Abstract
A method and system for determining meat quality in cattle is provided. In preferred embodiments the method comprises obtaining an ultrasound measurement of a cattle specimen between the 12th rib and 13th rib at weaning age. The ultrasound measurement is utilized to extrapolate a harvest quality parameter. Based on the harvest quality parameter, and preferably a yield grade, the specimen is categorized. Particularly preferred harvest quality parameters are ribeye area, fat thickness, intramuscular fat and ribeye shape. Methods for determining tenderness, stress and intramuscular fat are described and claimed.
Claims2
A process for predicting meat tenderness in an animal comprising the steps of:
- obtaining a longitudinal ultrasound measurement of a longissimus dorsi muscle of said animal;
- determining an angle of connective tissue in said longissimus dorsi muscle relative to a centerline of said animal;
- and
- assigning a tenderness grade based on said angle of connective tissue wherein said tenderness grade comprises:
- a first grade wherein said angle is less than approximately 27°;
- a second grade wherein said angle is at least approximately 27° to approximately 40°;
- and
- a third grade wherein said angle is greater than approximately 40°.
A process for predicting meat tenderness in an animal comprising the steps of:
- obtaining a longitudinal ultrasound measurement of a longissimus dorsi muscle of said animal;
- determining an angle of connective tissue in said longissimus dorsi muscle relative to a centerline of said animal;
- and
- assigning a tenderness grade based on said angle of connective tissue wherein said angle is determined at a location of approximately ¾ the length of a longissimus doris muscle between the 12th rib and 1st lumbar.
