Overall, mean deviation between realized and optimized DP was
−0.28 units while the mean difference for DE was −0.56 MJ and the
mean difference between realized and optimized DE and DP varied between
the feed companies (Table 6). For Companies 1, 2, 4, and 5, the
mean difference between realized and optimized DPwas negative indicating
that the optimized values were higher than realized, and the deviation
was the least for Company 1. Company 3 had a positive mean
difference for DP indicating that optimized valueswere lower than realized.
Mean deviation between realized and optimized DE was negative
for Companies 1, 2, and 3 and the difference was most marginal for
Company 1. Companies 4 and 5 had positive deviation of DE.
