The In Sacco Dry Matter and Organic Matter Degradability of Four Feedstuffs

Dicky Pamungkas, R Utomo

Abstract


The degradability characteristic of four feedstuffs was examined in order to optimize the use of feedstuff to make a complete feed. Arenga waste (Aw), dried-Cassava waste (dCw), dried Leucaena leaves (dLl), and Commercial feed (Cf) as control were tested by in sacco method. The method consisted of preparation, incubation, and post-incubation. Four samples of respective stuffs were placed in nylon bag and incubated for 0, 3, 6, 9, 12, 24, 36, and 72 hours (h) in the rumen of three fistulated cows (I3 aged, female Ongole Crossbred, 250 kg of live weight). Each sample was represented by three replicates at each incubation time. The in sacco measurement using the equation of D = a + b (1-ect). The value of fraction a, b and c were used to calculate the Effective Degradability (ED) with assumption that the outflow of feed particle size of rumen (Kp) was constantly at 0.06. The data were analyzed by completely randomised design. Results revealed within 24 h incubation, the dry matter degradability (DMD) of dCw (79.50%) and Cf (70.68%) were higher than that of Aw (48.84%) and dLl (54.44%). Within 3-12 h of interval incubation, all materials were the same condition in the rate of loss dry matter with ranged 0.81 to 1.25 per h and tended to decrease after 24-72 h interval incubation. Meanwhile the dry matter ED 0.06 of Aw (33.08%) was the lowest and Cf (59.99%) was the highest. As of 24 h incubation, the organic matter degradability (OMD) of dCw (62.97%) and Cf (64.37%) were higher than that of Aw (37.59%) and dLl (45.09%). Within 24-72 h of interval incubation, all materials were the same condition in the rate of loss organic matter with ranged 0.09 to 0.18% per h. The organic matter TD 0.06 of Cf (62.28%) was the highest followed by dCw (46.58%), dLl (42.44%), and Aw (25.45%). It can be concluded that the effective dry matter degradability of dried-Cassava waste (dCw), dried-Leucaena leaves was lower than commercial feed (Cf, P>0.05) but they were higher than that of Arenga waste (Aw). This condition was also alike with their effective organic matter degradability
