Ultrasounds are now finding there way to the beef barns. Development and application of real-time ultrasound to improve body composition traits in beef cattle has been looked at for a long time at Iowa State University. With this technology farmers will be able to measure intramuscular percentage fat (marbling) in both live cattle and carcasses. Some programs that are taking place include supporting technician ceritification programs in cooperation with the Beef Improvement Federation, and hosting training programs for potential technicians from around the world. A number of other program are also being looked. Other possible programs include assist breed associations in the development of expected progeny differences (EPD) using ultrasound measures in conjunction with the more conventional carcass traits. One of the biggest benefits to useing ultrasounds is that it will offer the beef cattle industry a tremendous opportunity in terms of selecting superior seed stock animals and in optimal marketing of feedlot cattle.
