Produksi Gas pada Ransum Domba Berbasis Rumput Gajah cv Mott dan Leguminosa Pohon

Abstract

Abstrak Penelitian bertujuan untuk mengetahui produksi gas pada ransum domba berbasis rumput Gajah cv Mott dan leguminosa pohon. Metode yang digunakan adalah eksperimental dengan rancangan acak lengkap (RAL) dan menggunakan uji lanjut Duncan. Terdapat empat perlakuan ransum dan lima ulangan. Perlakuan teridiri atas: R1 = 70% rumput Gajah cv. Mott + 30% gamal, R2 = 70% rumput Gajah cv. Mott + 30% lamtoro, R3 = 70% rumput Gajah cv. Mott + 30% kaliandra dan R4 = 70% rumput Gajah cv. Mott + 30% indigofera. Hasil analisis statistik menunjukkan bahwa pemberian berbagai leguminosa pohon mempengaruhi produksi gas total. Produksi gas total tertinggi diperoleh dari ransum mengandung indigofera (211,25 mL) dan lamtoro (208,06 mL). Kesimpulan menunjukkan bahwa indigofera maupun lamtoro merupakan leguminosa pohon terbaik sebagai pakan pelengkap pada ransum domba. Abstract The aim of the study was to determine gas production in sheep ration based Elephant grass cv Mott and tree legume. The method used was an experimental completely randomized design (CRD) and Duncan's test for further test. There were four ration treatments and five replications. The treatments consisted of: R1 = 70% Napier grass cv. Mott + 30% Gliricidia sepium; R2 = 70% Napier grass cv. Mott + 30% Leucaena leucocephala; R3 = 70% Napier grass cv. Mott + 30% Calliandra calothyrsus; and R4 = 70% Napier grass cv. Mott + 30% Indigofera sp. The results of statistical analysis showed that the application of various tree legumes affected the total gas production. The highest total gas production was obtained from rations containing indigofera (211.25 mL) and Leucaena leucocephala (208.06 mL). The conclusion showed that both indigofera and Leucaena leucocephala were the best tree legumes as complementary feed in sheep rations.
