Learn to Manage Parasite Resistance on Your Farm
Equine gastrointestinal parasites, and their increasing resistance to available de-wormers, are a major concern in the equine industry. Taking a whole-farm approach to managing parasites can decrease the frequency of deworming, eliminate the use of products that are no longer effective on your farm, help you learn which horses have natural resistance and which ones are “shedders,” and help decrease the development of resistance to de-wormers. Routinely deworming with the same products, or simply rotating de-wormers, is not the best method and can contribute to the development of parasites that are resistant to the products that we use. Since no new products are on the immediate horizon, if resistance continues to progress at the present rate, the equine industry may face a major crisis.
Indiscriminate use of dewormers has caused an alarming increase in resistant equine parasites. Cases of resistant small strongyle parasites are being reported worldwide. In 2015 and 2016, owners and managers of 74 PA horse farms, representing 711 horses on farms in 23 Pennsylvania counties enrolled as partners in a Penn State research project designed to document parasite levels in horses and determine which products are still effective. This program will discuss new strategies to manage parasites and reduce the use of dewormers and will share the results of the project with you!
To Be Covered
- Types of parasites
- Resistance and the importance of establishing a refuge of non-resistant parasites
- Classes of de-wormers
- Conducting fecal egg count on your farm
- New strategies to manage parasites
- Results of our 2015 & 2016 parasite project
Our goal is not to eliminate parasites but to utilize a comprehensive approach to reduce transmission, maintain parasites below harmful levels, and manage horses that maintain chronically high parasite levels. Utilizing a whole farm approach incorporates maintaining high quality pastures to reduce grazing near manure areas and adopting good manure handling practices.
Participants of this workshop will learn to conduct fecal egg counts and learn how this will help determine the effectiveness of the products you are using. Join us for this exciting opportunity to help yourself, your farm, and your horse.
Workshop Note - Horse Fecal Samples
Participants are welcome to bring along one or two fecal samples from horses on their farms to practice conducting fecal egg counts.
Be sure to follow these directions to collect fecal samples.
- Collect 3-4 fecal balls from the floor of a clean stall.
- It is very important that the samples are as fresh as possible
- Collect a sample from each individual horse in a plastic bag and seal all of the air out. 4. Label each
- bag with the horse's name.
- Avoid exposing sample to temperatures above 100 degrees Fahrenheit at any time.
- Do not let sample freeze.
- Refrigerate or put sample in cooler with ice packs immediately.
- Sample needs to be "normal" manure. Diarrhea will not give accurate results.
Please do not bring more than two samples we will not have enough time to do more.
