Relationships between primal cut weights and economic value and live animal, carcass, and meat quality measurements in crossbred pigs
type: CreativeWork
description: The objective of this research was to evaluate relationships between growth performance, ultrasonic, carcass, and meat quality measurements and individual and total primal cut weights, and estimated carcass and primal value of crossbred pigs. The study used a population of crossbred barrows and gilts (n = 6,720) owned by The Maschhoff’s, LLC (Carlyle, IL). The pigs were the progeny of 28 Duroc sires and 1038 Landrace × Large White crossbred sows. The growth performance evaluation was carried out from weaning (18.6 ± 1.09 d of age; 5.4 ± 0.32 kg live weight) to slaughter (196.6 ± 8.0 d of age; 137.2 ± 14.0 kg live weight). Pigs were reared in standard wean-to-finish facilities in single-sire, single-sex pens of 20 at a floor space of 0.68 m2/pig. Pigs had ad libitum access to feed and water throughout the study. Individual pig and pen weights were collected at weaning, week 10 of the study, and at the end of the trial. Pen means for average daily gain (ADG), average daily feed intake (ADFI), and gain: feed (G:F) were calculated for each interim and overall growth period. Ultrasonic backfat depth and Longissimus muscle depth and area were measured at the 10th rib on all pigs prior to slaughter. Carcass weight, dressing percentage, and Fat-O-Meater backfat depth and loin muscle depth at the 10th rib was collected on each carcass on the slaughter line. Carcass fat-free lean percentage was calculated from carcass weight, backfat depth, and loin depth for each carcass. The weight of the Boston butt, picnic, loin, spareribs, belly, ham, carcass length, and meat quality measurements were collected on a sample of 4 pigs from each pen that were representative of the range of live weights in each pen at slaughter. Carcass and primal value of each carcass were estimated using average prices reported by USDA AMS (2020) from 2017 to 2019. Correlations were weak between overall ADG, ADFI, and G:F and carcass value (r = -0.12, -0.22, and 0.15 respectively) and primal cut value (r =…
