**no units

Question 15

feed efficiency is also called

Answer 15

feed-to-gain

Question 16

what is a good feed efficiency

Answer 16

smaller the number= better/more efficient

Question 17

variable cost

Answer 17

cost of goods/services associated with 1 production cycle (just one group of pigs)

examples:
-fuel
-wages
-rent
-feed**
-market animals
-vet care

sunk cost

Answer 19

money spent that cannot be recovered

as production cycle progresses, more cost become sunk

no longer affect the decision making in short run, withing the production cycle
