> Your math seems to be off, 250kcal apparently yields 8.8kg difference a day.
The difference per 1000 kcal seems to be 5.15 - 1.17 = 3.98 kg. Where do you get 8.8 kg per 250 kcal? Maybe you were looking at the least-efficient beef? 8.8*4 = 35.2 kg per 1000 kcal would match the "beef (beef herd)" value.
