Equine Parasite Control Parasites and Pastures This presentation is from Virginia Tech and has not been edited by the Georgia Curriculum Office.
Enabling Objectives: • Identify different internal parasites common to horses • Identify different prevention methods for internal parasites in horses • Identify different types of dewormers available • Construct a sound deworming program for horses
Cestodes(tapeworms) Arthropods Bots Nematodes Common Internal Parasites
Cestodes • Long, ribbon-like, white • Commonly called tapeworms
Arthropods • Ticks, mites, etc. • Can live inside horse for part of its life cycle • Also bots
Bots • Flies deposit eggs on hairs on horse’s face, throat, legs, chest • Horse licks and digests larvae • Larvae travel through oral tissue to stomach and attach for 8-10 months • Pass out in feces, finish maturation in soil, emerge in spring
Nematodes: Large roundworms • Eggs ingested and hatches in small intestine • Migrate through bloodstream to liver and lungs • Large numbers found in foals • Heat will kill quicker than cold
Nematodes: Large Strongyles • Very harmful to horses • Larvae ingested and invade arterioles, travel through body to large intestine • Damage blood vessels-cause blood clots • Greatest infestation in spring and summer
Nematodes: Small Strongyles • Adults live in small intestine • Larvae enter lining of intestine and form nodules, they do not migrate any further • Can cause severe weight loss, diarrhea, colic and even death
Nematodes: Pinworms • Females move to rectum and deposit eggs around the anus • Eggs fall to the ground and are ingested and hatch in the intestine • Most common in young horses • Tail rubbing is a common symptom • Loss of body condition and appetite
Feed horses off ground Provide fresh water Clean stalls regularly Keep bedding to minimum in summer Regular deworming schedule Rotate pastures Rotate cattle and horses Tie stalls decrease number of worm infestation Internal Parasite Preventions
Deworming Program • Program usually aimed at adult, not larvae • Dose every 2 months • Spring and summer program important!
Types of Dewormers: • Ivermectin- Equimectrin • Benzimidatoles- Panacure • Pyrantel Panoate- Strongid P • Pyrantel Tartrate- Strongid C • Moxidectin- *Quest*- this is very specific to weight by distributing to body fat, can lead to death if overdosed- NOT FOR FOALS!!
Review… • Types of dewormers • Prevention measures • Importance of deworming program • Types of dewormers • Why is Quest so dangerous and why should it not be given to foals?
