Development of a multivariate yield grade equation to predict compositional traits in mature cow carcasses
Article Abstract:
A new yield grading equation was developed based on data from 68 cow carcasses. Current Department of Agriculture yield grade equations are based on the most economically important fabrication yield for young beef carcasses, and thus do not effectively reflect the compositional traits across maturity groups of cow carcasses. Three new yield grade equations were proposed for the different trade segments of the cow meat industry. Use of the equations would vary depending on the products of the trade segment. Combined with standard quality grades, the scheme permits uniform trading of cow meat.

Live and carcass values from different cattle types
Article Abstract:
The effect of three fat trim levels and drop credit on the valuation of both live animals and carcasses from various cattle types was investigated. Cattle types with leaner carcasses were found to have higher total values. Choice grade carcasses maintained a constant value difference from Select carcasses, but the proportion of Choice carcasses was generally less in leaner cattle. The value of some cattle types increased when hide and offal were considered. The value advantage of leaner cattle is more pronounced when subprimal cuts are trimmed more closely.

Effect of frame size, muscle score, and external fatness on live and carcass value of beef cattle
Article Abstract:
The effect of frame size, muscle score, and external fatness on live and carcass value of beef cattle was studied using commercial slaughter steers and heifers of varying frame size, muscle thickness and rib fat thickness. Results show that live and carcass value is greatly affected by carcass fatness and muscle score as shown by the fact that the price for cattle decreases with fatter and lighter-muscled cattle.
