Step 1
Cattle are ruminants, meaning they have a four-compartment stomach that allows them to ferment feed. This fermentation process, carried out by microbes in the rumen, breaks down feed components, including protein. Hogs, on the other hand, are monogastric animals, Show more…

Usable protein in pounds per acre per year: Soybeans: 263 Rice: 224 Legumes (average): 94 Milk: 75 Eggs: 71 Meat (average): 36 Beef: 15.6 4. If all of your protein were coming from beef, what percentage of your acres would go to cattle grazing? 5. If all of your protein were coming from rice, what percentage of your acres would go to rice farming? 6. If all of your protein were coming from milk and eggs, estimate the acres needed for milk cows and chickens.
