1
hatchability
# hatched / total eggs = X / 100
2
infertility
100 - hatchability
3
feed conversion
# of chicks * live weight = X
lbs. of feed / X = feed conversion
4
average carcass weight
% carcass yield / 100 = X / live weight
5
breast meat weight
average carcass weight * % of breast meat = X
X * # of birds = breast meat (in lbs)
6
daily manure output
# of birds / 100 = X
X * pounds of daily manure produced = daily manure output
7
price per pound
avg lbs each * # of birds = X
auction price / X = price per pound
8
breast meat yield (per carcass)
avg breast meat wt / avg carcass wt = X / 100
9
feed conversion (per dozen eggs)
% production rate / 100 = X / # of birds
X * # of days = y
y / 12 = feed conversion per dozen eggs
10
mortability
starting # of birds - finish # of birds = X
X / starting # of birds = X / 100
11
hen-day production (per day)
total # of eggs/7= X
X / # of hens = %
12
hatchability of settable eggs
total # of eggs - unsettable = X
X - infertile = y
# of chicks hatched / y = z / 100
13
feed consumption
# of broilers * feed conversion = X
X * avg live wt = feed consumption in lbs
