Maybe 1 calorie of cow per 12 of corn, but dairy cows are much more efficient than that: Cow eats 40.57 MCAl/day [1] Produces 45.5 KGS of milk [1] Milk 610 kcal/liter Energy of cows milk per day 27.755 MCAL Cow milk efficiency 68% This feels high as a gut reaction, maybe calculation is missing energy to grow the cow. Still it shows how efficient they are! Would love a source for your cow meat efficiency numbers, I'm currently exploring efficiency of fermentation methods to produce meat alternatives and that would be a helpful data point.
