The Parasight
Welcome to this month's edition of The Parasight. We’re taking parasite-threat updates to the next level with our collaboration with post-mortem vet Ben Strugnell BVM&S Cert PM MRCVS from Farm Post Mortems, who will share with us timely, on-the-ground footage.
Understanding what’s actually happening in flocks around the UK will give you more insights on what you should be looking out for with your own animals.
Cattle health: worm control watch outs - June 2025
Description: this month, Ben discusses two cases highlighting the importance of timely diagnostics and worm control in cattle.
In the first case, a group of spring-born calves were found to have a low worm burden following a composite worm egg count test. However, by mid-March, three calves began to lose condition. All were treated with a wormer, but one died shortly after. Post-mortem findings revealed type 2 ostertagiasis. This is followed by a discussion on the watch outs of worm egg count tests and other diagnostic options available.
Ben also covers a case involving bought-in heifers, which were wormed one month after housing. One died ten days after calving. A post-mortem revealed adult lungworms, raising concerns about potential anthelmintic resistance.
