the 14 farms
3 farms went from burning to paste
3 farms increased paste use
3 farms continued burning but burned at an
earlier age
5 farms did not change methods

2 farms already using paste
 Two
farms increased use in lidocaine and
meloxicam
 One farm increased use in polled genetics
 Calves
don’t fight as much when given
lidocaine
 The paste is a lot easier than I thought
 Burn the horns when they are smaller
 Polled bulls don’t have high enough type
numbers
 Dehorn
calves at an earlier age
 Work with your veterinarian on a dehorning
protocol
 Use pain management on older calves
 Introduce polled genetics to the herd
