Abstract: Using the artificial rumen fermentation model, this project studies the associative effects of chemically treated spent mushroom (Hypsizygus marmorens) substrate and hybrid penisetum, the combination ratios of which were 0:100 (SMS0), 15:85 (SMS15), 30:70 (SMS30), 45:55 (SMS45) and 60:40 (SMS60). In addition, the in vitro Gas production (GAS), pH, In Vitro Organic Matter Digestibility (IVOMD), Microbial Crude Protein (MCP) and Total Volatile Fatty Acids (TVFA) generation at the 6, 12, 24, 48 and 72 h and associative effects composite index (MFAEI) were determined. The results showed the following: the MFAEI of SMS15 and SMS30 were positive and compared with the control, their in vitro gas production, MCP and TVFA increased by 3.22% (p>0.05), 27.05% (p<0.01), 10.68% (p<0.05) and 1.74% (p>0.05), 12.33% (p<0.05), 7.75% (p>0.05), respectively. There was a tendency of increasing IVOMD but the difference was not significant. The MFAEI of the remaining portfolios were negative. The results indicate that the optimal ratio of chemically treated spent mushroom (Hypsizygus marmorens) substrate combined with hybrid penisetum could significantly improve the overall level of fermentation of the mixed forage.
