Composição química de diferentes fontes de fósforo e deposição de metais pesados em tecidos de suínos (Chemical composition of different phosphorus sources and heavy metal deposition in tissues of swines)

One hundred twelve pigs averaging weight of 28.68kg, were allotted to a completely randomized blocks with seven replicates of two animals per box. The treatments consisted in factorial 8×2 (eight phosphorus sources x two sexes). The experimental diets were formulated based on corn and soybean meal and the phosphorus was supplemented through phosphate dicalcium (FBC), monodicalcium (MBC), triple superphosphate (ST),
