Extract Sir, — As from October 1976, all sheep in this country will have to be stunned prior to slaughter. Until recently it had been widely assumed that some form of electrical stunning would be the only practical method for use in New Zealand freezing works. Although for several years electrical stunning has been used for pigs in this country and other classes of stock overseas, only one meat export works in New Zealand has been stunning sheep electrically as a routine procedure for a complete season. 相似文献

Extract Sir,—The surgery tables at present commercially available in New Zealand are fixed in one position, though some may have their height altered by a hydraulic pump or other means. It is considered that the following conditions should be met by a surgery table. 相似文献

The instrumentation and technique for reimplantation of the left lung of 6 dogs was described in detail. Thoracic radiographs made during the first 3 postoperative days consistently showed scattered areas of consolidation in the 3 left lung lobes characteristic of alveolar and interstitial infiltrates. Following a peak reaction at 3–5 days postoperatively, the infiltrates gradually resolved at a variable rate and disappeared completely within 2 weeks. All dogs were euthanized 14 days after operation and postmortem examinations were performed. No stenosis was noted in the bronchial, arterial, and atrial anastomoses. Histopathologic examination by light microscopy of lung tissue indicated no abnormalities. Arterial blood gases and pH, and mean pulmonary artery and pulmonary wedge pressures determined immediately prior to euthanasia were within normal limits. 相似文献

Current reports advise against attempting simultaneous bilateral mastectomy in the dog. However, total mastectomy may be the most logical treatment for all dogs with mammary tumors in view of newer evidence suggesting a multicentric origin for this disease. A surgical technique for simultaneous bilateral mastectomy was evaluated in 22 dogs with mammary tumors. The procedure was successfully performed in selected patients and healing occurred without serious complications. The technique, rationale, and recommendations for use of this procedure are presented. 相似文献

A prosthesis designed to partially replace the articular surfaces of the radial and third carpal bones was implanted bilaterally in 6 normal horses. The prosthesis consisted of a convex metal alloy component, and a concave ultra-high molecular weight polyethylene component, for implantation into the radial and third carpal bones, respectively. One horse underwent the soft tissue approach only to serve as a control. Effects on joint motion and pathologic changes were monitored over a 6-month period using clinical examination, synovial fluid analysis, electrogoniometry, high-speed cinematography, radiography, and gross and microscopic pathologic examination. Six months following implantation, all horses that received implants would trot, with slight to moderate lameness. Electrogoniometric and cinematographic evaluation of joint motion demonstrated a reduction in amplitude of the carpus in 4 horses receiving implants; however, in 2 horses, the reduction was less than, or equivalent to, that of the control horse. One horse that received the prosthesis was rideable, and was able to run with minimal lameness. Radiography, synovial fluid analysis, and gross and microscopic pathologic examination revealed varying degrees of synovitis and osteoarthritis. Biomechanical alterations of the middle carpal joint and release of wear particles from the prosthesis were considered to be major causes of these secondary changes. Changes in design of the prosthesis, intended to more accurately maintain normal joint biomechanics are proposed. 相似文献
