This article is devoted to the study of various laboratory tests for the diagnosis of viral peritonitis of cats, conducted in 2014-2018. The study was subjected to 278 cats of both sexes, different breeds and mongrel, of different ages, which were taken to the veterinary clinic «Vita» and the veterinary clinic «Noah's Ark» in Krasnodar. Analysis of the results showed that in the diagnosis and differential diagnosis of viral peritonitis of cats, the most resultant is a combination of studies of Globulin in serum and a test for antibodies to coronavirus, or a solid enzyme immunoassay (tIFA) on IgG to coronavirus. In addition to clinical symptoms, routine laboratory studies, instrumental studies for the diagnosis of viral cat peritonitis, it is necessary to use additional research methods, although many of them have a number of shortcomings in sensitivity and specificity
The authors of this article have developed a questionnaire for pet owners and conducted a research on the nutrition and health of domestic dogs and cats in the urban environment. By results of researches, it is concluded that in the conditions of the city, cats are a preferable type of pets. The preferred type of food is mixed one, with using dry, natural and wet food. Food standards are followed by 46% of owners of 100% participants of the survey and only 43.3% from consulters with veterinary specialists in the field of feeding of a pet. Among non-communicable diseases, urological diseases are more common: urolithiasis, cystitis, endometritis and ovarian cyst
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 article gives results of a comparative study of the growth and development of young cattle of Holstein breed belonging to the Reflection Sovering and Vis Baidial lines, born with the method of transplantation of embryos, and their coevals born with a standard method. Technology of growing of young cattle in both groups was identical, accepted in the economy. During suckling period, the heifers got 300 kg of full-milk. During a period from 3 to 8 months, they were contained in cages for small group maintenance, from an 8 month age, they were contained loose, on pasture grounds. Living mass and average daily increases of experimental heifers changed differently. The rates of height and average daily increases in an experimental group turned out to be higher, than for coevals of the control group. It is proved by the researches, that heifers born with the method of transplantation of embryos are equal to ones who were born with a traditional method in the rates of height and development and even excel coevals at the certain periods. In the age of the first insemination, living mass of heifers of the experimental group was 365 kg, which was 14 kg more compared to coevals of the control group. In all studied age-related periods, heifers of the experimental group excelled coevals of the control group in average daily increases. From their birth and up to 14-th month age, exceeding on increases was 37gr; to the age of the first insemination, heifers of the experimental group were more developed. Taking into account the genetic potential in heifer embryos and their best height and development, it proves the expediency of the use of transplantation of embryos
This article is devoted to the study of the species structure of helminths of the American mink, raccoon and wolf, conducted from 2006 to 2017. The study was subjected to 69 corpses of American mink - 30 of reed-bed, 22 flat, 17 of the Piedmont; 42 dead raccoon to 21 of the foothill and mountain; 24 corpse of the wolf - 8 from overflow land, foothill and mountain landscape-geographical zones of the Northwest Caucasus. The analysis of the results of the study showed that the determining factor in the formation of helminthocenoses of American mink, raccoon and wolf is the species structure of trophic-epizootic chains, the links of which are these predators, as well as species that act as intermediate, additional and reservoir hosts. Feature of helminthiases in carnivorous mammals is determined by a group of fodder. A dynamic increase in the number of species in the structure of helminthocenoses of American mink, raccoon and wolf was established, which is due to the anthropogenic transformation of natural ecosystems, violation of historical biotic relationships, including in the "parasite-host" system. The analyzed species of wild carnivores are involved in the support and formation of natural foci of such hazardous parasites as metros, Alaris, pseudamphistomum, mesocestoides, echinococcosis, trichinosis, dirofilariosis
The article presents the results of a study of the features of growth and development of young bulls in the conditions of Central Yakutia when mineral feed additives are included in their rations. The scientific experience was carried out on the basis of the cattle-breeding farm "Churapcha". For the experiment were selected bullhead Hereford breed at the age of 7 months. Experimental groups of animals were formed by the method of analogues. Such indicators as age, live weight, fatness, physiological state were taken into account. The control group of bulls received the main ration. In comparison with the control group, analogs with I experimental group, in addition to the basic ration, received zeolite 0.5 g / kg body weight, 150 g sapropel and 0.04 g potassium iodide. The animals of the II experimental group received, in addition to the basic ration of zeolite hongurin, at a dose of 0.7 g / kg body weight, 200 g of sapropel with 10 g of copper sulphate. The duration of scientific experience - 7 months. Studies have shown that the addition to the diet of mineral feed additives has influenced the growth and development of bulls. So, when the age of 15 months was reached, according to the compactness index, the bulls of the control group were slightly inferior to their peers by 0.9 % compared to the first experimental group and 5.8 % to the second experimental group. According to the massiveness index, gobies of the I and II experimental groups exceeded the gobies of the control group by 0.5 % and 0.3 %. Upon reaching the age of 15 months on the index of compactness, the bulls of the experimental groups had the best indicators
A number of authors (Milaeva I. V., Zaitsev S. Yu., Dovzhenko N. A., Tsarkov D. V., Tsarkova M. S., 2015) have proposed a regression model and a method for indirect measurement of fat and protein content in cow's milk by its dynamic surface tension, which has a number of advantages over the traditional approach. The model reflects the objectively existing relations between the content of fat and protein in cow's milk and parameters of centigrams of dynamic surface tension at the interface of the milk/air. These relationships are revealed by the authors of the method wit mathematical processing of 112 empirical samples. For this purpose, they have applied regression and correlation analysis (in MS Excel). Since the content of fat and proteins in milk largely determines its quality, this problem refers to the problems of qualimetry. However, this problem of qualimetry also refers to typical problems of pattern recognition (multi-parameter typing and system identification), and therefore it is possible that the quality of its solution can be improved by the use of artificial intelligence methods, in particular cognitive and information technologies. Moreover, these relationships are quite complex. The use of intelligent technologies also creates additional opportunities for the study of the simulated subject area by studying its model. All this is of great scientific and practical interest for both researchers and practitioners. To solve all these problems in the work we have applied Automated System-Cognitive analysis (ASC-analysis) and its software tool which is an intelligent system called "Eidos". A numerical example based on real data has been considered in detail as well
This prospective study was conducted on 10 commercial dairy herds, over one year on milk urea monitoring, determination of diets characteristics effects on MU concentration and on assessment of MU concentrations as a predictor of N utilization and urinary N excretion. Milk samples were collected twice every month and analyzed for urea concentration using a colorimetric procedure. Representative feed samples were also collected on the same day of milk collection. Feed samples were characterized and their concentrations of protein digestible in the intestine and net energy for lactation were calculated according to the French system as well as PDI requirements. Average of milk urea concentrations range is 25.0 - 32.0 mg/dl. A significant positive association (p
Currently, in the Krasnodar region the indicators of
cow productivity are steadily increasing. This was
facilitated by two factors: the improvement of animal
genetics and the introduction of innovations in
technology. Novoplastunovskoe is one of the first
farms, which paid much attention to a significant
change in the technology of dairy cattle. Work began
with the construction of barns "light type" with walls
in the form of opening curtains for the American
project. The premises are equipped with "boxes" for
individual rest of animals with bedding in the form of
sand; automatic heated water logs; on the roof there is
a transparent skate, providing an increase in lighting
and additional ventilation; ceiling fans and additional
water sprinklers are installed to regulate the
microclimate. The milking parlor is equipped with
high-tech equipment and is integrated with the Israeli
computer program “AfiFarm”. Research was carried
out on an estimation of zoohygienic conditions in the
winter and summer periods; the technology of
processing and clearing sand - bedding for animals is
studied; the interior and exterior characteristics of the
cows of the Ayrshire and Holstein breeds adapted to
the new conditions have been determined; with the
help of the computer program “AfiFarm”, the
dynamics of single and daily milk yields, the content
of fat and protein in milk; calculated economic
indicators of milk production from different breeds of
animals
There are many opinions on the question of what kind of society we live in at the beginning of the XXI century. Previously, it was believed that this is a post-industrial society. There was even an opinion that it would be a society of developed socialism or even a communist society. After that, the opinion on this has changed. First, modern society was called the information society, and then the society based on knowledge. The latest news in this area is that it seems that modern society is a digital society, that is, a society, based on digital technologies, digital communications, digital information processing and transmission technologies, as well as digital artificial intelligence technologies. In a digital society and science people must move to digital intelligent research technologies. In particular, the question arises as to whether veterinary medicine in a digital society should not also become cognitive veterinary medicine. This work is devoted to a detailed and reasoned (according to the authors) answer to this question. The methodology and terminology in this new field is not yet established and is not generally accepted. Therefore, in this work a lot of attention is paid to the logic and methodology of scientific knowledge, terminological issues and definitions of concepts
