Internal Biosecurity on Pig Breeding Farms
Internal biosecurity is based on the measures implemented on a breeding farm with the purpose of reducing the chances of penetration/spread of already existing pathogens to animals or other sections of the facility.
The internal biosecurity plan of a pig breeding unit operates in four distinct sectors where the “all-in, all-out” principle must apply, general and specific hygiene rules must be followed and the spread of pathogens due to working staff must be prevented.
In the breeding sector, sows are prepared for artificial insemination within 4-6 days.
In the gestation sector, sows are accommodated in groups based on their gestation period until this reaches 114 days. Prior to the transfer, the pregnant females are dewormed and washed in order to prevent the spread of pathogens in the maternity ward.
In the maternity ward/sector, sows are housed individually in farrowing pens. In order to prevent the transfer of pathogens, the transfer of piglets from one pen to another is not recommended.
In the nursery sector, the transfer of piglets is completed around the age of 42 days and at a weight of 12-13 kg. Pigs are kept here until they reach an average weight of 25-30 kg. Each compartment of the nursery sector is simultaneously populated and depopulated.
Internal biosecurity measures are important for maintaining the health of the entire herd. They reduce the need for employing antibiotics and help lower the farm’s production costs.
