extends net.simplace.sim.model.FWSimComponent

This are the two equations to calculate Daily Methane Production in the paper of Ndungu et al 2019 Ndungu uses two equations (eq 16 and 17 in the paper): 1. DMP = DMI*20.7 Where DMP = Daily Methane Production (g /day) DMI = Dry Matter Intake (kg /day) 2. DMI= MERTotal / (GE * DMD/100))/0.81 MERTotal = Total Metabolisable Energy Reuiqrement (MJ/day) DMD = Dry Matter Digestibility (%) (IN Table 3 DMD of maize is on average 64,5% and DMD of pastuer grass is 59.5%) GE = Average Gross Energy assumed tob e 18.1 MJ/kg DM Equation 2 assumes that Gross energy of fodder is reduced by digestibility (e.g. Gross Energy * DMD = Digestible Energy) and Digestibly Energy contains on average 81% (0.81) metabolizable energy those factors have already been implemented in the fodder energy calculations
