Carcase Data – Bar R 52Y (BRCPG0052) Heterozygous Poll Bull

Since Bar R 52Y (BRCPG0052) progeny have been coming through the Robbins Island Program the profitability and consistency has increased immensely.

Of the 202 progeny (154 steers, 48 heifers) that have been slaughtered:

  • BMS 9 – 26
  • BMS 8 – 92
  • BMS 7 – 60
  • BMS 6 – 21
  • BMS 5 – 3

88% of the carcases have graded BMS 7 or higher

Robbins Island Wagyu Program Steer Analysis

Bar R 52Y steers are currently averaging (over an average of 97% Purebred Wagyu Cows):

  • BMS – 7.6
  • HCSW – 473kg
  • EMA – 99 cm2

The most profitable steer has graded: BMS 9, HCSW 584kg, EMA 109cm2

(*Note: The most profitable heifer has graded: BMS 9, HCSW 494kg, EMA 100cm2)

 

As a comparison, in the same contempory group 2 Fullblood bulls were used (over 100% Fullblood Wagyu):

 

Kanadagene 100 (WKSFPC100), over 3 steer carcasses is averaging:

  • BMS – 8.0
  • HCSW – 439kg
  • EMA – 104 cm2

 

Mirragong 92 (MIRFF0092), over 3 steer carcasses is averaging:

  • BMS – 6.7
  • HCSW – 455kg
  • EMA – 94 cm2

 

In 2017, paddock bred bulls, and Fullblood bulls over the same Purebred and Fullblood Wagyu herd averaged, across 991 carcases:

  • BMS – 6.9
  • HCSW – 408kg

Traditionally, Wagyu animals have tended to marble inversely with weight; higher marbling animals tending to come with lower carcase weights than low marbling animals.

Bar R 52Y steer progeny are producing BMS 7, 8, and 9 carcases at the same average weights. These heavy weight, high marbling animals are extremely profitable.

Below is the average HSCW of 52Y steers at each BMS, and the value of those carcases on a current industry standard grid.

F-1 data from the United States has a similar trend; with long feeding giving heavy weights and high marble scores.

Through the Robbins Island Wagyu program, Bar R 52Y is combining better with certain female sire lines:
