RINGKASAN Penelit ian ini bertujuan untuk mengetahui pengaruh penggunaan tepung cacing tanah (Lumbricus rubellus) dalam ransum terhadap performan domba lokal jantan. Penelitian ini dilaksanakan di kandang Jurusan Peternakan Fakultas Pertanian Universitas Sebelas Maret Surakarta yang berlokasi di Desa Jat ikuwung, Kecamatan Gondang Rejo, Karanganyar berlangsung dari tanggal 28 Desember 2008 sampai 22 Februari 2009. Domba yang digunakan dalam penelitian ini sebanyak 12 ekor domba lokal jantan dengan rata – rata berat badan 13,82 ± 0,73 kg dengan umur ± 7 bulan, yang ditempatkan pada kandang panggung individual. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) yang terdiri dari 4 macam perlakuan dan 3 ulangan, setiap ulangan terdiri dari 1 ekor domba. Perlakuan yang diberikan adalah P0 (70% hijauan + konsent rat 30% + 0% tepung cacing tanah), P1 (70% hijauan + konsent rat 28% + 2% tepung cacing tanah), P2 (70% hijauan + konsentrat 26% + 4% tepung cacing tanah), P3 (70% hijauan + konsentrat 24% + 6% tepung cacing tanah). Pemberian pakan hijauan (rumput lapang), konsentrat (bekatul, tepung jagung, bungkil kedelai) dan penambahan tepung cacing tanah berdasarkan bahan kering (BK). Parameter yang diukur adalah performan domba lokal jantan meliput i konsumsi bahan kering pakan, pertambahan bobot badan harian, konversi pakan dan feed cost per gain. Hasil penelit ian menunjukkan bahwa rata-rata dari keempat macam perlakuan yaitu P0, P1, P2 dan P3 berturut-turut untuk konsumsi bahan kering pakan 843,59; 831,67; 867,70 dan 896,86 g per ekor per hari, pertambahan berat badan harian 60,71; 57,14; 63,10 dan 67,86 g per ekor per hari, konversi pakan 13,98, 14,64, 13,83, dan 13,22, feed cost per gain Rp 19582,66; Rp. 26310,55; Rp 30323,93; Rp 34232,22. Bahwa penggunaan tepung cacing tanah (Lumbricus rubellus) sampai taraf 6% dalam ransum berpengaruh tidak nyata (P≥0.05) terhadap konsumsi bahan kering pakan, pertambahan bobot badan harian, konversi pakan, tetapi menaikkan feed cost per gain pada domba lokal jantan. Kesimpulan dari penelitian penggunaan tepung cacing tanah (Lumbricus rubellus) t idak berpengaruh terhadap performan domba lokal jantan (konsumsi bahan kering pakan, pertambahan bobot badan harian, dan konversi pakan). Kata kunci : penggunaan, tepung cacing tanah (Lumbricus rubellus), performan, domba lokal jantan Summary This research aimed to know the effects of using worm meal (Lumbricus rubellus) on rat ion to performance of male local sheeps. This research was executed at the farm of Animal Husbandary Field, Agriculture Faculty, Sebelas Maret University that located at Jatikuwung Village, Gondangrejo District , Karanganyar took place from December 28th , 2008 unt il February 22th , 2009. Male were used in this research 12 male local sheeps with average body 13,82 ± 0,73 kg with age ± 7 month years old, that placed at individual stage cage. The treatment design was used Completely Randomized Design (CRD) one way classification that consist of four kinds of t reatment and three replicat ion, each of replicat ion consist of one male local sheeps. The treatment s were given P0 (70% forages + 30% concent rates + 0% worm meal), P1 (70% forages + 28% concent rates + 2% worm meal), P2 (70% forages + 26% concentrates + 4% worm meal), P0 (70% forages + 24% concent rates + 6% worm meal). The given of forages (field grass), concentrates (bran, corn meal, soybean meal) and the added of worm meal based on Dry Matter (DM). The parameters were measured performance of male local sheeps comprised dry mat ter intake, average daily gain, feed convertion and feed cost per gain. This research’s result was shown that average of these four treatment (P0, P1, P2, P3), for dry mat ter consumtion 843,59; 831,67; 867,70; 896,86 g/male/day, average daily gain 60,71; 57,14; 63,10; 67,86 g/male/day, feed convert ion 13,98, 14,64, 13,83, 13,22, feed cost per gain Rp 19582,66; Rp. 26310,55; Rp 30323,93; Rp 34232,22. The result of the research indicated that the used of worm meal (Lumbricus rubellus) until level of 6% in rat ion had non significant effect (P≥0,05) to dry mat ter intake, average daily gain, feed convert ion, but increased the feed cost per gain on male local sheeps. The conclusion of this research that used of worm meal (Lumbricus rubellus) was not effected the performance of male local sheeps (dry matter intake, average daily gain, feed convertion). Keyword : used, worm meal (Lumbricus rubellus ), performance, male local sheeps.
