Abstract
Basal ration containing 5 or 10% of fish meal was supplemented with 0.5% of L-lysine HCl, but there were no improvements on the chick growth, feed efficiency and protein efficiency ratio.
When supplemented with 0.2% of L-lysine HCl, there were remarkable increases on the growth, feed efficiency, protein efficiency ratio and protein accumulation.
On these all cases, there were no remarkable effects on the body composition of experimental chicks.
