Sires

At Grand View Ranch, we have researched sires and dams to create our foundation herd by analyzing EBV and progeny data to create a balanced yet highly marbled pedigree. All of our Fullblood Wagyu are DNA-certified to ensure their Japanese genetics. Here are some of the sires we have utilized in our herd.

 

Michifuku

Michifuku is thought to be the best carcass bull ever to leave Japan. Even with smaller framed offspring, his progeny's carcass characteristics are superb. Michifuku was formerly the number one marbling bull in the U.S. Wagyu Sire Summary, and consistently ranks second in ribeye area (REA) and fourth in backfat thickness (EPD). Michifuku's sire, Monjiro 11550, is linebred to Tajima J105, great-grandsire of Yasumi Doi J10328. Michifuku's dam, Michiko J655635, was sired by Tanishige 1526 and grandsired by Yasutanidoi J472. Yasumi Doi J10328 and Yasutanidoi J472 are considered to be two of the most famous of the Tajima/ Tajiri line.

Yasumi Doi J10328 sired Yasutanidoi J472, as well as Dai 2 Yasutsuru 774, sire of Fukutsuru 068. Yasumi Doi J10328 also grandsired Yasufuku 930, sire of Yasufuku Jr. and grandsire of Takazakura. Yasumi Doi J10328 appears twice in Michifuku's pedigree. This lineage supports Michifuku's high standing.

According to World K's Group data on Michifuku's progeny in Australia:

  • 12,000 F1 calves were fed 540 days [ADG = 2.31 lbs].
  • 85 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].
  • 15 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++.]

Descendants of Monjiro 11550 produced carcasses that sold at auction for $16,000, $18,000 and $21,000 at the 2007 All-Japan Wagyu Competition.

Sanjirou

Sanjirou has the potential to become one of the most influential sires of the Tajima line, having great meat quality, large ribeye area, thick rib and high yields. In the 2006 U.S. Wagyu Sire Summary, Sanjirou ranks third highest in marbling, behind Fukutsuru 068, but ahead of his sire, Michifuku.

Sanjirou is a linebred Yasumi Doi J10328 bull. Yasumi Doi J10328 sired Yasutanidoi J472 and grandsired both Fukutsuru 068 and Yasufuku 930. Sanjirou is out of the prominent Japanese cow Suzutani, who represents one of the most potent bloodlines in Japan. Her great-grandsire, Yasumi Doi J10328, is widely known for his ability to produce excellent meat quality and size. Suzutani's sire was Tanishige 1526, whose progeny test results demonstrate that he has heritable traits with a BMS score +3.1 (above the national average of +2.1) and a yield grade of 72.7 percent.

Suzutani's mother was Suzunami and her grandsire was Shigeshigenami J10632, who, though largely unknown in the United States, has a reputation for producing the best genetics in Japan (see Shigeshigetani). Sanjirou's genetic background suggests that he will have ideal meat production efficiency, with great meat quality, large REA, thick rib and high yield rate.

The World K's Group has proven this genetic prediction accurate, as reflected by the collection of his progeny data:

  • 6,800 F1 calves fed 540 days [ADG = 2.09 lbs].
  • 88 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].
  • 12 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++.]

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++.]

Takazakura

Takazakura is the son of Takaei 1412 (grandsired by Yasufuku J930).

  • 1,200 F1 calves fed 540 days [ADG = 1.87 lbs].
  • 68 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]. 22 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++.]
  • 10 percent graded 4-6. [On the USDA scale, numbers 4-6 would be considered High Choice and Prime.]

Itomichi 1/2

TF Itomichi 1-2's grandsire is Dai 7 Itozakura J65. His mother, Dai 2 Kintou, and grandmother, Ezokintou 1A, are high-grade cows of the Haraharashu line. His great-grandmother, Ezokintou J11961, was awarded Grand Prize at the third Zenkyo (All- Japan Wagyu) competition.

The Dai Ni Kinto line is known for producing consistently large, quality beef. Itomichi 1-2 has been used to increase mature size and growth rate without reducing marbling.

Itohana 2

TF Itohana 2 is a Fujiyoshi Fullblood Wagyu bull, the third in the herd used to increase frame size and improve maternal ability.

The progeny of TF Itohana 2 exhibit excellent maternal ability, good milking ability, and good frame size. He is a male calf of Aino 6 -- a notable fact given that 100% of the carcasses (17 of 17 cattle slaughtered)from the Aino group graded A-5 - the highest grade possible and the average live weight was 1,040 lbs.
