Penelitian ini bertujuan untuk mengetahui nilai heritabilitas litter size, jumlah anak sapihan dan berat sapih babi di CV. Adhi Farm, Karanganyar. Penelitian ini dilaksanakan pada bulan Februari 2014 sampai April 2014. Materi yang digunakan dalam penelitian ini adalah data silsilah dan data catatan meliputi catatan litter size, jumlah anak sapihan dan berat sapih babi yang berasal dari 6 ekor pejantan yang mengawini induk dengan jumlah yang berbeda-beda. Estimasi nilai heritabilitas litter size dan jumlah anak sapihan babi menggunakan data saudara tiri sebapak (Paternal Halfsib Correlation) dengan pemisahan komponen ragam rancangan acak lengkap pola searah (Completely Randomized Design One-way Classification). Estimasi nilai heritabilitas berat sapih babi menggunakan data saudara tiri sebapak (Paternal Halfsib Correlation) dengan pemisahan komponen ragam rancangan acak lengkap pola searah (Completely Randomized Design One-way Classification). Estimasi nilai heritabilitas berat sapih babi menggunakan data saudara kandung (Fullsib Correlation) dengan pemisahan komponen ragam menggunakan analisa sidik ragam rancangan acak lengkap pola searah (Completely Randomized Design One-way Classification) dan analisa sidik ragam rancangan acak lengkap pola tersarang (Completely Randomized Nested Design). Estimasi nilai heritabilitas litter size babi tergolong rendah yaitu 0,10 ± 0,11. Estimasi nilai heritabilitas jumlah anak sapihan babi tergolong rendah yaitu 0,05 ± 0,08. Estimasi nilai heritabiltas berat sapih babi Estimasi nilai heritabilitas berat sapih babi di CV. Adhi Farm menggunakan data saudara tiri sebapak adalah 0,58 ± 0,38. Estimasi nilai heritabilitas berat sapih babi menggunakan data saudara kandung dengan analisa sidik ragam rancangan acak lengkap pola searah adalah 0,55 ± 0,22, sedangkan dengan analisa sidik ragam rancangan acak lengkap pola tersarang adalah 0,66 (h2S), 0,74 (h2D) dan 0,70 (h2S+D). Nilai pewarisan sifat berat sapih babi tergolong tinggi.

This research aimed to determine the heritability for litter size, number of weaned and weaned weight of pig at CV. Adhi Farm, Karanganyar. This research was done from Februari 2014 to April 2014. The material used in this study were lineage data and recording data included litter size, number of weaned and weight weaned of pig from six sires mated dams with unequal number. Estimated of heritability for litter size and number of weaned used Paternal Halfsib Correlation. Separation of variances used Completely Randomized Design One-way Classification analysis. Estimated of heritability for weaned weight of pig used Paternal Correlation. Separation of variances used Completely Randomized Design One-way. Estimated of heritability for weaned weight of pig used Fullsib Correlation. Separation of variances used Completely Randomized Design One-way Classification and Completely Randomized Design Nested Design analysis. Estimated of heritability for litter size was classified to low with value 0,10 ± 0,11. Estimated of heritability for number of weaned pig was claasified to low with value 0,05 ± 0,08. Estimated of heritability for weaned weight used Paternal Halfsib Correlation was 0,58 ± 0,38. Estimated of heritability for weaned weight used Halfsib Correlation with Completley Randomized Design One-way Classification analysis was 0,55 ± 0,22 though with Completely Randomized Nested Design analysis were 0,66 (h2S), 0,74 (h2D) and 0,70 (h2S+D). The heritability of weaned weight was classified to high.
