The small intestine is a vital organ in animal gastrointestinal system, in which a large variety of nutrients are absorbed. To identify quantitative trait loci (QTL) for the length of porcine small intestine, phenotypic values were measured in 1034 individuals at 240 d from a White Duroc x Chinese Erhualian intercross F(2) population. The length of small intestine showed strong correlation with growth traits and carcass length in the F2 population. A whole-genome scan was performed based on 183 microsatellites covering the pig genome in the F(2) population. A total of 10 QTL for this trait were identified on 8 pig chromosomes (SSC), including four 1% genome-wide significant QTL on SSC2, 4, 7 and 8, one 5% genome-wide significant QTL on SSC12, and five 5% chromosome-wide significant QTL on SSC5, 7, 13 and 14. The Erhualian alleles were generally associated with shorter length of the small intestine except the alleles on SSC7 and 13. The QTL on SSC4 overlapped with the previously reported QTL for the length of small intestine. Several significant QTL on SSC2, 8, and 12 were consistent with previous reports. The significant QTL detected on SSC7 was reported for the first time. All QTL identified in this study corresponded to the known region significantly associated with growth traits, supporting the important role of the length of small intestine in pig growth.
