Sire trends at Feeder Markets 2006 – 2007

Following is a Top 10 ranking of the leading FB AI sires based on progeny sold at 11 major feeder calf sale yards in the Hokkaido, Aomori, Miyagi, Tochigi, Gifu, Shimane, Kumamoto, Miyazaki, Shimane, Kagoshima prefectures. This is representative of the national market. Data collection period: December 2006 – August 2007.

Average Bloodline Composition 6 Calf Market Sires 2006 – 2007

Analysis:
Modern Japanese feeder sire selection is directed by the need to increase growth and carcass weights while maintaining good marbling.

  • Kedaka line sires dominate, largely due to the consistent influence of Hirashigekatsu in delivering superior marbling and excellent carcass weights.
  • Itozakura line sires take second ranking, a result of the powerful influence of Kitaguni 7/8 in delivering excellent growth and superior marbling.

The trend is towards to consistent achievement of heavier A-4 carcases at reduced DOF, reduced cost and increased profitability. The parallel trend is away from sire selection for 100% A-5 outcomes, achieved with high Tajima bulls likely to deliver lesser carcass weights and growth rates.

 

 

 

 

 

Best Japanese FB Wagyu Bulls 2006 – 2007

Note: Progeny test results shown below are compiled following the Indirect Examination process detailed above under ‘Japanese AI bull selection’. Because the data is typically collected from feeders slaughtered at about 24 months of age, marble scores are lower than would occur for ‘finished’ feeders slaughtered at 29-31 months.

Carcass Competition Results & Trends 2006 – 2007

Scrutiny of quality by bloodline is intense in Japan and also reveals modern breeding trends, as the following carcass competition data illustrates.

A.) Tokyo Meat Market 2007

This competition assessed 2,674 carcasses.

Analysis:
Hirashigekatsu (Kedaka) takes a dominant position in both weight and marbling categories and will be continuously used for the feeder cattle production. New generations of sires by Hirashigekatsu are now available in Japan. Bloodline composition of Sires at this 2007 carcass competition features a greater Tajima emphasis.

B.) Osaka Meat Market 2007

A summary of carcass competition results held at Osaka Meat Market over 904 carcasses.

Analysis:

Greater Tajima bloodline emphasis results from the geographic location of Osaka in Tajima breeding heartland. Nonetheless, Hirashigekatsu (Kedaka) has again been employed to boost carcass weight. Marbling is maintained by the combination of high marbling bloodlines from Kitaguni 7/8 and Yasufuku 165-9.
