How Does Worm Infestation Affect Horses?

There are various ways horses get affected by worm infestation. This is regardless of the fact that worms are not known to cause horses major issues.

If a horse plays host to worms and nothing gets done about the situation, it could become a major challenge. This is most prevalent in debilitated horses, pregnant mares, yearlings, and foals.

Generally, there are some signs you should look out for to tell if your horse is infected by parasites. Some of these signs are colic, bad hair coat, pneumonia, etc. While you can always assume that your horse is infected with worms because of certain signs, you might be wrong sometimes.

How do Horses Acquire Worms?

This has remained a mystery to some people. If you have always wondered how your horse keeps housing worms, you will get an answer today.

Generally, spending time in a contaminated pasture or with horses that have been infected in the past can make horses infected with worms.

All things being equal, a pasture can get infected when it houses the larvae or eggs of parasitic worms.
