Underdosing in Horse Worming: An Essential Warning
Posted by Ben Watson on 24th May 2023
In the realm of horse health, proficient worm control is absolutely vital. However, a frequently underappreciated issue in our horse-keeping community is underdosing. Although it might seem a minor concern, this mishap can prompt serious health repercussions like deteriorating physical conditions, colic, and in extreme cases, can be life-threatening.
Correct Weight Estimation: The Key to Effective Treatment
The problem of underdosing often springs from a simple but significant mistake – underestimating your horse's weight. This oversight is more widespread among horse owners than you might think, with a tendency to undervalue their horse's weight by around 20%. Considering that worming treatments are dosed based on weight, such inaccuracies can drastically impair the efficacy of the treatment.
It's critical to recognise that a horse's weight isn't fixed; it changes due to factors such as diet, exercise, and seasonal variations. Particularly during the warm summer months, these weight changes can be quite pronounced. Therefore, if you're basing your weight estimation only on height measurements or rough guesstimates, you're probably not getting an accurate figure.
The solution? Employ more reliable weight estimation methods. Weighing bridges, or horse scales, provide the most accurate measurements, but they might not always be accessible. In such cases, weight tapes can be highly effective. When working with centimetres and kilograms, a handy formula for mature horses is the product of Heart Girth squared and Body Length divided by 11,877, and for yearlings, it's the product of Heart Girth squared and Body Length divided by 10,036.
Navigating Wormer Administration and Worm Resistance
Another hurdle in worming arises when horses reject or spit out wormers. If this action is overlooked, it can drastically undermine the treatment's efficacy, leading to persistent parasitic infestations.
Furthermore, worms can develop resistance to wormers. This escalating problem intensifies the challenge of treating an infestation and presents a significant risk to your horse's health.
Responsible Wormer Handling: A Duty We Must Uphold
The implications of underdosing aren't limited to our horses – they reach their surrounding environment too. Discarded wormers or those spat out by horses can be accidentally consumed by other animals, potentially leading to poisonings. This can be especially dangerous for smaller pets like cats and dogs, thus, highlighting the utmost importance of safely and responsibly handling these medications.
Concluding Thoughts
Addressing the underdosing issue is crucial to maintaining the health of our horses and the safety of our farms. This involves accurate weight estimation (taking into account seasonal weight fluctuations), ensuring complete ingestion of wormers by our horses, and handling these medications responsibly. Additionally, strategic worm control measures, such as saliva tapeworm tests and faecal worm egg counts, are crucial elements of this strategy.
As horse caregivers, we bear a responsibility towards our horses and our environment. Remember, expert guidance is always close at hand – don't hesitate to consult your vet, or the knowledgeable pharmacists and SQPs at Hyperdrug. Their expertise is invaluable in managing these concerns. Ultimately, the health of our horses and the harmony of our farming communities is a shared responsibility that demands our commitment.
