A better understanding of nutrient digestion, absorption, and metabolism is essential to improve growth rate and feed efficiency in ruminants. Absorption and metabolism of nutrients, such as glucose, lactate, and amino acids, are ones which may be affected greatly by sources and level of energy in the diet. Actual amounts of these nutrients being absorbed and available for utilization have not been characterized well in ruminants. The research being reported here describes nutrient absorption and glucose and lactate metabolism in cattle and sheep fed two basic diets, alfalfa and an 85 percent concentrate diet.
