Trent Bridge F115 with 75% Tajima content has superior marbling from leading bloodlines which trace back to Japan.
Trent Bridge F115 is Group D in the Wagyu Fullblood Rotational Programme so has a valuable role in Fullblood breeding. Fullblood Wagyu herds will benefit from F115 semen as progeny derived over high growth and high milk dams will be complemented by the powerful marbling IMF% and also the quality through fineness of marbling that he brings. His pedigree is endorsed by superior carcass breeding predictions from Breedplan. He is in the Top 1% for Marble Score EBV and in the Top 5% for Terminal Carcase Index, and Marble Fineness EBV, and virtually in the Top 10% for light Birth Weight EBV.
Trent Bridge F115 is tested free of F11 and CHS and there is no history of known recessive conditions in his pedigree so he can be used with confidence in seed stock herds.
Trent Bridge F115 semen will be particularly valuable for crossing over conventional base breeds to improve premium eating quality from increased intramuscular fat and improved fineness of marbling. He will be particularly well suited for F1, F2 and F3 production over medium to large size breeds.
He is structurally sound as he has covered cows in rugged range conditions.
Wagyu, in general, produce light calves at birth, but Trent Bridge F115 possesses extremely low birth weight EBVs. Trent Bridge F115 semen will present small calves so can be used to open heifers.
Pedigree of Trent Bridge F115
Sire of Trent Bridge F115 is Itoshigenami TF148. He is the Foundation sire exported from Japan that has the highest 
Marble Score estimated breeding value is still ranked in the top 1%, as is his Terminal Carcase Index too. The value from Kumanami
was not recognised in Japan until more recently when good marbling was attributed to Shigekanenami blood through the maternal side. Itoshigenami and Suzutani are both descendants from Shigekanenami. Sire of Itoshigenami, Shigeshigenami, was line bred to Shigekanenami. Both Itoshigenami and Suzutani have the highest EBVs for marbling amongst their peers for sires and dams respectively.
An ancestor from Itoshigenami’s maternal side, Dai 7 Itozakura, is the most prominent Fujiyoshi sire in Japan known to pass on a large frame from strong growth rate and he was the first Japanese Black sire whose progeny scored above 1k/day on test.
F115's dam, Trent Bridge Wagyu C212, is sired by Kitateruyasu Doi “003” and Michifuku is her maternal great-grandsire. Both of these males are descendants of Yasumi Doi. Yasumi Doi is considered to be one of the leaders of the highest marbling Tajima line with origins in Hyogo Prefecture in Japan. Last year, again, his dam's newest son was the best of his year despite being sired by a moderate marbling bull himself. All of his F1 progeny in the cohort graded AUS-MEAT marbling 9 or 9+ out of Angus dams.
Trent Bridge C212, is still active in the Trent Bridge Wagyu herd at ten years of age and has seven registered Fullblood progeny from natural mating over eight years plus another five as an embryo donor. Her Grandsire is Itozuru Doi TF151 who contributes growth and milk from his Dai 7 Itozakura ancestry and also the Kedaka line through Nishizuru. Trent Bridge C212 comprises 74% Tajima, 16% Fujiyoshi and 7% Kedaka.

Breedplan Estimated Breeding Values for Trent Bridge F115
Trent Bridge F115 Marble Score estimated breeding value is in the Top 1%. His Terminal Carcase Index and Fineness of Marbling estimated breeding values are in the Top 5% for the Wagyu breed and Birth Weight EBV is in the Top 11%.
The Marble Score estimated breeding value is equivalent to an increase of more than 2% intramuscular fat above the average for 2015 born calves.
Trent Bridge F115's premium Fullblood Terminal Index demonstrates his superiority in improving carcass carcase value of his progeny from Fullblood production. The double benefit from Itoshigenami and Kitateruyasu Doi is also conveyed through F1 production.
The BMS score in Japan is directly related to intramuscular fat percentage and has been the prime driver for price of Wagyu beef. More recently, through the use of the Obihiro University digital camera, the economic importance of marbling fineness has been recognised in the market and is reflected in the pricing in Japan. Trent Bridge F115 EBVs for both Marble Score (IMF%) and Marble Fineness are up in the Top 3%.
The carcass EBVs are exceptional and the BLUP analysis in BREEDPLAN for Trent Bridge F115 is principally derived from the 1,769 progeny and 244 carcass records from his sire Itoshigenami TF148. His maternal grandsire Kitateraysu Doi has 2,092 progeny and 70 carcass progeny records in BREEDPLAN.
Wagyu as a breed generally sire small calves at birth but Trent Bridge F115 has the advantage of virtually being in the Top 10% for low birth weight EBV so is recommended for opening heifers.
High Tajima content Wagyu which have high marbling qualities usually have very low milk and growth rates, but EBVs for milk and growth for F115 confirm the contributions in milk and growth rate from Fujiyoshi and Kedaka in the pedigree.
