Worm-Infestation in Sheep

Abstract
Grazing management is of paramount importance in the control of nematode worms in sheep at pasture. Experiments show that, starting with a clean sward, it is possible by rapid folding to prevent re-infection altogether and keep infestation so low that little or no damage occurs. Worm-free lambs can also be raised in this way. But difficulties arise in practice, and both management and anthelmintic treatments will normally be required.
