Název v původním jazyce

Allometric growth of major bone-forming minerals in slow- and fast-growing chickens during the first weeks of life.

Popis výsledku v původním jazyce

Allometric growth of body macrominerals 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 dry matter, calcium, phosphorus andmagnesium in relation to body weight were 1.091, 1.427, 1.383 and 1.284 for SG chickens and 1.075, 1.276, 1.233 and 1.216 for FG chickens, respectively. The deposition of Ca, P and Mg in SG chickens were faster than that of dry matter by 30.20 %, 25.97% and 17.24 %, and in FG cockerels by 18.45 %, 14.27 % and 12.71%, 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) in SG chickens thus suggesting that the relative growth of these minerals may be affected by genotype.
