FEATURES OF ANGIOGENESIS OF SQUAMOUS CELL PAPILLOMAS OF DOGS
06.02.00 Veterinary and Husbandry
DescriptionThe 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

EFFICACY OF SUPRANOL AND UTEROTON IN PREVENTION OF ACUTE POSTPARTUM ENDOMETRITIS IN COWS
06.02.00 Veterinary and Husbandry
DescriptionThe 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

Description
As a result of the study of the influence of different forms, doses and timing of mineral fertilizers on the content of heavy metals in soils of different areas of the agricultural landscape, in the conditions of the relief of the Timashevsky district, there was no excess of MPC values for both gross and mobile forms in the arable and subsurface horizons of ordinary black soil. It is noted that mineral fertilizers do not have a negative impact on the agroecological indicators of ordinary black soil

ADVANCED TECHNOLOGIES AND MEANS OF CULTIVATION
05.20.00 Processes and machines of agroengineering systems
DescriptionDue to the disconnectedness of production processes, prevention of soil degradation and plant diseases, as well as the difficult establishment of functional dependencies between the parameters of the working bodies and the physicomechanical properties of the soil, the richness of foreign technology, there is the problem of creating innovative structural and technological solutions for basic soil tillage including for the purpose of import substitution. To solve it, KubGAU has developed: “Multifunctional plow” (patent of the Russian Federation No. 2618342); “Plow with rotary bar” (utility model RF patent No. 184196); “Multifunctional plow with a rotary bruce” (positive decision on the patent application of the Russian Federation). Formal models, schemes and descriptions are given

NEED OF DAIRY CATTLE IN ESSENTIAL AMINO ACIDS
06.02.00 Veterinary and Husbandry
DescriptionThe 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
