When It Comes To Dehorning, Pain Relief Pays.
Dehorning is a painful, stressful procedure. Although the American Veterinary Medical Association recommends the use of pain relief for procedures like dehorning, a survey of U.S. dairy farms found only 12 percent of producers used a local anesthetic (nerve block) on dehorned calves, and only two percent used analgesia (like nonsteroidal anti-inflammatory drugs or NSAIDs). A similar survey of Ontario dairy farms found only 23 percent of producers use lidocaine nerve blocks at the time of dehorning.
Those numbers might improve if producers were aware of the economic benefits associated with the use of pain relief and stress reduction. For example:
Reduced disease. All producers know that pain and stress increase an animal’s susceptibility to disease. An article published in the Journal of Animal Science in 2011 showed that calves treated with NSAIDs prior to castration experienced less bovine respiratory disease (BRD) in the feedlot. BRD steals dairy profits through treatment costs, reduced milk production and death loss; the impact is even greater on the beef side, where the disease costs an estimated $800 and $900 million a year. Producers can help reduce these losses by using pain relief for invasive procedures like dehorning.
Higher performance. Dr. Temple Grandin has written extensively on the impact of stress and fear on animal performance and meat quality. She has cited numerous studies showing that stressed animals experience significantly lower weight gains, reduced reproductive function including abortion, lower rumen function and lower milk yields. Conversely, reducing stress “will help reduce sickness and enable cattle to go back on feed more quickly,” she wrote. The Journal of Animal Science article showed that pain relief used in calves at castration can increase average daily gain.
So why aren’t more producers using pain management for dehorning? Cost is a factor, of course. So is lack of certainty over effectiveness, especially for paste disbudding which is minimally invasive to begin with. Then there’s the issue of training and anatomical knowledge, which may be necessary for determining dose, route, duration and frequency of drug administration.
As the food animal system moves toward greater transparency, consumers increasingly want assurances that their food is produced in a safe and humane manner. Not only is pain relief good for the calf, and reassuring for the consumer, but it may actually be profitable as well.
