Summary of nuclear markers significantly associated/linked<sup>1</sup> to growth traits and their annotations.

1<p>Body weight was recorded on each animal at approximately 7 (Weight2), 9 (Weight3) and 12 (Weight4) months post-hatching. A family-based sample that included 40 full-sib families each with 17 progeny were genotyped with 30 SNPs.
