Correct ventilation will ensure the pig’s environment is optimal for growth, regardless of the fluctuations in outside weather and conditions. Maintaining adequate temperature and humidity will help keep pigs healthy & thriving. It is essential that weaned pigs are housed in a draught free environment. Smoke bomb tests can help visualise air flow currents. This can help to identify any draughts or areas of stagnant air, particularly in the parts of the pens where the pigs typically lie Fan louvers & blades should be routinely cleaned to maximise ventilation efficiency #devenishnutrition
