AGGLOMERATIVE COGNITIVE CLUSTERING OF NOSOLOGICAL IMAGES IN VETERINARY MEDICINE
06.02.00 Veterinary and Husbandry
Description
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

CORRECTION OF HOMEOSTASIS OF THE ORGANISM OF LARGE CATTLE AT THE NODULAR DERMATITIS
06.02.00 Veterinary and Husbandry
Description
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

SELENIUM IN BLACK LEACHED SOIL
Description
The content of selenium in the soils of various genetic types varies widely. Its amount is lower in soils formed on volcanic rocks. On average, it is 0.2-0.6 mg/kg. In the soils formed on sedimentary rocks, the content of selenium is often in the range of 4.5-5.0 mg/kg and depending on the conditions of formation it varies widely, sometimes reaching 100 mg/kg. Predominantly they are alkaline soils, selenium concentrations in the soil solution is 10-6 moles. The content of selenium in most soil types of the Russian Federation and CIS countries varies in the range of 0.01-1.0 mg/kg. Floodplain, chestnut soils, black soils and gray soils are more enriched (0.3 to 1.0 mg/kg), whereas sod-podzolic and sandy soils are relatively depleted (0,05-0,2 mg/kg). Systematic application of mineral fertilizers on the fields of crop rotation leads to a decrease in total content in the leached black soil. Fertilizers contribute to increased mobility of this element and more intensive involvement of it in the biological cycle

Description
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

Description
As a result of 12-year research, we found the influence of management and control factors on the population of pests and disease damage of four varieties of winter wheat in KNIISH of P.P. Lukyanenko in order to optimize the plant protection factor. The quantitative characteristics of populations of pests and diseases essentially depend on the agronomist and weather predictors. It has been established that for 8 years the population of winter wheat by the larvae of cereal leaf beetle was higher than the EPO and the protection has been important economically and agro-politically. The maximum population of spikes of wheat thrips was observed in 2009, 2010, 2013 and 2014 and amounted to 24.2-35.3 specimens / spike, which was the basis for the use of insecticides. With optimal weather predictors in 2010, 2011, 2012 and 2013, the population of spikes with larvae of wheat mosquito (without plant protection) was from 15.3 to 19.0 specimens / spike, which is higher than the EPO. Monitoring of the dynamics the development of diseases allowed conclusion that the state of the population of pathogens is limited by the levels of fertility and mineral nutrition and weather predictors. The isolation of the values of these indicators in different periods of development of pests allows to optimize the implementation of operational measures with the contribution of the plant protection factor to the productivity of winter wheat from 7 to 42%
