The use of plasma free amino acids for predicting the limiting amino acid(s) in diets for chickens



The use of plasma free amino acids for predicting the limiting amino acid(s) in diets for chickens



Animal Feed Science and Technology 47(1/2): 151-164



In experiment 1 male broiler chickens, 23 days old, were tube-fed with a nitrogen-free diet for 4 days and then with a diet based on casein. Blood samples were taken by heart puncture for amino acid (AA) analysis at hourly intervals between 0 and 6 h after a meal. In experiments 2 and 3, chickens, 23 and 28 days old, respectively, were tube-fed at 1.5 or 1.9 times maintenance level with isoenergetic (metabolizable energy 13.1 kJ/g DM) semisynthetic diets of different protein quality.
