Abstract: SUMMARY The aim of the study was evaluate the production potential for methane (CH4) and carbon dioxide (CO2), short-chain fatty acids, ammonia nitrogen (N-NH3) and pH by semi-automated techniquein vitro from biodiesel byproducts cottonseed cake (Gossypium hirsutum), castor bean (Ricinus communis), moringa cake (Moringa oleifera), jatropha cake (Jatropha curcas) and sunflower cake (Helianthus annuus) substituting corn silage in increasing levels, 0, 30, 50 and 70%. The experimental design used was completely r… Show more

“…This increase may have occurred because the crushed crambe displays cationic properties (Medeiros et al 2015a;Moreira et al 2016). Oilseed cakes will increase propionate:acetate ratio by H 2 kidnap (Medeiros et al 2015b) and thus increasing the energy production from propionate (glucose þ2 H 2 ) and further reduce the production of methane (Moreira et al 2014;Morais et al 2015).…”

“…In cattle production, the high cost of concentrate feed ingredients has prompted the testing of new unconventional alternatives for inclusion in the diet. One alternative that has been widely tested is supplementation with co-products of the biofuel industry (Cerutti et al ., 2016), because the biofuel industry has created new options for ruminant production systems by generating meals and cakes as co-products of the oil extraction process (Bezerra et al ., 2015; Medeiros et al ., 2015). These co-products can be low-cost alternatives for animal feeding, replacing conventional ingredients (maize and soybean) without negatively impacting (de Gouvêa et al ., 2015; Santana Filho et al ., 2015; Costa et al ., 2016), or even increasing, weight gain and improving the quality of meat (Owaimer et al ., 2004; Shi et al ., 2014; Uchockis et al ., 2014).…”

“…When evaluating the nutritive value of oilseed crushing byproducts in lamb diets, Brás et al (2014) found 29.10 mg/dL of ammonia in crambe cake, greater than that stated in literature, but lower than the toxic concentration (100 mg/dL). However, Medeiros et al (2015a) observed in vitro ammoniacal nitrogen from a myriad of biofuel byproducts replacing maize silage and reported increasing ammonia as replacement levels were higher.…”
