title: [Effect of dietary protein levels on the amount of blood free amino acids in lambs].
abstract: Growing lambs were fed increasing amounts of nitrogenous matter (12 to 20 per 100 on dry matter basis). Free amino acid and urea levels were measured in blood of 37 kg lambs. When crude protein content of diets exceeded 16 per 100, the catabolism of several essential amino acids increased. Methionine, lysine and histidine seemed to be limiting for growing lambs.
