Conteúdo: 	ABSTRACT The objective of this study was to evaluate in vitro ruminal fermentation, the production of volatile fatty acids (VFAs), methane (CH4) and carbon dioxide (CO2) and pH values and ammonia (N-NH3) from different byproducts generated in the production chain biodiesel through the use of an in vitro semiautomatic gas production technique using a statistical design with four treatments and five replications. The treatments consisted of substituting elephant grass in increasing levels, 0%, 30%, 50% and 70%, with the byproducts of Gossyypium hirsutum, Ricinus communis, Moringa oleifeira, Jatropha curcas and Helianthus annus. The Helianthus annus byproducts had the highest production of acetate and butyrate, and therefore higher production of CO2 and CH4. The Moringa oleifeira byproducts had the highest production of propionate and lower production of greenhouse gases. Cotton and sunflower byproducts have greater bioavailability of fat for animal production, but they are major producers of greenhouse gases. The moringa byproduct is the most suitable for replacing elephant grass and may contribute to the reduction of greenhouse gas emissions, and it can be used to level 70%.
