Summer HorsesRoutine worm count time

Regular worm egg counts should form the base of your programme at this time of year. For healthy adult horses that means sending in a faecal sample to be tested at three monthly intervals. For youngsters, rescued horses or those with a history of high counts, shorten the gap to six to eight weeks as they are so much more susceptible to infection.

These intervals are based on the life cycle of the small redworm which can complete in as little as five to six weeks, meaning a parasite infection can very quickly get out of hand. Testing regularly helps to prevent a parasite problem getting out of hand.

No horses should be blindly treated without testing first; our worming drugs are far too precious to be wasted in this way and will not stay effective for the future if used in such an irresponsible way.

Is it tapeworm time?

Tapeworm eggs regularly appear in samples under the microscope in summer and are reported where they do. However a sample clear of eggs does not necessarily mean a horse is clear of tapeworm so build the Equisal saliva test into your programme for certainty.

We are often misled into thinking only of spring and autumn being ‘tapeworm time’. This traditional pattern was a convenient way to include tapeworm doses in those old fashioned rotational drug programmes but there is no other advantage to sticking to this.  If you are one of the many who worm with Equest Pramox in the winter months to cover encysted redworm and tapeworm, the summer is an ideal interval to use the Equisal test to check for tapeworm.

Tapeworm eggs are carried by the forage mite, active on grassland all summer and ingested by the horse while grazing. It takes approximately five to six months for the tapeworm to complete its lifecycle. As it is now about six months since that winter dose, it’s a good time to test.

Roundworm reminder.

We should be thankful for modern worming products which give us a safety net for treating those horses found to have significant parasite burdens but be wary of forgetting some of the older drugs which still have their uses. There seems to be an emerging problem with roundworm (ascarid) burdens in adult horses around the ages of six or seven. These animals have only ever been wormed with modern ‘mectin’ wormers, not always the drugs of choice for treating roundworm as there is rising ascarid resistance to these drugs. To prevent this it would be wise to make sure that all youngsters are given a specific dose of either pyrantel or fenbendazole in their first year, targeting ascarids. Once dealt with this problem is unlikely to reoccur as ascarids are rarely seen in older animals.

Bot flies.

With summer flies comes the potential for bots which lay their yellow, torpedo shaped eggs on the horse’s legs and shoulders. Try to remove these with a bot knife if you can. Your horse will find them irritating and in licking will start the next stage of the lifecycle. They can cause sores at the back of the mouth as they take up residence between the teeth here prior to passing into the horse’s stomach to over winter. Once there it is thought that they cause few problems unless present in large numbers. A dose of ivermectin or moxidectin late in the year after the first frost should treat them but prevention is better than cure.

Ticks off!

Our changing climate and other environmental factors are influencing an increase in the numbers of ticks which we are seeing coming in on our horses, dogs, cats and even ourselves with alarming regularity. These tiny blood sucking parasites live in grassland and latch into the skin of their host to feed. Tick bites can cause localised skin irritations, anemia from blood loss in larger numbers and also have the ability to transmit serious diseases such as Lymes Disease. 

Swift removal is important to reduce the risk of pathology and ensuring they are taken off in one piece without leaving the mouthpiece embedded in the skin will also help to prevent infection developing in the wound.
