Calcium, magnesium and phosphorus retention in chickens with different growth rate fattened to higher age.
Original language description
Utilisation of Ca, Mg and P was examined in broilers and laying type cockerels from Day 23 to Day 100. In meat type chickens coefficients of apparent Ca and P retention decreased highly significantly during the whole experiment while that of Mg decreasedtill the age of 93 days. In egg type chickens the dependence of Ca retention on age was expressed by the parabola of the 2nd degree with a minimum on Day 70. Utilisation of Mg and P decreased linearly and highly significantly. Content of Ca and Mg in body gains of broilers increased (P<0.01) with age. Concentration of P culminated on Day 45. In laying type chickens the level of Mg increased and that of P decreased (P<0.01). The Ca content in body gains decreased till Day 43; thereafter, an increase wasrecorded. Differences in average coefficients of Ca and P retention and retention per unit of body gain in slow growing hybrid and broiler chickens were not significant while retention of Mg was highly significantly higher in laying type
