12 Sotnikov A.N., Gulyukin M.I., Stafford V.V., Volodko D.V., Tolmacheva V.A. Diagnosis and prevention starvation of wintering bees

Discusses working with the families of bees in the club in the winter. The death of bee colonies in the apiaries of up to 25% comes from carbohydrate starvation during the winter. Inspection of bees in the club in the winter every 2 weeks does not impact negatively on the life of bees reveals a weakening of the strength of bee colonies suffering from varroatosis or viral diseases and timely replenishment of the carbohydrate feed, preventing death from starvation. Disease of bees (varroatosis, saccular brood, etc.) lead to a significant reduction in life expectancy of bees, weakening their forces in the winter, the early appearance of brood in sick families frequent death from starvation due to separation from the feed during heating of the brood. This is observed in weak families with brood and cores when the first night frosts in autumn. They should either remove the hibernation house, or put in one hive, two through the partition. In the winter the club creates favorable conditions for highly effective acaricide treatment bipin twice with an interval of 24 hours. Key words: wintering bees, starvation, winter feeding, winter club bees, honey, brood, varroatosis, bipin.

14 Anufrienko S.M. Improvement swine intestine microflora by feed additive Farmaflor contents killed lactobacteria

The article presents the data illustrating the positive influence of inactivated bacteria Lactobacillus rhamnosus CNCM 1-3698 (LR) and Lactobacillus farciminis CNCM 1-3699 (LF) on pathogen control. Feed additive Farmarlor consists of lactobacteria and inulin. The product is effectively used for prevention of gastrointestinal diseases of pigs and piglets. As a result of the experiments, it has been evaluated that the use of this feed supplement improves the growth of live weight and immunity of weaners, normalizes intestinal microflora, enhances conversion rate and feed intake. Key words: immunity, lactobacillus, microflora, piglets, production indices.

18 Moukhamedshina A.R. Vaccination and disinfection in industrial livestock production

Vaccination and disinfection in the livestock and modern equipment for carrying out the processes. Key words: syringes, dosing units, large-drop vaccination.

22 Fedorova T.KСhlorine dioxide is a reliable disinfection drug providing biosafety of livestocking enterprises
The creation and maintenance of a high level of biosafety is the most important task for livestock enterprises. Currently various disinfectants are used for this purpose. Each of them has advantages and disadvantages. For example, hydrogen peroxide and peracetic acid gave a quick but short-term effect; formalin is also effective, but carcinogen activity do it not applicable for use in the presence of humans and animals, it requires a long exposure and is not suitable for water disinfection. The search for a universal highly effective disinfectant, which lacks the mentioned drawbacks, highlights chlorine dioxide, which can process premises and equipment (including the drinking and water supply system) in livestock farms, processing and food processing enterprises. Key words: air, chlorine dioxide, disinfection, food industry, livestock buildings, objects of the environment, processing industry, water.

INFECTION DISEASE

25 Koteneva S.V., Glotova T.I., Glotov A.G., Yuzhakov A.G. Genetic polymorphism of bovine viral diarrhea virus detected in calves with respiratory diseases

There are presented data on phylogenetic analysis of the isolates BVD virus revealed in calves during outbreaks of respiratory diseases in dairy farms in Siberia and the Republic of Kazakhstan where at the time of the research specific preventive maintenance of the disease was not performed or was conducted with the use of inactivated vaccines. A highly conserved region of the genome, the 5'-untranslated region (5'-UTR), was used for the analysis. There were tested 24 samples containing the RNA of the virus by PCR results. Circulation of 4 subtypes of the first type virus (BVDV-1) were established among calves with respiratory diseases. The pre-existing subtype was 1b (54 % positive samples). Additionally, BVDV-1d (8,3 %), BVDV-1f (29,2 %) and BVDV-1r (8,3 %) were detected. No virus of the second type (BVDV-2) detected. Subtypes 1f and 1r were discovered in our country in the first time. The circulation of the subtypes 1d, 1f and 1r occurred against the background of the use of inactivated vaccines. Viruses were detected in blood samples and lymphoid organs, less often in nasal secretions, which indicates the presence during outbreaks of respiratory diseases animals with persistent and acute (transit) forms of infection in the herds. Studies on the phylogenetic analysis of BVDV can be used to select and and predicting the effectiveness of vaccines in a particular region. Key words: bovine viral diarrhea-mucosal disease, cattle, genome, nucleotide sequence, PCR, phylogenetic analysis.

31 Casademunt S.G.  Clostridiosis in highly productive cattle
The article describes the most pathogenic for cattle species of clostridia, including causative agents of malignant edema, anaerobic enterotoxemia, blackleg. It's necessary to vaccinate animals to prevent these diseases. Key words: vaccine, clostridia, cattle, toxins.

INVASIVE DISEASE

35 Kjzikov I.N. Systematic approach to the problem of ectoparasites in animal husbandry

One of the most serious problems in dairy cattle has been and still is ectoparasites. A significant share among them is taken by mosquitoes, midges, and horseflies, moreover, livestock farms, camps and pastures are home to a huge number of flies. Mites also cause significant damage in livestock. Means of modern control of fly populations include new generation insecticide asa fly and larvicide Maggot. Preventive measures of control insects and mites also involve the treatment of animals by the external application. Most often, deltamethrin-based drugs, such as Deltanil, is used. Control of ectoparasites ensures prevention of bacterial and invasive diseases in livestock. Only an integrated approach will reduce the risks of economic losses due to ectoparasites. Key words: ectoparasites, flies, mites, larvae, insecticide, larvicide, insectoacaricide, cattle, pasture, repellent.
