ARM urges pig farmers to check ventilation systems as back up builds

AS overweight pigs continue to back up on many pig farms, environmental specialist ARM Buildings Limited has made an urgent plea to pig farmers to check the ventilation systems in their finishing houses.

“Larger pigs produce much more heat so fans will be working harder to keep piggery temperatures down, even as cooler autumn weather approaches,” said Tim Miller of ARM Buildings

He said that the build up of meal dust and other debris on fan motors and blades can seriously reduce their efficiency, and so need to be thoroughly cleaned, and the mechanisms on air inlets should be checked for sticking as well as ensuring the alarm and whole emergency ventilation systems are working properly.

“A house of 1,000 pigs at the end of their finishing period can produce 170 kW of heat – enough to heat 8-10 average-sized homes,” he pointed out. “That’s a massive amount of heat to be dispersed.”

He added that finishing houses housing pigs as heavy as 145kg liveweight are also putting a strain on the buildings, particularly on older structures.

“It is ironic that pig farmers are being constantly lectured on animal welfare and having to consider expensive changes to freedom-style farrowing systems while a build-up of pigs, through no fault of their own, could cause major welfare problems. The government and supermarkets do not seem to comprehend the seriousness of the situation – and the threat to future British supplies of pork,” he added
