Peningkatan Kualitas Ampas Tebu Sebagai Pakan Ternak Melalui Fermentasi dengan Penambahan Level Tepung Sagu yang Berbeda

Abstract

Feed plays an important role in livestock production system. Due to limitation of pasture and forege areas, it needs to find new feed alternative as replacement of forage as animal feed. One of feed alternatives as replacement of forage is bagasse. Bagasse has low nutritive content and digestibility. One of the efforts to improve bagasse quality is by fermentation. The purpose of this experiment was to improve nutritive values of bagasse by fermentation method by using Trichoderma harzianum as inoculum. This research was conducted at Animal Nutrition Laboratory, Animal Husbandry Department, Agricultural Faculty, Syiah Kuala University, Banda Aceh from January to April 2015. The experiment was designed by completely randomized design (CRD) with 4 treatments (addition of sago flour at defferent levels); R 1 control (0% sago flour), R 2 (5% sago flour), R 3 (10% sago flour), R 4 (15% sago flour) of fermented material. Each treatment has 4 replications, therefore there were 16 units of treatment. Parameters observed in this experiment were nutritive values of fermented bagasse including the contents of dry matter, crude protein, crude fiber and ash. The results of the experiments indicated that fermented bagasse with Trichoderma harzianum by addition of various levels of sago flour had significantly effect (P<0, 05) on crude fiber and ash contents. However, there were not significantly difference (P>0, 05) on dry matter and crude protein contents. In conclusion, addition of various levels of sago flour by using Trichoderma harzianum at fermented bagasse was able to improve nutritive values of fermented bagasse. Keterbatasan sumber bahan pakan hijauan bagi ternak ruminansia akibat perubahan fungsi lahan perlu dicari sumber alternatif pengganti hijauan. Potensi bahan pakan ternak ternak ruminansia sebagai penganti hijauan sangat besar di Provinsi Aceh (Samadi et al., 2010). Salah satu bahan pakan alternatif sumber serat pengganti hijauan adalah hasil samping industri pertanian seperti ampas tebu. Saat ini pemanfaatan ampas tebu sebagai pakan ternak belum maksimal, karena rendahnya kualitas ampas tebu sehingga kecernaannya rendah. Menurut Pandey et al. (2000) ampas tebu mengandung lebih kurang 50% selulosa, 25 % hemiselulosa dan 25 %

The Changes of Nutrient Content of Cassava Peel (Manihot esculenta Crantz) That Fermented by Indigenous Microorganisms (IMO) As Animal Feed

“…Thus microbial worked during the fermentation process was more optimal in degrading cassava peel so that more organic matter were degraded and the ash content decreased. This was in accordance with research by [9] and [10].…”

Evaluation of Agro-Industrial by Products as Potential Local Feed for Ruminant Animals: Chemical Composition, Fiber Fractions and In Vitro Rumen Fermentation

“…Agro-industrial by products as an alternative feedstuff have been used as animal feed to reduce feed cost (Mirzaei-Aghsaghali and Maheri-Sis, 2008;Samadi et al, 2015a;Samadi et al, 2015b). Agro-industrial by products is also a potential solution to provide protein and calories for animal production in worldwide.…”

Improving Sugarcane Bagasse as Animal Feed by Ammoniation and Followed by Fermentation with Trichoderma harzianum (In Vitro Study)

“…However, agricultural and agro-industrial by product feed conteined high percentage of fiber and difficult to be digested by animals (Suwandyastuti and Rimbawanto, 2011). Researchs conducted by scientiests indicated that pre-treatment of high fiber feed were able to improve nutrient content and digestibility of feed (Bisaria et al, 1997;Tang et al, 2008;Wanapat et al, 2009 ;Rahman et al, 2011 ;Shrivastava et al, 2011 ;Wajizah et al, 2015 ;Samadi et al, 2015).…”
