AGGLOMERATIVE COGNITIVE CLUSTERING OF NOSOLOGICAL IMAGES IN VETERINARY MEDICINE

abstract 1381804033 issue 138 pp. 122 – 139 30.04.2018 ru 11
The article deals with the similarity and difference of nosological images in veterinary medicine using a new method of agglomerative clustering implemented in Automated system-cognitive analysis (ASC-analysis) on a small numerical example. This method is called Agglomerative cognitive clustering. This method differs from the known traditional facts: a) parameters of a generalized image of the cluster are computed not as averages from the original objects (classes) or their center of gravity, and are defined using the same underlying cognitive operations of ASC-analysis, which is used for the formation of generalized images of the classes on the basis of examples of objects and which is really correct and provides a synthesis; b) as a criterion of similarity we do not use Euclidean distance or its variants, and the integral criterion of non-metric nature: "the total amount of information", the use of which is theoretically correct and gives good results in non-orthonormal spaces, which are usually found in practice; c) cluster analysis is not based on the original variables, matrices of frequency or a matrix of similarities (differences) dependent on the measurement units of the axes, and in the cognitive space in which all the axes (descriptive scales) use the same unit of measurement: the quantity of information, and therefore, the clustering results do not depend on the original units of measurement features. All this makes it possible to obtain clustering results that are understandable to specialists and can be interpreted in a meaningful way that is in line with experts' assessments, their experience and intuitive expectations, which is often a problem for classical clustering methods

METHOD OF SELECTION OF QUAILS

abstract 1381804034 issue 138 pp. 140 – 148 30.04.2018 ru 43
The article is devoted to the method of selecting quails. Intensive development of re-fishing requires the development of breeding methods for selecting birds and to carry out early predictions of egg production. Targeted breeding selection is able to influence the mechanisms of correlation dependencies between individual parts of the animal's organism, significantly change even firmly established interrelations, and create new interactions more satisfying the needs of the individual. The research task consisted of establishing links between the parameters of the skeleton and the productive qualities of the layers. The studies were conducted on Texas white quails. We took into account the live weight of the bird, the length of the metatarsal and the third finger, as well as the small and large diameters of the metatarsal. Correlations were established between the length of the pelvic limbs and the live weight of young quails during growth. It is established that the growth of the skeleton ends with the age of onset of puberty. This provides a basis for predicting the live weight, depending on the length of the pelvic extremities. It is established that the live mass is directly related to the egg productivity of quails. Thus, by selecting the birds with the longest plus, it makes it possible for 25 weeks of productivity to increase the egg laying on the initial layer by 5,7 eggs and 6,2 eggs per average laying hen, respectively

CORRECTION OF HOMEOSTASIS OF THE ORGANISM OF LARGE CATTLE AT THE NODULAR DERMATITIS

abstract 1381804035 issue 138 pp. 149 – 159 30.04.2018 ru 54
We have studied biochemical changes in the body of cattle, sick with nodular dermatitis in the initial stage of the clinical manifestation of the disease. It is proved that in case of disease in animals there is a significant increase in the level of creatinine up to 295.5 mg%. The excess of the norm by 82.1%. In treatment, this indicator was significantly reduced (189.2 mg%), but did not reach the upper limits of the norm (162.4 mg%). In the blood serum of patients, the carotene content was reduced to 0.09 mg%, which was restored to normal three days after the start of treatment (1.0 mg%). The glucose level at the beginning of the disease was 18% below normal and reached the lower limit of the norm 8 hours after the start of treatment. When studying the activity of CKK, it was found that the activity of the enzyme in animals before the introduction of a 5% solution of sodium hydrogencarbonate is 82% higher than the upper limit of the norm. After the treatment, this indicator returned to normal. The inorganic phosphorus index did not reach the physiological norm (2.5 mmol / l) before and after treatment, and remained 11.6% higher (2.9 mmol / l), which indicates a violation of mineral metabolism in sick animals. The level of reserve alkalinity began to recover after 8 hours of observation and reached a minimum limit of 48.91 vol. % CO2. During the entire period of the experimental studies, before and after the administration of the drug, there were no significant changes in the biochemical parameters of total protein, calcium, vitamin E and urea. The nature of the established changes varied within the limits of physiological norms. The use of a 5% solution of sodium hydrogen carbonate in nodular dermatitis increases the effectiveness of symptomatic treatment, reduces the likelihood of complications and stimulates the production of specific antibodies against viruses and bacteria. We have recommended intravenous injection of 5% sodium hydrogencarbonate solution to sick animals at the rate of 1 ml per 1 kg of live weight of the animal three times with an interval of 3 days

MONITORING OF ANTIBIOTIC RESISTANCE OF ENTEROBACTERIA

abstract 1371803032 issue 137 pp. 197 – 206 30.03.2018 ru 23
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

DISPERSAL OF COLIBACILLOSIS IN PIGS AND THE WAY OF ITS SPECIFIC PROPHYLAXIS

abstract 1371803036 issue 137 pp. 220 – 229 30.03.2018 ru 36
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

DYNAMICS OF EGG PRODUCTION IN CHICKENS OF VARIOUS BREEDS OF BIORESOURCE COLLECTIONS

abstract 1371803037 issue 137 pp. 230 – 237 30.03.2018 ru 18
The production of eggs is one of the most important indicators of the productivity of poultry, including chickens The main purpose of breeding chickens in the collections of genetic resources - conservation of genetic diversity. The chickens from the collection of genetic resources it is also possible to receive products, for example, in the form of eggs. The account of the egg productivity of the chickens showed that the intensity of egg production varies among representatives of different directions of productivity. The most stable egg-laying was possessed by chickens of breeds New Hampshire, Black Australian, Dutch white. These breeds are bred as breeds of egg direction of productivity. But they are characterized by long downturns in egg production, lasting more than 7 days. Chickens of meat direction by stable, but low intensity of egg production. All the chickens had a short period For all chickens a short period is characteristic, when the egg-laying is kept at a certain level. It is 30-40 days, after which there is a gradual decrease in this indicator. Such a high level of genetic diversity in egg production in gene pool makes it possible to use this bird as a model object for studying its features

THE SPREAD OF COLIBACTERIOSIS OF PIGS IN THE KRASNODAR REGION

abstract 1361802029 issue 136 pp. 179 – 188 28.02.2018 ru 20
The article presents data on the prevalence of colibacillosis of pigs in farms of the Krasnodar region in the period 2010-2016. Colibacillosis is widespread in pig farms of the Krasnodar region. In different years, it was recorded at 32.6 - 55.6% of bacterial infectious diseases of pigs. And only in 2013-2014, in farms of the region colibacillosis was not registered. Among the bacterial pathology, colibacillosis in pigs in the farms of the Krasnodar region is in the first place after staphyloccocus (3 - 15 %), streptoccocus (2-13,7 %), and diseases caused by conditionally pathogenic microflora (17,9-20 %). In the Krasnodar region, we annually allocate different serotypes of E. Coli that vary depending on areas and farms, however, regularly in pigs in the Krasnodar region there are the following serotypes: A8, О20, О119, О26, О86 in Bryukhovetskiy, Dinskoy, Kalininskiy, Korenovskiy, Kurganinskiy, Kushchevskaiy, Labinskiy regions of the Krasnodar territory. According to the reports of outbreaks, colibacillosis in pigs for several years were recorded in the Central, Korenovskiy, Kushchevskaya, Labinskiy, Primorsko-Akhtarskiy, Seversky, Slavyanskiy, Tbilisskiy, Timashevskiy, Ust-Labinskiy districts of the Krasnodar region and in the city of Krasnodar. After 2013-2014, after the total absence of the disease in the region, there were reported outbreaks in 2015 in some farms in the Timashevskiy district, and in 2016 – in Kurganinskiy

PREVENTION OF VIOLATIONS OF METABOLISM IN FRESH COWS

abstract 1361802030 issue 136 pp. 189 – 200 28.02.2018 ru 32
The main diseases of lactating cows occur in the first two months of lactation, i.e. during the production peak of productivity. They are caused by the changes in metabolism during the transition period, which are not supported by adequate changes in the organization of feeding, or rather sufficient to ensure cows with nutrients, which causes a number of closely related diseases. To allocate any of them is not possible, as their manifestation depends on a number of reasons, and depending on situation may prevail one or the other. Among the most common diseases, there are ketosis, milk fever (paresis of maternity), dysplasia of the abomasum, acidosis, mastitis, endometritis, laminitis and leukemia. These diseases cause the greatest problems in herds with high productivity, and are caused by changes in metabolism in cows in the transition period and the inability to properly feed the animals at this time. To identify the causes of these diseases we do not need to study each of them individually - it is enough to deal with the peculiarities of metabolism. This period includes the month before calving and the first or second month of lactation, but the most important are 3 weeks before calving and 3 weeks later. In order to prevent metabolic disorders there were developed and tested feed for feeding cows before calving and immediately after calving. Their effect was studied on milk production and health status
