Questions

Immunity can be either innate or acquired, do you know the difference between the two?

Immunity is the means by which sheep become resistant to worm infection. The immune response by sheep is complex and requires exposure to a sufficient level of infective worm larvae.

 

Innate immunity is displayed in the first exposure of sheep to infective worm larvae and does not typically play a large role in resistance to worms.

Do you know where to find the Meat Withholding Period (MHP)?

The meat WHP appears on the labels of all registered veterinary products.

 

Withholding periods are mandatory with all registered veterinary products used to treat sheep for worms, flies or lice. These periods have been developed to indicate when the chemical residue that remains in or on meat and wool products will not exceed the maximum residue limit.
