How the Feed Conversion Ratio Calculator works
Feed conversion ratio = total feed given ÷ total weight gained, so a lower number means the animals turn feed into weight more efficiently. Feed cost per pound of gain = ratio × feed price per pound, where the price per pound is the price per ton ÷ 2,000. Use the same basis for feed and gain, such as as-fed or dry matter, when you compare groups. Good ratios depend on the species, the age, and the ration, so compare your own groups over time. Example: with Total feed given 4200 lb, Total weight gained 1500 lb, Feed price 320 $ per ton, Days on feed 120, and Number of animals 10, the result is Feed conversion ratio (lb feed per lb gain) = 2.8; Feed cost per pound of gain = $0.45; Average daily gain per animal (lb) = 1.25.
