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

14

total profit

avg carcass wt * profit margin = X
X * total birds sold = total profit
