[Economical consequences of intestinal nematodes infection in pigs]

The studies wers carried out in ZZD Kolbacz on 14 sows. The experimental groups control and treated consisted of 7 sows each. The sows were treated with Dectomax - 1 ml/33 kg of body weight. The efficacy of sows treatment's was verified with the Wllis-Schlaaf and McMaster method. The studies indicate, that subclinical infection of intestinal nematodes could influence the swine production. The piglets from treated with Dectomax sows were infected in 8% only; when all piglets from non treated sows were infected with nematodes. From treated sows 0.8 more piglet were obtained and the weight gain of litter was after 6 weeks 24.4 kg higher comparing with the control group.
