The diseased sheep should have a comprehensive understanding of the forage and drinking water, understand the circumstances of the prevention of injections and insecticide baths, grasp the conditions of the pens and their surrounding environment, grasp the laws of grazing, sports, feeding and weather changes, and understand the past diseases in the herd attachment areas. Occurrence and prevention. Observe the physique, development, nutritional status, mental state, posture and posture, and exercise and behavior of the diseased sheep. Attention to eating, chewing, swallowing, rumination, breathing and other abnormalities. Check the skin elasticity and coat condition and check the color change of the eye conjunctiva. Observe eye, mouth, nose, ear, anus, vulva, and other natural holes for abnormal secretions. After observation, it was found that the sick sheep can do further detailed examination. 1. Assay Temperature measurement is one of the most important routine clinical tests. Changes in body temperature are often used as a primary basis for diagnosing disease. Normal body temperature of the sheep is 38-40C. The normal body temperature of healthy sheep changes slightly during the day and night, generally lower in the morning and higher in the afternoon, with a difference of about 1C. Some infectious diseases and inflammatory diseases tend to increase in body temperature, and high in the afternoon and low in the morning. The body temperature drops during major bleeding, paralysis, circulatory failure, and some poisoning. Temperature measurement is usually performed with a thermometer in the rectum of the sheep. The mercury thermometer of the thermometer should be thrown below 35C before measurement. Set the sheep in good condition, put a little lubricant on the thermometer, insert it into the rectum, stay for 3-5 minutes, then take out and sterilize it with alcohol, look at the height of the mercury column, and measure the temperature once a day and every time in the afternoon. 2. Determine the number of breaths Standing on the back of the abdomen of the affected sheep, observe that the chest and abdomen are accompanied by one breath and one breath, counting the number of breaths per minute. Healthy sheep breathe once a minute. Hyperventilation is common in febrile diseases, painful diseases, hypoxia, etc.; hyperventilation is seen in the production of sputum, certain encephalopathy or food poisoning. Determine the pulse at the sheep's internal femoral artery, gently press with 2-3 fingers, and apply appropriate pressure, feel pulse beat, record the number of beats in 1 minute. Healthy sheep's pulse is 70-80 times per minute. 4. At the time of palpation of the sheep's disease, most of them have disorders of digestive function, and often appear to have symptoms of rumen plot or pro-stomach relaxation, which can be checked by palpation. During the inspection, the left abdomen of the diseased sheep was placed on the left side of the flank to feel the ruminal motility of the rumen. The health of the sheep's rumen peristalsis was 2-4 times per minute, and the peristalsis was strong and powerful, which could lift the hands of the person and continue. The time is more than 15 seconds. Then press the upper, middle and lower parts with the palm of your hand. The upper part of the normal sheep is elastic, the middle part is soft and the lower part is strong. When the rumen accumulates food or the anterior stomach relaxes, the abdominal wall is tight and the contents are hard. If it is mixed with gas and liquid, it is semi-liquid and touches a sense of volatility. If the contents are hard, there is an indentation after pressing. 5. Examination of surface lymph nodes Lymph nodes, sub-auricular lymph nodes, pre-anterior lymph nodes, and superficial inguinal lymph nodes are frequently examined clinically. The swelling of the lymph nodes is a fever, indicating inflammation around them. China Agricultural Network Editor
