- T for Topigs Norsvin

- The Fifth letter refers to mothers mother
If you started up as a Topigs Norsvin nucleus management and now inseminate old sows with other genetics, the sows must be registrated as "unknown race". These herds are called "InGene"-herds.
In PigVision you can setup the breeds as below:
There are different constellations regarding to how come you are a InGene-herd and there are several breeding code possibilities. The possibilities are described below:
ZigZag-herd: Starts with other genetic sows and are inseminated with Topigs Norsvin boars:
...Afterwards it changes between TLLZX and TZZLX.
As a nucleus management herd with ZigZag the TN70 animals are referred to as:
- TLLZX a zigzag sow inseminated with Landrace father, Z-line mothers father and hybrid mothers mother
- TZZLX a zigzag sow inseminated with Z-line father, Landrace mothers father and hybrid mothers mother
After a while a InGene herd only has TZZLX and TLLZX animals.
Landrace-herd: the herd has landrace nucleus management but are changing to Topigs Norsvin:
...Now it is a "purebred" Landrace.
