Previous research has shown that the protein content of swine diets can be reduced approximately two percent if the diet is supplemented with lysine and if the diet is not deficient in other amino acids. Corn-soybean meal diets that are reduced more than two percent in protein may become deficient in the amino acid tryptophan. Oats contains more lysine and tryptophan but less energy than corn. However, dietary levels of 20 to 30% oats have generally not affected pig performance. The objectives of this experiment were to evaluate the protein and lysine needs of growing-finishing pigs and to determine the value of oats as an amino acid source in low protein diets containing 20% oats as a replacement for corn.
