ABSTRACTPaired loins from 18 barrow and gilt carcasses were randomly selected to evaluate the effect of marketing on the nutrient composition of fresh pork loins. The paired loin from one side was shipped through a predetermined marketing system, while the control loin was transported immediately back to Beltsville, MD. Rib chops from each loin were analyzed for key nutrients. The overall results from this study indicate that pork loins subjected to extreme marketing conditions have weights, appearance and quality traits and nutritional composition similar to loins shipped from a slaughter plant directly to the research facility. Thus, pork samples handled by a controlled research technique and sampled at the point of slaughter are basically equivalent to what the consumer purchases at the retail level.
