Just another way to try and milk more money out of an unsuspecting consumer base. No cattle will be fed strictly grain. They will be fed either hay put up, or prairie grass. They need the roughage to keep their digestive tracts healthy. Straight grain would be too much on their systems and they would bloat and die.
When a steer is put in the feedlot to fatten before butcher, they will be fed both. Depending on how big they are, they will get around 2-5 gallons a day of grain, each. Which more than likely will be a mixture of wheat, barley, corn, peas, lentils, sunflower, etc... Also, different types of hay will be fed. Prairie grass, slough hay, crested wheat, barley hay, etc... They each have their different pros and cons. It usually takes a beef around 4 months of feedlot care to 'finish out'.
Another way is to feed chopped hay mixed with grains. My uncle will load around 7-8000 lbs of chopped hay, 3-400 lbs of mixed grains, then another 7-8000 lbs of water into a mixing truck. This will be fed to around 125 head or so, give or take. This is fed once every two days in the winter months, with dry hay being fed on the alternating day. Takes a lot of feed to keep a cattle herd going, especially during the winter months. And this is before moving cattle into the feedlot. He usually feeds out around a dozen or so head for butcher. The rest of the calves go to market where meat buyers will buy them and ship to a feedlot for finish.
Strange topic for a football thread. Only at the DCC.
