The long cold spell has loosened rust and scale from inside water pipes on many pig units. It is therefore important to check all water drinkers are giving the correct flow for the class of stock as specified in the Welfare Code, says Paul Thompson, veterinary consultant to pig-breeding company ACMC Ltd.
He reminds producers to physically measure these flow rates on a regular basis. Periodic flushing and disinfection of the water system is also recommended, particularly where header tanks are used. These can accumulate surprising amounts of sludge and lead to bacterial contamination of the drinking water system, he points out.
