Two experiments were conducted to evaluate different sources of supplemental phospho-
rus for growing-finishing beef sterrs. In the first experiment 30 Hereford weanling steer cal-
ves were placed on a phosphorus-deficient ration for 69 days, then alloted to treatment to test the availability of phosphorus from a chemical mixture of 87% mono- and 13% dical-
cium phosphate, defluorinated phosphate, Mexican rock phosphate, sodium tripoly phos-
phate 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, Mexi-
can 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 signifi-
cant differences were detected among phosphorus supplements for any of the parameters
measured. For most parameters measured in both experiments, the chemical mixture of 87% mono- and 13% dicalcium phosphate appeared to be the least satisfactory phospho-
rus supplement. |
