Biosecurity in 121 Danish sow herds

Area of Science:

• Veterinary Medicine
• Animal Husbandry
• Epidemiology

Background:

• Swine herds face continuous risks of pathogen introduction from various sources.
• Effective biosecurity is crucial for maintaining herd health and preventing disease transmission.

Purpose of the Study:

• To describe and evaluate current biosecurity practices in Danish sow herds.
• To identify potential weaknesses in biosecurity protocols related to weaner transport.

Main Methods:

• A questionnaire survey was conducted with 121 Danish sow units between December 1999 and February 2000.
• Data collected included herd size, health status (SPF or conventional), and specific biosecurity measures for weaner pickup.
• Units were categorized by swine density, herd size (>110 sows as large), and health status.

Main Results:

• Most sow units (71%) utilized dedicated delivery facilities for weaner collection, yet 50% lacked a barrier between loading areas and stables.
• Direct pickup from stables occurred in 19% of units, with truck drivers accessing stables in 10%.
• Stricter biosecurity measures, like quarantine, were more common in large and SPF (Specific Pathogen Free) herds.

Conclusions:

• Significant variations in biosecurity practices exist among Danish sow herds, particularly concerning weaner transport.
• Inadequate biosecurity during weaner pickup, such as the absence of barriers and direct stable access, poses a risk for pathogen transmission.
• Implementing standardized and stringent biosecurity protocols is essential to mitigate disease introduction risks in swine populations.
