Calcium and phosphorus in feed and eggshell of layers of different ages



Calcium and phosphorus in feed and eggshell of layers of different ages



Peradarstvo 21(4): 25-28



Egg yield of light hybrid pullets and concentrations of calcium and phosphorus in eggshell were estimated from 24 weeks old, at start of laying, until 74 weeks old. Percentage egg yield at 24, 27, 37, 52, 63 and 74 weeks old was, respectively, 49.2, 82.7, 83.1, 74.5, 61.9, 52.0.
