DEGRADASI NUTRIEN BAHAN PAKAN LIMBAH PERTANIAN DALAM RUMEN KAMBING SECARA IN SACCO

Abstract

ABSTRAK

Penelitian ini bertujuan untuk mengkaji besarnya nilai degradabilitas nutrien antar bahan pakan limbah pertanian. Materi yang digunakan adalah bahan pakan berupa pucuk tebu, jerami padi, janggel jagung, jerami jagung dan rumput gajah serta tiga ekor kambing berfistula. Bahan pakan dikeringkan dan digiling hingga lolos saring berukuran ± 2 mm. Masing-masing sampel bahan pakan dimasukkan kedalam kantong nilon diinkubasikan ke dalam rumen ternak yang berfistula dengan interval waktu 0, 3, 6, 12, 24, 48 dan 72 jam. Residu bahan pakan yang telah diinkubasi ditimbang dan dianalisis bahan kering, bahan organik dan NDFnya. Rancangan yang digunakan adalah rancangan acak lengkap dengan 5 bahan pakan sebagai perlakuan dan 3 ulangan berupa jumlah kambing. Adanya pengaruh perlakuan bahan pakan dilanjutkan dengan Duncan multiple range test. Hasil penelitian menunjukkan adanya perbedaan nyata (p<0,05) pada fraksi a, b, c dan DT pada degradasi BK, BO dan NDF diantara pucuk tebu, jerami padi, janggel jagung, jerami jagung, dan rumput gajah. Urutan nilai DT BK, BO, dan NDF dari yang tertinggi adalah rumput gajah, jerami jagung, pucuk tebu, jerami padi dan janggel jagung.

ABSTRACT

This aim of research is to review the value of nutrient degradability of agricultural by-products. The material used is of sugar cane tops, rice straw, corn corncob, corn straw and elephant grass, and three fistulated goats. Feed material is dried and milled to pass ± 2 mm filter size. Each of the samples of feed materials put into nylon bags incubated in the rumen of goats that fistulated with interval time 0, 3, 6, 12, 24, 48 and 72 hours. Residues that have been incubated were weighed and analyzed dry matter, organic matter and neutral detergent fiber. The research design used was completely randomized design with five feeds for the treatment and 3 replications of the number of goats. Treatment of the influence of feed ingredients followed by Duncan's multiple range test. The results indicate a significant difference (p <0.05) in fractions a, b, c and DT in the degradation of BK, BO and NDF among the shoots of sugarcane, rice straw, corn corncob, corn straw and elephant grass. The order of the value of dry matter, organic matter and neutral detergent fiber of the highest are elephant grass, straw, corn, sugar cane tops, rice straw and corn corncob.
