ABSTRACT
Extensive reviews of the application of ultrasound for evaluation of live beef, sheep, and swine for the previous 30 years have demonstrated the extent of the previous research and the improvements that have been realized. Topics have included the application of ultrasound for feeding and finishing animals,[7] and for the selection of breeding stock[8] and the effect on genetic improvement. Ultrasound has been used for the selection of breeding hogs for more than 20 years. Images were interpreted visually by humans and measured manually with the aid of planimeters or computers. Results have shown that automation of the process for interpreting animal ultrasonic images was feasible.
