THE RESULTS OF ELECTROGASTROGRAPHY STUDIES OF STOMACH OF HEALTHY PIGLETS
Swine breeding is one of the most productive branches of farming industry. Pigs being adaptable and prolific animals have better feed digestion and higher meat yield per feed unit. But a reverse side is their biological “early maturation” expressed in high susceptibility to stress and effects of environmental factors. The study was conducted at the Department of Therapy and Clinical Diagnostics of the Buryat State Agricultural Academy. Altogether, 140 electrogastrograms were recorded from 7 healthy animals at different times. The study involved recording of stomach bioelectric potentials - of the cardiac, fundic and pyloric departments in clinically healthy pigs. The technique which enabled recording the electrical potentials directly from the muscle membrane of the organ was used. Electrogastrography (EGG) studies were conducted in specially equipped laboratories of farms or veterinary hospitals. When analyzing the EGG records, we used a descriptive method and quantitative assessment. The descriptive evaluation method revealed the regularity of the arrangement of potential fluctuations, increase, or conversely, decrease in stomach bioelectric activity during the recording. The EGG length was measured with curvimeter. The results of stomach EGG analysis are presented after the variational processing. It has been found that the magnitude of bioelectric activity of different stomach departments is significantly affected by the functional state of the digestive tract; the pyloric part of pig stomach in a state of hunger are characterized by high values of electrogastrogram indices. After feeding, the electrical activity of this stomach part is inhibited (SVA - 1.1±0.05 mV). Additionally, each part of the stomach is characterized by a particular wave form in electrogastrogram and the regularity of wave location on the curve.
