Lemuru fish oil (Sardinella lemuru) is a rich source of omega-3 fatty acids and has potential as a feed supplement for poultry due to its unsaturated fat content, which supports metabolism and immune function. This study aimed to evaluate the effect of adding lemuru fish oil to the feed on the physical carcass composition of Joper chickens (Jowo Super). The study was conducted over two months at the Sesetan Farm, Denpasar, using a completely randomized design (CRD) with four treatments and five replications. The treatments included P0 (control), P1 (2% oil), P2 (4% oil), and P3 (6% oil). Observed parameters were slaughter weight, carcass weight, and the percentages of carcass, meat, bone, and fat. The results showed that 2% and 4% lemuru fish oil significantly increased slaughter and carcass weights (P<0.05) compared to the control, while the 6% level caused a decrease. The highest fat percentage was found in P2, but meat, bone, and carcass percentages showed no significant differences among treatments (P>0.05). It can be concluded that 4% lemuru fish oil in the feed improves slaughter weight, carcass weight, and carcass fat percentage without affecting meat and bone composition. ABSTRAK Minyak ikan lemuru sebagai salah satu sumber asam lemak omega-3 merupakan bahan pakan tambahan yang potensial, karena memiliki kandungan lemak tak jenuh yang bermanfaat bagi metabolisme dan sistem kekebalan tubuh ayam. Penelitian ini bertujuan untuk mengevaluasi pengaruh penggunaan minyak ikan lemuru (Sardinella lemuru) dalam pakan terhadap komposisi fisik karkas ayam kampung Joper (Jowo Super). Penelitian ini menggunakan metode eksperimental dengan rancangan acak lengkap (RAL), di mana ayam kampung Joper dibagi ke dalam 20 kandang, dengan 4 perlakuan dan 5 ulangan, setiap petak kandang disi 5 ekor ayam kampung jopper yang dilaksanakan di Farm Sesetan, Denpasar Bali selama 2 bulan. Perlakuan yang diberikan P0 tanpa menggunakan minyak ikan lemuru, P1 dengan menggunakan 2% minyak ikan lemuru, P2 dengan menggunakan 4% minyak ikan lemuru, dan P3 dengan menggunakan 6% minyak ikan lemuru. Parameter yang diamati meliputi bobot karkas, bobot potong, persentase karkas, persentase daging, persentase tulang dan persentase daging. Penggunaan minyak ikan dalam pakan ayam joper pada perlakuan P1, P2 dan P3 menghasilkan berat potong, berat karkas dan persentase lemak karkas lebih tinggi (P<0,05) daripada P0 (kontrol). Persentase karkas, persentase daging, dan tulang pada perlakuan P1,P2, P3 tidak berbeda nyata (P>0,05) dibandingkan P0. Dapat disimpulkan bahwa penggunaan minyak ikan lemuru 4% dalam pakan ayam joper dapat meningkatkan berat potong dan berat kaskas, dan persentase lemak karkas namun tidak berpengaruh pada persentase daging dan tulang karkas.

Efforts to accelerate the growth of native chickens aim to shorten the rearing period. Livestock practitioners in the country have innovated by crossbreeding native chickens or other superior local breeds with commercial laying hens (layers), resulting in “ayam kampung super” (in Javanese: ayam kampung jowo super/joper) whose growth rate is faster than that of ordinary native chickens. One of the poultry feed ingredients with usable energy content is fish oil. This study aimed to determine the effect of using lemuru fish oil in feed on the performance of joper chickens. The research was conducted at the Sesetan Farm, Faculty of Animal Science, Denpasar, Bali, for a period of two months. The study used a Completely Randomized Design (CRD) with four treatments, five replications, and each replication consisted of four chickens. The treatments given were: joper chickens fed a diet without fish oil (P0), joper chickens fed a diet containing 2% fish oil (P1), joper chickens fed a diet containing 4% fish oil (P2), and joper chickens fed a diet containing 6% fish oil (P3). The observed variables included initial body weight, final body weight, total feed intake, body weight gain, and Feed Conversion Ratio (FCR). The results showed that the variables of final body weight and body weight gain were significantly affected; chickens fed diets containing fish oil had higher final weights and weight gains compared to those without fish oil. Meanwhile, the use of fish oil had no significant effect (P>0.05) on initial body weight, feed intake, and Feed Conversion Ratio (FCR). Based on the results of this study, it can be concluded that adding 2% - 4% lemuru fish oil to the diet can improve the performance of joper chickens, particularly in terms of final body weight and weight gain. ABSTRAK Usaha mempercepat pertumbuhan ayam kampung, sehingga waktu pemeliharaan menjadi lebih cepat, praktisi peternakan di dalam negeri berinovasi kawin silang antara ayam kampung atau ayam lokal unggulan lainnya dengan ayam ras petelur (layer) sehingga dihasilkan ayam kampung super (Jawa : ayam kampung jowo super/joper) yang pertumbuhannya lebih cepat dibandingkan ayam kampung biasa. Salah satu pakan unggas yang memiliki kandungan energi yang dapat digunakan adalah minyak ikan. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan minyak ikan lemuru dalam pakan terhadap performa ayam kampung joper yang dilaksanakan di Farm Sesetan, Fakultas Peternakan, Denpasar, Bali selama 2 bulan. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan, 5 ulangan dan masing – masing ulangan terdiri dari 4 ekor ayam. Perlakuan yang diberikan adalah ayam joper yang diberi ransum tanpa menggunakan minyak ikan (P0), ayam joper yang diberi pakan menggunakan 2% minyak ikan (P1), ayam joper yang diberi pakan menggunakan 4% minyak ikan (P2), ayam joper yang diberi pakan menggunakan 6% minyak ikan (P3). Variabel yang diamati meliputi berat badan awal, berat badan akhir, jumlah konsumsi ransum, pertambahan berat badan, dan Feed Conversion Ratio (FCR). Hasil penelitian pada variabel bobot badan akhir dan pertambahan bobot badan menunjukan hasil yang signifikan, ayam yang diberikan pakan yang menggunakan minyak ikan lebih tinggi daripada tanpa menggunakan minyak ikan. Sedangkan pada variabel bobot badan awal, konsumsi ransum dan Feed Convension Ratio (FCR) penggunaan minyak ikan pada pakan tidak berpengaruh nyata (P>0,05). Berdasarkan hasil penelitian dapat disimpulkan ayam joper yang diberi minyak ikan lemuru 2% - 4% pada ransum mampu meningkatkan performa (bobot akhir dan pertambahan bobot badan).

This study aims to determine the effect of commercial ration substitution with shellfish shell flour and fish oil on the percentage of broiler carcass pieces. This research was carried out at Farm Sesetan, Faculty of Animal Husbandry, Udayana University which is located on Jalan Raya Sesetan, Denpasar, and lasted for 35 days. The design used was a Complete Random Design (CRD) consisting of 4 treatments and 4 replicas, each replica consisting of 4 one-day-old broilers. The treatment consisted of P0 (feed without the addition of shellfish meal and fish oil), P1 (feed with an additional 1% shellfish meal and 0.5% fish oil), P2 (feed with an additional 1% shellfish meal and 1% fish oil), and P3 (feed with an additional 1% shellfish meal and 1.5% fish oil). The variables observed included slaughter weight, the percentage of the carcass, and the percentage of pieces of the broiler carcass, namely the breast, upper thighs, drum stick, wings, and back. The data was analyzed using analysis of variance and if there were significant differences it was followed by the Duncan test. The results showed that the combination of shellfish shell flour and fish oil had a significantly effect (P<0.05) on the slaughter weight, but no significantly (P>0.05) on the percentage of carcasses and other commercial pieces. Based on the results of the study, it was concluded that the combination of 1% shellfish flour and 1% fish oil could increase sloughter weight of the broiler but not effect on the percentage of carcass pieces. ABSTRAK Penelitian ini bertujuan untuk mengetahui pengaruh substitusi ransum komersial dengan tepung kulit kerang dan minyak ikan terhadap persentase potongan karkas broiler.
