Dairy Well: hygiene scoring
Which animals to assess:
- Lactating cows
- Dry cows
- Heifers
- All calves on milk
- Sample across all represented ages
- Hospital pen (lactating and young stock)
The number of animals scored per group will be determined with the sample size calculator.
When to assess:
- Assess lactating cows while walking to the milking parlor or before or after milking
- In home pen
How to assess:
Assess the areas of the body that contact the lying area divided into two areas: belly (including udder on mature animals) and thigh, both outlined in gray below. The tail head, top-line, and lower legs are not evaluated. If both sides of the animal are visible, score the worst side.
Goal:
To assess the cleanliness and dryness of the resting area.
≤25% of each group should score a 3.
Score 1
- Manure or mud (may be dried) in either of the 2 focal areas is less than 10" (adults, heifers) or 5" (calves) in diameter
Score 2
- An area of manure or mud (may be dried) > 10" (adults, heifers) or 5" (calves) in diameter in 1 of the 2 focal areas
Score 3
- Area of manure or mud (may be dried) > 10" (adults, heifers) or 5" (calves) in diameter in 2 of the 2 focal areas
National Dairy FARM Program: hygiene scoring
Which animals to assess:
Score all age classes of animals in all pens; the number to score in each class is determined by the sample size calculator using the total number of animals on the farm.
Goal:
To assess the cleanliness of the udder.
<10% of the herd should score a 3 or 4.
