Buccalgesic is an oral (inside of cheek) pain relief for sheep and cattle that is now registered for use in Australia. It is easy to administer via an applicator similar to a drench gun and lasts for 2 to 3 days. Buccalgesic is suitable for pain relief as a result of procedures such as castration, tail docking and mulesing as well as general pain relief when treating lameness or other conditions. Obtain from your veterinarian.
