Abstract
Penelitian tentang seleksi pejantan sapi PO berdasarkan nilai pemuliaannya telah dilaksanakan di kandang percobaan Loka Penelitian Sapi Potong Grati Pasuruan, pada bulan Juni sampai November 2011. Tujuan penelitian untuk memperoleh informasi peringkat keunggulan pejantan sapi PO berdasarkan nilai pemuliaan bobot badan terkoreksi umur 205 dan 365 hari. Materi yang digunakan adalah data rekording produksi sapi PO umur 205 dan 365 hari dari 310 ekor, keturunan dari 27 ekor pejantan dan 163 ekor induk. Metode yang digunakan adalah studi kasus dengan menganalisis data rekording sapi PO tersebut di lokasi penelitian (tahun 2004-2010). Variabel yang diamati adalah bobot badan umur 205 dan 365 hari; yang selanjutnya dilakukan koreksi untuk keperluan estimasi nilai pemuliaannya berdasarkan saudara tiri (half-sib). Hasil penelitian menunjukkan bahwa rataan bobot badan sapi PO umur 205 hari sebesar 109,10+18,35 kg dan umur 365 hari sebesar 132,70+19,93 kg. Pejantan nomor 5 mempunyai nilai pemulian bobot badan umur 205 hari yang tertinggi; sedangkan nilai pemuliaan bobot badan umur 365 hari dimiliki pejantan nomor 12. Dari hasil uji peringkat terdapat korelasi yang nyata (P<0,01) antara peringkat pejantan berdasarkan nilai pemuliaan bobot badan umur 205 dan 365 hari. Disimpulkan bahwa pejantan nomor 5 menduduki peringkat pertama dari semua pejantan yang diuji, dengan nilai pemuliaan bobot badan umur 205 dan 365 hari masing-masing pada peringkat pertama dan ketiga. Kata kunci: nilai pemuliaan, pejantan, sapi Peranakan Ongole (PO) SIRE SELECTION BASED ON BREEDING VALUE IN PO CATTLE AT CATTLE RESEARCH CENTRE GRATI - PASURUAN Prihandini, P.W.*), L.

Veteran Malang ABSTRAK Research on sire selection based on breeding value in PO cattle was conducted from June to November 2011 in Cattle Research Station, Grati, Pasuruan. The objective of this research was to find out the ranking of sire superiority based on breeding value of 205 and 365 days corrected body weight. Materials used were 310 production records of PO cattle at 205 and 365 days of age, which resulted from 27 sires and 163 dams. Method used was case study with analyzing the data collectedfrom 2004-2010. Variables measured were body weight at 205 and 365 days of age, which then were corrected for estimating breeding value based on half-sib relationship. Results showed that mean of body weight of PO cattle at 205 and 365 days of age were 109.10+18.35 kg and 132.70+19.93 kg, respectively. The best sire for body weight at 205 days of age was sire number 5 and that at 365 days of age was sire number 12. There was significant rank correlation (P<0.01) between breeding value of body weight at 205 and that at 365 days of age. The conclusion was that sire number 5 was the best sire, with breeding value of body weight at 205 and 365 days of age at the first and third rank, respectively. Key words: breeding value, sire, PO cattle
