| Resumo: |
The experiment was carried out in the aviary of Iguatemi Experimental Farm, at Universidade Estadual de Maringá, Maringá, state of Paraná, Brazil, from August 17 to December 6, 1996. After forced molting, 180 commercial laying hens were distributed in a completely randomized design with 5 treatments, 6 replications, and 6 hens for experimental unit. Five isoproteinic (18.68% CP), isoenergetic (2,900.00 kcal ME/kg), isophosphoric (0.46% aP) diets with 3.50%, 3.80%, 4.10%, 4.40% and 4.70% calcium were served. No effects (P > 0.05) of calcium levels were found in the egg laying rate, ration consumption, food conversion and eggshell percentage. A linear increase (P < 0.05) in specific weight was found with the increase of calcium levels. A quadratic effect (P < 0.05) was found in calcium levels on egg weight. It may be concluded that up to 4.7% calcium may be used efficiently for post-molt commercial laying hens.
