[QUOTE="Taurus, post: 943151, member: 18288"] Horns and the skull are composed of boney tissue with blood and nerve supplies. Dehorning is actually surgically amputating or fracturing the bone. Surely that wouldn't hurt, cause stress, or bleed. [url=http://www.dehorning.com/faqs/]http://www.dehorning.com/faqs/[/url] Q. Is dehorning painful? A. Yes. The corneal nerve, running from behind the eye to the base of the horn, supplies sensation to the horn. Studies have shown that dehorning stimulates both an acute pain response and a delayed inflammatory reaction.2 According to Dr. Todd Duffield, a researcher at Ontario Veterinary College at the University of Guelph, “With the possible exception of caustic paste, calves perceive and react to acute pain during dehorning, regardless of method, when no local anesthetic is used.” 2 The American Veterinary Medical Association recognizes that dehorning causes pain, and recommends the use of procedures and practices, including approved medications, to eliminate or mitigate discomfort.1 [url=http://www.ncbi.nlm.nih.gov/pubmed/18085156]http://www.ncbi.nlm.nih.gov/pubmed/18085156[/url] There were significant differences between the SLA and LA groups in peak plasma cortisol levels (p = 0.011) and in occurrence of stress behaviours (p = 0.003). Sedation induced by intramuscular administration of xylazine in conjunction with local anaesthesia with lidocaine is considered the most suitable method of anaesthesia when dehorning adult cattle. Local anaesthesia with lidocaine alone was least suitable. So what type anaesthesia did you used to dehorning your cattle? [/QUOTE]
