Food Animal Drug Regulations

Exercise 6 Extrapolating withholding data

Particularly for minor use and minor species, you will not find a withholding time in FARAD for the particular species or route.
Google sometimes can be helpful. Other countries may consider the drug legal and have published withholding times. You can find some of these by using the search bar in FARAD:

This will result in some ads and in articles or publications that you might find useful (below the ads)

You can also search for similar species and/or routes. The closer you can get the better. Trying to extrapolate oral swine medications for subcutaneous use in an alpaca is unlikely to be close.
