An experiment was carried out to verify the effect of levels of phosphorus and the particle size of dicalcium phosphate on diets for brown egg layer hens during production phase. A complete randomized experimental design as a 2 × 3 factorial arrangement, with two sizes of particles of phosphate (fine and granulate) and three levels of available phosphorus (0.28, 0.38 and 0.48%), totalizing six treatements with five replications of eight birds each, was used. The experimental diets were isoproteic, isocaloric, […]
