ABSTRACT – An experiment was carried out to verify the influence of different levels of energy, vitamin D3 and sodium: chloride ratio on the performance, eggshell quality and on determined blood constituents of 192 laying hens Hy-Line W36, aged 72 weeks, allotted to a 48 experimental units with four hens each. A completely randomized experimental design was used in a factorial arrangement (3 x 2 x 2), metabolizable energy levels (2900, 3000 and 3100 kcal/kg), vitamin D3 levels (500 and […]
