The growth hormone gene could be an attractive candidate gene for milk production in goats. Single-strand conformation polymorphism was used to identify polymorphism at the goat growth hormone (gGH) gene. For this purpose, genotyping of 90 Talli goat breeds was performed. Nine conformational patterns were observed in exon 4 of the gGH gene, with frequencies of 27.7% for the homozygous pattern (AA) and 72.2% for all of other heterozygous patterns (A/B, A/C, A/B/C, A/B/D/E, A/B/C/F, A/C/F, A/B/E, A/B/F). The results showed that exon 4 of the GH gene in Talli goats is highly polymorphic.
