Sire: World K's Yasufuku Jr
Reg. #: FB14930
Birth Date: Oct 2012
Cane Code:

LMR Yasumasa 2428Z represents the mating “nick” that Lone Mountain has uncovered, combining the abundance of marbling from WKS Kitaguni Jr with the fineness and richness of marbling from WKS Yasufuku Jr. The grandsires on both sides of the pedigree, Yasufuku J930 and Kitaguni 78, have been identified, admired and revered by Kenichi Ono – naming them #1 and #3 greatest Wagyu in Japan, respectively. We are privileged in the West to have proven sons of such caliber from these two major sires of the Black Wagyu breed. The coupling of the two often results in extraordinary animals – and we at Lone Mountain have seen the signs of achievement on a spectacular scale.

Even though 2428Z is a Carrier of CL-16 (like his sire, WKS Yasufuku Jr, and his grandsire, Yasufuku J930), he shows great promise, and we have been using him as a cover bull with great success. A Carrier animal shows no physical symptoms of disease and appear normal – two copies of the recessive allele must be present (an Affected calf) before an animal shows symptoms of the recessive disease. As long as the heifers and cows that he covers are not CL-16 Carriers, there is no possibility of producing an Affected calf.

Although not yet reached his prime, 2428Z has a bright future ahead of him as evidenced by the result of the ribeye image of his half-sib LMR Yasufuku 3487A (also out of Kitaguni Jr dam), showing an outstanding IMF of 44.89%. 3487A was also a Carrier of the CL-16 allele. We anticipate great carcass results to be reported from the abattoir from 2428Z.

LMR Yasumasa 2428Z has the ideal set of BREEDPLAN figures as a heifer bull. He is in the TOP 1% for Birth Weight EBV (-2.6), top 4% for Rib Fat EBV (+1.4) and Rump Fat EBV (+2.3) and above breed average for Marble Score.

LMR Yasumasa 2428Z has been tested Free for the F11, B3, and CHS recessive genetic allele. As mentioned above, he is a Carrier of CL-16. His SCD result is AA and a Tenderness Score of 6.
