An increasing number of dairy producers are converting from hot-iron to caustic paste for early age dehorning. Here’s why:
1. Paste is less painful: Research from the University of British Columbia found that calves dehorned with caustic paste experience less pain than calves dehorned with a hot iron, even when a local anesthetic is used.
2. Paste is safer for crew: You may remember this guest blog by Jeanne Wormuth, manager at CY Heifer Farm, citing an employee’s burn injury as the main reason her facility switched to paste. There’s also no need for a squeeze chute or extreme physical restraint. Check out this video of a calf being dehorned with caustic paste.
3. Paste has high acceptance in the industry: Caustic paste is consistent with recommendations from the Dairy Calf and Heifer Association (DCHA) Gold Standards III, which recommends a “cautery” method at less than one month of age, and the AVMA Animal Welfare Policy, which recommends that dehorning be performed “at the earliest age practicable.”
4. Paste is preferred by consumers: With paste, there’s no smoke, no bawling and very little, if any, resistance from the calf. And there’s nothing sensational to capture in an undercover video.
