Section 2—System Information

The objective here is to draw a flow chart on a separate sheet of paper that describes the flow of pigs through the system that this site is a part of. Inventory, flow of pigs-including replacements and PDCoV status at each sister site- should be indicated. See page 13 for an example.

Section 3—Site Map

The objective here is to draw a map of the site on a separate sheet of paper in as much detail as you can (with the interviewee). Include the location of: rooms that broke first with PDCoV, arrows indicating room spread of PDCoV, different production areas (e.g., “Room 5-6-Nursery Isolation”), entry areas (showers, changing rooms, fogging rooms if applicable), entrance and exit doors, feed storage areas, parking, composting or deads area, manure storage and loading and unloading areas for pigs. See page 14 for an example.

This rest of this form should be completed through a personal interview with the individual who has the greatest degree of knowledge of the information asked in each section (e.g., owner or herdsman). Ask each question as it is written and answer all questions. If a question is not applicable, write or check NA. If a respondent does not know the answer, write or check DK and try to get the answer at a future date. A separate form should be completed for each site.
