Timo Heikkilä’s farm with 3,500 sows, 6,000 piglets (between 7 and 30 kilograms) on the flat deck and 1,200 gilts (between 30 and 140 kilograms) is located in Rusko in the south-west of Finland, 200 kilometers west of Helsinki. “Here in Finland, docking tails has been banned since 11 November 2002. Still, we started keeping long-tailed pigs in January 2003,” Heikkilä reported. And his results are proof that his approach is right: merely two percent of animals arrive at the slaughterhouse with damaged tails.
“The main cause of tail-biting is stress,” emphasized Heikkilä. According to him, stress is caused by a number of factors: for instance, preventing animals from feeding at the same time. Also, the environmental control is often not adjusted properly, leading to poor ventilation or draft. “Another factor is a lack of material for activity or playing,” he added. “Simply by eliminating these stress factors, much can be achieved,” Heikkilä confirmed.
Heikkilä therefore encourages pig farmers intending to switch to keeping long-tailed pigs, advising: “To reduce stress for animals, I recommend installing long troughs, meaning a 1:1 feeding place ratio. Also, animals are best supplied with a liquid feeding system.” Timo Heikkilä has been working successfully with WEDA liquid feeding for years. “This ensures my animals receive high-barley feed. I’m rather skeptical towards wheat, since it contains less crude fiber,” he reported.
Hygiene systems are essential
Timo Heikkilä exclusively feeds pelletized purchased compound feed. Pelletization prevents contamination of his animal stock with salmonella via the feed. Also, he uses acids for feeding. Not least, Heikkilä considers solid hygiene to be essential for liquid feeding: “Our system is equipped with the latest WEDA hygiene technology. It includes regular cleaning of tanks with UV light, rinsing the entire system with lye and cleaning the outlet pipes in the house.” This way, Heikkilä does not give germs and bacteria any chance to develop.
A favorable house climate Another pillar of his concept is a favorable house climate. To achieve this, harmful gas pollution must be reduced. In Rusko, this is managed in three ways: by lowering ammonia levels, by channeling supply air directly to the pens and through a sealed-floor portion of two thirds. Especially the latter keeps down manure surfaces in the compartments.
