Introduction
The growth hormone (GH) gene plays an important role in growth regulation and development of sheep. Vembur, a hairy mutton type sheep, is one among the eight recognized breeds of sheep in Tamil Nadu, India and is characterized by medium to large size and white colour with irregular tan to red or black patches all over the body. The genomic region consisting of part of exon 2, entire intron 2 and a part of exon 3 (422 bp) of the growth hormone (GH) gene was analyzed for polymorphism in Vembur sheep. The aim was to detect the polymorphism at A781G locus of GH gene in Vembur sheep, as has been reported in Boer bucks (Hua et al., 2009) and Chines goat breeds (LI et al., 2004; Bai et al., 2005; Zhang et al., 2011).
