Abstract

Five energy feed sources were used to evaluate for nutritive value using the in vitro gas production technique. The rumen mixed microbe inoculums were taken from fistulated Brahman-Thai native crossbred steers. The energy feed source treatments were 1) corn meal, 2) cassava chip, 3) broken rice, 4) rice bran and 5) rice pollard. The treatments were assigned to completely randomize design (four replications). The results indicated that soluble gas fractions (a) (-32.39, -50.98, -34.02, -21.67 and -3.39 mL, respectively), the fermentation of the insoluble fraction (b) (132.39, 150.98, 134.02, 119.09 and 62.66 mL, respectively), rate of gas production (c) (0.12, 0.19, 0.08, 0.11 and 0.06 %/h , respectively) and potential of extent of gas production (a+b) (164.79, 201.97, 168.05, 140.76 and 66.05 mL, respectively) were significantly different (P<0.01) among energy feed sources. The cumulative gas volumes at 24, 48 and 96 h after incubation were significantly different (P<0.01). Cassava chip exhibited the greatest gas production characteristics and gas volume. These results together with its locally available at an inexpensive cost cassava chip was one of the potential energy source for beef and dairy cattle.

Abstract

Three crop residues and five roughages were selected to evaluate nutritive value using nylon bag technique. Nylon bag technique was conducted in two rumen fistulae Brahman-Thai native crossbred steers. Steers were fed 0.5% BW of concentrate and rice straw ad libitum. The treatments were 1) water hyacinth, 2) kraphanghom, 3) corn stover, 4) cassava hay, 5) sugarcane top, 6) Chinese spinach, 7) rice straw and 8) cavalcade hay. The result indicate that the rapidly soluble fraction (a) of DM OM and CP were highest in Chinese spinach (P<0.01). The lowest rapidly soluble fraction (a) of DM, OM were observed in sugarcane top (P<0.01). The potential degradable fractions (b) of OM and CP were highest (P<0.01) in cassava hay and the lowest potentially degradable fractions (b) of DM and OM were found in Chinese spinach. Degradation rate of DM, OM and CP in Chinese spinach was fastest. The slowest degradation rates of DM and OM were observed in water hyacinth, whereas the slowest degradation rate of CP was observed in rice straw. The effective degradability of DM, OM and CP were highest in Chinese spinach. Effective degradability of DM and OM were lowest in sugarcane top. Crop residue and selected roughages having nutritive value for ruminant feed ranked from the highest to the lowest were: Chinese spinach, krapanghom, cassava hay, corn stover, cavalcade hay, water hyacinth, rice straw and sugarcane top, respectively.
