Extract

Dicalcium phosphate accounts for 70% of the total costs of mineral mixtures in Brazil and studies have been made of the use of alternative supplementary phosphorus sources for ruminants (SILVA FILHO et al, 1992). The aim of this work was to evaluate monoammonium phosphate (MAP), triple superphosphate (TSP) and Tapira rock phosphate (TRP) as alternative P sources to the expensive dicalcium phosphate (DCP) by studying the kinetics of radiophosphorus (32P) in the blood of sheep given such supplements.
