Abstract:
Eleven energy feed sources were evaluated for nutritive
value by in vitro gas production technique. The rumen mixed microbe
inoculums source was taken from fistulated Brahman-Thai native crossbred
steers. The energy feed source were 1) broken rice 2) paddy rice 3) corn
meal 4) rice bran 5) rice pollard 6) rice bran oil relate 7) cassava chip
8) mung bean meal 9) tomato pomace 10) soybean hull and 11) peanut hull.
The treatments were assigned to randomize completely block design (blocked
by source feedstuffs). The results indicated that soluble gas fractions
(a), the fermentation of the insoluble fraction (b), rate of gas
production (c) and potential of extent of gas production (|a|+b) were
significantly different (p<0.01) among energy feed sources. The
cumulative gas volume at 24, 48 and 96 h after incubation were highly
significant difference (p<0.01) and estimated Metabolizable Energy (ME)
were; 6.42, 5.37, 5.91, 6.68, 4.46, 6.59, 7.42, 5.24, 4.89, 6.18 and 4.48
MJ kg-1 DM, respectively. Cassava chip exhibited the greatest
gas production characteristics, gas volume and estimated metabolizable
energy. These results suggested that because cassava chip is available
locally and inexpensive, it is the best potential energy source for beef
and dairy cattle.
