Shigeshigetani

Shigeshigetani, while virtually unknown in the United States and Australia, represents a very powerful genetic strain of the Wagyu breed.
Shigeshigetani is Sanjirou’s half-brother, but more closely bred than most half-siblings: Shigeshigetani’s mother is Suzutani, Sanjirou’s dam. And Shigeshigetani’s sire is Haruki II (half-brother of Michifuku, sired by the same bull, Monjiro 11550). As noted earlier, Suzutani’s maternal sire was Shigeshigenami J10632, and her maternal grandsire was Shigekanenami, the bull that made the Kumanami line famous. The Kumanami family is known to have extremely potent marbling genes. (There are three key families in the Tajima line: Nakadoi, Okudoi and Kumanami.)
According to World K’s Group, who owns the bull, Shigeshigetani’s progeny have been absolutely exceptional:
3,800 F1 calves fed 540 days [ADG = 2.156 lbs].
90 percent graded 9+ on the Australian scale [grading above 12.9 on a numerical scale, which is three full grades above the highest USDA grade of Prime].
10 percent graded 7-9, on a numerical marbling scale 10-12.9. [On the USDA scale, numbers 7-9 would be considered Prime+ and Prime++.]
