In this work, the authors presented the results of monitoring urolithiasis in cats in Krasnodar in the period from 2016-2017. The authors established the sexual, age and breed predisposition of animals to this pathology; the seasonality of the disease was studied. An analysis of the actual data and reports of various authors made it possible to conclude that urolithiasis in cats is a polyethological disease. As a result of carried out hematological studies, the presence of an inflammatory process, which was manifested by lymphocytopenia, an insignificant increase in neutrophils and monocytes, as well as hematocrit, was ascertained. A laboratory analysis of urine showed that urine, as a rule, is turbid with an admixture of blood and sand, precipitating rapidly. The authors found an increase in the volume of urine in sick animals due to the inability to remove it, the specific gravity fluctuated within the limits of 1.015-1.020; pH = 7.5-8. With microscopy of the urine sediment, both unorganized and organized sediments were detected. The ultrasound examination of the bladder showed the presence in its cavity echo-positive particles in a suspended state, as well as sections of the desquamated mucosa
The article provides evidence of the high social value of dogs as the most common among pets. We present the results of determining the main causes of illness in dogs and the role of nutrition in the formation of this indicator: the share of diseases of the digestive system and various metabolic diseases accounted for more than 70 % of the total of substantiated cases to the clinic. We have estimated chemical composition of feed premium, industrial production, assessed according to the standards of the National research Council (NRC) for dogs of small breeds in the period of pregnancy and nursing puppies. We have established the feed requirements of pregnant and lactating bitches (Yorkshire Terrier) for key nutrients and bioactive substances. Recipe is made up and we manufactured food standards NRC from natural ingredients; conducted a scientific experiment to assess the impact of both feed on milk productivity indices of mothers and indicators of growing puppies (body weight at birth, weight gain). We have convincingly demonstrated the advantage of using natural food as from a physiological and economic perspective, as it is accompanied by a marked reduction in the cost of the dog and of the cost of the puppies
Providing the population with basic foodstuffs, sources of proteins, fats, carbohydrates, vitamins and other essential nutrients is one of the main issues of ensuring the security of the country, while the requirement for food safety is paramount. Production of feed additives (concentrates), which improve feed conversion, while being natural and safe for animal health, acquires the greatest importance in the conditions of intensification of agriculture and increasing the competitiveness of livestock farms. Probiotic microflora, which, in competition with pathogenic, displaces the latter from the gastrointestinal tract, can be considered as one of the effective methods of controlling undesirable microflora in the digestive tract. In world science, research is actively conducted in the direction of searching for effective probiotic cultures. A promising way to increase the effectiveness of the use of probiotic feed additives is their addition to prebiotics, for example, including vitamins (antioxidants) and mineral substances (selenium). The purpose of this work was to determine the optimal ratio of biologically active substances contained in the feed vitamin-mineral concentrate, and probiotic microflora contained in the feed probiotic additive Bacell-M, for the development of complex feed concentrate. Using the Harrington's desirability function, the optimum ratio of biologically active substances and probiotic microflora in the recipe of the complex feed concentrate is determined, ensuring the maximum reduction in the serum levels of alanine aminotransferase in the blood serum of experimental animals, which characterizes the normalization of barrier organs
Antibacterial chemotherapeutic drugs, which include antibiotics and synthetic antimicrobial agents, are widely used in veterinary medicine for the prevention and treatment of diseases caused by microorganisms. Antibacterial agents can be classified by type of action and chemical structure. It is also known that when several drugs are used in combination with each other, they interact within the body with each other, which can lead to strengthening or weakening of their action. For these reasons, it is of scientific and practical interest to develop a classification of antibiotics by their characteristics and principle of action (task 1), as well as by mutual compatibility (task 2). The article solves these problems using a new method of agglomerative cognitive clustering, implemented in automated system-cognitive analysis (ASK-analysis). This method of clustering has a number of advantages over the known traditional methods of clustering. These advantages allow us to obtain clustering results that are understandable to specialists and amenable to meaningful interpretation, which are well consistent with the experts ' assessments, their experience and intuitive expectations, which is often a problem for classical clustering methods. The article provides detailed numerical examples of solving two problems. The universal automated system called "Eidos", which is a tool of ASK-analysis, is in full open access on the author's website: http://lc.kubagro.ru/aidos/_Aidos-X.htm. Numerical examples of solving veterinary problems with the use of artificial intelligence technologies are placed as cloud Eidos-applications and are available to everyone
One of the most widespread infections affecting newborn pigs is colibacillosis. The set of factors contributes to the development of this disease: non-compliance with elementary veterinary health regulations of conducting pig-breeding, an error in technologies of contents and feeding, stressful situations, and as a result, emergence of the specific factors contributing to illness emergence (dysbacterioses, activation of conditionally pathogenic microflora). In addition, not always specific prophylaxis of colibacillosis is in due time and successfully carried out that is generally bound to disharmony of antigenic composition vaccine drug and originator of the pathogenic potential. In this connection, use of new agents and ways of improvement of prophylaxis of colibacillosis for pigs is represented a current problem in veterinary medicine. The purpose of this work was studying diffusion of colibacillosis among bacterial infections of pigs and establishment preventive efficiency of colibacillosis anatoxin at vaccination the pregnant pigs. Dispersal of colibacillosis was studied in a complex with use the epizootological, anamnestic, clinical, pathologicoanatomic, bacteriological methods of research and also on basis materials the veterinary reports of economy. Allocation of microorganisms was carried out with use differential and diagnostic, selective mediums, identification − with use of traditional methods of bacteriological diagnostics, on the basis cultural, the tinktorial and biochemical properties. Researches showed what colibacillosis at pigs is registered in 37,5-51,4% of cases and wins first place among infections of pigs of a bacterial etiology. When studying efficiency prophylaxis of colibacillosis with bacterination use the pregnant pigs anatoxin containing three types inactivated by formalin exotoxins of the Escherichia coli, have established decrease in indicators of incidence and lethality also high safety of pigs (96%) concerning Escherichia coli
Pasteurella multocida is an important respiratory pathogen of cattle. OmpH Protein is a major protective antigen of bacteria has been well studied in avian strains. In the literature there are no data available for the study of a variety of sequence of this protein among isolates with cattle respiratory pathology. There have been described several genes associated with the virulence of the bacterium in respiratory disease of cattle, but none of the authors compared the frequency of detection of these genes with the pathogenicity for laboratory animals. The aim of our study was the development of allele-specific PCR to determine Omph-types of Pasteurella multocida and the search for new approaches to assess the pathogenicity of isolates of bacteria. Total amount of 83 isolates allocated from the lungs of calves with respiratory pathology was investigated. All isolates belonged to groups A or D (isolates 63 and 20, respectively). Among isolates of capsular serogroup A we revealed 6 types, most propagation types were A1 and A2. All isolates of capsular serogroup D were one omph- type. In 16 out of 23 farms there were identified isolates of only one omph-type, 4 - 2 types, 3 - three types. The frequency of gene hgbb - hemoglobin binding protein correlated with pathogenicity of isolates for white mice. The developed allele-specific PCR along with hgbb gene detection can be used for screening and studying the properties of antigen and circulating pathogenic isolates and selecting a candidate vaccine strains
Relative to the emergence and wide extension of an antibiotic resistance in infectious agents of animal infectious diseases, the particularly important assessment increases over change of sensitivity of various groups of microorganisms to anti-infective drugs. Results of studying antibiotic sensitivity of the enterobacteria isolated from an intestine of sick calves, and dynamics of its change within three years are presented in article. Results of the research demonstrate prevalence of resistance to the majority of anti-infective drugs (AID) among the Enterobacteriaceae isolates emitted from calfs. To chloramphenicol, neomycin and streptomycin from 100% of isolates E. coli, Proteus, Enterobacter, Morganella, Citrobacter were sensitivity. From AID of group of aminoglycosides gentamycin, from group of quinolones – enrofloxacin was the most effective. The good sensitivity to a polymyxin was shown to 80 % of isolates E. coli, Citrobacter spp., Klebsiella spp. It was established that 66,7 % of E. coli isolates, 57,1 % of Enterobacter spp., 75 % of Morganella, 60 % of Edwardsiella, 42,9 % of Citrobacter spp., allocated from sick calfs, has fastness to 7 AID. At the same time to other AID of a series the appreciable number of multiresistant strains shows weak sensitivity. The tendency of augmentation of number of antibiotic resistance isolates to AID which are widely applied in veterinary practice as time passed. High frequency of the combined resistance to traditionally used antibiotic drugs – to kanamycin (up to 80 %), to tetracycline (up to 85 %) and to chloramphenicol (up to 8 3%) testifies to need of obligatory test for sensitivity to AID before their use
The article is devoted to the use of automated system-cognitive analysis for the study of probiotics for the growth of bulls. Moreover, as growth indicators we have not used live weight, but indices characterizing the shape and proportions of the body of animals. A detailed numerical example of solving the problem using real data is given
14 January 2019 at the website of the higher attestation Commission of the Russian Federation http://vak.ed.gov.ru/87 the information appeared: "About refining of scientific specialties and their respective fields of science where publications are included in the List of peer-reviewed scientific publications, where basic scientific results of dissertations on competition of a scientific degree of candidate of Sciences, on competition of a scientific degree of the doctor of Sciences must be published ". It is reported that according to the recommendation of the HAC for other publications included in the List of groups of scientific specialties, the work on refining scientific specialties and branches of science will be continued in 2019. This work is a continuation of the author's series of works on cognitive linguistics. It offers innovative intelligent technology to automate the solution of the problem formulated by the higher attestation Commission of the Russian Federation above. With the use of the automated system-cognitive analysis (ASC-analysis) and its programmatic toolkit which is intellectual system called "Eidos" directly on the basis of official texts of passports of scientific specialties of the higher attestation Commission of the Russian Federation, there were established their semantic kernels, and then, implemented the automatic classification of scientific texts (articles, monographs, textbooks, etc.) on the specialties and groups of specialties of the higher attestation Commission of the Russian Federation. Traditionally, this task is solved by dissertation councils, as well as editorial boards of scientific publications, i.e. by experts, on the basis of expert assessments, in an informal way, on the basis of experience, intuition and professional competence. However, the traditional approach has a number of serious drawbacks that impose significant limitations on the quality and volume of analysis. Therefore, the efforts of researchers and developers to overcome these limitations are relevant. Currently, there are all grounds to consider these restrictions as unacceptable, because they are not only necessary, but also quite possible to overcome. Thus, there is a problem, the solution of which is the subject of consideration in this article. A detailed numerical example of solving the problem on real data is given as well
The embryo passes a number of the stages caused by high-quality structural changes in development and following them growth periods. The periods of change of development for the periods of growth are critical and are most sensitive to influence of external factors. The developed differentiated mode provides sharp temperature increase of incubation in the critical periods of development of an embryo. High temperature at separate stages of an incubation has displaced metabolic processes of the developing embryo towards lipidic exchange, at the same time the cholesterol indicator in blood of skilled chickens has grown more than twice, and level alkaline phosphatase by 2,5 times. Synchronization of the hatching was reached due to reduction of the periods embryonic and output on about 10-12 of hours. Operating an embryogenesis in the period of incubation there is an opportunity to influence the level of productional processes of chickens during the post-embryonic period, average daily gains of live weight at cultivation of broilers increase on average by 5-7%
