Immobilizing European Wild Hogs With Cap-Chur-Gem

Cap-Chur-Gem was injected intramuscularly into 22 pen-reared and six wild trapped European wild hogs. In pen-reared hogs, complete immobilization occurred in 13 hogs (68 percent) at dosages of 1 cc./9.9 to 1 cc./18.6 pounds of body weight and incomplete immobilization occurred in six hogs within the same dosage range. The remaining three penreared hogs showed little or no effects when injected with dosages smaller than 1 cc./19.0 pounds. Three of the wild trapped hogs were immobilized at dosages of 1 cc./10 pounds and three were not immobilized at dosages of 1 cc. per 14 to 20 pounds. The tIme from injection to immobilization varied from 6 to 62 minutes and averaged 25.3 ± 8.4 minutes for penreared hogs. Time from injection to immobilization and recovery for wild trapped hogs averaged 27.7 and 79.0 minutes and varied from 2 to 69 and from 51 to 135, respectively. The recommended dosage is 1 cc./15 pounds body weight. Cap-ChurGem is an effective drug for immobilizing European wild hogs, but it possesses no advantages over Cap-Chur-Barb. Cap-Chur-Gem was found to be an effective drug for immobilizing European wild hogs (Sus scrofa). Effective immobilizing drugs are useful in handling hogs because they reduce chances of injury to the hogs and handling personnel and allow research procedures to be conducted more easily and effectively. It was intended that immobilization would facilitate the following procedures: tagging (Matschke, 1962) and ear notching (Winters, 1952) for identification, examining for external parasites and dental pattern (Matschke, 1967), measuring for growth studies, and blood sampling for chromosome counts (Rary, et. al., 1968), hematologic determinations, and recording of blood parasitism. The purpose of this study was to evaluate one immobilizing agent, Cap-Chur-Gem, for use on European wild hogs. Evaluation of Cap-Chur-Barb (Henry and Matschke, 1968) was reported earlier. We wish to thank James C. Lewis, Research Supervisor, and Dr. B. H. Erickson, Associate Professor, UT-AEC Agricultural Research Laboratory, Oak Ridge, Tennessee for reviewing the manuscript and offering suggestions. Drs. Frank A. Hayes and Theodore R. Ridgeway of the Southeastern Cooperative Wildlife Diseases Study assisted in perfecting the procedures used with Cap-Chur-Gem. L. A. Hunt and D. J. Williams also assisted in the study.
