Effect of Calcium and Magnesium upon Digestibility of a Ration Containing Corn Oil by Lambs

Abstract
Two digestibility trials were conducted to compare the effects of calcium carbonate, calcium chloride and magnesium carbonate in alleviating corn oil depression upon ration digestibility by lambs. Calcium carbonate and calcium chloride were equally effective in increasing digestibility of organic matter, and cellulose in a ration containing corn oil. Magnesium carbonate did not increase digestibility of organic matter or cellulose and decreased digestibility of protein. The addition of calcium increased fecal excretion of calcium, but the addition of corn oil did not. Nitrogen retention was not significantly affected by ration treatment. Copyright © 1963.
