In the conditions of the Republic of Belarus clinic and production conditions there was analyzed the prophylactic and therapeutic efficacy of a new national complex iron dextrane preparation Ferovital against deficiency (nutritional) anemia of new-born cattle and swine. In course of the study there were analyzed results of hematological and biochemical tests of blood of piglets which were administrated with Ferovital preparation. There were also marked the general economic index: live weight gain, disease incidence, piglet death rate, etc. Research results showed that the Ferovital preparation had an expressed prophylactic and therapeutic efficacy both in clinic and production conditions.

In the conditions of the Republic of Belarus there was studied the influence of high degree of cow productivity on the course of down-lying and state of endocrine status of animals and their reproductive qualities. Application of veterinary preparations Katozal and Ovoton made it possible to control the functional activity of cow dam and ovary providing the increasing of cow reproduction qualities. Results of tests of estradiol-17 beta and progesterone in blood serum of experimental and control groups cows were presented. Application of Katozal and Ovoton veterinary drugs made it possible to cause heat and insemination of 86,5-91,3% of cows. At the same time, according to the results of the first insemination the highest results were obtained at cows with low productivity indexes – 60,9% and according to productivity increasing this index lowered up to 32,7% and 29,8%, respectively. According to the results of all insemination in cases of 3500-5000 kg productivity only 2 cows (8,7%) were nonbearing.

Results of treatment and preventive maintenance of mastitis of lactating nonmilking cows and heifers with the help of a new probiotic preparation Lactosan realized in the conditions of the Republic of Belarus were presented. The developed new environmentally safe antimastitis preparation Lactosan contained lactic acid bacteria Lactobacillus plantarum and Lactobacillus acidophilus in amount not less than10E7 CFU/cm3 did not render irritating action on mucous membranes, did not cause a sensitization and according to its toxicity indexes could be concern to low-hazardous substances. Therapeutic effectiveness of Lactosan against subclinical mastitis was 84,2-94,1%; in case of serous and catarrhal mastitis – 63,2-68,4%; and after two therapy regimen – 79,0-84,2%.

In the conditions of the Republic of Belarus there was realized a morphological study of bone marrow aspirates at different terms chicken of immunization against Gumboro disease which made it possible to analyze the state of immune system for the objective evaluation of immunological status. Research results showed that chicken immunization with a national liquid chick embryo viral vaccine produced on the basis of KMIehV-13 strain against Gumboro disease (infectious bursal disease) promoted the development of immunomorphological remodeling of bone marrow. Application of immunostimulants Alveozan and Nukleovit for poultry vaccination caused more expressed changes revealing in statistically reliable increasing of total number of myeloblastic cells in the majority of cases by means of increasing of immature cells, and then mature cells of granulocytic series, as well as quantity of lymphocytes and plasmacytes

The article deals with the prevention problem of digestive system diseases in pig-breeding and therapeutic measures perfecting for these diseases. In article are given new methods of prevention without using antibiotics

Sodium hypochlorite solution is an effective means in control of noncontagious aetiology diseases, accompanied by development of endogen intoxications. The detoxification action of sodium hypochlorite is that in the body there is no becomes free active oxygen, oxidizing there toxic and ballast substances as bilirubin, urea, ammonia, uric acid, creatinine, cholesterol, carbonic oxide, acetone, acetone acetate, ethanol, methanol, barbiturates, etc. The detoxification action of sodium hypochlorite is shown in neutralization of exotoxins and endotoxins of pathogenic microorganisms as it represents a compound of the small molecular mass and the small structural size. In this connection it freely gets through membranes of cells and oxidizes the toxins containing not only in blood, but also in cells. From this follows, that sodium hypochlorite models not only oxidizing function of cytochrome Р-450 of liver, but also phagocytal function of neutrophilic leucocyte. It leads to inactivation of large toxic molecular compounds both on a surface of uniform elements, and in blood plasma while effective methods reduce intoxication at the expense of removal of the average molecules circulating in plasma
