Wagyu Breeding Bloodlines

WAGYU BREEDING - WHAT BLOODLINE SHOULD I CHOOSE? When it comes to Wagyu bloodlines, there's a lot to learn and a lot to choose from.  We've listed some of the most common bloodlines below and their traits.

Tajiri or Tajima

 

Originating from the Hyogo prefecture, these black cattle were originally used to pull carts and plows so the developed larger forequarters and lighter hindquarters. They are generally smaller framed with slower growth rates, but produce excellent meat quality with large eye muscle and superior marbling. They are thought to be ideal for the production of F1 cattle for slaughter. The Tajima bloodlines are generally regarded as producing the best quality meat in all of Japan.

Fujiyoshi or Shimane

 

From the Okayama prefecture are medium framed cattle with average growth rates and good meat quality.

Tottori or Kedaka

 

From the Tottori prefecture were originally pack animals in the grain industry, so they are larger animals with straight, strong back lines and generally good growth rates. However, their meat quality is variable. Best strain for milking ability. Combinations of all 3 lines are often used for Fullblood meat production.

Kochi and Kumamoto

 

The red lines, Kochi and Kumamoto, have been strongly influenced by Korean and European breeds, particularly Simmental. It is critical for Wagyu breeders to understand the characteristics of each line when cross breeding to produce higher quality Wagyu beef.

The production of Wagyu beef in Japan is highly regulated and progeny testing is mandatory. Only the very best proven genetics are kept for breeding. Realising the value of their unique product, the Japanese Government banned the export of Wagyu and declared them a national treasure. However in 1976, four bulls were exported to the United States and Wagyu were graded up from the American cow herd and was the beginning of a two decade window of Japanese genetics entering North America and filtering through to Australia and the rest of the world to today where Wagyu genetics exist on every continent even though actual numbers remain relatively low in comparison to the more popular beef breeds.

The Tajima line is the most popular of the bloodlines. Although their frame is smaller, they are some of the best genetics for F1 production when it comes to increasing the profitability of you herd.  Keep in mind, wherever you end up sourcing your Wagyu embryos or semen, go for the quality, not the price tag.
