SCD typing in Wagyu is designed to aid in the selection of cattle with the inheritable genetic coding that produces a superior fat composition. Stearoyl CoA Desaturase (SCD) is the protein that is encoded by the SCD gene and is the enzyme that changes saturated fatty acid (Stearic Acid) that generates a harder fat with a higher melting point into an unsaturated fatty acid (Oleic Acid) that results in a softer fat with a lower melting point. Not only is unsaturated fat healthier; it is more desirable and pleasing to the palate. DNA sequences in Wagyu cattle are placed into two classifications of amino acids: A (Alanine) and V (Valine). Wagyu carry a genetic mutation that changes Valine to Alanine: the presence of A type amino acids have a lower melting point of fat. The preferred SCD designation is AA.

18% of Wagyu are designated as AA, 74% VA, and 8% VV.
