sheep: the autumn double challenge

In autumn there is likely to be a mixed burden of both stomach worms and fluke on most farms in the UK. The milder winters and wetter summers are working to increase this risk. Worm and fluke infestations individually cause production losses, a combination of both can be exponentially worse. Worms can result in a loss of up to 4.7kg live-weight and fluke can cost up to £3-5 a head1,2 .Results from the Parasite Watch farms and VIDA data suggests that mixed infestations are common:

  • Active against all liver fluke stages


The transition into housing is a risky time for first grazing season animals, there are so many things to consider; dietary change, weaning, grouping, respiratory disease, and how to control parasites, specifically fluke and worms.

Protecting cattle against fluke at housing rather than delaying treatment will yield a financial return by reducing stress and improving growth rates, according to a recent study3.

A trial by FAI Farms in Oxfordshire compared the effectiveness of parasite treatments in first season grazing animals. The treatments were either; the fluke and worm pour-on CYDECTIN® TriclaMox® or the worm pour-on CYDECTIN® given at housing, a group was also given no treatment to determine the impact of delaying treatment.

The stress of housing and weaning led to an 89% drop in growth rates across all groups. Cattle handled post housing also have the potential for a second growth rate dip of 20% as a result of being handled twice.

Don’t delay

Cattle treated at housing with CYDECTIN® TriclaMox® outgrew those that were untreated during the 4-8 weeks post housing. It is at this time after housing that many farms would consider treating their cattle, missing out on vital growth rate and profit during the 4-8 weeks post-housing;

  • Animals treated at housing with CYDECTIN® TriclaMox® gained an average of 16.1kg
  • Cattle treated at housing using with CYDECTIN® gained 13.4kg
  • Cattle offered no worm or fluke treatment at housing gained 8.6kg.
weight difference

Therefore, treating cattle for worms and fluke at housing has been shown to produce both production and management benefits; from an animal management point of view, it reduces the need for further handling of animals later in the housing period. From a productivity perspective, animals that were treated at housing had the potential to finish up to 12 days before untreated animals and also gained up to 7.5kg more delivering an extra £16.52 per head.

CYDECTIN® TriclaMox® is the only combination fluke and worm product to provide both a persistent wormer and triclabendazole - no other Pour-on or injection is more effective against adult and immature fluke. Treating cattle at housing rather than delaying treatment has been found to improve growth rates compared to animals receiving delayed treatment or no treatment at all.
