This is our Friday rubric: every week a new Science Page from the Bob Morrison’s Swine Health Monitoring Project. The previous editions of the science page are available on our website.
This week, we are sharing a note from Dr. Cesar Corzo who is starting a study on sow herd filtration and recruiting herds. The MSHMP mission goes beyond collecting data regarding swine herd disease status, it also includes research projects that are relevant to the swine community.
Objectives of the study
The objectives of the study are to describe the occurrence of PRRSv in the filtered sow herd population within MSHMP and to assess the associations between farm-level factors and the introduction of PRRSv into filtered sow herds. The results of the study may guide practitioners and veterinarians to modify their management and biosecurity practices in filtered sow herds.
Who can enroll?
All filtered sow herds of MSHMP participants will be eligible for the study. The database will be used together with the PRRSv incidence measure to understand occurrence of PRRS before and after filters were installed. A survey has been created to collect farm specific data such as:
- Date when herd was filtered
- Type of ventilation (negative or positive)
- Back draft prevention methodology
- Type of pre-filter and filter
- Pre-filter and filter replacement frequency
- Number of barns and load outs
- Audit frequency
- Frequency of gilt introduction and weaning events
- Regional density
