379. Multivariate GWAS revealed a critical region on chromosome 4 for developmental and feather growth traits in ducks

Abstract

Aim of this study was to discover the genetic variants for average daily gain (ADG), body weight (BW) and primary feather length (PRF) traits in Pekin ducks. Using 1215 ducks and 45 k autosomal SNPs, multivariate and univariate genome-wide association analyses were performed. A total number of 50 markers were identified as common between all analyses and these SNPs were co-localized on chromosome 4. Current findings confirm previously reported findings for growth in ducks while proposing novel genetic loci associated with feather development and growth in ducks.
