ABSTRAK
Bahan pakan yang baik untuk unggas dengan penambahan tepung daun katuk (Sauropus androgynous) dapat mempengaruhi bobot potong, bobot karkas dan dapat meningkatkan persentase karkas serta menurunkan kadar lemak abdominal dan kadar lemak dada. Tujuan dari penelitian ini untuk mengetahui pengaruh pemberian tepung daun katuk (sauropus androgynous) terhadap kadar lemak dan persentase karkas ayam broiler. Metode penelitian yang dilakukan adalah eksperimental disusun berdasarkan rancangan acak lengkap (RAL). Sebanyak 15 ekor sampel DOC broiler dibagi menjadi 5 perlakuan dengan 3 ulangan. Penggunaan daun katuk dalam bentuk tepung yang ditambahkan pada 1 kg pakan masing-masing kontrol, 40 g, 60 g, 80 g, dan 100 g dengan pemeliharaan selama 28 hari dan 14 hari perlakuan. Hasil dari penelitian didapatkan bahwa penambahan tepung daun katuk (Sauropus androgynous) dapat meningkatkan bobot potong, bobot karkas, setelah menurunkan kadar lemak abdominal dan kadar lemak dada pada perlakuan dengan penambahan tepung daun katuk (Sauropus androgynous) sebanyak 100 g. Hasil data pada penelitian didapatkan dari hasil pengolahan data dengan ANOVA yang dilanjutkan dengan uji Duncan saat hasil berpengaruh nyata. Pada penelitian ini dapat disimpulkan bahwa perlakuan dengan pemberian tepung daun katuk (Sauropus androgynous) ke dalam pakan mampu meningkatkan bobot potong, bobot karkas, dan persentase karkas serta dapat menurunkan lemak abdominal dan kadar lemak dada namun, tidak mampu menurunkan kadar lemak paha. Perlakuan yang paling efektif dalam menurunkan kadar lemak dada merupakan perlakuan dengan penambahan tepung daun katuk (sauropus androgynous) sebanyak 80-100 g kedalam 1 kg pakan.

A good feed ingredient for poultry with the addition of katuk leaf flour (Sauropus androgynous) can affect cutting weight, carcases weight, and can increase carcases percentage as well as reducing abdominal fat and breast fat levels. The purpose of this research was to find out the effect of giving katuk leaf flour (Sauropus androgynous) on the fat level and carcases percentage of broiler chicken. The research method used was experimental based on a complete random design (CRD). A total of 15 DOC broiler samples were divided into 5 treatments with 3 replications. The use of katuk leaves in the form of flour added to 1 kg of feed to each control, 40 grams, 60 grams, 80 grams, and 100 grams with 28 days of maintenance and 14 days of treatment. The result of this research found that the addition of katuk leaf flour (Sauropus androgynous) could increase cutting weight and carcases weight after reducing abdominal fat and chest fat levels in treatment with the addition of 100 grams of katuk leaf flour (Sauropus androgynous). The results of the data in this research were obtained from the results of data processing with ANOVA which followed by Duncan’s test when the results had a significant effect. In this research, it can be concluded that the treatment by adding katuk leaf flour (Sauropus androgynous) to the feed can increase cutting weight, carcases weight, and carcases percentage and can also reduce abdominal fat and breast fat levels but not able to reduce thigh fat levels. The most effective treatment in reducing chest fat levels was treatment with the addition of 100 grams of katuk leaf flour (Sauropus androgynous) to 1 kg of feed.
