The technical route of the sheep disease prevention and control expert system is to analyze the system's goals in a closely integrated way by livestock experts, knowledge engineers, computer experts, and Veterinary Ultrasound veterinary imagers. First, livestock experts and veterinary ultrasound experts summarize the knowledge of sheep disease prevention and control to form expert knowledge of sheep disease prevention and control, and provide relevant text, pictures, videos and other original materials. Then, knowledge engineers and computer experts summarize the professional theories and rich experience of livestock experts, as well as the diagnostic knowledge of sheep ultrasound, and use artificial intelligence and knowledge engineering methods to process the knowledge materials of sheep disease prevention and control experts, turning expert knowledge into data that computers can understand and operate, and building a database for storage, and establishing an expert-level knowledge base, rule base and database. Finally, a computer engineer builds a sheep disease prevention and control expert system, which summarizes, infers and makes decisions on sheep disease prevention and control issues based on facts and time, as well as the inspection conditions of veterinary Ultrasound Machines, so as to achieve the use of computer simulation of expert intelligence to guide users to scientifically prevent and control sheep diseases. The overall structural framework of the expert system for sheep disease prevention and control. There are two important components in establishing an expert system. One is the knowledge base, which stores the specialized knowledge obtained from experts about a certain field, such as the knowledge of B-ultrasound veterinary imaging for sheep; the other is the reasoning engine, which has the ability to reason and can deduce conclusions based on the problem, rather than simply searching for ready-made answers. The ability of the expert system comes from the large amount of specialized knowledge it stores (such as B-ultrasound veterinary imaging knowledge for sheep) and the proper application of reasoning technology.

Imported B-ultrasound for sheep

Sheep metritis is an inflammation of the uterine mucosa caused by bacterial infection due to delivery, midwifery, uterine prolapse, vaginal prolapse, retained placenta, peritonitis, and fetal death in the abdomen. Through the analysis of a large amount of data from the veterinary B-ultrasound machine, metritis is also the main reason for the inability to breed.

Sheep metritis can be seen in two types: acute and chronic. According to the nature of the inflammation during the course of the disease, it can be divided into catarrhal, hemorrhagic and suppurative metritis.

In the early stage of acute illness, sheep have reduced appetite, poor spirits, and increased body temperature. Grinding teeth and groaning due to pain reactions. The front stomach relaxes, the back is arched, and the woman strains to urinate. The woman's vagina is filled with dirty red contents. The chronic condition is milder than the acute one, with a long course and less uterine secretions. If not treated in time, it may develop into uterine necrosis, followed by a deterioration of the systemic condition, and sepsis or septicemia. Sometimes peritonitis, pneumonia, cystitis, mastitis, etc. may occur. Prevention and treatment Purify and clean the uterus. Use 0.1% potassium permanganate solution or 300 ml of Xie Erxing (containing 2% ofloxacin) solution to pour into the uterine cavity, and then use the siphon method to discharge the disinfectant solution poured into the uterus. This should be done once a day and can be used for 3 to 4 times. For anti-inflammatory treatment, 3 ml of iodine glycerol can be injected into the sheep's uterus after flushing, or oxytetracycline (0.5 g) capsules can be placed; or 800,000 units of penicillin and 500,000 units of streptomycin can be injected intramuscularly once in the morning and evening every day. For the treatment of autointoxication, use 100 ml of 10% glucose solution, 100 ml of Ringer's solution, and 30-50 ml of 5% sodium bicarbonate solution, injected intravenously once; 200 mg of vitamin C is injected intramuscularly.
