However, the level of efficiency that can be obtained is set by the genetic merit of the breeding herd. The genetic merit of the breeding herd is established by the crossbreeding program used and the introduction of new seedstock either by purchasing females or boars. The most popular crossbreeding programs have been rotational programs that produce replacement females so that only boars need to be brought into the herd.
Farmers can use other more specialized crossbreeding programs, only purchase boars as well.
When purchasing new herd boars, follow a specific plan to ensure a trouble-free experience that will add genetically superior animals to your herd. Identify potential suppliers. Select the boars. Negotiate the sale. Introduce the boar to the farm.
