Ventilation systems are intended to help provide optimum living conditions for pigs. A well-managed, efficient ventilation system effectively draws fresh air into a building and removes stale air containing a proportion of microbes, dust harmful gases and water vapour. Inefficient ventilation is detrimental to pig and health performance (particularly on hot days) and costs more to run.
The report from the AHDB Pork Ventilation Project, which was part of the Pig Health Improvement Project (PHIP) funded by Defra, gives some practical examples of how improving ventilation systems can improve production
Information and guidance
Ventilating Pig Buildings Guide
The pig building ventilation guide aims to help producers provide optimum living conditions for pigs, thereby improving production efficiency, through a better understanding of the principles of ventilation and types of system available. Download the guide or email firstname.lastname@example.org to request a hard copy..
A number of videos about pig unit ventilation are available to help pig producers identify ventilation-related problems and, more importantly, provide practical solutions; they are presented by John Chambers of J C Consulting, who has been trouble-shooting problems caused by poor ventilation for many years.
