Daftar Isi:
- Penelitian ini bertujuan untuk mengetahui nilai ripitabilitas dan nilai MPPA bobot sapih sapi PO. Penelitian ini dilaksanakan pada tanggal 29 Juni--29 Juli 2018 di Desa Wawasan, Kecamatan Tanjungsari, Kabupaten Lampung Selatan, Provinsi Lampung. Materi penelitian yang digunakan terdiri dari umur induk pada saat melahirkan, bobot lahir pedet, umur penyapihan pedet, bobot sapih pedet, dan data rekording pada tahun 2013--2017. Penelitian ini menggunakan metode survei. Analisis data dilakukan dengan melakukan estimasi terhadap bobot sapih terkoreksi, nilai ripitabilitas, dan MPPA. Berdasarkan hasil penelitian diperoleh nilai rata-rata bobot sapih terkoreksi sebesar 111,81±13,56; nilai ripitabilitas sebesar 0,6 dan nilai rata-rata MPPA sebesar 245,98±29,83. Nilai ripitabilitas sebesar 0,6 termasuk dalam kategori tinggi. Hasil penelitian ini juga menunjukkan terdapat 56,76% sapi yang memiliki nilai MPPA diatas ratarata (245,98±29,83). Kata kunci: MPPA, sapi PO, nilai ripitabilitas, bobot sapih. ABSTRACT This research aims to estimate the value of ripitability and Most Probable Producing Ability (MPPA) for weaning weight of Ongole grade cattle. This research was carried out on 29 June--29 July 2018 in Wawasan Village, Tanjungsari District, South Lampung Regency, Lampung Province. The research material used consisted of the age of the mother at the time of delivery, calf birth weight, calf weaning age, calf weaning weight, and recording data in 2013--2017. This study used a survey method. Data analysis was carried out by estimating corrected weaning weights, ripitability values, and MPPA. Based on the results of this study the average value of corrected weaning weight was 111,81±13,56; ripitability value is 0,6 and the average value of MPPA is 245,98±29,83. Ripitability value of 0,6 estimated in this study included in the high category. This study also showed that there were 56,76% of cows which had MPPA values above the average (245,98±29,83). Keywords: MPPA, PO cattle, Ripitability estimate, Weaning weight.
