Novartis Animal Health recommend vigilance as changing weather could increase risk of nematodirus worms
Changing temperatures increase the risk of nematodirus worms, which require a period of cold weather followed by an increase of over 10 degrees to hatch. Nematodirus is especially dangerous to lambs, with a high mortality rate if measures are not taken to protect lambs whilst grazing.
Novartis advises direct action by using products such as the white drench Rybocen to control nematodirus and other roundworms.
