Using three pig breeds in a terminal crossbreeding systemThe commercial pig producer must decide where to buy his breeding stock and what his replacement rate per year will be. The latter is necessary in order to maintain the most efficient age structure in the herd. The F1 gilts benefit from the fact that they are hybrid and as a rule outperform the average performance of the two pure breeds/genotypes, particularly with regard to maternal traits. The introduction of a third pig breed (pure or composite) and thus a terminal sire line in this breeding programme enhances the further exploitation of heterosis. This pig breeding plan is most commonly practiced in South Africa and probably worldwide. However from a practical point of view the following aspects require consideration: The need to budget well and accurately in order to receive and pay for the supply of replacement stock at regular intervals.The introduction of breeding stock from outside increases the health risk in the pig herd and could also lead to additional problems. Special attention should be paid to bio-security and health.In essence the genetic supplier of pigs, provides the ingredients (F1- gilts/motherline semen and terminal semen), the management and nutritional guidelines, protocols and back-up service, and the commercial pig producer follows the recipe to produce lean pork meat.Excerpt from: Modern Pig Production
