In conclusion, all application times used in this study resulted in some level of brain injury however, using 15 s or more resulted in more severe and consistent brain injury. Microscopic lesions consisting of leptomeningeal and cerebrocortical necrosis were observed in sections of brain from all groups. Gross evidence of discoloration and hemorrhage on the cerebral hemispheres was observed on two horn buds that received 20 s, two horn buds that received 15 s, and one horn bud that received 10 s. No bone abnormalities were identified on any kids. With the exception of the horn bud that received 5 s, which had white matter edema restricted to a single gyrus, the remaining three groups had a branching region of edema. From the MR images, white matter edema was observed subjacent to four treated areas, representing application times of 5 s (one horn bud), 15 s (one horn bud), and 20 s (two horn buds). Additionally, four of the six kids were presented for gross examination and two kids were selected for histopathologic examination. After a 5-day observation period, the kids were euthanized, and magnetic resonance (MR) images were acquired to evaluate brain injury. Kids were disbudded using an electric cautery iron (under isoflurane general anesthesia). Kids received a different randomly assigned application time (5, 10, 15, or 20s) on each horn bud. A total of six buck and doe kids <9 days of age were obtained from a commercial dairy and transported to an Iowa State University research facility. Therefore, the objective of this pilot study was to evaluate the effect of iron application time on brain injury of goat kids. Cautery iron application time may affect transmission of heat to the brain however, research in this area is scarce. Thermal damage to the cerebral cortex of the brain and subsequent neurologic disease is a primary concern. 6Veterinary Pathology, College of Veterinary Medicine, Iowa State University, Ames, IA, United StatesĬautery disbudding is a painful procedure performed on goat kids to prevent horn growth that may result in brain injury.5Biomedical Sciences, College of Veterinary Medicine, Iowa State University, Ames, IA, United States.4Idexx Laboratories, Westbrook, ME, United States. 3Veterinary Clinical Sciences, College of Veterinary Medicine, Iowa State University, Ames, IA, United States.2Animal Behaviour and Welfare, AgResearch Ltd., Ruakura Research Centre, Hamilton, New Zealand.1Veterinary Diagnostic and Production Animal Medicine, College of Veterinary Medicine, Iowa State University, Ames, IA, United States.
