Summary
Biosecurity practices in Danish sow herds were assessed via interviews. While many farms used delivery facilities, some lacked barriers, increasing pathogen introduction risks for weaner transport.
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.
