The article reflects information characterizing the significance of mastitis and endometritis in the indicator of premature disposal of cows from herds of large farms in the western regions of the Krasnodar region: an average of 30% of the total culling of cows. The effectiveness of veterinary measures in Pravoberezhny JSC of the Temryuk district for mastitis and endometritis in cows was assessed: 81-95%; fertilization index value ‒ 1.8; the duration of the service period exceeds the requirements by 20 days. The studies the nature of the influence of the drugs called Sepranol and Uteroton on the calving process and the occurrence of postpartum complications in cows from the herd, which was formed with violation of breeding principles. The use of the drugs Uteroton and Sepranol contributed to a 50% decrease in the calving index in calving cows by 50% compared with the results of the combined use of estrophan and oxytocin. The use of Uteroton reduced the damage from the lack of milk by 87880 rubles, and the use of Sepranol - by 171164 rubles. We have given practical recommendation on the use of Uteroton and Sepranol for veterinary effects on the body of cows in the early postpartum period in order to reduce the occurrence of complications
The article presents a factorial model for determining the needs of lactating cows in essential amino acids. The algorithm of the model uses fragments from the NRC – 2001 models [39], CNCPS – 200 [60], and research materials published in the world literature. Instead of the transformation coefficients of the metabolizable lysine and methionine for milk production equal to 0.85 and 1.00, respectively, by the CNCPS, the coefficients 0.68 and 0.66 were used according to Doepel et al., 2004 [49] and the authors' own data [69]. Norms obtained using this model in lysine and methionine in milk production and maintenance in percentage of metabolizable protein (MP) were 7.28 and 2.4%, which is identical to the NRC – 2001 standards, equal to 7.2 and 2.4 % respectively, obtained by dose – response method based on dozens of experiments. The norm of histidine was 3.5%, which closely corresponds to the indicator of 2.4 and 2.7 % MP [74], obtained by the incremental addition method. This indicates that the presented model is distinguished by sufficiently high accuracy and is comparable with the models developed by the dose – response method. However, the determination of the need of cows for amino acids in this model is much less expensive than the dose – response method. The need for the absolute amount of metabolizable essential amino acids (MEAA) for milk production (35 kg/d, yield milk protein 1103 gytt6) and maintenance cow - 600 kg, g/d: lysine - 178, methionine - 59, arginine - 119, histidine - 60, isoleucine - 138, leucine - 248, phenylalanine - 152, threonine - 134, tryptophan - 38, valine - 174; the need for only milk production, g/d: 130; 42; 81; 42; 95; 175; 98; 74; 25; 112; the need for only maintenance, g/d: 50; 16; 38; 20; 43; 73; 54; 60; 14; 64; the need for 1 kg of milk (31.5 g of protein) g/kg: 3.7; 1.2; 2.3; 1.2; 2.7; 5.0; 2.8; 2.1; 0.7; 3.2; need to maintain, g / kg 0.75: 0.41; 0.14; 0.31; 0.16; 0.35; 0.60; 0.44; 0.50; 0.11; 0.53. In addition, the article presents the norms of amino acids per 1 kg of dry matter (DM) ration. However, the proposed standards need a comprehensive assessment in the research and practice of dairy farming. Research is needed to improve the models and predict the MEAA in the rations in the following areas: studying the metabolism of amino acids in the body of cows and determining their costs for maintaining the digestive tract, tissues and organs, refining, on this basis, the utilization of amino acids for milk protein production and maintenance; the development of ideal amino-acid profile of low-protein diets, both due to the adjustment of natural ingredients, and through the use of amino acid preparations that are protected from disintegration in the rumen
The article deals with angiogenesis of squamous papillomas of dogs, which is a process of formation of blood vessels, providing neovascularization of tumors with their progression. The differentiation of papillomas depending on morphological and histological features was carried out, progressive and hyperkeratinized types were identified, which determine the stage of development and transition from one to another in the process of tumor growth. It is noted that with the progression of papillomas, the area of the constituent elements of the tumor increases, both due to the stroma and due to the parenchyma, but the stromal-parenchymal ratio changes in the direction of increasing the parenchymal component. Analysis of angiogenesis showed heterogeneity of the isolated vessels, both within the stromal component of papillomas, and depending on the type of tumors. There are three types of vessels – small, medium and large, there is a similar ratio of different types of vessels, regardless of the type of papillomas. Localization of vessels in the stroma depending on belonging to the selected species was studied. The total area of the section of blood vessels with cancer increases, and the ratio of the total area of the section of blood vessels to the area of the stroma is almost at the same level, which determines the dependence of the increase in the stromal component of papillomas from angiogenesis
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 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
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 deals with the problem of producing protein using alternative sources of raw materials, due to the shortage of feed protein and utilization of organic waste. This property makes it possible to return feed protein to farm animals and birds derived from the biomass of insect larvae. The invention relates to agricultural production. The studied problem is relevant for the technology of livestock products (agricultural sciences), which is explained by the global need for proteins and food products. The object of study is several different insects. The article studies the application and significance of some beetles in this field. The study provides a comparative analysis of the Black Linki (Hermetia illucens), House Cricket (Acheta domesticus), Locusts (Locusta migratoria), Flour Castaneum (Tribolium confusum) for a more graphic comparison of the benefit from the application of the above bugs and identify the most unpretentious and best beetle for breeding for food purposes in agricultural production. The work also shows a diagram of the process of development of the larvae of Hermetia illucens. The following research methods were used: observation, collection of scientific and practical information about beetles, study, analysis, processing, systematization of the collected material
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
