摘要：
A swine population of 550 F2 animals was produced by outbred cross using two sires of the native Brazilian breed Piau and 18 commercial dams. The animals were genotyped for 13 microsatellite markers. The evaluated composition traits of carcass were: ham weight, skinless and fatless ham weight, boston shoulder weight, skinless and fatless boston shoulder weight, picnic shoulder weight, skinless and fatless picnic shoulder weight, total loin (bone-in) weight, loin weight, bacon weight, rib weight, jowl weight, sirloin weight, and belly fat weight. Data were analyzed by multiple regression interval mapping, using the QTL Express software. Suggestive QTL were found for skinless and fatless ham weight, picnic shoulder weight, loin weight, and sirloin weight. However, the genomic region should be saturated with additional markers in order to confirm the presence of real QTL.
