Mineral RequirementsMineral Requirements• Given as concentration required in
the total diet DM• Includes all the ingredients the
animal is consuming

Mineral RequirementsMineral Requirements• Sheep are more sensitive to Cu
toxicity than are cattle or horses• Do not feed a mineral supplement
formulated for cattle or horses to sheep

Example CalculationExample Calculation• A cow is consuming:• 30 lbs of alfalfa/grass hay (90% DM;
7 ppm Cu)• 4 oz of commercial trace mineral
mix (97% DM; 500 ppm Cu)

Calculate Cu Supply – HayCalculate Cu Supply – Hay• Hay: 30 lbs x 0.90 = 27 lbs DM
27 lbs DM x 0.454 kg/lb = 12.26 kg DM12.26 kg DM x 7 ppm (or 7 mg/kg) =85.8 mg Cu from hay

Calculate Cu Supply – TM mixCalculate Cu Supply – TM mix• Mineral mix: 4 oz x 0.97 = 3.9 oz DM
3.9 oz DM x 28 g/oz = 109.2 g DM109.2 g DM /1,000 = 0.109 kg DM0.109 kg x 500 ppm (or 500 mg/kg) =54.5 mg Cu from mineral mix

Calculate Cu Supply – TotalCalculate Cu Supply – Total• Total Cu in the diet:
85.8 mg + 54.5 mg = 140.3 mg• Total DM intake by cow:
12.26 kg hay + 0.109 kg mineral mix = 12.37 kg• 140.3 mg Cu/12.37 kg DM intake =
11.3 mg/kg Cu (or 11.3 ppm Cu)

Evaluate Cu SupplyEvaluate Cu Supply• If “look at” Cu analysis of hay:
7 ppm vs. 10-15 ppm requirementWrongly conclude DEFICIENT• If “look at” Cu on supplement tag:
500 ppm vs. 100 ppm maximumWrongly conclude TOXIC
