This work aimed to evaluate the effect of two different rearing systems (cages and litter) on productive performance and egg quality of laying hens. The trial was conducted for five experimental periods of 28 days each. Sixty four pullets of the laying strain Isabrown and 64 pullets of the laying strain Hy-Line W-36, with ages of 19 and 21 weeks, respectively, were used. The combination of two rearing systems (conventional cages and floor system with litter) and two layer strains […]
