How to use scrotal circumference
Scrotal circumference (SC) is an important indicator of a bull’s sperm production. Actual SC measurements are a valuable part of prebreeding examinations, and adjusted 365-day SC is used in the Angus genetic evaluation to calculate the SC expected progeny difference (EPD). Actual SC should be used to predict the likelihood a bull will be a successful breeder. However, SC EPD is the best estimate of the bull’s genetic potential.
