This is a son of the breed leading sire Mayura Itoshigenami JNR. Itoshigenami JNR semen is currently not available on the market and recently 6 straws sold in the 2020 Mayura Sale to high of $68,000 per straw! Mayura Itoshigenami JNR carries elite high reliability EBVs because of his superior carcass data. In Mayura Station herd he has averaged a 9.05 MS, 448 kg (986 lbs. ) HCW, and 109.0 cm2 (16.9 in 2) EMA on an astounding 805 carcass harvested at just 26 months. This makes Tyddewi N4431 a unique combination of elite Mayura Station and Westholme bloodlines. Through his dam Westholme J0147, he receives growth and carcass traits from the top Westholme lines of Yoshifuji 8 and Yamafuji. These are two high Shimane influenced (throgh Dai 7 Itozakura) Westholme foundation cows. The combination of the growth of these Westholme lines with the carcass traits of Itoshigenami JNR produces the massive genomic figures of +2.4 for MS, +5.2 for EMA, MF +.40,+35 for Carcass Wt, and +$269 Self Replacing Index.
