The use of low intensive red spectrum laser radiation for prevention of abomasoenteritis in calves is effective method. As a result the increase of erythrocytes level and saturation of them with hemoglobin happens. Natural resistance with bactericide and lysozyme activity are going up phagocytosis of neutrophils is activated. The most successful method are magnet-laser radiation of blood and laser acupuncture. There was studied the low intensive red spectrum laser radiation for prevention of abomasoenteritis in calves. During the research it is established, that preventive efficiency at abomasoenteritis in the first trial group has made 80%, in the second and the third - 90%. As a result of the spent work high preventive efficiency of action of the low intensive red spectrum laser radiation is established at prescription of through-skin blood irradiations by the therapeutic laser in a combination to a constant magnetic field and as a result influences on biologically active points. Application of these ways allows to reduce level of disease of animal abomasoenteritis. As a result of physiotherapeutic influence there is content increase of erythrocytes in blood of calves and saturation their haemoglobin. Natural resistance with bactericide and lysozyme activity are going up phagocytosis of neutrophils is activated. The most successful method are magnet-laser radiation of blood and laser acupuncture. It is caused by that positive changes occurring in an organism, have been more brightly expressed and besides preventive and economic efficiency of these ways of irradiation also were at higher level. In the tabular form dynamics of morphological indicators at calves under the influence of laser radiation, dynamics of indicators of natural resistance at calves as a result of the laser therapy, some biochemical indicators of blood is presented at carrying out of research.

There was studied the therapeutic efficiency of sorbent Lactofiltrum in a complex therapy of abomasoenteritis at calves. It represents the complex preparation containing 75% of hydrolytic lignins and 25% of lactulose. Action of lignins is based on ability to sorb and strongly to keep toxins of exogenous and endogenous origins, the pathogenic microorganisms which are present in enteral mediuim. Lactulose, a part of prebiotics Lactofiltrum, is a synthetic disaccharide. It is not exposed to splitting by enzymes in thin intestines. The active substance lactulose starts to operate in a thick gut where under the influence of intestinal microflora it is transformedto low-molecular organic acids, basically dairy, acetic, oil and propionic. Thanks to acidification of intestinal contents growth of putrefactive and pathogenic microflora chokes, osmotic pressure in a gleam of a thick gut increases. Lactofiltrum possesses high therapeutic efficiency. The experiment has shown 100% effectiveness in treatment. Economic effect is 1,63 rubles in control group and 3,52 rubles in experimental group from 1 ruble of expenditure. This treatment is economically profitable. In the tabular form the content of the general bilirubin, cholesterol, triglycerides and glucose in blood serum, urea and creatinine, daily average body weight gain and epizooty, morphological indicators of blood, dynamics of the general protein and albumens at calves with abomasoenteritis are presented. Lactofiltrum has a high therapeutic effect. Pharmacology action is associated with intestinal digestion normalization due to absorption of toxins and useful bacteria stimulation. The experiment has shown 100% effectiveness in treatment. This treatment is economically profitable.
