Performance of finishing steers offered magnesium-mica in the feedlot ration

Coffey, K.P.; Brazle, F.K.
Forty-eight mixed-breed steers from two

sources were used in a 141-day feedlot study to

compare a control ration (C) with a ration

containing magnesium-mica (MM; 9 lb/ton).

No diet cattle source interactions were

detected. Steer gain, efficiency, and cost of gain

did not differ (P>.10) between diets. Marbling

score tended (P<.10) to be greater and the

percentage of cattle grading USDA Choice and

net carcass value were greater (P<.05) for steers

fed MM. Feeding MM in a feedlot ration may

have a substantial economic impact on feedlot

cattle.
