Parasite Control
About Parasite Control
SEFARI responsive opportunity fund project: Creating interactive information for farmers.
There is lots of information available on the sustainable and effective control of roundworms from a wide range of sources. We have pulled together a directory of useful links providing information on the topics listed below.
Using anthelmintics correctly prevents underdosing, a key factor in the development of anthelmintic resistance.
Table of links to information and guides on effective anthelmintic administration:

One of the key methods of protecting the efficacy of anthelmintics on farm is to avoid importing resistance by employing effective quarantine to all new and returning stock.

Refugia describes the worm population on farm which is unexposed to treatment – e.g. worms on pasture and those residing in untreated animals. It is important to maintain a diverse refugia of worms on farm as these will dilute any resistant worms which survive anthelmintic treatment, slowing down the development of resistance on farm.

Working out when to give anthelmintics can be difficult. Including targeted selective treatments (TST), targeted treatment (TT), the strategic use of long-acting products and using the new drug classes to perform ‘break doses’.

With the advancement of anthelmintic resistance in the UK and worldwide, alternative roundworm control strategies can be integrated into farm management practices to reduce reliance on anthelmintics. Alternative strategies include grazing management, selective breeding of sheep/cattle for parasite resilience and forages which provide anthelmintic properties.
