Does grass provide protein

Nutrients in the soil contain small amounts of Nitrogen and since cattle eat grass they absorb the protein (in the form of nitrogen molecules) that is found in the grass or other legumes. A lot of cattle farmers and feedlots feed their cattle a dry feed they purchase that is a high protein mixture. Most cattle farmers supply their livestock with a protein content between 10 and 16 percent. Some feed can contain even higher amounts of protein.
