Birth Data

Birth Data includes birth date and birth weight, calving ease scores and udder scores. It is important to get all of the data on the entire calf crop but if a data point is not available, such as birth weight, please do not guess what the weight was. A missing datapoint is much better than an inaccurate data-point.

Birth weight records should be collected on calves within 24 hours after birth. Hoof tapes are an acceptable method to measure birth weight, but please indicate when a tape is used and use the same method for the entire calving season.

Calving Ease Score indicates how easily a calf was born. If a calf’s birth was unobserved (hence unassisted), use a 1 as the primary score.

1 = Born unassisted
2 = Easy pull
3 = Hard pull
4 = Cesarean
5 = Abnormal presentation

Udder and Teat Scores should be collected within 24 hours of calving. Two scores are assigned based on udder suspension (1–9; with 9 being very tight and 1 being very pendulous) and teat size (1–9 with 9 being very small and 1 being large and misshapen). Ideally one person scores all the udders/teats during the calving season for consistency.
