The objective of this research was to study productive and economical aspects of laying hens (Gallus gallus) submitted to different housing densities. Two hundred and sixty-four laying hens were housed in cages with dimensions of 100 cm × 50 cm × 40 cm in a randomized complete design with four groups distributed in a 4 × 4 factorial arrangement, with 8, 10, 12 and 14 animals/cage, corresponding to 625, 500, 416,6 and 357,14 cm2/animal. The following characteristics were assessed: egg […]
