*AUS Progeny Test Program Link Sire Cohorts 4 & 5*

AUS Reg: SYNF23U16

(Link to Breedplan EBVs)

USA REG: FB114851


Sire Stack: Mayura L0010 x Sumo Michifuku F154 x D139 x Michifuku x TF 147 x TF 150 x TF 43 x Kikuhana x TF 40 x Chiyotake 8!!


U16 Chairman is an elite Mayura L0010 son. He displays enviable balance in his EBV profile without the high Birthweights and extreme Mature Cow Weights that are prominent in high genomic sires. He also features a +6 MILK EBV which will make him an ideal mating sire to help correct the lack of maternal traits in many wagyu donors. He is not lacking in the major profit drivers for Wagyu either with a 3.5 MS, 8.5 EMA, and 36 CW (Jan 2 2025)! Chairman is a leading bull on the new Breeder Feeder Index at $625 BFI! It is a bonus that Chairman is Tested Recessive Free! 


532G, his donor dam is one of our best cows in the Synergy herd. She is extremely fertile and raises fantastic calves to compliment her top notch phenotype perfectly. She carries outstanding depth, strength, and width from from front to back and is a great example of the ideal wagyu cow (Pictured below). We have harvested a maternal brother to her (Ribeye pictured below) with tremendous results. This speaks volumes on the potential of this fantastic young sire!  


* Owned in partnership with W8 Ranch



Sire: MAYURA L0010 (AI) (ET)

Mayura L0010 took the Wagyu industry by storm. After topping the Elite Wagyu Sale at $105,000 (a then record). He genomic tested as one of the best Mayura Itoshigenami JNR sons. At the time he was one of the only ways to access JNR genetics. He has since become carcass proven and living up to the hype! His genetics are still in demand with his sons and daughters topping sales in 2022 & 2023! He currently has an elite Breedplan proof of 2.9 MS, 5.2 EMA, and 37 CW on 28 carcasses (Feb2 2024). 

Paternal Grandsire: MAYURA ITOSHIGENAMI JNR (AI)

The “King of Australian Sires”. His semen has sold to a world record $70,000 per straw and live progeny have sold to $280,000! 

JNR is a true once in a generation sire and the foundation of the Mayura Station branded beef program. He has more than 1,000 carcasses in the Mayura herd consistently grading AUS-Meat 9+, with leading ribeye area and carcass weight at a young age.

DAM: SYNERGY F154 CHIYOTAKE 532G (ET)

U16's dam and direct daughter of Sum F154. She carries outstanding depth, strength, and width from from front to back. She has become a major matriarch in the Synergy program, producing high genomic calves from a diverse group of sires. Her elite ability to transmit high performance traits to her progeny sets her in a class of her own. She has progeny from 5 different sires all over $300 SRI and from 4 different sires over $390 on the new Breeder-Feeder Index! Highlighted by U16 at an astronomical $547 Breeder-Feeder Index! 

Maternal Brother to U16's Dam!!

Here is a ribeye from the maternal brother to U16's Dam. This ribeye speaks for itself with incredible marble fineness and even distribution throughout the ribeye. This carcass performance shows the proven carcass ability of this cow family. 

Maternal Grandsire: SUMO CATTLE CO MICHIFUKU F154 (AI)

The elite Sumo Cattle Company bred super sire F154 and Gatekeeper's sire. He is a World K's Michifuku son proven through the Sumo herd where he has averaged an incredible 8.3 MS with a 987.8 lbs HCW on 34 carcasses. He has 79 carcasses on his Breedplan proof producing elite EBVs of 2.4 MS, 5.5 EMA, and 32 CW.
