Horse-Expert: An aided expert system for diagnosing horse diseases

In contrast to the rapid development of the horse husbandry in China, the ability of horse veterinarians to diagnose diseases has not been improved and only a few domain experts have considerable expertise. At present, many expert systems have been developed for diseases diagnosis, but few for horse diseases diagnosis have been studied in depth. This paper presents the design and development of a computer-aided expert system for diagnosing horse diseases. We suggest an approach for diagnosis of horse diseases based on the analysis of diagnostic characteristics and the experiential knowledge of domain experts. It is based on using evidence-weighted uncertainty reasoning theory, which is a combination of evidence theory and an uncertainty pass algorithm of confidence factors. It enables drawing of inferences with atypical clinical signs and the uncertainty of the user’s subjective understanding. It reduces the influence of subjective factors on diagnostic accuracy. The system utilizes a user friendly interface for users and requests a confidence factor from users when feedback is given to the system. Horse-Expert combines the confidence factors with weight factors assigned to clinical signs by experts during the knowledge acquisition process to make diagnostic conclusions. The system can diagnose 91 common horse diseases, and provides suggestions for appropriate treatment options. In addition, users can check the medical record through statistical charts. The system has been tested in seven demonstration areas of Xinjiang province in northwestern China. By constantly maintaining and updating the knowledge base, the system has potential application in veterinary practice.

Порівняльний аналіз епізоотологічної ситуації щодо кишкових гельмінтозів примітивних порід коней

Наведено результати моніторингу епізоотологічної ситуації щодо інвазійних захворювань коней примітивних порід, проведеного у конегосподарствах різних форм власності з різними типами утримання в Україні (Львівська, Івано-Франківська, Закарпатська області) та Польщі (Варміно-Мазурське воєводство). Встановлено, що тварини були інвазовані: нематодами (кишкові стронгіліди, параскариси, оксіури, габронеми), цестодами (аноплоцефали) та найпростішими (еймеріями). Клінічні прояви гельмінтозів залежать як від рівня зараженості коней, так і від збалансованості раціону та забезпечення кормами. We held monitoring of epizootic situation that deals with invasion of horse diseases that had been held in the horse farms of different forms of ownership and with different types of allowance in Ukraine (Lviv, Ivano-Frankivsk and Transcarpathian regions) and in Poland (Wojewуdztwo Warmiсsko-Mazurskie). We established that the animals were invasioned by Nematodes, Cestodes and by protozoan. Clinical manifestations of helminthiasis depend on the level of contamination of horses as well as on balanced rations, food suply.
