[QUOTE="Bright Raven, post: 1584568, member: 27490"] Based on conversation (6/11/2019) with Kelli Retallick, Genetic Services Director, AAA. The baseline data for the foot EPD is from data submitted by members on foot and claw evaluations since 2014. So 5 years of data. It has been supplemented with data that the Association staff have collected from large herds that have good genomic data. An animal has to be at least a yearling before foot scoring. As I stated previously, the numeric scoring data is converted to an EPD metric. The reason there is no scale information from 1 to 4 on a visual scoring basis is because there is no data that had been reported where animals were scored in that range. Her thought is and she said this was not unexpected, most foot problems in the Angus breed fall in the 5 to 9 range - no heel and long claws. In conclusion, the only option now to improve feet qualities is to breed to a bull with a foot EPD of less than 0.5. [/QUOTE]
