Ecological pig producers in particular, who often don't use conventional anti worm treatment, may benefit of using the herbs.

Trials showed that a mixture of thyme, lemon balm and purple coneflower at a 5% inclusion rate in the feed of pigs resulted in a good prevention against the round worms. However, a dosage of 5% is economically not feasible. ASG therefore investigates whether the dosage can be lowered and if the addition of black tea may improve the efficacy of the herb mixture. Black tea is rich in tannins, which is assumed to limit the amount of worm eggs produced. The tea also disrupts the ability of worms to attach to the intestinal mucosa layer.

Fattening pigs

ASG is currently running trials with individual housed fattening pigs that have been challenged with a worm infection. Some animals receive the herb mixture with 1% thyme, lemon balm and purple coneflower in the feed. Some animals receive the same mixture, added with 1% black tea. Both groups will be compared with control animals and animals that received Flubendazole at day 42 after infection. eep it natural
