The article is devoted to the quantitative characterization of dogs and cats’ jejunum mucus membrane echoicity in different functional states (fasting and postprandial period). The object of the study was healthy dogs of different ages and different breeds (17) and cats (14) of both sexes at the age from 1 to 7 years. The studies were carried out at the Pirogov Veterinary Center in Stavropol using a SIUI Apogee 1100 Omni scanner (Shantou Institute of Ultrasonic Instruments Co., Ltd., Guangdong, China) according to the standard technique using a multi-frequency linear sensor with a frequency of 7-12 MHz. Echohomogeneity and echoicity of the intestinal wall was determined by the method of Silina T L, et al. (2010). Animals were examined before feeding with a preliminary 10-12 hour fasting diet, 20, 40, 60, 90, 120 and 180 minutes after feeding with Purina® ready-made dry food. Mucous membrane echoicity of dogs and cats’ duodenum and jejunum does not change after feeding however 64.7% of dogs had single and multiple small inclusions and less often a longitudinal hyperechoic stripe appears in the mucosa. These changes are most expressed from 60 to 120 minutes after feeding and mostly disappear by 180 minutes. Only 21.4% of cats showed the presence of single hyperechoic inclusions in the mucous membrane of the duodenum or jejunum from 40 to 90 minutes after feeding. The described changes in the mucous membrane of the jejunum must be taken into account when an ultrasound scan is performed on an animal after a meal.

The article is devoted to the quantitative characteristics of the small intestine wall layers echoicity of dogs with parvoviral enteritis, their ratio and comparison of the results with the index of healthy animals intestinal echoicity. The object of the study was 53 heterogeneous dogs of both sexes with confirmed polymerase chain reaction diagnosed with parvoviral enteritis at the age from 6 weeks to 7 months. The studies were carried out at the Pirogov Veterinary Center of Stavropol and SD&TVC at FSBEI HE “Stavropol State Agrarian University” on the SIUI Apogee 1100 scanner (Shantou Institute of Ultrasonic Instruments Co., Ltd., Guangdong, China) according to the generally accepted method using a multi-frequency linear sensor with a frequency of 7-12 MHz in B-mode. It was found that each layer of the jejunal wall (mucous, submucosal and muscular) of examined dogs was homoechoic and the intestine echoicity index of sick dogs increased for the mucous layer - 2.54 times, submucosal - 1.1, and muscle - in 1.3 times compared with healthy animals’ index. Intestinal echoicity index determination provides objective information about changes in the main ultrasound parameter during ultrasound of alimentary tract structures.
