Managing pigs in summer heat


It is important for pig producers to do all they can to keep sows cool in warm weather. Two or more consecutive days of temperatures greater than 18°C, around weaning and during late or very early lactation, can result in a reduced farrowing rate. 
Shades, wallows, sprinklers can all help. Wallows are a key method to help outdoor pigs cool down in hot weather and help prevent heat stress. 
Good management of wallows is vital and includes: making the wallow big enough for twice the number of pigs it will serve, replenishing wallows with water in dry periods and ensuring it is more liquid than mud – aim for ‘emulsion paint’ consistency.

CO2-controlled ventilation

Pigs give off varying amounts of carbon dioxide depending on number, weight, activity, health status and feed conversion; this varies over the course of 24 hours.
If the ventilation rate is wrong, heating will also be wrong and the air quality will be suboptimal, leading to a depression in productivity and increased risk of disease outbreak. To hear more about CO2 controlled ventilation and how heating costs can be reduced, watch Niels Veng’s presentation from our Innovation Conference here
