Controlling Parasites
For optimal flock health and performance
There is no single “proper” protocol that will apply to every farm.
A deworming schedule needs to be tailored to the individual farm based on a number of risk factors including but not limited to:
• Stocking density
• Annual rainfall
• Location in degrees latitude
• History of dewormer use on the farm
• Pasture rotation
• Local climate
• Genetics of the animals
All of these factors increase or decrease the susceptibility of the animal to parasites and increase or decrease the larvae survival on pasture.

The
To keep the parasite numbers low enough so they do not threaten the health or performance of the sheep or goats. It shouldn’t be to keep livestock parasite-free. This is unrealistic and will result in overuse of dewormers.
GOAL
62
Depending on where you live and pasture conditions, you may
need to deworm 2 to 6 times a year. Rotation among the three classes of dewormers is recommended (avermectins, benzamidazoles and levamisole). We strongly suggest that you submit a fecal test to determine which worms your flock is fighting in order to select the best dewormer for them.
One of your deworming treatments should occur at lambing/kidding or shortly before as there is a rise in worm activity as ewes/does approach lambing/kidding.
Young stock (less then 6 months of age) need to be dewormed more often than adults as their bodies are focused on growth and not necessarily fighting off parasites. Sheep or goats in a dry lot (no green growing forage) typically do not acquire parasites and may never need to be dewormed.
An alternative method...
Livamol® with BioWorma® and BioWorma® (p. 61) has been used successfully to eliminate larvae from pastures in Europe and Australia, but is new to the USA. It does not eliminate parasites present in the animal. For optimal performance, animals need to be first treated with a dewormer/anthelmintic (p. 60) to lower worm load before feeding BioWorma products.
