The Auxiliary Diagnosis Expert System Of Cow's Limb And Foot Disease

With the development of the country's economy and the improvement of people's living standards,the development of the dairy cow industry in China is accelerating and the demand for milk is increasing day by day.However,there are many factors that affect the milk production of dairy cows,such as food,environment and disease.Dairy cow's limb and foot disease is a disease that causes movement disorders,which can lead to a decline in the productivity of dairy cows.Serious cows are directly eliminated,which greatly limits the development of the dairy industry.Cows have high incidence of limb and foot disease,complicated clinical symptoms,and similar symptoms of multiple diseases make the diagnosis more difficult.In order to assist veterinarians in the accurate differential diagnosis of cows' foot and leg disease,it is necessary to develop an expert system for the diagnosis of cow's limb and foot disease.At the present stage,the application of various disease diagnosis expert systems is very extensive.It combines a large amount of professional knowledge in related fields with computer technology,and solves actual production problems through the level of experts.Due to the frequent occurrence of limb and foot disease in dairy cows and the difficulties in differential diagnosis,this study is based on the fact that computer technology has been widely applied to the diagnosis of various diseases.It focuses on the diagnosis of cows' limb and foot disease and combines the expertise of leg and foot disease with computers combined to build a dairy cow's limb and foot disease auxiliary diagnosis platform.Increased diagnostic accuracy of cow's limb and foot disease through clinical application of limb and foot disease aided diagnosis expert system.The auxiliary diagnosis expert system for cow's limbs and foot disease adopts the B/S three-layer structure model design,the Microsoft Visual Studio 2010 system development environment,Visual C# programming language,SQL Server 2008r2 database and other experimental tools for expert system construction.The expert system for assisting diagnosis of cow's limbs and foot disease adopts the method of artificially acquiring knowledge,collating,summarizing and summarizing the knowledge related to the limbs and foot disease of dairy cows in professional textbooks,medical records,research papers,and reports,a total of 64 kinds of dairy cows' foot and foot disease symptoms were collected and treatment information,604 diagnostic rules,290 disease pictures Combining the database's powerful search function,establish a knowledge base of dairy cows' foot and foot disease,including the limb and foot disease rule database,symptom database,picture database,treatment database,etc.,and limb and foot disease management database,including medical record diagnosis database and limb and foot disease knowledge database,cattle farm basic information database and so on.The system adopts clearer and more flexible production rules to express knowledge,making the knowledge base easier to modify,maintain and update.The reasoning diagnosis of cows' foot and foot disease was conducted with uncertainty reasoning mechanism and forward and reverse reasoning strategies to improve the accuracy of diagnosis of limb and foot disease.The experimental results of this study are as follows:(1)The study successfully developed the " Cow's limb and foot disease auxiliary diagnosis expert system " to realize the diagnostic function of 64 cows' arthrosis.(2)Expert system for assisted diagnosis of cow's limbs and foot disease provides reference pictures for the symptoms.The user can select the symptoms according to the picture and clinical performance,and automatically match in the rule base of limb and foot disease according to the user's selected symptoms.Through uncertainty inference,Finally,the reasoning results are provided for the user's reference.At the same time,systematic treatment of limb and foot disease and preventive measures are given.(3)Increase the management function of cow's limb and foot disease,including medical record management,knowledge query management and basic information management of dairy farms.Improve users' management of cow's limbs and feet and reduce the occurrence of limb and foot disease.
