• For individual calf hutches, evaluate 30 of
  hutches.

Determining observation numbers
Example 1,000 cow dairy estimated herd profile
Far-Off Dry 15 (150 cows) Fresh 4 (40 cows)
Close-up Dry 5 (50 cows) High 33 (330 cows)
Hospital 1 (10 cows) Mid Late 42 (420 cows)

• FODC 1 pen
• CUDC 2 pens
• Hospital 1 pen
• Fresh 1 pen
• High 3 pens
• Late 5 pens

Pen numbers

Example calculations 1,000 cows

• Population 1,000
• Prevalence assume worst case of 50
• Observation number (from table) 88 animals
• Spread 88 observations over groups designated by
  proportion
• Account for numbers in observation groups only
• (subtract far off dry cows hospital numbers
  16)

Locomotion Footing
High All of 1 pen
Late All of 1 pen
BCS, Hygiene, Tails, Hock/Knee Swelling
CUDC 5 animals from 2 pens (88 .06)
Fresh 4 animals (88 .05)
High 35 animals from 2 pens (88 .40)
Late 44 animals across 3 pens (88 .50)
