Real-Time Ultrasound: Possible Uses in Genetic Prediction
Ultrasound found its first applications in livestock research in the 1950s.
By William Herring, Department of Animal Science, University of Missouri Extension.
Since that time, the great strides that have been made in ultrasound research have benefited both human medicine and the livestock industry. Most people probably associate ultrasound with human fetal examination. In human medicine, it is most commonly used in routine pregnancy exams and sex determination. This same technology, including identical equipment, is used in the beef cattle industry to evaluate reproductive and carcass characteristics (Figures 1 and 2). However, this publication concentrates on the use of ultrasound to predict carcass merit, specifically genetic prediction for seedstock producers.
