Ultrasound Scanning

Successful purebred breeders give their customers what they want. Ultrasound is a tool that allows you to tell your customers how your genetics will impact the performance of their cattle now and into the future. Ultrasound animals provide you with fast, economical, and proven data on carcass composition of breeding stock at your fingertips.

Ultrasound of bulls and heifers can determine their genetic merit for carcass traits actually looking under the hide, without harvest. These traits are heritable. Genetic evaluation of these traits will allow breeders to select animals with the carcass traits that they desire for their breeding program.

Before the use of ultrasound in beef cattle, formal progeny testing was the only method to collect carcass data on seedstock. Test bulls, as well as reference sires, are bred to cows with the resulting progeny finished to slaughter and carcass measurements taken. This method is time consuming, expensive and impractical for many producers. EPDs are more useful than actual data in providing the best genetic prediction of the carcass merit of the animal. Ultrasound data, like other measured performance data, can vary year to year due to changes in feed (drought/nutrition), age at scanning, etc.

Canadian Angus members who collect performance information are encouraged to ultrasound breeding stock, especially replacement females which form the baseline of your herd. Ultrasound data from young bulls and heifers between 320 and 440 (for bulls) and 460 (for heifers) days of age are used in national genetic evaluations, producing North American Angus EPDs for marbling, fat and ribeye area. Lean meat yield is also calculated on scanned cattle. All data must be collected by a CUP certified technician.

Quick Facts

  • Herds must be enrolled on the Canadian Angus Performance Program.
  • Cattle are listed by tattoo, scan date, scan weight and management group on the barn worksheet.
  • Ultrasound images, chute form and barn worksheet need to be sent to the lab.
  • Cattle require a 205 day weight on file at CAA before the ultrasound scan is done.
  • Only scan bulls between 320–440 days of age and heifers between 320–460 days of age.
  • Weigh cattle the day of the scan prior to any feeding. It is preferable that they be held off feed overnight. The scan weight is used to predict empty body weight.
  • Cattle must be clipped to within 1/2 inch in all areas of scanning to improve image quality.
