Pengaruh Porositas Kantong Terhadap Degradasi Hijauan Secara In Sacco

Abstract

Pengukuran degradasi suatu bahan pakan di dalam rumen sapi berfistula atau in sacco merupakan suatu metode pendugaan kecernaan menggunakan kantong nilon. Hingga saat ini, kantong nilon yang digunakan masih impor dan mahal. Penelitian ini bertujuan mengidentifikasi bahan kain nilon di Indonesia (lokal) yang dapat digunakan sebagai bahan kantong pengganti kantong nilon impor. Sebanyak 5 jenis kantong nilon lokal (Taffeta, Abutai, N57, M100 dan Organza) dengan pembanding kantong nilon impor (Ankom), diukur porositas untuk mengukur degradasi bahan kering (DBK) dan degradasi bahan organik (DBO) rumput gajah dengan waktu inkubasi 0, 3, 6, 12, 24, 48 dan 72 jam di dalam rumen sapi perah berfistula. Penelitian ini menggunakan rancangan acak kelompok dengan menggunakan 4 frekuensi inkubasi di dalam rumen sebagai kelompok. Hasil penelitian menunjukkan bahwa porositas dan degradasi antar kantong berbeda nyata. Taffeta dan Abutai memiliki porositas, degradasi, dan laju rumput gajah yang terdegradasi baik DBK maupun DBO mendekati Ankom. Dari penelitian ini dapat disimpulkan bahwa kantong nilon produk lokal Taffeta dan Abutai dapat digunakan sebagai pengganti kantong nilon impor (Ankom) dalam penelitian in sacco.

Measuring the degradation of a feed ingredient in the rumen of fistulous cattle or in sacco is a method of predicting digestibility using nylon bags. Until now, the nylon bags used are still imported and expensive. This study aims to identify nylon fabrics in Indonesia (locally) that can be used as a substitute for imported. nylon bags by measuring the porosity and degradation of elephant grass. A total of 5 types of local nylon bags (Taffeta, Abutai, N57, M100 and Organza) with comparison of imported nylon bags (Ankom), their porosity was measured to measure dry matter degradation (DMD) and organic matter degradation (OMD) of elephant grass with time incubation 0, 3, 6, 12, 24, 48 and 72 hours in the rumen of a fistulous dairy cow. This study used a randomized block design using 4 incubation frequencies in the rumen as a group. The results showed that the porosity and degradation between bags were significantly different. Taffeta and Abutai have porosity, degradation and the rate of degraded elephant grass both DMD and OMD similar Ankom. From this research, it can be concluded that the nylon bag import (Ankom) has been used for research, can be used to replace the nylon bags local brand Taffeta and Abutai.
