Body size was estimated by multiplying the average of the hip and chest widths by body length and chest depth in 208 ewes of three genotypes: Targhee x Targhee (TXT), Finn x Targhee (FXT), and Suffolk x Targhee (SXT), and two seasons, fall (pre-breeding) and spring (post-lambing). The estimated ewe body size did not fluctuate with season, body condition or physiological stress and proved to be a constant measure of size. Measuring linear body dimension is time consuming; and hence ewe body size can best be approximated by the chest depth in a regression equation. In the absence of linear …

Thirty-five range cows of various breeds were obtained for the study. Body measurements taken were live weight and hip height and all cows were condition scored for level of fatness. The cows were slaughtered and the following morning several carcass measurements were taken and the plate was removed from the left side. These plates were boned and the remaining flesh ground for chemical analysis of percent carcass fat. Regression equations were calculated for estimating percent carcass fat from condition score, weight:height ratio and hip height (R2=.765). However, condition score alone is the single best estimator for percent carcass …
