Interpretive Summary:

Technical Abstract: The objective of this review is to summarize relevant results from the use of genomics in sheep. Genomics has been used to identify genes associated with production, reproduction, carcass traits, and disease-related traits in sheep. A brief discussion on the concept of genomics is included. Genome-wide Association Studies (GWAS) have been used to identify chromosomal regions associated with growth. Several ovine chromosomes harbor genes associated with economically important traits in sheep. Genomics has been used to identify genes influencing growth, prolificacy in ewes, carcass traits, and disease resistance. The use of genomics in the sheep industry has the potential to increase profitability of the sheep industry by either, improving the production or minimizing losses.
