Summary and Implications
Twenty-three people participated in two National Swine Improvement Federation ultrasound certification workshops in January 1995. Each participant's ability to predict backfat and loin muscle area on live market hogs was determined. IBP Inc,. Madison, Nebraska cooperated in the collection of carcass data for certification purposes. Nine participants were certified for backfat and loin eye readings and eight participants qualified for certification of backfat only. The workshops provided the pork industry with additional expertise in the use of ultrasonic measurements to determine backfat and loin muscle area on live swine.
