The process of preparing and storing seminal doses is key for obtaining maximum fertility and profitability from a boar. The sperm quality of the male is certainly a decisive factor, but posterior alterations till insemination time can be prevented and/or controlled.
A critical point in the preparation of seminal doses is any decrease of the optimal quality and fixed durability of the semen doses produced. For that reason, any factor that may alter the capacity to produce doses, prolificacy and fertility rates and/or imply the introduction of pathogens from boar studs into the farms should be controlled.
Therefore, the focus of attention should be placed on the laboratory (materials, water quality, temperature and extender), staff, biosecurity, hygiene and disinfection, as well as animal health. Control of the doses produced is lost after departure from the stud facilities. It is thus essential to achieve maximum quality at such moment, so any possible stressing factor occurring before artificial insemination in the farm can be buffered.
