Samples of L. leucocephala, G. sepiumand P. maximum, with different gas production profiles, were used. The samples were submitted to the procedure for gas production and the volumes were determined every 3 h, in the first 30 h; then at 36; 48; 72 and 96 h. Five models were compared (two monophase and three biphase), and the parameters for better adjustment were determined. Mean squared error and the Durbin-Watson test were used as comparison criteria. It was concluded that the monophase models fall short to describe the kinetics of in vitrogas production with bovine excreta; whereas the biphase models with simple exponential components are useful. The biphase equation, where V = 0 for t < L and V = B * (1 – EXP (- C * (t - L))) for t ≥L classified as the most useful work is done with syringes. ER -
