Effects of energy and protein levels on egg quality and performance of laying hens at early second production cycle
(Poultry Science Assoc Inc, 2006-03-01)
One hundred sixty-two commercial 70-wk-old ISA Brown laying hens, previously subjected to induced molting by feed restriction, were distributed in a completely randomized design with 3 x 3 factorial arrangement (i.e., 3 ...

Calcium and available phosphorus levels for laying hens in second production cycle
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2009-03-01)
This experiment studied the effect of four calcium (3.0, 3.5, 4.0, and 4.5%) and four available phosphorus levels (0.25, 0.30, 0.35, and 0.40%) in the diet of semi-heavy commercial layers after molting. Hisex Brown® layers ...
