Penelitian ini dilaksanakan selama 35 hari di Farm Fakultas Peternakan Universitas Udayana Bukit Jimbaran. Rancangan yang digunakan rancangan acak lengkap (RAL) yang terdiri dari 4 perlakuan dan 6 ulangan. Tiap petak percobaan diisi dengan 5 ekor ayam broiler umur 7 hari dengan berat badan homogen. Keempat perlakuan tersebut adalah ayam yang diberi ransum komersial tanpa minyak kalsium sebagai kontrol (A), dengan pemberian 1% minyak kalsium dalam ransum komersial (B), pemberian 2% minyak kalsium dalam ransum komersial (C), dan pemberian 3% minyak kalsium dalam ransum komersial (D). Variabel yang diamati yaitu berat karkas (g/ekor), persentase daging karkas (%), persentase tulang karkas (%), dan persentase lemak subkutan (%). Hasil penelitian menunjukan bahwa berat karkas dan persentase tulang pada ayam yang mendapat 1%, 2% dan 3% minyak kalsium tidak berbeda nyata (P>0,05) dibandingkan ayam yang tidak mendapat minyak kalsium (kontrol). Persentase daging ayam yang mendapat perlakuan minyak kalsium nyata lebih tinggi (P<0,05) dibanding kontrol, sedangkan persentase lemak subkutan nyata menurun dengan pemberian minyak kalsium dibandingkan kontrol. Dari hasil penelitian dapat disimpulkan bahwa pemberian minyak kalsium sebesar 1-3% dalam ransum komersial dapat meningkatkan persentase daging dan menurunkan kandungan lemak subkutan pada ayam broiler.

This research was carried out for 35 days at the Farm Faculty of Animal Husbandry, Udayana University, Bukit Jimbaran. The design used completely randomized design (CRD) consisting of 4 treatments and 6 replications. Each plot was filled with 5 7 day-old broiler chickens with homogeneous body weight. The four treatments are chickens fed commercial rations without calcium oil as a 202 control (A), by giving 1% of calcium oil in commercial rations (B), administering 2% of calcium oil in commercial rations (C), and administering 3% of calcium oil in commercial ration (D). The variables observed were carcass weight (g / tail), carcass meat percentage (%), carcass bone percentage (%), and percentage of subcutaneous fat (%). The results showed that carcass weight and bone percentage in chickens that received 1%, 2% and 3% calcium oil were not significantly different (P> 0.05) compared to chickens that did not get calcium oil (control). The percentage of chicken meat treated with calcium oil was significantly higher (P <0.05) compared to control, while the percentage of subcutaneous fat significantly decreased with the addition of calcium oil compared to control. From the results of the study it can be concluded that administration of calcium oil by 1-3% in commercial rations can increase the percentage of meat and reduce the content of subcutaneous fat in broiler chickens.
