EXAM 1: Production Calculations Flashcards
conception rate equation
(# of sows pregnant / # of sows bred) * 100
average herd conception rate
75-90%
farrowing rate equation
(# of sows farrowed / # of sows bred) * 100
average herd farrowing rate
85%
culling percentage equation
(# of sows culled / total # of sows ) * 100
commercial farms in the U.S annual culling rate often exceed _________ with the average rating from ____to______
50%
35.7-49.5%
reasons to cull
feet and leg issues
too old
too big
repro failure
mortality rate equation
(# of dead pigs / # of starting pigs) * 100
national average of farrow-to-wean mortality
12.9%
the mortality rate is influenced by
environmental conditions
disease
lameness
weaning weight
health status
ADG equation
total pounds gained / days on feed
ADG definition
measure of live weight gain per day
what influences ADG
health status
environment
age at weaning
weaning weight
feed efficiency equation
pounds of feed/ pounds of gain
**no units
feed efficiency is also called
feed-to-gain
what is a good feed efficiency
smaller the number= better/more efficient
variable cost
cost of goods/services associated with 1 production cycle (just one group of pigs)
examples:
-fuel
-wages
-rent
-feed**
-market animals
-vet care
fixed cost (operating cost)
cost of goods that last more than one production cycle
examples:
- machinery
-breeding livestock
-building
-land
-depreciation cost
-intrest
-insurance
-taxes
-repairs
sunk cost
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
breakeven price equation
(variable cost + fixed cost)/ market weight of pig
breakeven price
total amount of money an animal must be sold for to cover all the costs associated with raising the animal
average $2-5
