preweaning growth rate per day were analyzed with analysis of variance for One Way design. The result of the analysis of variance showed that sire breeds were not significant influenced for body weight estimated and preweaning growth rate per day of Ongole Crossbred Calves, Brahman Crossbred Calves and Simmental Crossbred Calves.
