About White and Blonde Wagyu Cattle

White and Blonde Wagyu Cattle are extremely rare due to the "luminent" or dilution gene found in some Red "Akaushi" Wagyu and maybe a few black Wagyu. A luminent gene in Reds or Blacks is considered "hidden" as those heterozygous lumen cattle look just like traditional red or black Wagyu yet they carry the one gene. Others where the one gene is "visible" the Wagyu are various shades of blonde but mostly ash blonde. Those Wagyu that carry two lumen genes or homozygous luminent are always a White or Cream colored Wagyu. Very similar to the white Charolais breed except more docile.

The lighter coats of luminent Wagyu reflect the sun's rays while darker coats absorb the sun's rays raising the temperature. So the lumen Wagyu stay cooler in the heat externally and internally. It could make up to a 2 degree difference internally as purported by Colombian tests. This can make a difference in conception rates especially if you buy high dollar embryos.
Plus lumen Wagyu can lower vet bills as darker coated animals like to escape the heat by wading in ponds where they can catch hoof rot. Less pond wading > less hoof rot > less vet fees.
Flies, the carrier of pink eye disease, seem to alight on dark hided animals mostly. Probably because of the higher heat generated but maybe as camouflage. Regardless, less flies > less pinkeye > less vet bills.

White and Blonde Wagyu Cattle are very rare. In fact, were it not for the luminent gene being hidden in red and black colored luminent cattle, it might have been eradicated completely. Red and Black Wagyu are the most common and anything different, some may have thought the neighbor's bull had jumped the fence, and so many white or blonde Wagyu were slaughtered. However, DNA traces these animals right back to their Japanese origins.
The only semen out there from a White Wagyu bull as of Dec. 2023 is of CLV Shiroi Tamamaru and he will give a luminent gene to all his progeny. Mostly on blacks the calves will turn to ash blondes and reds to a reddish tan blonde, though some may be a hidden and they are reds and black luminents.
We, White Wagyu visionaries, see the extreme heat and drought arriving in many areas and recognize the need for heat tolerant Wagyu to improve the beef in hot areas north and south of the equator. Now, we are increasing our numbers and will have more visionaries and cattle. Now, is a good time to catch this wave and ride it into the future.

Matriarch of the White and Blonde Wagyu is grand champion Red/Black heifer GVW Michifuku 93014 USAFB21014. "Gypsy" was purchased online at the Denver sale after the show. She was bred to Rowe Tamamaru Jr. a fullblood Red (Akaushi) bull that was red colored and carrying the hidden luminent gene. Their offspring was Tam the white Wagyu bull whose semen is being used extensively to propagate the white and blonde Wagyu. Gypsy continues to produce beautiful white and blonde calves.

Tam was a beautiful white calf but didn't remain a calf very long. All the calves in the above pics are Tam's progeny except in the pic of "Why white..." The white heifer on the right is sired by Tam's blonde son, Daku. Imagine, say, you had a herd of fullblood Black Wagyu in Texas and they were suffering in heat and drought. You could use Tam's semen and begin crossing over to a more heat tolerant Wagyu beginning with a first crop of Blondes and then later Whites would begin to materialize. The ultimate genesis of using the luminent gene will be White Wagyu cattle. Just like the white Charolais, how many know the original color of Charolais was red?

Tam is the fastest growth Wagyu bull I have ever had. Partly due to his mother Gypsy having a fantastic udder producing good milk but mostly due to genetics. Here is a pic that shows a perfect comparison of the two fastest growth bull calves one is a red that is 1/4 Tajima and 3/4 Akaushi lines just like Tam is and he was the fastest growth bull born in 2017 and he is next to Tam the fastest growth bull in 2018.
