The article presents results of a comparative study of
the experimental groups of Holstein animals
belonging to the Reflection Sovering line: four groups
of repair calves and four groups of bull-calves. The
peculiarities of their growth and development were
studied at higher daily rates of drinking milk and early
training of experimental animals to plant feeds with a
probiotic supplement of cellobacterins in the milk
period. The technology of growing the animals of the
experimental groups had differences: I-control group -
up to 6 months of age was grown according to the
traditional technology for farming: 200 kg of milk (for
50 days) and 400 kg of return (from 50 to 110 days),
concentrated feeds consisted of starter feed (50%)
and (50%) maize, the same amount of concentrated
feed and the same composition was obtained by
calves from experimental groups; II-test group - up to
6 months of age received an increased amount of milk
(for 25 days) - 200 kg and 400 kg of return (from 25
to 60 days); animals of the III-rd experimental group
- up to 6-month-old age received an increased rate of
milk drinking (for 50 days) - 450 kg and return (from
50 to 110 days): heifers - 600, bulls -800kg. Animals
of the IV-experimental group-up to 6 months of agereceived
an increased rate of milking (for 60 days) -
450 kg and return (from 60 to 120 days): heifers -
600, bulls -800 kg. The calves of all experimental
groups were fed a probiotic preparation of
cellobacterin in an amount of 3 g for each animal up to 18 months of age. The live weight changed
significantly depending on the age and the level of
feeding of the experimental animals. The use in the
feeding of calves of experimental groups of increased
daily average milk yields and the addition of a
probiotic to cellobacterin in the diet positively
influenced the growth and development of
experimental young animals, promoted a more
intensive increase in live weight
The article provides an overview of domestic and foreign patent information on existing recipes and methods for producing complex feed additives containing probiotic microflora for cattle. Introduction of probiotic cultures of microorganisms to feed additives, along with biologically active substances, allows us to influence the processes of microbiocenosis of the intestines of animals, and, therefore, digestibility and digestibility of feed, which, in turn, leads to an increase in animal productivity. In addition, probiotic cultures contribute to the biodegradation of mycotoxins, which helps prevent mycotoxicity of animals. The most popular in modern livestock breeding are complex feed additives with broad-spectrum probiotic preparations, performing various biological functions
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 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
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
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
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 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
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
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
