Allometric coefficients for dry matter, calcium, phosphorus, magnesium, sodium and potassium in relation to body weight were 1.091, 1.427, 1.383, 1.284, 0.843 and 1.097 for SG chickens and 1.075, 1.276, 1.233, 1.216, 0.943 and 1.144 for FG chickens, respectively. Allometric coefficients describing the relationships of Ca, P, Mg, Na and K with dry matter weight were 1.302, 1.260, 1.172, 0.772 and 0.998 for SG chickens and 1.185, 1.143, 1.127, 0.878 and 1.059 for FG chickens, respectively. High allometric coefficients for Ca, P and Mg in both genotypes likely indicate a rapid growth of skeletal tissues which requires an adequate mineral nutrition during this period of growth. The deposition of Ca and P relative to dry matter was higher (P<0.05) and that of Na lower (P<0.01) in SG chickens thus suggesting that the relative growth of these minerals may be affected by genotype." .
