Abstract

Two experiments were conducted to evaluate different sources of supplemental phosphorus for growing-finishing beef steers. In the first experiment 30 Hereford weanling steer calves were placed on a phosphorus-deficient ration for 69 days, then allotted to treatment to test the availability of phosphorus from a chemical mixture of 87% mono- and 13% dicalcium phosphate, defluorinated phosphate, Mexican rock phosphate, sodium tripoly phosphate and a 1:1 mixture of defluorinated phosphate and sodium tripoly phosphate. In the second experiment 48 Hereford weanling steer calves were used to test the availability of phosphorus from a chemical mixture of 87% mono- and 13% dicalcium phosphate, Mexican rock phosphate, monosodium phosphate and two sources of defluorinated phosphate. In both experiments average daily gain, feed intake, final weight and serum inorganic phosphorus were significantly greater and serum calcium significantly lower for animals supplemented with all sources of phosphate than animals not supplemented. No significant differences were detected among phosphorus supplements for any of the parameters measuredi For most parameters measured in both experiments, the chemical mixture of 87% mono- and 13% dicalcium phosphate appeared to be the least satisfactory phosphorus supplement.
