Extract

Beef producers no longer emphasize excessive fat deposition in market cattle. Recent research findings in human health suggest that our diets should contain less fat because of the cardiovascular diseases that seem associated with greater intakes of fat. Large-frame cattle slaughtered at the same chronological age as small-frame cattle have leaner carcasses and a correspondingly greater proportion of carcass protein (Arnold, Hentges and Trenkle, 1985). Determining early in life whether a type of cattle will become obese, therefore, would be of great benefit to cattle producers. Arnold et al. (1985) reported that, at 6 months of age, large-frame steers were significantly leaner than small-frame steers.
