From: Establishment of a pipeline to analyse non-synonymous SNPs in Bos taurus

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
Australian Jersey × Limousin 1:3 42 21 high + 21 low - predicted % meat4
Angus puberty selection line 3 3 F1 segregating sires
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. 1 Breeding values calculated from Breedplan (Industry database of NZ animals).
  2. 2 Genetic selection for live weight based on [30].
  3. 3 Adjusted % meat from carcass dissection of one side of each animal.
  4. 4 Predicted % meat yield from meat cuts retrieved after slaughter.
  5. 5 [28, 31].
