This autumn it’s important to assess the exposure that cattle may have had to worms during the grazing season, says Timothy. Measures can then be taken to ensure heavy worm burdens are removed before housing that would otherwise continue to impact on their performance over the winter.

However, it’s important that parasite control is sustainable as well as effective. Timothy explains the threat posed by unsustainable worming practices, in terms of the development of anthelmintic resistance, which could render wormers ineffective in the future. To avoid such a situation, dairy producers should seek to understand the principles of sustainable parasite control and, in conjunction with their vet or animal health advisor, develop strategies to implement on farm.

“Adopting an integrated parasite control plan which utilises pasture management and parasite risk assessment, alongside reduced reliance on wormers and better targeted treatments, will help to preserve the effectiveness of wormers for the long term,” says Timothy.

Top tips for sustainable parasite control include using grazing management to reduce the exposure to parasites, particularly for young, more susceptible cattle, and using risk assessment tools to determine which animals are most at risk, and guide targeted treatment strategies.

You can read more tips and advice on worming at housing in The Parasite Papers, in the October issue of British Dairying. Always ask for advice on anthelmintics from your vet or animal health advisor.
