In this article, the authors have defined the acute toxicity of Roksatsin preparation, which represents a 20 % aqueous solution of polyhexamethylene guanidinehydrochloride (PHMG). The acute toxicity of Roksatsin in the first series of experiments was studied on white mice upon intragastric administration. In the second series of the experiments, Roksatsin was administered subcutaneously to white rats and in the third series of experiments the preparation was administered intracisternally to cows. The results of the first series of experiments showed that Roksatsin by the internal method of appointment is slightly toxic to white mice. In this experiment not been a single case of acute intoxication and death of animals. Experiments to determine the acute toxicity of the preparation for white rats were performed in triplicate. In the first series of experiment, the LD50 was 4.8 ml/kg. It is found, that the calculated coefficients LD50 for other two series were close to the first one: the second - 4.2 ml/kg and the third - 4.5 ml/kg. Therefore, the authors found that the Roksatsin preparation upon subcutaneously administration according GOST 12.1.007-76 is a low-toxic compound (4th class of danger). As a result of the third series of the experiments, it was found that the intracisternally administration of Roksatsin preparation to cows in a dose of 5 ml is not toxic to the animal organism. Intracisternal administration of Roksatsin does not have a significant impact on the morphological and biochemical indices of blood. On this basis, Roksatsin preparation with different routes of administration is low-toxic and it can be recommended for clinical researches
The authors briefly describe the properties of polyhexamethyleneguanidine hydrochloride (PHMG), which refers to a broad-spectrum biocide and has antimicrobial activity against Gram-negative and Gram-positive bacteria, viruses and fungi. PHMG has a deodorizing effect, gives the treated surfaces long bactericidal effect, which can be stored depending on the surface and other external factors from 3 days to 8 months. The authors have presented data about the level of bacterial and fungal contamination of air in the dispensary before and after aerosol treatment of Roksatsin. Bacterial contamination of air dispensary determined via the sedimentation method (Koch Method), which is settling microflora (in air), under gravity, on the surface of a growth medium. For the determination of total bacteria and fungi in 1m3 of air the authors make calculations of total aerobic microbial count (TAMC) according to the formula that was proposed by V.L. Omelyanskii. Bacterial contamination of air was evaluated before disinfection. Accounting quality of aerosol disinfection performed by sedimentation microflora on Petri Dishes through 30, 60 and 120 minutes of exposition. In the analysis of the data the authors defined that Roksatsin as a disinfectant has a negative effect on pathogens, namely significantly reduced the content of pathogenic and conditionally pathogenic bacteria and fungi in the air, so it can be used for preventive and compelled aerosol disinfection of air in the livestock buildings

Dog poisoning toxicant used at home for rodent
control (often based on zinc phosphide ) is
accompanied by the development of anemia . In
etiopathogenesis of this type of pathology of the
blood we can highlight as important: haemolytic ,
haemorrhagic and allergic components, but the
nature and extent of the changes under there are
unequal. This requires the development of a special
algorithm of examination and treatment strategies of
the animal in accordance with the stages of the
development of the disease. Modern conditions
dictate the need, along with the actions to carry out
urgent medical identification as the main etiological
factor and pathogenesis, and the leading
pathogenetic factors that pose a threat to the danger
of other pathological processes and disease states.
First, we evaluate the extent of damage to the liver,
kidneys, heart, spleen and blood vessels, which is
possible only if the clinic has appropriate methods

Spraying the hatching eggs with disinfecting solution was found to be the effective mean to decrease a risk of bacterial contamination. The most used disinfection means contain quaternary ammonium compounds, phenols, iodine of glutaric aldehyde. However, some disinfectants have ability to close pores on to the egg in case of applicating on the surface of egg that results in decreasing evaporation of water during incubation and decreasing hatching. The most popular methods is gazation with using the preparation on a base of formaldehyde, formalin, potassium permanganate. The above-mentioned methods have the risks of potential danger for hatching eggs and developing embryos. For biocidic treatment of eggs YF-irradiation is used, as well as ozone, but it penetrates into eggs owing to eggs pores and destabilizes embryo. Moreover, ozone possesses the toxic, corrosive and inflammable properties and its using must be controlled. Some disinfectants, especially chloral-containing preparation have a property to react with cuticle of eggshell and falls their activity. Other disinfectants, as a rule, block the pores and make difficult gazoexchanging. Using the preparation on a base of electroactivatel solutions of sodium chloride. Was detected to be one of the perspective approaches to disinfection of hatching eggs. The results of study on a development of disinfection technology for hatching eggs contaminated by bacteria and fungi with using the Super ANK Anolyte
Under the field conditions breeding the young poultry takes place in the eggs out of maternal body. For successful breeding the progeny keeping all the demands to safety and quality of hatching eggs has the important significance. Safety demands are presented in the appropriate Technical Standards (TS). The microbial standards are to be very significant. Moreover, it is necessary to control both the microorganisms note in TS and other species as dangerous factors on during the process of production. The methods and means used presently for disinfection of hatching eggs have some disadvantages, e.g. the method of gazation with using the preparations on a base of formaldehyde, formalin, potassium permanganate; ozone has the toxical, corrosive and inflammable properties and its using must be controlled; chlorine-containing disinfectants have a property to react with cuticle of eggshell and fall their activity. The results of a study on applicating Super ANK Anolyte for biocidal treatment of the eggs are presented in the article
