| Breed | Number of Animals | Distribution and Selection Method |
| Angus | 49 | 23 high + 26 low - Breeding value1 |
| Hereford | 70 | 59 high + 11 low - Breeding value1 |
| Simmental | 30 | 26 high + 4 low - Breeding value1 |
| Angus weight selection line | 40 | 20 high + 20 control - Genetic selection2 |
| NZ Jersey × Limousin | 3 | 3 segregating sires which were backcrossed to Jersey or Limousin dams to produce the progeny below |
| NZ Jersey × Limousin 3:1 | 21 | 10 high + 11 low - Carcass dissection3 |
| NZ Jersey × Limousin 1:3 | 42 | 21 high + 21 low - Carcass dissection3 |
| Australian Jersey × Limousin | 3 | 3 segregating sires which were backcrossed to Jersey or Limousin dams to produce the progeny below |
| Australian Jersey × Limousin 3:1 | 21 | 11 high + 10 low - predicted % meat4 |

| Angus puberty selection line (AGE+) | 7 | progeny from 2 sires (3 high + 4 low for yield)5 |
| Angus puberty selection line (AGE-) | 18 | progeny from 2 sires (9 high + 9 low for yield)5 |
1 Breeding values calculated from Breedplan (Industry database of NZ animals).
2 Genetic selection for live weight based on [30].
3 Adjusted % meat from carcass dissection of one side of each animal.
4 Predicted % meat yield from meat cuts retrieved after slaughter.
