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
There shouldn't be any weird smells in your nose at any time after a Rhinoplasty. Odd smells, redness and increasing pressure are all signs of possible infections after a Rhinoplasty and you should be seen by your Rhinoplasty surgeon ASAP for a nasal exam.
Cats have very sensitive noses, and even a slightly unpleasant smell can cause them to recoil in distaste. Also, remember that cats do not like the same smells that people do, so while you might really love that expensive perfume that you bought at the local boutique, your cat's sensitive nose might not be able to handle your intense scent.
