ABSTRACT - The objective of this work was to evaluate the effect of diets with cottonseed and vitamin E on the greenhouse gas (GHG) emissions of cattle feces analyzed in biodigesters. Animal feces were evaluated in 18 laboratory-scale anaerobic digesters through the following treatments: control, feces from cows fed with a control diet; CS, feces from cows fed with a cottonseed diet; and CSVitE, feces from cows fed with a cottonseed and vitamin E diet. The production of biogas and GHG was measured, and no differences were observed for the emissions of biogas, methane (CH4), and nitrous oxide (N2O). The partition of the gross energy of the anaerobic digestion process was similar among treatments. On average, 28% of gross energy fed was released as CH4, 47% during digestion, and 25% as other gases and heat. The addition of cottonseeds to the cattle diet increases the concentration of CH4 and reduces that of CO2, but it does not affect the total production of CH4, CO2, and N2O in the biodigesters. The inclusion of vitamin E in the diet has no effect on GHG production in the biodigesters. RESUMO - O objetivo deste trabalho foi avaliar o efeito de dietas com caroço de algodão e vitamina E nas emissões de gases de efeito estufa (GEE) de fezes de bovinos analisadas em biodigestores. As fezes dos animais foram avaliadas em 18 digestores anaeróbios de laboratório, por meio dos seguintes tratamentos: controle, fezes de vacas alimentadas com dieta controle; CS, fezes de vacas alimentadas com caroço de algodão; e CSVitE, fezes de vacas alimentadas com caroço de algodão e vitamina E. As produções de biogás e GEE foram medidas, e não foram observadas diferenças para as emissões de biogás, metano (CH4) e óxido nitroso (N2O). A partição da energia bruta do processo de digestão anaeróbica foi semelhante entre os tratamentos. Em média, 28% da energia bruta alimentada foi liberada como CH4, 47% na digestão e 25% como outros gases e calor. A adição de caroços de algodão na dieta de bovinos aumenta a concentração de CH4 e reduz a de CO2, mas não afeta a produção total de CH4, CO2 e N2O nos biodigestores. A inclusão de vitamina E na dieta não tem efeito na produção de GEE nos biodigestores.

The utilization of byproducts from biodiesel production is an alternative for animal feed that allows for an increased nutritional value of the diet at a low cost and reduce green house gases (GHG). The objective of this study was to evaluate the production of volatile fatty acids (VFAs) and gases of biodiesel production byproducts in replacement of elephant grass. We used elephant grass (Pennisetum purpureum) and the following byproducts: soybean meal [SBC, Family Fabaceae (alt. Leguminosae; Glycine max)], canola cake (CC, Family Brassicaceae; Brassica napusL.), sunflower cake (SC, Family Asteraceae; Helianthus annuus), and fodder radish cake (FRC, Family Brassicaceae; Raphanus sativusL.) using an in vitrosemiautomatic gas production system and four different levels (0, 30, 50 and 70%) of elephant grass hay (EGH) replacement. The inoculum for the in vitroincuba-tion was obtained from three Holstein cows with rumen fistulas. Gas production was measured 3, 6, 12, 24 and 48 hours after incubation. The experimental design was completely randomized in a 4×4 factorial arrangement with the factors being the byproduct type and levels of inclusion in diet. Ruminal incubation using a 0.3-g sample in buffered culture medium was performed in order to determine the yield of methane (CH4), carbon dioxide (CO2) and ammoniacal nitrogen (N-NH3), as well as pH and concentration of volatile fatty acids (VFAs). The production of gas increased (p < 0.05) with increasing levels of diet substitution. The addition of different levels of byproducts influenced (p < 0.05) the production of CH4, CO2and NH3 of VFAs, and the molar concentration of acetic, propionic and butyric acids. The acetate:propionate ratio and pH were affected (p < 0.05) by the inclusion of studied byproducts. The byproducts of soybean generated greater gas production and VFAs, while the lowest yield was observed with the byproduct fodder radish in the highest level tested (70%).
