Why Wagyu?

How it's tested.

Our Seedstock Genetics


This test is designed to assist in the selection of cattle that show a genotype that produces a superior fat composition. Stearic acid, which corresponds to the amino acid Valine (VJ), makes deposited fat harder. Oleic acid, which corresponds to the amino acid Alanine (A), makes deposited fat softer, which Prescribed Genomics states is more palatable to the Japanese market. There are three possible genotypes for SCD, these are AA, VA and VV. AA is the preferred type. ** The Tenderness Marker is scored from 1-10 with the higher the number, the more tender. The assigned score is based on the best estimate of the tenderness value of this genotype given the information available.

 Why Is AA10 So Special?

In the Wagyu Breed the preferred fat type is AA. Of all the Wagyu in the USA, only 18% test out as AA fat type.  Of those that test out as the AA fat type, less than 1% will test out with a tenderness score of 10.  If you now take away any of those that test out AA10 and are free of known genetic disorders, you are looking at a very small group...less than a couple of dozen.

 As is the industry standard, an AA-10 carcass is valued at $10,000 on the rail (hanging in the locker plant, ready to be cut up). At Milburn-Kroh American Wagyu, the price structure is simple. My carcasses all have a DNA verified carcass score ranging from A-1 to A-10. I will not sell a carcass that scores less than A-5. An A-5 carcass will cost $5000 or $2500 for a half. The price goes up along with the tenderness score. An A-6 carcass will cost $6000, A-7 costing $7000, up to A-10 costing $10,000.

     I will sell nothing less than a half carcass. Rather than sell you a 1 lb ribeye steak for $130, I will sell an A-5 half weighing approximately 350 pounds for $2500 ($7.14/lb + approximately $1/lb processing = $8.14/lb in your freezer). Do the math. It’s a no-brainer.

Milburn American Wagyu

Our Five Freedoms for Livestock

At Milburn American Wagyu, our main focus is on developing high-quality Wagyu genetics. For years, we ran Angus cross cow/calf pairs. We still maintain a handful of quality Angus "Super Mommas" in our F1 and recips herds. The health aspects and amazing taste of Japanese Kobe style beef along with the docility and calving ease of the animals led us to transition to the Wagyu breed.

Due to a unique genetic variance (allele), Wagyu fat melts at a lower temperature making the beef taste buttery and rich. It also contains a higher ratio of mono (good) to saturated (bad) fats. Within the Wagyu breed, there are three allele pairs cattle can have: VV, VA, and AA. The AA gene yields a lower melting point and healthier fat of the three types. In our program, we are highly focused on SCD AA animals.

We will continue to sell Angus-cross steers until the Wagyu F1 steers become available. We are currently taking orders for 2023. 2022 is sold out.  We will are now selling Wagyu seedstock genetics (semen and embryos). Watch our Facebook page for details.

Scores PRIME every time

Our Beef Quality Assurance Training instills in us how we raise our livestock. We uphold and honor the following five freedoms for livestock. 

Wagyu is arguably the best and most expensive beef money can buy. With its exceptional marbling, superior tenderness and exquisite flavor, it’s no wonder Wagyu is the pinnacle of the beef world.

Through careful genetic selection and feeding, Wagyu producers can create an experience for connoisseurs unmatched by any other beef. From executive chefs to the weekend barbecue fan, Wagyu offers a level of quality that can be enjoyed by everyone. And with its proven health benefits, choosing Wagyu isn’t just a treat for your taste buds, it is great for your heart as well.

Wagyu beef really does take red meat to a level beyond Prime. Try it today.

Born 3.08.2020. AA-7 & Defect Free.  Fullblood Black Wagyu Bull.

This bull is sired by Sanjiro 5U, who comes directly from Sanjiro 3 (extremely rare), who led the 2017 Washington State University sire summary for marbling.  5U's sire side has a combination of Michifuku and 2x Suzutani (potentially the most famous cow in the breed), along with Kenhanafuji, the highest-selling Wagyu bull of all time.  The bull's dam CX4 MS SANJI 447E has a pedigree about as stacked as you can get.  She brings more Michifuku, both top and bottom, as well as more Suzutani!  In the pedigree, you'll also find Kikuyasu - the largest bull ever imported from Japan, weighing in at 1,980 pounds, as well as a full brother to TF151. According to the January 2022 BREEDPLAN, 5U JR is in the top 10% for 200, 400, 600, Mwt, Cwt, SRI Index, and WBI Index. He is in the top 5% for EMA and top 3% for RBY. This bull is AMAZING! Tag 85.

Born 11.7.2018. AA-7 & Defect Free. Fullblood Black Wagyu Cow.  

Her dam, is a very unique 100% Tajima cow.  She has a beautiful udder with extra milk flow.  “Toshi” is a very well-balanced female with her deep flank, huge bold spring of rib, strong top and extra muscle shape throughout.  Her sire, LMR Toshiro 1-3 is a Trait Leader among all Wagyu Sires outside of Japan.  With high accuracy, he ranks in the Top 1% of the breed for Carcass Weight EBV (+60) according to the October 2019 BREEDPLAN Report.  Tag 106.


Born 4.30.2021. AA-4 & Defect Free.  Fullblood Black Wagyu Heifer.

Her sire brings in the nationally famous Kay Ranch genetics for maternal strength, along with Itomoritaka known as the best cow producing sire in the Wagyu breed per the Blackmores in Australia. Her dam brings LMR Toshiro 1-3 who knocks the top out of Carcass Weight EBV at +60. You will also find Itoshigefugi known for size among the foundation sires. “Macho” has the genetic potential to produce large foundation dams with exceptional milking ability and gentle temperament. Time and data will tell the story. Tag 92
