Essentially, the all-milk price is being converted from dollars per cwt to dollars per pound of milk produced, and then the cost of producing that milk is subtracted. For example: $19.59/cwt (Pmilk) x 80 lbs/cow/day (DAMP)/100 - $5.90 feed cost/cow/day (DFC) = $9.77 IOFC/cow/day

Phantosmia (phantom smell), also called an olfactory hallucination, is smelling an odor that is not actually there. It can occur in one nostril or both. Unpleasant phantosmia, cacosmia, is more common and is often described as smelling burned, foul, spoiled, or rotten.
