Egg production, eggshell quality and profitability of laying hens during first cycle with levels of calcium and available phosphorus
In order to evaluate the importance of calcium and phosphorus for egg shell quality, a trial was conducted using 480 Hy-Line 36 hens in a 3*4*3 factorial arrangement to evaluate three calcium (Ca) (3.2, 4.2 and 5.2 %) and four available phosphorus (Ap) levels (0.15, 0.20, 0.25 and 0.30 %) during 20 to 72 wk of age).
