Wagyu Breeding
There are Five different categories when it comes to breeding with Wagyu and each category works on a percentage.
Fullblood wagyu (100%)
When the offspring is bred from a sire and dam that originates from Japan and whose pedigree shows no indication of crossbreeding, they are considered to be original. In South Africa we have very few Fullblood Wagyus, therefore many breeders import Fullblood Wagyu semen and embryos from Australia and the USA.
F1 (First Cross) Wagyu (50+%)
When a Fullblood or Purebred bull is mated with a base female, from any breed, to produce offspring that is more than 50% Wagyu.
F2 (Second Cross) Wagyu (75+%)
When a Fullblood or Purebred bull is mated with a F1 female, to produce offspring that is more than 75% Wagyu.
F3 (Third Cross) Wagyu (87+%)
When a Fullblood or Purebred bull is mated with a F2 female, to produce offspring that is more than 87% Wagyu.
Purebred Wagyu (93+%), also known as an F4 (Fourth cross)
The F4 is when a Fullblood or Purebred bull is mated with a F3 female to produce offspring that is more that 93% Wagyu. Purebreds can never be bred up to Fullbloods again.
