Utilizing corn fodder residue for livestock to graze to meet their nutritional needs is a less expensive option than buying or utilizing your own stored forages. Crop residue can provide an inexpensive feed source for 65-111 days into the winter. Beef cattle can successfully graze corn residue through 4 to 6 inches of snow cover. The cows will not be able to graze stalk field that get covered in ice.
When grazing residue, the livestock will be selective grazers, first eating the grain they can find followed by husks and leaves, leaving the cobs and stalks for last. Under normal conditions there is about 1 bushel of grain per acre in the field. Increased grain can be present when there is excessive header losses or the crop goes down due to weather conditions. Excessive amounts of grain present or piles do to an equipment break down can cause grain overload that could result in bloat or death in livestock. Typically, this is not a problem unless there is more than 8-10 bushels per acre of corn on the ground. When the cows are able to graze husks, leaves, and a very small amount of grain they are able to consume a diet consisting of 52 to 55 percent total digestible nutrients (TDN) and a 5-5.5 percent crude protein diet.
Stocking density and grazing method greatly effects the Continue reading Meeting Nutritional Needs with Grazed Corn Fodder
