The voluntary feed intake and digestibility of ruminants are contingent upon the quality of the pasture, which in turn has an impact on their productivity. There is limited research on the proximate/chemical composition, in-vitro gas production and degradability of mixtures containing Megathyrsus maximus (MM) and Gliricidia sepium (GS). The study investigated the impact of different combinations of MM and GS on in-vitro gas generation, degradability and chemical composition. MM and GS were combined as follows: T1- 100%MM + 0%GS, T2- 75%MM + 25%GS, T3- 50%MM + 50%GS, T4- 25%MM + 75%GS, and T5- 0%MM + 100%GS. The treatments were assayed using standard procedures. The proximate composition of the treatments was also determined using standard procedures. Data were analyzed using descriptive statistics and ANOVA at α0.05. Initial gas produced in T1 and T2 and net gas volume (NGV) observed in T1 and T2 was significantly lower compared to other treatments. In addition, the CO2 gas produced in T3, T4 and T5 were significantly higher compared to T1 and T2. However, T1 had the lowest CO2 gas production. T5 had the highest methane (CH4) production followed by T4 and T3. T1 and T2 had the lowest CH4 production. In terms of degradability, it was observed that T5 had significantly higher organic matter degradability (OMD) compared to other dietary treatments. The crude protein observed in T5 was also significantly higher than other treatments. In conclusion, mixtures with a high content of soluble carbohydrates presented the lowest gas production. A mixture of 75% Megathyrsus maximus and 25% Gliricidia sepium is recommended for increased carbohydrate, ash, lower moisture content and methane reduction.
