Prolonged exposure to sun and heat can result in stressed pigs and reduced performance. Just like when you go on a hot holiday, think shade, hydration and sun block.
Pigs subjected to high temperatures will have reduced growth rates (by up to 50g/day) and, in the breeding herd, farrowing rates could decline by as much as 25%.
Action for Productivity sheets 3 and 4 provide advice on keeping your pigs cool, whether they are inside or outside, including wallow management.
Action for Productivity sheet 39 provides more specific advice for heat stress in boars. Remember, boar fertility accounts for 50% of his progeny's genetics, but potentially 100% of output, as poor quality semen affects both conception and litter size.
