Worming the young horse

In the first video we discussed how to deworm adult horses and how to use the gold standard Virbac wheel to pick the right product for the right time of year. In this video we’re gonna discuss the differences between adult horses and our younger horses, weanlings and foals and how they need to be dewormed differently. The difference between adult horses and foals and weanlings is that our younger horses are susceptible to ascarids or roundworms. These worms live in the small intestine and can cause disease such as poor weight gain and ill thrift, and in large enough numbers can cause oftentimes fatal episodes of colic. As horses age they develop a natural immunity to ascarids so we only worry about these parasites in our younger animals. Another consideration is the state of roundworms in Australia. We are seeing widespread resistance to our common dewormers meaning that the worms that we see on our farms are not being killed by our traditional dewormers. When you look at the gold standard wheel you’ll notice that younger horses have their own section in the center where we recommend Strategy-T and Equimax Elevation. These combination products contain pyrantel and are effective against resistant roundworms. We use the same seasonal strategy as we do in adult horses, recommending Strategy-T for our younger foals in the spring and summer and Equimax Elevation for our older foals and weanlings in the autumn and winter. These young horses should be dewormed beginning at eight to twelve weeks of age and treated regularly until they’re two years old, at which point they can move to the outer edge of the circle and be treated with the Strategy-T and Equimax section.
