Energy Metabolism in Sheep as Influenced by Interactions among the Ration's Energy Content, Physical Form and Buffers

University of California, Davis²

Abstract

Experiments were designed to study the DE, ME and NE_M+P metabolism in sheep, as influenced by source of energy, physical form and buffers and interactions thereof. The concentrate energy source ration had a significantly higher DE, ME and NE_M+P than the roughage energy source. Nutrient digestibility and DE decreased when the roughage energy source was pelleted, but did not materially change when the concentrate energy source ration was pelleted. Increased feed intake from pelleting the roughage energy source occurred and thus increased growth and energy gain of growing fattening lambs, because of the greater intake of feed above that required for maintenance. Sodium bicarbonate fed at 5 and 12% of the ration decreased feed intake and growth, particularly when the roughage energy source ration was fed and decreased percent carcass fat to a greater extent than expected from the decreased feed intake. ME and NE_M+P was not affected by pelleting the rations or adding 5 and 12% sodium bicarbonate to the ration.
