We offer semen on our top sires.  All sires are tested free of the genetic recessive disorders.  We attempt to produce bulls that we believe have the potential to be better than their own sires and dams because of complementary matings of top animals, and which provide a variety of genetics that will fit many different breeding situations.

All of our published semen prices are “per straw” and assume a minimum order of 10 straws, although we will accept orders for lesser quantities with a small order processing fee.  Discounts available for orders of 100 straws or more.    

Please call Jim Long to discuss your needs.

GAF Ichutani 10D (FB26683)  –  100% of this bull’s genetics consist of 1/4 each of four famous foundation animals.  This was achieved through a double breeding of Suzutani, the most famous of female Wagyu to leave Japan.  Directly sired by Stonyrun ID 151 Ichiro 1, which is Itozuru Doi mated to Suzutaka 2 (Takazakura/Suzutani).  Out of a cow sired by Michifuku out of Suzutaka 2 (Takazakura/Suzutani).  Genetics consist of high marbling Tajima lines with the highest marbling and finest marbling Fujioshi-line bull, which is also recognized for rapid early growth and size. 

  • 25% Michifuku
  • 25% Itozuru Doi
  • 25% Takazakura
  • 25% Suzutani

While a medium-framed adult bull, he exhibited outstanding early growth, with a weaning weight of 556 lbs. and a yearling weight of 850 lbs. according to his breeder, Golden Age Farm.  SCD/Tenderness is AA/7.  Stored at Elgin Breeding Service in Elgin, Texas.  $25 domestic use, $40.00 for CSS for embryo production for worldwide export, and directly exportable to most countries other than the European Union.

KR Mich 400-351 (FB7646) – Sired by the great Michifuku, believed by many to be the best overall carcass bull to have ever left Japan, out of a cow sired by Kikuyasu-400, the largest Tajima-line bull to ever leave Japan, who was in turn out of the Yuriko-1 foundation dam.   So this bull’s pedigree contains only three famous foundation animals:

  • 50% Michifuku
  • 25% Kikuyasu-400
  • 25% Yuriko-1

This bull has sired many grand champions and reserve grand champions at Wagyu shows, and seems to have a propensity to throw heifer calves according to his breeder, Kay Ranch.  Our experience with this “heifer vs. bull calves ratio” matter is limited to calves born in the spring of 2018, during which 23 calves were produced from this sire, 13 of which were heifer calves.  So this sire did in fact produce a higher ratio of heifer calves to bull calves for us for this very limited data set, which provides a small degree of confirmation of what this sire’s breeder, Kay Ranch, has stated was the case.  SCD/Tenderness is AA/5.  Stored at Elgin Breeding Service in Elgin, Texas.  $25 domestic use, $40.00 for CSS for embryo production for worldwide export, and directly exportable to most countries other than the European Union.
