Cooling down for more hygiene, less ammonia

Keeping pigs cool in times of heat stress has a positive effect on their fouling behaviour and subsequently on the formation of ammonia. In Sweden, researchers tested 2 methods of cooling finisher pig houses with partly slatted floors and measured the effect on fouling behaviour. Partly slatted pens have a solid floor for pigs to lie on and a permeable slatted floor as a dunging area for the pigs. This design enables allocation of some litter as enrichment. Use of litter reduces problems with t
