Abstract. For a more complete understanding of the effects of external factors on the organism of rabbits adapted to different habitat conditions, it is necessary to conduct broad comparative anatomical studies. Only comparative morphological method with the use of complex morphological, physiological, and chemical techniques will allow us to further explore and justify the structure of the organs and systems of the organism of rabbits. The aim of the study was to research the effect of Bio-mos on the stomach and its blood and lymph sustenance in rabbits of the California breed. Material for research were carcass from clinically healthy male rabbits (slaughtered at the age of 4 months). Two analogue groups of animals were selected. Morphological studies of the stomach of rabbits of the California breed in norm and in the application of the feed additive Bio-Mos. Presented morphometric parameters of arteries, veins and lymphatic vessels of rabbits of the California breed. On the basis of the conducted researches: the thickness of the mucosa ranges from 0.29 to 1.36 mm; thickness of the muscle membrane – from 0.71 to 2.01 mm. the number of glands in the field of view from 67,6 to 108,9 pcs. The arteries of the stomach of rabbits submitted to the mucous, submucous, muscular, and serous plexus. The celiac artery, the control group animals has a diameter of 3.05 ± 0.002 mm, the experimental group of animals is 3.23 ± 0.01 mm, serves as a source of vascularization of the stomach. Venous blood of the stomach of rabbits is transported by veins of the mesentery into the portal vein of the liver. In diameter and the size of lymphatic vessels no significant differences were established.
Keywords: rabbits, morphology, stomach, blood supply, arteries, veins, stomach, lymph, vessels.
