This Concept Map, created with IHMC CmapTools, has information related to: dehorning lab, nerve block consists of method, Any insecticides that are used as part of a fly control program must be labeled and registered for the intended use. In animal production facilities extreme caution should be exercised to be sure that only approved insecticides are used, and that label instructions and restrictions are followed. There are frequent changes in the insecticides approved and labeled for fly control by the different application methods and the latest information should be obtained. ???? Larviciding can also be accomplished by incorporating an insecticide into animal feed. Incorporating an insecticide into the water has been less satisfactory due to the irregular amounts of water consumption and difficulty in maintaining the proper dosage per animal. Although several chemicals have been experimentally effective for fly control in feces, most have not been registered for use. Often there are problems with residues in the animal tissues or products., nerve block consists of drugs used, type of block Cornual branch of the lacrimal nerve, Use of Gigli Wire Advantages 1. Fast cutting 2. Neat job done 3. Useful to remove horn scurs and to cut small horns before burning with hot iron, nerve block consists of type of block, Post Op complications Horn regrowth • Inadequate removal of the corium (horn-producing cells) will result in the regrowth of the horn, generally a partial growth that leads to scurs. Depending on the extent of the regrowth, the dehorning procedure may need to be repeated., Post Operative Care Topical Antibiotic Administration, mechanical 6-8 month old Technique 1. Close the handles together. 2. Place the jaws of the dehorner over the horn bud. The objective is to completely remove a ring of skin surrounding the horn base., mechanical button stage, Post Operative Care ???? Post Op complications, complications that can arise consists of improper usage of drugs, improper use of instruments consists of cutting to deep with Barnes dehorner. prolonged contact with dehorning iron. cutting improperly with gigli wire., Technique 1. Close the handles together. 2. Place the jaws of the dehorner over the horn bud. The objective is to completely remove a ring of skin surrounding the horn base. ???? Press the gouger gently against the head. Maintain the pressure and quickly spread the handles apart to remove the horn and skin. 4. Control bleeding by pulling the arteries with forceps or using a hot iron to cauterize the artery. 5. Clean and disinfect the jaws of the gouger between calves., DEHORNING IN CATTLE Intra operative considerations Preventative measures for possible complications, LINKS Gigli Wire Video, Post Op complications Flystrike • Dehorning method that leave an open wound should NOT but used during fly season. Paste and hot dehorning are acceptable anytime of year. • The use of a fly repellant may be warranted., Restrain the animal Hold ear out of the way Place the hot iron firmly against horn base Leave for 15 seconds Horns should have passed the button stage, nerve block consists of instruments, Post Op complications Pain • Animals should be monitored during and after the procedure for signs of unnecessary pain, such as vocalization, reluctance to move, and failure to nurse. Such animals should be treated with a systemic analgesic such as flunixin meglumine.
