Accretion Rates and Efficiency of Amino Acid Utilization during the Twenty-nine Days Post-Hatch Period in Male Ducks

The Journal of Poultry Science, 2012
The amino acid contents of whole body were determined in male ducks at 5 age intervals from d 1 to 29 post hatch. Whole body homogenates were analyzed of dry matter, nitrogen, and amino acids and used to determine amino acid accretion rates and ...
