Horse Worming – save money and your horse with less

Last year we started a new worming protocol at Halcyon Acres. In fact, the subject was a blog topic here and included a promise to report back on our findings.  Here they are:

Opting for fecals over standardized worming practices

Basically, we decided to stop systematic worming in deference to a plan that is safer for the horses – both now and into the future. Research is increasingly sounding the alarm about parasite resistance to equine products. Studies have shown horses can be kept healthier and infestations better controlled with customized approaches based on manure examination. The recommended approach is to take fecals twice annually – in the spring and after a good couple of killing frosts in the fall (horses with issues may need to be checked more frequently until they are resolved). The findings determine customized future worming regimens for each horse. The results, including cost savings, were surprising.

Because we tend to get a lot of traffic through the farm with client horses coming in for short-term training, we were pretty aggressive about worming – covering the entire equine resident count monthly with a rotational approach. These wormers ranged from $4 – $15/ horse, per treatment. We stopped all worming about mid-year in 2009 and took stool samples of the twelve horses that were here in April. Three had high counts. All, but one were a surprise. Those we would have expected to be vulnerable came back clean.

The three with high counts were wormed twice, eight weeks apart (in April and June). Given the findings, we were able to use an inexpensive wormer ($4) that addressed the present parasites. There were a number of horses at the farm that were mid-range, and wormed once. All nursing mares will be wormed once after the foals drop, now and in the future. Four of the twelve had such low counts they did not require any treatment.

Surprising findings with the herd

One of the strange revelations in all this was that the healthiest looking horses with the least stress on their systems accounted for two of the three high count critters. The low count horses included our maiden broodmare who suffered a terrible time recovering from injuries, weight loss and despondency after coming home from a live breed fiasco; a two-year-old who’s spent much of his life on antibiotics as an accident magnet; a ship-in client horse that travelled cross country with some existing health concerns; and a mare in training who acts out aggressively with the herd due to some clear confidence issues. The three high counts were all turned out in different areas. Ditto for three of the low counts.

Are you wasting money on your worming program?

While the number of horses are never the same here with the influx and departure of client horses coming in for training, since there were twelve for the April fecals, this serves as an easy figure to work with in determining costs. Each fecal was $25 (this can be done much more cost effectively and with more refined conclusions if you’re willing to do your own collection, labelling and shipping out of state – we’ll probably do this next year). So the total cost this spring (we didn’t do fecals in the fall) was $300 for the service of putting manure under a microscope. We’ve determined our average worming cost per month, per horse is $10. That’s $120 per month to worm twelve, or $1440 a year. Because we had test results in hand, we were able to use a $4 wormer to address the concerns (instead of a $10 or $15 product). We wormed nine once (including a nursing broodmare who did not register a parasite count of concern, but worming was advised to transfer through to the foal’s milk) and three twice, for a worming cost this year through fall of $48. So, assuming costs and results are the same in the fall (it’s likely they will be reduced now that we’re on a knowledge-based treatment plan), that’s $696 for the year, a $744 savings (or more than 50%). Plus, we’re increasing the likelihood of healthy horses, doing our part to reduce future parasite resistance to wormers and probably helping the environment in more ways than we realize.

Take better care of your horse

So, if you’re on the fence about springing for the cost of fecals on your horse, or your herd, think again. It’s likely you’ll save a good deal over the course of the year in funds, stress and potential horse health issues that may arise from unknown parasite residents. We didn’t embrace this new approach blindly or spontaneously. These studies have been going on for years. You should be alarmed at the prospect of parasites in your horse that cannot be controlled. We now have our own success story to add the mix, at least at an anecdotal level on a smarter, safer and visionary approach to horse health maintenance.

Is keeping the horse you love a struggle?

Horses aren’t just recreational vehicles to be sold off as commodities when times are tough. They’re pets and partners representing ‘me time,’ emotional bonds, spiritual enrichment, psychological stabilizers and confidants. Before you decide you can’t afford a horse anymore, consider the real costs – and try to get creative about how you may be able to hold on.
