| description | The nutritive value of six protein feed sources were determined using the nylon bag technique in rumen fistulated Brahman-Thai native crossbred steers. The steers were fed 0.5% BW of concentrate and rice straw ad libitum. Nylon bags containing 5.0 g of each feed were immersed in duplicate at each time point in the ventral rumen of each steer for 2, 4, 6, 12, 24 and 48 h. The data were fitted to the equation P = a+b (1-e-ct) and effective degradability was calculated using a theoretical rumen out flow rate of k = 0.05/h. The treatments were 1) kapok seed meal, 2) soybean meal, 3) coconut meal (solv-extd), 4) peanut meal, 5) whole cotton seed and 6) fish meal assigned according to a completely randomize design with four replications. The results indicate that the rapidly soluble fraction (a), potentially degradable fraction (b), degradation rate (c) and potential degradation (a+b) of DM, OM and CP were different among treatments (P < 0.01). Effective degradability of DM, OM and CP calculated as a percentage of the nutrient were ranked from high to low: DM degradability: soybean meal (60.96%), peanut meal (52.02%), whole cotton seed (47.35%), coconut meal (solve-extd) (42.52%), fish meal (42.37%) and kapok seed meal (24.31%); OM degradability: soybean meal (59.74%), peanut meal (52.17%), whole cotton seed (46.35%), fish meal (46.22%), coconut meal (solv-extd) (39.93%), and kapok seed meal (28.69%); CP degradability: whole cotton seed (74.17%), kapok seed meal (68.18%), fish meal (47.32%), soybean meal (46.42%), peanut meal (45.35%) and coconut meal (solv-extd) (32.61%). The data provids information on combinations of energy and protein sources with similar ruminal degradation, and thus may lead to improved feeding values for ruminants. |
