Pemanfaatan Limbah Berserat Dalam Konsentrat Untuk Sapi Jantan Umur Satu Tahun

Abstract

A series of experiment had been conducted to improved the quality of rice straw, rice bran and cassava solid waste through biological pretreatment using several species of microbes. Based on the digestibility and the fermentation product, indicated that 30 percent of rice straw, 35 percent of rice bran and 35 percent of cassava solid waste was the optimal ratio for concentrate formulated. The present experiment was carried out by experimental method with Completely Randomized Design, on twelve yearling male cattle of Ongole grade. The treatment tested were 3 physical form of the concentrate : (1) unfermented mesh; (2) fermented mesh and (3) fermented pellet. The variables measured were : energy and protein digestibility, rumen fermentation product, nitrogen balance and daily body weight gain. The digestion and balance trial were carried out by the Total Collection Method. The analysis of covariance shown, that there were significantly effects of the treatment tested whether upon the protein and energy digestibility, the nitrogen balance (P<0.01), nitrogen ammonia production and daily body weight gain (P<0.05), but there was no significantly effect on the Total Volatile Fatty Acid and the proportion of the individual VFA (P<0.05). Based on the all variables measured, it was indicated that fermented pellet was the best concentrate (composed by 30% of fermented rice straw, 35% of fermented rice brand and 35% of fermented cassava solid waste).

The Improvement of Rumen Fermentation Products Through In-Vitro Supplementation of Mg and Co Minerals

“…The results achieved in the current study is higher than the results of Hindratiningrum et al (2011) which is 6.67-7.82 mM. Such discrepancy may occur due to the production of N-NH3 which is highly affected by several factors, including feed, mainly depending on the composition and properties of feed protein (Suwandyastuti and Rimbawanto, 2011).…”

“…Mean VFA results of the current study were higher than 70-130 mM of normal concentration of VFA in cattle rumen (Khampa and Wanapat, 2006). Such discrepancy may occur because the VFA production depends on the chemical composition and structure of the feed materials as well as the ratioof forage and concentrate ration (Suwandyastuti and Rimbawanto, 2011). The high concentration of VFA can be used as a measure of the energy availability in the form of ATP (Suryapratama, 1999), despite the high concentration of VFA can also be due to the lack of VFA absorption of in vitro experiments.…”

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).…”

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

“…One of strategies to solve the problem was to ulilize agricultural and agro-industrial by products as animal feed. 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).…”
