Discover the Advantages of the White Wagyu.

 Heat-resistant, healthy, and genetically exceptional Wagyu cattle for visionary breeders and investors worldwide. 

A. Heat Resistance

1. Science shows us that black absorbs the heat of the sun, while white reflects it.  Tests in Colombia have shown that a white coated bovine can be 2 degrees cooler internally than a black coated bovine.  This results in better conceptions of white bovines in the heat of Summer.  Black Wagyu developed in Japan have a great heat resistance and so White Wagyu would improve upon that substantially.
2. Pond wading and shade seeking is common among black coated bovines and this leads to less grazing and so less growth and also to hoof rot in the ponds.  Placing your cow on a veterinarians rotating table to have hoof rot treated runs into high veterinary bills.  White Wagyu tend to stay grazing and not pond wade. Saves on the bottom line.
3. Flies are abundant on Black coats almost 3 times as many than on White coats for some reason.  Maybe camouflage but probably because the flies like the heat.  They suck blood and spread pink eye disease.  Less flies results in healthier animals and less vet bills and less blue eye blindness.

B. Marbling (IMF – Inter Muscular Fat)

Genetically, except for the rare luminent/dilution gene causing the lighter coat, White and Blonde Wagyu are Wagyu and identical, so they will marble just as other Wagyu will marble.  Coat color makes no difference to carcass quality.  Once you have Wagyu you have a superior marbling animal compared to other cattle breeds.  Some individuals will vary and IMO generally Black Wagyu have higher marbling than the Red Wagyu while the Reds have finer marbling rather than pencil thick marbling.  Now many of the White and Blonde Wagyu are genetically a combination of Red and Black Wagyu while some are 100% Red Wagyu.   I have tended to incorporate the higher marbling Black Wagyu lines into my Blonde and Whites and so I believe they will outperform the Red (Akaushi) Wagyu and compete well against many Black Wagyu. Generally all Wagyu carcasses tend to grade above USDA grade Prime if on a grain ration and some on grass-fed as well.

C. Heterosis (hybrid vigor)

As stated in B above, many of my Blondes and Whites are genetically a combination of Red (Akaushi) Wagyu and Black Wagyu.  In Japan these are 2 separate breeds of Japanese Brown (Reds) and Japanese Blacks and so the combination of both gives a wider gene pool and this causes the hybrid vigor for superiority over its parents with regard to traits such as growth rate, reproductive success and yield.  In America, due to the Japanese only sending bulls in 1976, breeders were forced to produce Purebred Wagyu (15/16’s up to 99.99% Wagyu). Breeders for about 17 yrs could only use the 4 bulls sent in 1976 to breeding up to Purebred status by using the 2 Black and 2 Red Wagyu bulls.  So “American Wagyu” are composed of both Red, Black, and Red/Black Wagyu as one breed.  The Red/Black being a composition having hybrid vigor of which many Blondes and Whites are composed and so the advantage of heterosis over Black or Red Wagyu.

1. CLV SHIROI TAMAMARU  “TAM”  

Tam, is the patriarch of White and Blonde Wagyu.  Originally, I had thought he was the first white Wagyu but there had been others in the past, since this gene has been in Wagyu from probably the Meiji period in Japan when Simmental were introduced into the Reds as they have the same gene.  However, Tam was the only Fullblood White Wagyu registered bull in the world, that I knew of, and much of his semen has been sold to expand the white and Blonde Wagyu.  Tam’s white Wagyu advantage is not only that he is Homozygous (2 copies) for the luminent/dilution gene being white, but he has super growth and early puberty.  He was big enough at 7 months to mount cows and at 9 months he was fertile so by the time he was 2 years old he had calves being born!  Having Tam genetics in your cattle is a great advantage and his grandsire SOR Unzen is full brother to IWG Umemaru who is the top Red Wagyu marbling bull in the 2017 Sire Summary put out by Washington State University. Plus Tam is genetically ¼ Black Wagyu out of the top marbling Michifuku line!  

E.  Visibility

   White Wagyu are highly visible and offer pure ascetic beauty against a green pastoral background.  The great advantage is being able to easily find them.  I often say a cow looks for a way to die. One of these ways is a heifer may get pregnant early and then run late in gestation and you need to assist in delivery of the calf.  Not often does death occur due to large calves in Wagyu as they usually shell out with small calves.  However, suppose your heifer doesn’t show up with the rest of the herd and is off hiding herself in order to deliver in private.  It could be a rainy dreary dark day or maybe at night.  If she is white you could see her easily and help out, if she is black you can probably find her in a few days by the circling vultures.

F.  Conformation

     White Wagyu being more of the Red Akaushi Wagyu genetics tend to have the more beefy conformation of the reds rather than the big fore and small rears of the Black Wagyu.  Some describe the Black Wagyu as more akin to a black Jersey in looks. So White Wagyu look more like a typical beef breed and many prefer that look.

G.  Polledness

Having cattle without horns is most beneficial, not only for safety for yourself but also the cattle. Cattle that have horns know they have them and keep cattle without horns away from feed and hay.  Once I had some Scottish Highlands running up the cattle chute and the horn of one went up the rectum of the one in front of her and that wasn’t good.  Fullblood Wagyu are mostly horned, and most polled Wagyu have gotten the Celtic Poll from a cross with Angus in the past.  In order to get Polled Purebred White Wagyu I have had to breed down from my Fullblood Whites to Purebred Polled Blacks and Blondes and in 2024 got my first Heterozygous Polled Purebred White Wagyu.  I believe the little heifer is the first Polled Purebred White Wagyu in the world. I do have some Blondes that are polled out of the black Bar R Arimura line and out of the famous Australian bull Perfection.  These are great lines and soon there will be high demand as with other breeds that have gone to polling their animals naturally instead of the mess of dehorning.
