Genome-wide association studies for sheep growth and meat production traits using Illumina OvineSNP50 BeadChip

ABSTRACT: Mear prodution is the most important trait for sheep. In this study, we performed a Genome-wide association study (GWAS) by using Illumina Ovine SNP50 BeadChip in 329 purebred sheep phenotyped for 11 growth and meat production traits (birth weight, weaning weight, 6-month weight, eye muscle area, fat thickness, pre-weaning gain, post-weaning gain, daily weight gain, height at withers , chest girth and shin circumference). A total of 319 sheep and 48,198 SNPs were fitted using TASSEL 3.0 software as random effects in a mixed linear model. 36 chromosome-wise significant SNPs were identified for 7 traits and 10 of them reached genome-wide significance level consistently for post-weaning gain. Gene annotation was implemented based on the latest version3.1 ovine genome sequence (released Octobe
