| The objective was to map QTL on porcine chromosome 4 and to associate them with carcass and internal organ traits in an F2 population. The F1 population was produced by outbreed crossing, using two native Brazilian breed Piau boars and 18 commercial sows. A total of 617 F2 animals issued from 11 F1 boars and 54 F1 sows were typed for a total of five microsatellite markers. The data were analyzed by multiple regressions developed for the analysis of crosses between outbred lines, using the QTL Express software. Significant evidence for QTL was found for pig chromosome 4 regarding carcass and internal organ traits. All QTL were detected in the same region of the chromosome, designated FAT1. |

| The objective of this study was to evaluate total and individual meat yield of boneless cuts, retail cuts, descarded trimmings and carcass bones of 38 Braford castrated steers, slaughtered at 22 months of age after feedlot finishing. Carcasses were classified in three ranks according to fat coverage: even fat coverage over the carcass, with fat thickness of approximately 6-8 mm on the 12th rib; animals with uneven fat cover, with fat thickness of 3-5 mm and steers with insufficient fat coverage over the carcass, with fat thickness of 1-2 mm. Shrinkage losses decreased as fat coverage increased, and it was 2.57, 2.22, and 1.96%, respectively, for insufficient, uneven, and even fat coverage whereas flank yield increased, reaching values of 13.04, 13.47 and... |
