Is there a vet? Sheep's neck hurts and peas begin to grow on their faces. Etiology, how to treat?

Basic control technology 1. Judge: whether the sheep is sick or not. Feeding managers should pay attention to observing the behavior changes of individual sheep and even the whole flock, generally observing the overall fatness, gait and posture of the sheep, mainly observing the changes of fur, skin, mucosa, conjunctiva, appetite, defecation, respiration and body temperature from the individual sheep, so as to determine whether the sheep is sick and make timely diagnosis and treatment. (1) Fat and thin: chronic wasting disease. Due to the long-term effect of pathogens, the sick sheep are thin. (2) Posture: Observe whether the behavior of the sheep is the same as usual. If it is different, it may be a sign of illness. (3) Gait: Healthy sheep have a lively and stable gait, while sick sheep are unstable or unwilling to walk. (4) Coat: The coat of healthy sheep is smooth, not easy to fall off and full of luster; When sick, the coat is rough and fluffy, loses its luster and is easy to fall off. (5) Skin: The skin of healthy sheep is elastic. Observe the skin color of sheep, whether there is hair loss, skin thickening and hardening, edema, inflammation, trauma and so on. (6) Mucosa: The drilling membrane of healthy sheep is smooth and pink. If the mucosa is red, the body temperature may rise and there is inflammation in the body; If the mucosa is red, with red spots, bloodshot or purple, it may be caused by poisoning or infectious diseases. (7) Appetite: The number of sheep eating grass or drinking water suddenly increases or decreases, and they like licking soil and eating grass roots, which is also a symptom of illness, which may be chronic malnutrition, such as lack of vitamins or trace elements. If the color reversal decreases, weakens or stops, it means that the sheep's forestomach is sick. Sometimes sheep's failure to eat may be caused by oral diseases, such as laryngitis, pharyngitis, oral ulcer, tongue injury and so on. (8) Feces: If sheep dung has a special smell, it can be seen in various enteritis. If there is a lot of mucus in the feces, it means that there is catarrhal inflammation in the intestine; If there are complete particles or crude fibers in the feces, it means indigestion; If there are parasites or parasite segments, there are parasites in the body. (9) Breathing: Normal sheep breathe 12-20 times per minute. The increase of breathing time is seen in febrile diseases, respiratory diseases, heart weakness, anemia, increased intra-abdominal pressure and so on. The reduction of breathing times is mainly seen in some diseases, such as poisoning, metabolic disorder, coma and so on. (10) Body temperature: You can know whether the sheep has a fever by touching the ear or putting your hand into the sheep's mouth and holding your tongue. Of course, the most accurate method is to measure with a thermometer. When taking the temperature of the sheep, first throw the mercury column of the thermometer below 36℃, then apply oil or water, slowly insert it into the anus (1/3 of the thermometer stays outside the anus), and take out the thermometer reading after 2-5 minutes. The normal temperature of sheep is 38-40℃. If the body temperature is higher than 40℃, it means that there is a fever disease.
