Feed Conversion Ratio (FCR)

first feed mill produces a 28 percent protein fish diet for the same fish that is only KMR 1,800. However, the FCR for this diet is 3.2. This means that to grow the same 1,000 kg of fish will require 3,200 kg of 28 percent feed. The total cost to feed the lower priced fish food would be KMR 5,760,000.
