[Dependence of intestinal excretion of amino acids on the amino acid content of animal feed. 2. Intestinal excretion of amino acids feeding soybean oil meal].
In an experiment with 20 15N-labelled growing rats the excretion of amino acids and the excretion of metabolic faecal amino acids were investigated after the feeding of soybean oil meal as sole protein source. A low, yet statistically significant increase of the excretion of amino acids and metabolic faecal amino acids was ascertained in accordance with a growing quota of soybean oil meal in the ration. The true digestibility of amino acids ascertained according to conventional methods is above 90% and, under consideration of the increase of metabolic faecal amino acids, on average increases by 3.5 digestibility units (1.4 to 6.2).
