It is well-known that bulls with above average scrotal circumference will produce female offspring that reach puberty sooner and have the potential for greater lifetime reproductive performance.
Beefbreeder members recording with Signet can now include scrotal circumference measurements within their recording program and once a sufficient number of records have been submitted, EBVs will be produced for this trait.
Breeders wishing to submit scrotal circumference measurements should wait until bulls are 400 days of age and then record a scrotal circumference measurement on their weighsheets. Measurements should be in centimetres and taken across the widest point of the scrotum (see diagram).
Collection of this data is entirely at the discretion of individual breeders. If measurements are being collected breeders are advised to use a crush and take care to avoid the potential risk of injury.
