Use of in Vitro Gas Production Technique to Investigate Interactions Between Rice Straw and Cassava Hay
An semi-automated in vitro gas production (GP) system was used to investigate the associative effects on GP of rice straw (RS) supplemented with 0, 25, 50, 75 and 100% cassava hay(CH).Rate of GP increased with increasing levels of CH inclusion (P < 0.05).Potential GP values were also affected by CH levels in the substrates, but only some significant effects were observed (P < 0.05).Associative effects were defined as the difference between the observed GP for the mixtures and the weighted sum of RS and CH.The associative effects were maximum at 48 h incubation and then declined with duration of incubation at all inclusion levels of CH.This study shows that 25-50% CH supplementation to RS could produce the optimal associative effects on GP.
