      Other medicines

      Vetrabutine (Monzaldon 100 mg/ml Solution for Injection below) is recommended by some practitioners for porcine parturition, but the evidence for its effectiveness is not strong.

      Poultry Medicines

      In commercial situations, antimicrobials are initially supplied to poultry in the drinking water and then, if required, the same antimicrobial can be included in the food. In backyard flocks and individual birds, injectable antimicrobials licensed for other stock can be used under the cascade principle. Hence, the ambulatory practitioner does not normally need to carry specifically licensed poultry products.

      Cattle Medicine

      Introduction

      The chapter starts with a brief discussion on carrying out a clinical examination and taking a case history in cattle practice. This is followed by an account of cattle medicine which is organized by system, with sections on diseases of the gastroenteric system, diseases of the neurological system, metabolic diseases (which can also be viewed as a category of neurological diseases), diseases of the respiratory system, diseases of the circulatory system, diseases of the urinary system, diseases of the reproductive system, diseases of the locomotory system and diseases of the integument. Lastly, there is a brief section on the common reasons for cattle to be found dead.

      Clinical Examination, Including History Taking

      The clinical examination is the vital start for making a diagnosis in cattle practice. The respiration rate in the normal adult animal is 12-30 breaths/min, with a quicker rate of 20-24 breaths/min in calves. The pulse rate, which should normally be 60-80 beats/min can be taken from the coccygeal artery at the same time as taking the rectal temperature, which should be between 38 and 39 °C. Also, while in this area of the animal, an abnormal pulse in the urethra of male animals can be felt. The normal pulse rate in calves lies in the range of 70-120 beats/min and the normal rectal temperature is between 38.5 and 39.5 °C. Auscultation of the heart should reveal a steady
