In the interests of com-pression and simplicity, a single procedure is described in some detail, whilethe alternatives, known to be equally good in the hands of others, are brieflylisted. No apology is made for such dogmatism.The text includes frequent reference to specific types and sizes of instru-ments and suture materials. In view of the current move to the metric system,albeit late in the Anglo-American world, all figures are metric, but a com-parative scale is included.All surgery presents a series of challenges, and this accounts for thepopularity of the discipline in both the veterinary and medical professions.The challenges in bovine surgery differ from those met by the companionanimal surgeon. The first is the economic question: is surgery economicallyjustified? The balance of a judgement to perform a caesarean section on aheifer with dystocia rather than to salvage the animal may be a fine one. Thisis rarely so in the companion animal field. Humane considerations oftencomplicate an otherwise simple problem.Other challenges include the anatomical knowledge pertinent to the proce-dure, the method of restraint and analgesia or anaesthesia, the demands ofmanual dexterity, and the physical stress imposed on patient and surgeonalike, when surgery must be performed in a sub-optimal environment, whichmay be the corner of a field or a dark spot in a dusty cowshed.The inevitable lack of experience in bovine surgery of a young veterinarygraduate may persist as a result of a certain apathy among colleagues inthe practice group. This apathy is reflected in the difficulties of maintainingequipment necessary for emergency surgery, and results in impatience atthe overall time required to complete a bovine operation. The axiom ‘timeis money’ applies as much to the bovine surgeon as to anyone and, sinceproper instrumentation, asepsis, effective anaesthesia and basic techniquesare the keystones to effective craftsmanship, these points are discussed inthe first section.viPreface to First EditionSucceeding chapters logically pass from the head and neck to the abdomen,thence to the female urinogenital system and teat surgery, the male urino-genital apparatus, and finally to lameness. No attempt can be made to treat asubject in depth. The further reading list is similarly selected purely as a basicliterature guide.The reader will often have to consider ethical implications of proposed pro-phylactic or curative surgery. Animal welfare considerations are becomingincreasingly important in many countries. Is castration justified? Is it justifiedin older cattle, either on humane, economic or management grounds? Therelevant veterinary literature is sparse and the conclusions are conflicting.Responsibility rests with the veterinarian.Why does a farm experience an ‘epidemic’ of left abomasal displacementcases? The veterinarian may search for further advice on prophylaxis. Suchan investigation will often involve other disciplines. A multi-disciplinaryapproach is particularly needed in herd lameness problems, and the checklists (see pp. 236–238) should stimulate objective recording of herd dataand take the emphasis away from repetitive back-breaking treatment of theindividual cow.Serving as a prophylactic, diagnostic and therapeutic instrument, bovinesurgery therefore fits into the concept of a herd health programme.A.
