<![CDATA[ABSTRAKTujuan penelitian ini untuk mengetahui efek pemberian asam lemak terproteksi yang berasal dari hasil samping pengolahan limbah ikan terhadap performa kambing peranakan etawa dalam pertumbuhan. Penelitian dilaksanakan di kandang ternak Desa Alebo, Kabupaten Konawe Selatan dan Laboratorium Ilmu Nutrisi dan Teknologi Pakan, Fakultas Peternakan Universitas Halu Oleo, Kendari. Materi penelitian meggunakan 16 ekor kambing peranakan etawa berumur 4-6 bulan dan bobot badan 10-12 kg. Pakan yang digunakan terdiri atas hijauan dan asam lemak terproteksi (ALT) sebagai campuran garam karboksilat kering (CGKK). Rancangan penelitian adalah rancangan acak lengkap dengan 4 perlakuan dan 4 ulangan. Perlakuan terdiri atas T1= 0 g ALT; T2 = 200 g ALT; T3 = 250 g ALT, dan T4 = 300 g ALT. Variabel penelitian meliputi kosumsi pakan, pertambahan bobot badan, dan konversi pakan. Hasil penelitian menunjukkan bahwa perlakuan berpengaruh sangat nyata (P<0,01) terhadap konsumsi pakan, pertambahan bobot badan dan konversi pakan kambing peranakan Etawa fase pertumbuhan. Rataan konsumsi pakan (Kg BK/ekor/minngu) T1 = 4,58; T2 = 5,68; T3 = 6,19; dan T4 = 6,48. Rataan pertambahan bobot badan (kg/ekor/minggu) T1 = 0.43, T2 = 0.90, T3 = 1.44 dan T4 = 1.42. Rataan konversi pakan T1 = 10,63; T2 = 7,61. Disimpulkan bahwa pemberian asam lemak terproteksi (ALT) yang berasal dari hasil sampig pengolahan limbah ikan (200-300 g/ekor/hari) meningkatkan konsumsi bahan kering, pertambahan bobot badan, dan memperbaiki efisiensi konversi pakan kambing peranakan etawa fase pertumbuhan.Kata kunci: asam lemak terproteksi, kambing PE, performa,ABSTRACTThe purpose of this research was to know the effect of applying protected fatty acids originated from by-product of fish processing on performance growth phase ettawa crossbred. The study was conducted at Cattle Pen located at Alebo village, South Konawe Regency, and Laboratory of Nutrition Science and Feed Technology, Faculty of Animal Science, Halu Oleo University, Kendari. The materials used 16 Etawa crossbred aged 4-6 months and weighed 10-12 kg. The feeds were applied consist of roughage and protected fatty acid (PFA), as dry carboxylate salt mixture, DCM. The research design was Complete Randomized Design with 4 treatments and 4 repeatition. The treatments were T1= 0 g PFA; T2 = 200 g PFA; T3 = 250 g PFA; and T4 = 300 g PFA. Variable were feed intake, gain, and feed conversionl. The results of research showed that the treatments had a very significant effect (P<0.01) on the feed consumption, weekly gain, and feed conversion on the growth phase. The average feed consumption (kg dry mater/head/week) T1 = 4.58; T2 = 5.68; T3 = 6.19; and T4 = 6.48. The concluded that application of protected fatty acid (PFA), originated from by-product of fish processing (200-300 g/head/day) increased dry matter intake, weekly gain, and improved feed conversion efficiency etawa crossbred.Keywords: ettawa crossbred, performance, protected fatty acid]]>
