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
14 January 2019 at the website of the higher attestation Commission of the Russian Federation http://vak.ed.gov.ru/87 the information appeared: "About refining of scientific specialties and their respective fields of science where publications are included in the List of peer-reviewed scientific publications, where basic scientific results of dissertations on competition of a scientific degree of candidate of Sciences, on competition of a scientific degree of the doctor of Sciences must be published ". It is reported that according to the recommendation of the HAC for other publications included in the List of groups of scientific specialties, the work on refining scientific specialties and branches of science will be continued in 2019. This work is a continuation of the author's series of works on cognitive linguistics. It offers innovative intelligent technology to automate the solution of the problem formulated by the higher attestation Commission of the Russian Federation above. With the use of the automated system-cognitive analysis (ASC-analysis) and its programmatic toolkit which is intellectual system called "Eidos" directly on the basis of official texts of passports of scientific specialties of the higher attestation Commission of the Russian Federation, there were established their semantic kernels, and then, implemented the automatic classification of scientific texts (articles, monographs, textbooks, etc.) on the specialties and groups of specialties of the higher attestation Commission of the Russian Federation. Traditionally, this task is solved by dissertation councils, as well as editorial boards of scientific publications, i.e. by experts, on the basis of expert assessments, in an informal way, on the basis of experience, intuition and professional competence. However, the traditional approach has a number of serious drawbacks that impose significant limitations on the quality and volume of analysis. Therefore, the efforts of researchers and developers to overcome these limitations are relevant. Currently, there are all grounds to consider these restrictions as unacceptable, because they are not only necessary, but also quite possible to overcome. Thus, there is a problem, the solution of which is the subject of consideration in this article. A detailed numerical example of solving the problem on real data is given as well
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
The article presents modern methods of biotechnology used in dairy cattle breeding to increase the highly productive herd on the example of one of the farms of the Krasnodar region. The embryo transplantation method is described in detail, and a complete scheme of embryo flushing and transfer is presented. Requirements for donors and recipients, as well as for hormonal stimulation of superovulation, high-quality embryos are described. In the example of a three-year use of embryo transplantation in Agroholding Kuban company, the results are given on the number of dairy breeds of black-and-white Holstein cows, milk yield, and the quality indicator of milk. The article also proves economic efficiency
The embryo passes a number of the stages caused by high-quality structural changes in development and following them growth periods. The periods of change of development for the periods of growth are critical and are most sensitive to influence of external factors. The developed differentiated mode provides sharp temperature increase of incubation in the critical periods of development of an embryo. High temperature at separate stages of an incubation has displaced metabolic processes of the developing embryo towards lipidic exchange, at the same time the cholesterol indicator in blood of skilled chickens has grown more than twice, and level alkaline phosphatase by 2,5 times. Synchronization of the hatching was reached due to reduction of the periods embryonic and output on about 10-12 of hours. Operating an embryogenesis in the period of incubation there is an opportunity to influence the level of productional processes of chickens during the post-embryonic period, average daily gains of live weight at cultivation of broilers increase on average by 5-7%
Smallpox of turkey is a viral, slowly extending disease. It pathogenetically proceeds in a dermatotropic way, skin lesions are characterized primarily by two signs or focal necrotic focus centers or diphtheritic inflammation of mucous membranes, often of the upper respiratory tract. Etiological factor in smallpox are dermatotropic epitheliogenic viruses, the family of Avipoxvirus of Poxviridae. The purpose of this work was studying the features of clinic and the pathomorphological changes at smallpox at turkeys in the context of diagnostics methods and also generalization of treatment-and-prophylactic actions at this pathology. The diseased bird is the main source of infection. In addition, the smallpox virus particles can be spread by people providing care for the birds, indoor air, food, bedding material, excrement. Diagnosis of smallpox takes into account the symptoms; if an autopsy was performed, the result of a pathological pattern as well. Additionally, we can conduct a research of histological sections. Confirmation of diagnosis can be performed by a virological study and the blood serum. In accordance with the pathogenesis of smallpox, there is a classic skin form and diphtheritic. There may be a combination of the above manifestations of smallpox, therefore we can record the mixed form, in some cases, it may be atypical. Pathoanatomical changes come down to defeat a respiratory system of bodies, the upper airways, at the complicated forms there may be noted lesions in the internal organs. Laboratory methods include identification of the virus in the pathological material, as well as additional histological and virological studies using chicken embryos and bioassays. Treatment is difficult and not always effective. The main preventive measure against smallpox in turkey is vaccination, basic applied biologics are: Avivac-pox" strain "K", "Ospovat, Vectorman FP-MG". Prevention of smallpox includes the implementation of general veterinary and sanitary rules in conjunction with the mandatory special prevention. When planning measures to prevent the spread of smallpox, conditions are created to eliminate pathways of transmission of the pathogen – disinfection, disinsection and deratization, as well as vaccination of all susceptible livestock
The article represents the results of studying the spatial-dynamic factors and revealing the regularities of the global spread of Lumpy skin disease in cattle. The developed risk analysis and epizootological forecast provides the keeping up with a multi-year trend for the growth of epizootic tension in this disease for the period up to 2030. The highest probability of disease registration from 0.6 to 1.0 is predicted for the tropical agroecosystems of the African continent (enzootic zone) in 2018-2030. There is a real risk of disease in neighboring countries of Eurasia with the probability is less than 0.4. In the Russian Federation, outbreaks can occur in all federal districts of the country, but the highest probability of its occurrence is possible in agroecosystems of the subtropics of the North Caucasus and Southern Federal Districts of the country
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
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
Coloring the plumage of chickens is a complex genetically determined sign. The study of the interactions of the main genes of chicken pigmentation was started by A.S. Serebrovsky. The most complete information on the genes of coloring plumage of chickens and down of chickens is given by Z.M. Kogan, indicating the clutch groups and the arrangement of these genes on the chromosome map. In the 1990s, the interaction of color genes, pen pattern and modifier genes affecting the intensity of the main color and pattern of the pen was described in detail. It was found that in pigs the pigmentation is regulated by the MC1-R melanocortin receptor associated with the locus E. Due to molecular studies, loci of dominant white color (I), recessive white color (c / c), striped pen pattern (B) adherent to the floor , and spotted spot locus (mo). The final phenotype depends not only on individual genes, but also on their interactions and the genetic environment as a whole. The same genes can produce different patterns and shades of the main plumage, and different genes determine the same phenotypes. Despite the fact that there was significant progress in determining the molecular causes of the appearance of a particular type of color in chickens, much remains to be learned
