Fermentação ruminal e produção de metano in vitro de dietas contendo torta de algodão

Abstract: ResumoObjetivou-se avaliar o efeito da substituição da proteína do farelo de soja pela proteína da torta de algodão em dietas de bovinos de corte sobre suas frações de carboidratos e proteína, cinética de fermentação ruminal e produção de metano in vitro. A torta de algodão substituiu 0,0; 0,25; 0,5; 0,75 e 1 kg kg-1 PB da proteína do farelo de soja em dietas, todas com relação volumoso:concentrado de 60:40 e isonitrogenadas. Foi utilizada a técnica in vitro de produção cumulativa de gases. Os níveis de substi… Show more

“…Within the first 12 h after incubation, there was lower CH 4 production for both straws evaluated, as this period includes the lag-time phase, in which there is no methanogenesis until the sites available for microbial attachment are saturated and these synthesize its structures and enzymes (Franco et al, 2013). The linear increase in CH 4 volume for high and low straw nutritional value, from 12 h until the end of the incubation period, was associated with the slowly digestible fraction fermentation and, consequently, with acetic and butyric acid production (Getachew et al, 2005;Lee et al, 2011).…”
