In lysine trial for broilers, birds fed lysinedeficient
starter diets had poorer breast meat yield at
market age than those fed lysine-adequate starter diets,
although the lysine-adequate diets were fed to all
birds during the subsequent growing period (Kidd et
al., 1998), implying that deficiency of dietary amino
acid in starter period of birds would retard breast meat
development in the subsequent period. Therefore, the
effect of arginine on breast meat was considered and
the requirement for this meat was discussed.
