Takeda Rotational Breeding Program

According to Mr. Shogo Takeda, the 80+ year old Wagyu Master, “Super size, good marbling, good milk production, and good calf raising ability are the keys to success in Wagyu breeding!”  However, too many breeders are still focusing too heavily on marbling, at the expense of other important traits, “Tajima, Tajima, Tajima,” he said, with understated effect…

Under Mr. Takeda’s four-stage rotational breeding plan (see summary graphic below), the emphasis is put on building frame score first, and then marbling.  Mr. Takeda maintains that a breeding program based on his rotation technique is more likely to deliver the best overall profitability in the long term.

For each of the Groups: A, B, C, and D, Mr. Takeda lists the traits in order of priority and significance.

Takeda Rotational Breeding Program

Notes: F1 breeders should use sires from Group B and Group D ONLY. FB breeders should cull non performing female offspring from AxB and CxD matings.
