Beef:
(cow-calf pairs) = 0.8*(205/365)*(beef cow)
(maintenance) = (1 - 0.8)*(205/365)*(beef cow) + (160/365)*(beef cow) + (bulls) + (beef NOF heifer) + (beef NOF steer)
(finishing) = (beef OF heifer) + (beef OF steer) 

Poultry:
(broilers) = (broilers)
(male turkey) = 0.5*(turkeys)
(female turkey) = 0.5*(turkeys)
(layers) = (hens) + (chickens) + (pullets)

Dairy:
(lactating) = (dairy milk cow)
(dry) = (dairy dry cow)
(heifer) = (dairy heifer)

Swine: 
(finishing) = (2/3)*(swine60 + swine60_119 + swine120_179 + swine180)
(weaning) = (1/3)*(swine60 + swine60_119 + swine120_179 + swine180)
(lactating) = (1/6)*(swine breeding)
(gestating) = (5/6)*(swine breeding)
