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
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
The problems of creating an optimal microclimate in the closed workshops of poultry farms are relevant for the regions of the south of Russia and the Northern Caucasus, especially acute these problems are for Kabardino-Balkaria. The used zoohygienic measures and existing ventilation systems of closed poultry houses need to be improved and adapted to the local natural conditions. The purpose of the work was to research and develop effective ventilation systems for closed poultry houses in hot climates. Existing ventilation systems and zoohygienic conditions in closed-type poultry houses were studied and investigated. According to the results, the main disadvantages of the existing ventilation systems and their low efficiency were established. And on their basis, new technical solutions have been found to create more efficient ventilation systems for closed poultry houses that provide the optimal microclimate: temperature, humidity and pressure. With the active participation of the author, new technical solutions have been developed and proposed, for which two applications for obtaining patents have been prepared: one for a utility model - for a device for moistening and cooling wall ventilation ducts of poultry houses; the second is for the invention - on the method of erecting a cooling system and humidifying the ventilation panels of the supply. During their implementation, these new technical solutions allow creating such a microclimate, thanks to which optimal indicators of productivity and growth, uniformity, efficiency of feed and meat gain are achieved, without reducing the characteristics of the health and well-being of birds. Ventilation is becoming a major factor in microclimate control in closed houses and the epizootological resistance of birds
This article briefly discusses a new innovation (brought to a level that ensures its practical use) method of artificial intelligence: automated system-cognitive analysis (ASC-analysis) and its programmatic toolkit which is called intellectual system "Eidos". A detailed numerical example of the solution demonstrating the technology of creating a veterinary diagnostic test of gastrointestinal diseases of horses is given. As the source data, we use data from the UCI repository, kindly given by Mary McLeish and Matt Cecile (Department of computer science of University of Guelph, Ontario, Canada N1G 2W1, with the support of a sponsor: Will Taylor. The developed test is used to solve the problems of diagnosis, decision support and examining the simulated subject area by studying its model. The results of the study can be used by anyone, due to the fact that Eidos the universal automated system, which is a tool of ask-analysis, is in full open free access on the author's website at: http://lc.kubagro.ru/aidos/_Aidos-X.htm, and numerical examples of solving veterinary problems with the use of artificial intelligence technologies are placed as a cloud Eidos-application 129
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
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
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
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
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
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
