Incorporating ultrasound on commercial or seed stock operations will save generations of time to develop and maintain improvement in carcass quality, improving overall cow efficiency or simple design of an end product for the consumer. Ultrasound scanning can determine ribeye size, marbling, back fat, and modern software, determine ribeye score which corresponds to retail product. As a trained technician I can determine the degree of tenderness and stress with extremely high accuracy. Individual feed conversion can be determined in any group feeding situation. Cornell Value Discovery System (CVDS) is a mathematical model requiring inputs. In the case of the CVDS, the inputs are gain on test, carcass measures, ration ingredient analysis, and environmental factors.
