| Abstract: | The live cattle eye muscle area, back-fat thickness, height of eye muscle and muscle fat content were determined by ultrasonic. The prediction model for meat production performance was established, the reliability and accuracy of numerical value was high, which reached extremely significant differences through variance analysis. The study provides scientific basis for breeding and evaluation of beef cat-tle. |
