Where does one begin and end with regards to talking about the Queen of the Breed, Suzutani. Suzutani was a direct import from Japan along with Okutani and Rikitani. She has gone on to establish herself as the most genetically influential cow of the Wagyu breed outside of Japan. She has produced breed leading sires in both the US and Australia. This long list includes sires such as Sanjirou, Shigeshigetani, Kanadagene 100, TWA Shikikan, and the US carcass trait leader, Sanjiro 3. Both the US and Australian sire summaries are dotted with her grandsons and great grandsons. Suzutani has put a powerful stamp of quality carcass traits into her offspring, particularly with extensive marbling and huge rib eye area. Because of this, feedlot operators the world over specifically seek Suzutani influenced cattle. If breeders are looking to capitalize on the specific trait of marbling that is unique to Wagyu, then you need to be pursuing Suzutani genetics.
Sanjirouand Shigeshigetani are showing their fantastic carcass quality traits in well-known herds around the world. In the Lone Mountain Ranch program Sanjirou and Shigeshigetani are averaging an impressive 31.48% IMF (23 carcasses) and 30.88% IMF (58 carcasses) respectively. Marble Ranch has reported that Shigeshigetani has averaged 35.63% IMF, 16.27 In2 REA, and 1008 lbs HCWT in their program. In Australia at Mayura Station, Shigeshigetani has averaged an 8.33 AUS-Meat MS, 100.33 cm2 (15.55 in2) EMA (10/11th rib), and 416 kg (917 lbs) HCWT on 12 carcasses. Sanjirou has averaged a 8.23 AUS-Meat MS, 96.28 cm2 (14.92 in2 ) EMA (10/11th rib), and 406 kg (895 lbs) HCWT on 149 carcasses at Mayura Station. These figures rank Sanjirou and Shigeshigetani at the top end of all three of these leading herds.
Also, in Australia at Mayura Station, the next generation Suzutani sire Mayura Herald is performing well. He has produced 89 carcasses with an Average MS of 8.52, Ave CWT 425.9kg and EMA of 86.96 (10/11th rib) Ave DOF 281. He now has 108 carcasses in Breedplan he has a leading +2.1 MS EBV with 92% reliability.
The Suzutani’s are continuing to show their genetic superiority through next generation sires Longford 004 (LFDFY0004) and Longford 005 (LFDFY0005). These standout sires are full brothers sired by Kitateriyasudoi 003 out of a Michifuku x Haruki x Suzutani dam. They both have marble score EBVs over +2.0 and eye muscle area EBVs over +4.5! Their proofs are backed by genomics and carcass data producing reliability over 70%.
The new standout proven sire from the Suzutanis in the Longford herd is Longford Mr Awesome!He has leading Breedplan Indexes because of his all-round balance of MS, REA, CW, Milk, and Growth. He is a TF 148 x TF 147 x Kitateriyasudoi 003 out of a Michifuku x Haruki x Suzutani cow. He goes back to his 003 grandmother who the same breeding as Longford 004 and 005. His GEBVs currently include a +2.8 MS, +4.9 REA, +17 CW, and $301 SRI! He is backed by a nice 55 carcasses producing a MS reliability of 92%.

In the PDF is a list of the leading proven Wagyu Sires over 80% reliability for Marble Score. We use 80% reliability because it is a well-known marker for carcass proven sires to give significant confidence in the accuracy of their EBVs. As you can see, Suzutani maternal line sires dominate the high MS leaderboard. This illustrates perfectly the unique ability of this cow family to transmit marbling and carcass quality!
