Description	Allometry of total nitrogen and amino acid growth and apparent efficiency of amino acid and nitrogen retention were examined in slow-growing laying type cockerels (SG) and in fast-growing male broiler hybrids (FG) during the growing period from hatch to Day 22. Allometric coefficients for nitrogen in relation to body weight were 1.080 and 1.099 for SG and FG chickens, respectively. Allometric coefficients relating amino acids to body nitrogen were less than unity in most cases which indicated that an increasing amount of non-protein N might be deposited in the body with advancing age. Except for cysteine, the apparent efficiency of amino acid retention was lower in SG as compared to FG chickens. The high retention efficiency of cysteine in SG genotype was likely associated with the conversion of surplus methionine to cysteine, required for feather protein synthesis in laying-type birds in an early age.
