Degradation Characteristic of Tomato Pomace, Soybean Hull and Peanut Pod in the Rumen Using Nylon Bag Technique
Songsak Chumpawadee

Abstract:
Degradation characteristics of three by-product, were studied using the nylon bag technique. Nylon bags technique were conducted in two rumen fistulated Brahman-Thai native crossbred steers. They were offered ad libitum rice straw and received concentrate at 0.5% BW. Nylon bags containing 3.0 g of each by-product were immersed in duplicate at each time point in the ventral rumen of each steer for 3, 6, 12, 24, 48 and 72 h. The data were fitted to the equation P = a+b (1-e-ct) and effective degradability were calculated using a theoretical rumen out flow rate of k = 0.05/h. The treatments were 1) tomato pomace, 2) soybean hull and 3) peanut pod assigned according to a completely randomize design with four replication. 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). The effective degradability of DM, OM and CP are the same between soybean hull and peanut pot, but differences with tomato pomace. This data is necessary to screen by-product for nutritive value before using them in ruminant production systems.
