DATA COLLECTION BY TRAIT
When to measure:
Within 24 hours of birth.
How to measure:
Must be measured with a scale in pounds. Cannot be measured with a tape or estimated.
When to score:
At birth.
How to score:
Use the 1-5 scoring system:
- No Assistance
- Some Assistance
- Mechanical Assistance
- Cesarian Delivery
- Abnormal Delivery
Score all females:
Only scores on heifers are used in the genetic evaluation, but it is helpful to track the data on all calves born in the herd for management purposes.
When to score:
Twenty four hours before or after calf birth, which is when the udder would be fullest.
How to score:
Evaluate both the teat size and udder suspension on a scale of 1 to 9 on the combined worst quarter for both traits.
Females should be given a separate score for both traits.
Teat:
Consider both length and diameter.
Udder:
Evaluate on suspension – ranging from very pendulous to very tight.
Calculating gestation time?
Use our gestation calculator tool to determine gestation time on females.
REPORT FOSTERED CALVES
Report the foster dam tag on the birth record of the calf.
When calves are fostered after birth to a dam that did not give birth to them (e.g. birth dam dies, birth dam has little milk, calf was a twin, etc.), the foster event needs to be recorded.
COLLECT DNA
DNA samples for parent verification and other uses can be collected at birth.
