Use of in vitro gas production to evaluate associative effects on gas production of rice straw supplemented with lucerne

摘要：

A semi-automated in vitro gas production (GP) system was used to investigate the associative effects on GP of rice straw (RS) supplemented with 0, 20,40,60, 80 and 100％ lucerne hay (LH). Rate of GP increased with increasing levels of LH (P＜0.05). Potential GP values were also affected by LH levels in the substrates, but only some significant effects were observed (P＜0.05). The associative effects were maximal at 24 h incubation and then declined with duration of incubation at all inclusion levels of LH. Supplementation with 40-60％ of LH to RS could produce the optimal associative effects on GP.
