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.
