I bought a packet of "Vičinec vikolistý" in the garden store the other day. It is the variety called "Taja". I was told people grow it for pigs, but now I've looked it up and found that it is a legume that has anti-helmitic properties. Just thought I'd mention that, since people have posted it in lists of sepp holzer's pasture seed mix. So including it in your pasture should help with any worm problems in ones animals!
