Abstract: Suppression subtractive hybridization (SSH) is a kind of technology which is now widely used to find differences in gene expression.  It is accepted by most researchers because of its characteristics of high efficiency, stability and reliability. The advantage of SSH is that it can be used in different environment, different physiological condition of tissues or cells to research the expression of genes. In recent years, with the development of molecular biology, screening and cloning differentially expressed genes has gradually become the research focus. This review summarizes the current research about SSH using in production performance, diseaseresistant mechanism and variety differences of goose, duck and chicken, thus providing more reference for using SSH to research the life activities of the molecular mechanism.

Key words: suppression subtractive hybridization (SSH), differential expression genes, poultry
