The report presents the results of studying Rift Valley fever (RVF) spatial-dynamic features and revealing the regularities of the infection prevalence worldwide. The developed long-range forecast provides for the trend the RVF epizootic tension will be further aggravating to remain up to 2030. The highest probability of the disease registration in 2017 – 2030 (the range of values is 0.6 to 1.0) is predicted for tropical agroecosystems of the African continent and Arabian & Southern regions of Asia. Also, the forecast for the RVF epizootic situation in the Russian Federation and neighboring countries is given. The RVF nosoarea that potentially might exist in the Russian Federation and neighboring countries is divided into 4 disease occurrence probability zones in terms of the intensity of natural and socio-economic factors & prerequisites . The estimated infection occurrence in the Russian Federation is below the average probability level (namely, within 0,2 to 0,4). Key words: Rift valley fever, epizootological monitoring, stationarity index, incidence index, forecast.

8 Stekolnikov A.A., Ladanova M.A., Tolkachev V.A., Kolomyicev S.M. Prevalence and interrelation purulent- necrotic damage of fingers and obstetric-gynecological diseases in cows under condition of fastened management
This article shows seasonal and age dynamics of diagnosing at purulent - necrotic defeats of tissues of fingers and obstetrics – gynecologic pathology of cow's in the conditions of fastened contents, their interrelation is studied, the community in seasonal and age dynamics of frequency of filing is revealed and it is established that particular types (detention of an afterbirth, an endometritis, mastitis) obstetric and gynecologic pathology promote increase in number of damages of extremities. 280 dairy cows and heifers from the educational-experimental farm "Znamenskoye"of the Kursk State Agricultural Academy were examined. It was established that the predisposition of animals to reproductive disorders increases during service life. The incidence of limb diseases was minimal in summer (12,78 – 13,92 %), in the autumn-winter period it increased to 27,88 % and in the spring – to 29,02 %. In 172 animals, purulent-necrotic lesions of the fingers were revealed, including deformation of the hoof horn (47 animals; 27,32 %), ulcers (33; 19,18 %), arthritis (26; 15,11%), sprains and ligament rupture (12; 6,42 %), pododermatitis (10; 5,81 %), wounds and phlegmon of crumb (16; 9,30 %) and corolla (10;5,81%). Positive correlation between obstetric-gynecological pathologies and diseases of the limbs was noted: with retention of placenta simultaneously were diagnosed the deformity of the hoof cover (8; 8,08 %), wounds and phlegmon of the corolla (4; 4,04 %) and crumb (6; 6,06 %); with mastitis – ulcers in the area of he fingers and pododermatitis (4; 4,04 %); with endometritis – purulent decomposition of the horn sole (3; 3,03 %); with vaginitis-laminitis (2; 2,02 %). Key words: arthritis, vaginitis, laminitis, cattle, mastitis, pododermatitis, wounds, phlegmon, endometritis, ulcer.

It was compared the immunogenicity of the vaccine strains B. abortus 19, 82 and RB-51 in experiment conducted on guinea pigs. These strains were subcutaneously administered to the animals at a dose 109 CFU/ml and strain 19 also by conjunctival method at a dose 108 CFU/ml. Animals were experimentally infected with virulent strain B. abortus 544 at a dose 102 CFU/ml after 90 days post vaccination. Equal amount (80 %) of subcutaneously and conjunctival immunized guinea pigs survived challenged. Also in these groups of animals was the same infection index (1,1). Since the dosage of strain 19 in subcutaneous vaccination was 10 times higher than in the conjunctival vaccination, the last of the above methods should be considered more technologically. Both remaining vaccine strains protected from virulent strain 544 in the same but smaller level compared to strain 19 (60 %). The index of infection in the group of animals immunized by strain 82 was lower than in the group vaccinated by strain RB-51 – 8,8 and 13,9, respectively. In the control group all animals become infected (infection index – 45,6). Key words: brucellosis, experimental infection, immunogenicity, protective effect, vaccine.

24 Vecherkovskaya M.F., Artemenko N.K. Effect of antiseptic drug on biofilms of bacteria causing odontogenic infections in dogs
Dental plaque formation is the most widespread oral condition in domestic dogs. Dental tartar and dental plaque frequently lead to paradontosis, tooth loss, systemic complications. Bacteria comprising dental plaque form biofilms, which allows them to survive and cause disease often despite adequate hygienic measures. Multiple cultures of gram-positive, gram-negative, aerobic, facultative-anaerobic and anaerobic bacteria were isolated from canine dental plaque formations. Strains with the most pronounced ability to form biofilms were selected from those cultures. It was shown that the antiseptic drug based on poly-n1-hydrazino(imino)-methyl-1,6-hexanediamine exhibit broad spectrum antibacterial activity, prevents the formation of biofilms, penetrate, penetrates mature biofilms causing bacterial death. The drug can be use to effectively fight against bacteria causing mouth cavity diseases in dogs. Key words: antiseptic drug, dental plaque, oral microbiota, dog, periodontitis.

43 Batracov A.Y., Yashin A.V., Donskaya T.K., Vinnikova S.V. The metabolic state of highly productive cows, its correction and prevention
The organizational and technological causes that disrupt processes of metabolism in cows' organisms are outlined in this article. The negative influence of unbalanced nutrition, incorrect conditions of keeping and wrongs of selective works to physiology and biology processes was reflected in details. Through such mistakes motor, secret, suction, barrier, immune functions are breaking. Besides functions of digestive, cardiovascular, reproduction, urinary, endocrine and neurohumorous systems are breaking too. In this context, some diseases such as ketosis, hepatosis, nephrosis, endometritis, mastitis, pododermatitis, neonatal dyspepsia appear and become a cause of long infertility. This factors increase the number of culling of animals from the herd premature. Adding fiber, propyleneglycols, glycerol, increase of potassium iodide and cobalt chloride to the ration can normalize physical condition of animals and biochemical blood counts of protein and its fractions, urea, urea's nitrogen, glucose, magnesium and chloridis. Due to this diet correction, prophylactic and treatment of group of cows the morbidity of pododermatitis shortened by 23%, the fecundity increase by 18 %, the period of service shorten by 42 days.

46 Tarnuev A.S., Tarnuev Y.A., Abidueva E.Y. Electrogastrography at horses
In extreme conditions of Zabaykalsky Krai, the Republic of Buryatia and Mongolia the horse is simply irreplaceable as she has high meat efficiency, ability to quickly gain a weight, unpretentiousness to a forage. Horses get forage as wild deer, digging out oddments of herbs from under snow. On endurance they robust and fast on the run, are capable to transfer a hot icy cold, hunger and long driving. Horses of the Transbaikal, Buryat and Mongolian breeds are on year-round pasturable contents. One of the major problems in horse breeding is also body height of incidence among animals which greatest percent is the share of noncontagious diseases. Work is devoted to studying of motor and secretory function of a stomach of horses normal and at pathology by means of an electrogastrography technique, by means of this technique many parties of digestion of pets, birds and fur animals are revealed. Key words: biopotentials, electrogram, the electrode, section of the stomach, muscle wall.
