“…Różycki (2003) proposed that result of the performance test was one of the main criteria in the selection of pig for breeding and livestock production. Some author use performance traits for the evaluation of growth ability, others use parameters from testing stations (Bečková et al, 2005;Kernerová et al, 2006;Michalska et al, 2014). Therefore, an evaluation of the livestock in advance is very important to know the conditions in which animal are kept before any definite recommendations can be made.…”

ABSTRAKPenelitian bertujuan untuk menganalisis perbedaan kemampuan genetik ternak babi dari bangsa Landrace, Yorkshire, dan Duroc dengan melakukan evaluasi terhadap produktivitas yang memiliki nilai ekonomi yang sangat penting. Ternak babi sebanyak 49 ekor yang terdiri dari 15 ekor jantan dan 34 ekor betina dengan bobot badan awal 18,50-21,50 kg dipelihara dalam kondisi lingkungan yang sama. Rancangan yang digunakan adalah Rancangan Acak Lengkap dengan perlakuan 3 bangsa (Landrace, Yorkshire, dan Duroc). Data dianalisa menggunakan analysis peragam (Ancova) dan uji Least Square Means. Hasil penelitian menunjukkan bahwa penampilan produksi bangsa Landrace, Yorkshire, dan Duroc berbeda signifikan terhadap konsumsi ransum harian, pertambahan bobot badan harian, konversi pakan, tebal lemak punggung, indeks seleksi, dan umur pada saat mencapai bobot 90 kg, kecuali konsumsi ransum harian pada jantan. Berdasarkan kondisi lingkungan pemeliharaan, Yorkshire dan Landrace memiliki potensi unggul dalam laju pertambahan bobot badan, konversi pakan, indeks seleksi, dan umur pada saat mencapai bobot 90 kg yang lebih singkat dibanding Duroc. Duroc berpotensi menghasilkan lemak punggung yang lebih tipis yang berpengaruh dalam kualitas daging dibanding Yorkshire dan Landrace. Kata-kata kunci: babi, bangsa, nilai produksi ABSTRACTThe objectives of this study was to analyze the comparative ability of animal genetic, using evaluation of production that has important economic traits including Landrace, Yorkshire, and Duroc breeds of swine. A total of 49 swine consist 15 boars and 34 gilts, with average body weight of 18.50-21.50 kg were used in this research. All of samples were raised in the same pen and feeding management. This research used the experimental method of Completely Randomized Design involving three treatments of animal breeds including Landrace, Yorkshire, and Duroc breeds. The data were analyzed by using analysis of covariance procedur General Linier Model and Least Square Means test. Boars and gilts were analyzed in separated data. The result showed that the effect of breed was significantly associated for all traits, but not for boars feed intake. The overall, Yorkshire and Landrace performed better than Duroc for average daily gain, feed conversion ratio, selection index, and age at 90 kg body weight. However, Duroc boars and gilts had the thinnest backfat followed by Yorkshire and Landrace.
