Table 5.
(A) In vitro cumulative gas production, organic matter degradability, and fermentation kinetics parameters of different C. sativa extracts. OMD: organic matter degradability; OMCV: cumulative volume of gas related to incubated OM. Rmax: maximum fermentation rate; Tmax: time at which Rmax occurs. * p < 0.05, ** p < 0.01 and *** p < 0.001. NS: not significant. (B) In vitro gas production over time of C. sativa Cs/1/1 extract and its fractions Cs/2/1 and Cs/3/2 at 50-mg (●) and 200-mg (●) dose levels and control diet (●).
