In vitro, Non forage, Nutritive value


Six non forage high fibrous tropical feedstuffs were used to evaluate their nutritive value using an in vitro gas production technique. The rumen mixed microbe inoculums were taken from 2
fistulated Brahman-Thai native crossbred steers. The treatments were 1) palm meal (mech-extd), 2) palm meal (solv-extd), 3) leucaena meal (leaf and stem), 4) coconut meal (mech-extd), 5) mung bean meal and 6) dried brewers grain. The treatments were assigned to a completely randomized design. The results indicated that the soluble gas fraction (a; -7.91, -24.06, -2.11, -28.96, -10.31 and -4.35 ml, respectively), fermentation of the insoluble fraction (b; 99.33, 124.06, 70.90, 128.96, 110.31 and 99.33 ml, respectively), rate of gas production (c; 0.054, 0.071, 0.047, 0.122, 0.050 and 0.045 %/h, respectively) and potential extent of gas production (a+b; 107.26, 148.13, 73.02, 157.93, 120.62 and 103.82 ml, respectively) were significantly different (P < 0.01) among treatments. The cumulative gas volume at 24, 48 and 96 h after incubation were significantly different (P < 0.01). These results suggested that coconut meal (mech-extd), palm meal (solv-extd), mung bean meal, palm meal (mech-extd) and dried brewer grain exhibit high fermentability in the rumen while luecaena meal has the lowest value.
