Nucleus management (Kernestyring
®) is an internet-based tool for controlling the breeding of a herd, which was developed by the Pig Research Centre. With nucleus management (Kernestyring
®), you receive information on the distribution of the genetic level of core sows. This enables you to select the best gilts and sows for the production of pure offspring and the rest for the production of young crossbreed pigs.
The nucleus managmenet programme should be supplemented by using artificial insemination boars. The main reason for this, being the use of different artificial insemination boars with a respective high breeding index, makes the use of several different ancestries possible. This would not be the case when using an individual animal with a high index value. As a result, the certainty of the average index level for boars is increased considerably. In addition, the index value of artificial insemination boars generally lies above the value of herd-boars.
The main breeding strategies for the nucleus breeding programme are
nucleus herd and a
zig-zag crossbreeding strategy.
