Abstract

A study was conducted to evaluate the effects of dicalcium phosphate, Tapira phosphate and monocalcium phophate for sows during gestation and lactation. The data were collected during four parities. The study involved sixty crossbred Landrace x Large White gilts with 135.6kg average weight and 8.3 months old. The experiment was a completely randomized block design with three treatments and ten replications. The experimental unity was represented by two gilts in both gestation and lactation periods. The statistical model included the effects oftreatments, blocks, cycles, animals and the treatment x cycles interaction. The basal diets were formulated to contain either 12%crude protein in gestation and 13% in lactation. Except for weight gains during gestation, productive performance traits were iqually (P> 0.05) effected by the different phosphorus sources. The Tapira phosphate and monocalcium phosphate appear adequate for sows in gestation and lactation, for all criteria measured, when compared with dicalcium phosphate.
