JAPANESE ROTATIONAL BREEDING PLAN (Known as Modoshi Kohai) For breeders who are influenced by this traditional Japanese rotational breeding plan, promoted by well-known Japanese Wagyu breeder Shogo Takeda, an updated version follows – including our battery of Lone Mountain Sires. The system consists of sires being divided into groups (either Marbling or Frame). There are just two rules: First – Cows sired by “Frame” Sires should be bred to “Marbling” and Second – Cows sired by “Marbling” Sires should be bred to “Frame” Sires A sire is determined to be of one of these two groups by a straightforward and effective assessment tool: the Japanese 16-16 Analysis. First, the combination of key regional Wagyu strains is identified over four generations in an individual’s pedigree. Second, the combinations are analyzed for those strains’ likely outcomes. With that analysis in mind, successful breeding choices are made clear. Kenichi Ono puts forth in his book 100 Elite Wagyu Sires in Japan (Vol I-III) a definition of “successful breeding”, which is echoed by Takao Suzuki and Mike Buchanan at the Australian Wagyu Forum: 1. Understand the characteristics of each strain 2. Plan combinations to cover weak points of individual strains 3. Don’t over-emphasize one strain. 4. In this way, one can use the 16-16 analysis to get a sense of the outcome of breeding one animal to another. As a point of reference, the following major strains and sub-strains of Japanese Black Wagyu commonly exhibit the following traits: • Okayama (Shimomae): Large Frame Sub-strains: Shimomae, Kiyokuni, Fujiyoshi, Itozakura • Shimane: Outstanding Structure, Strong Length, Depth, and Good Milk Sub-strain: Itozakura
