Abstract

Two performance trials were conducted in order to evaluate the effect of phosphate sources in the swine performance. In the first trial one hundred eighty crossbred pigs (Landrace x Large White) with initial average weight of 23,0kg were utilized. The experiment consisted in completely randomized block design with five treatments and six repetitions. The phosphates source tested were, dicalcium phosphate, monocalcium phosphate (50%) + Tapira phosphate (50%), monoamonium phosphate, Fosforindus and calcinated bone meal. In the second trial two hundred fifty two crossbred pigs (Landrace x Large White) with initial average weight of 24,0kg were utilized. The experiment consisted in completely randomized block design with five treatments and six repetitions. The treatments were made by diferent combination levels between Patos de Minas phosphate and monoamonium phosphate. In both trials all diets, based on corn and soybean meal, were isoproteic (15% crude protein for growth and 13% for finishing) and isocaloric (3350 kcal Dig. Energy/kg). From each experimental group two animals were slaughtered and the third metacarpal removed to determine the bone characteristics. Except for Patos Minas phosphate as phosphate source, in witch the performance, bone weight, bone fluorine data were lower (P < 0.05) than those other alternative phosphate sources tested. All performance and bone characteristics data were similar (P > 0.05) for all other treatments tested.
