Persistence of gastrointestinal nematode (GIN) infection and the related control methods have major
impacts on the sheep industry worldwide. Based on the information generated with the Illumina OvineSNP50
BeadChip (50
K chip), this study aims at confirming quantitative trait loci (QTL) that were previously identified by
microsatellite
‑
based genome scans and identifying new QTL and allelic variants that are associated with indicator
traits of parasite resistance in adult sheep. We used a commercial half
‑
sib population of 518 Spanish Churra ewes with
available data for fecal egg counts (FEC) and serum levels of immunoglobulin A (IgA) to perform different genome
scan QTL mapping analyses based on classical linkage analysis (LA), a combined linkage disequilibrium and linkage
analysis (LDLA) and a genome
‑
wide association study (GWAS)
