It covers determining expected daily gain, establishing DM/ME/CP of ingredients, predicting the final ration M/D, and calculating forage intake and concentrate supplementation. The chapter provides worksheet-style calculations for ME shortfall, net value of concentrate DM, daily concentrate requirement, checks for actual M/D and CP, compilation of the daily ration, and construction of a feed budget across the feeding period.","Chapter 6  \nRationing  \nThe procedure for ration formulation used here has the following steps:  \n􀁸 Set a target daily gain.  \n􀁸 Establish the DM, ME and CP contents ofthe feed ingredients.  \n􀁸 Predict the M/D of the final ration.  \n􀁸 Determine the daily ME requirement and the required CP level in the ration.  \n􀁸 Predict potential forage intake and calculate the amount of concentrate supplement required.  \n􀁸 Compile the daily ration.  \n􀁸 Draw up a feed budget for the whole feeding period.  \nThe cells are cross referenced by letters from A to AO to help users follow through the calculations.
