- Abstract
The objetive of this research was to evaluate the nutritive and fermentative quality and methane emissions in corn stubble silages with nopal (Opuntia ficus-indica), for which three experimental treatments were evaluated, T1: corn fodder; T2: 75 % corn stubble + 25 % nopal; and T3: 75 % corn stubble + 25 % fermented nopal. Twenty-one microsilos (7 per treatment) were prepared in plastic containers and left to ferment for 30 days. At the end of fermentation, the chemical composition, fermentation parameters, gas production and methane (CH4) were evaluated. Dry matter (DM), crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF) contents were different among treatments (p<0.05); CP content increased 44 % with the addition of fermented cactus (T3). Ammonia nitrogen, lactic acid and volatile fatty acids values were different among treatments (p<0.05). Maximum gas production (Gmax) and CH4 concentration decreased 32 % and 49 % at T3, respectively. The addition of cactus and fermented cactus to corn stubble silage increases protein content. In addition, it reduces ruminal methane synthesis in vitro.
