The purpose of GUIDELINE 78 Biosecurity for Sheep and Goat Dairies is to provide producers with a practical guideline for implementing biosecurity practices on sheep and goat dairies that will increase profitability and prevent unnecessary outbreaks of disease. Maintaining sound biosecurity is important as the introduction of disease into a herd/flock can be costly in terms of increased labor, decreased production, increased veterinary expenditures, and premature culling.
