With these Wagyu sires, you can breed a herd that produces excellent beef.
With our sires at Prime Valley Farms, you can breed a 100% fullblood herd.

SCD, or Stearoyl CoA Desaturase, is a gene family that distinguishes the healthy fat marbling in Wagyu beef from other beef. SCD testing identifies cattle with the dominant Japanese genotype that produces a certain fat composition.
- Stearic acid and the amino acid valine (V) make deposited fat harder.
- Oleic acid and the amino acid alanine (A) make deposited fat softer (and more flavorful).
- The genotypes for SCD testing are VV, VA, and AA — AA is the most desirable.
Tenderness describes the amount of force it takes someone to cut or chew a piece of meat. Wagyu beef has been documented to be significantly more tender than the beef resulting from any other breed of cattle.
The IGENITY Tenderness test is a genetic profile analysis which evaluates a given animal's DNA and attempts to rank the expected resulting meat tenderness. The IGENITY Tenderness values are assigned from 1 to 10.
It should be noted that no Wagyu cattle have been used to validate the claims of this genetic test, and one should therefore use the test cautiously when comparing Wagyu animals.
Wagyu can be affected by, a carrier for, or free from a recessive trait (or genetic condition).
Spherocytosis (B3) is one of four recessive genetic conditions that the Australian Wagyu Association recognizes. B3 is a disorder of the red blood cells’ surface membrane that causes anemia and severe retardation in Wagyu growth.
Chediak Higashi Syndrome (CHS) is the second recessive genetic condition. CHS is a macrophage (white blood cell) disorder that compromises Wagyus’ immune systems and makes their blood slow to coagulate, giving them an unusually pale color.
Claudin 16 Deficiency (CL16) is the third recessive genetic condition. CL16 is a gene disorder on Chromosome 1 that causes terminal kidney failure. The onset can occur anytime in Wagyu starting in late adolescence, and cattle with CL16 are unlikely to live more than six years.
Factor XI Deficiency (F11) is the fourth recessive genetic condition. F11 is an autosomal disorder associated with prolonged bleeding time and abnormal coagulation. However, this is a non-fatal condition, and affected Wagyu can live and breed normally.
