The article summarizes the results of long-term cultivation of east-asian plants in the arboretum of the Gornotayezhnaya Station of the FEB RAS. For the most resistant and decorative species we have indicated: degree of winter resistance, shoot formation and perspective group. Regeneration of the vegetative mass in introduced trees and shrubs after severe damage by low temperatures depends on the spawning capacity of plants. In each species, the degree of shoot formation is its biological feature and can vary greatly in different plant species. The most east-asian species have a high or medium degree of shoot formation, good indicators of winter resistance and of generative development (bloom, fruiting). The tested east-asian species of plants are characterized by high adaptive potential, which makes it possible to recommend them to a wide culture in the southern Primorye. The purpose of the study is to evaluate the introduction stability of east-asian plants in the conditions of the southern Primorye. Тhe method of the integral assessment of the viability and perspective of introduction on the basis of visual observations, developed in the department of dendrology of the GBS, P.I. Lapin and S.V. Sidneva, was used to determine the perspective groups of the introduced species

We have performed a comparative estimation of three coccidiostats when experimental eimeriosis of chickens, infected with a coccidia field isolate from poultry production sites. Chickens performance treated with robenza, chicocin and monenza was almost the same. The anti-coccidiosis index was also the same in all three groups, not exceeding 160, which indicates the low sensitivity of coccidiosis agent to all studied drugs. An ionophore antibiotic (chicocin), a synthetic anti-coccidia drug (robenz) and a complex (monenza) consisting of an ionophore antibiotic and a synthetic anti-coccidia drug can be used in this poultry complex for the prevention of coccidiosis for a short time. But there is a need for constant monitoring and selection of new combinations, as partial resistance of coccidia to drugs can be transmitted genetically and will only increase over time, making coccidiostats ineffective
In the experiment, the effect of the use of an intelligent spreader on increasing the efficiency of nitrogen fertilizers used to feed winter wheat in ordinary chernozem was studied. The studies were carried out in the production conditions of land use by AO SHP Kolos in the Kochubeyevsky district. In this article, we examined the effect of a sprayer (Amazone UG 3000 Nova) and an intelligent mineral fertilizer spreader (Amazon ZA - TS - 4200) using touch sensors to determine the NDVI development index on the efficiency of nitrogen fertilizing winter wheat. Based on the experiments, it was found that, on average, over the two years of the study, the largest increase in the yield of winter wheat grains was noted in the variant with the introduction of ammonia nitrate in the first and second fertilizers using the intelligent fertilizer spreader Amazon ZA - TS - 4200 according to the NDVI - 6.53 t / ha. The highest structural indices of winter wheat grain yield were also noted in the variant with the introduction of ammonium nitrate in the first and second fertilizers using the Amazon ZA - TS - 4200 intelligent fertilizer spreader according to the NDVI index. So, the height of plants increased by 16.3 cm, the number of productive stems per 1 m2 by 37 pcs. The number of grains in the ear - by 5 pcs., The weight of 1000 grains - 0.8 g. According to the results of the experiments, it was established that in the conditions of land use by JSC "Agricultural Enterprise" Kolos "of the Kochubeyevsky District of the Stavropol Territory when planning the harvest of winter wheat - 6.5 tons / ha, it is advisable to use in the first and second top dressing of ammonium nitrate with a dose of 150 kg / ha, using the Amazon ZA - TS - 4200 intelligent fertilizer spreader according to the NDVI index
The article is devoted to the current problem of differential diagnosis of diseases of viral etiology in small pets. Viral diseases of dogs and cats are widely distributed among both pedigree and non-pedigree animals. The spread of diseases is facilitated by the increase in the number of small pets, the popularization of pet maintenance, cross-border operations associated with the movement of animals. The importance of express methods in laboratory diagnostics of infectious diseases is considered. Reducing the time of diagnosis contributes to the effectiveness of therapeutic and anti-epizootic measures. The place of infectious hepatitis of carnivores in the structure of morbidity of dogs is analyzed. The article describes the research in determining the optimal systems for the cultivation and subsequent isolation of the infectious canine hepatitis virus in high titers. If viral biomass needs to be increased, the choice of a cultivation system for maximum harvest is of paramount importance. The authors propose a method of obtaining and purification of viral antigens to use them for preparation of diagnostic kits. The release of the isolated fraction of ballast substances, which provides rapid response and strong binding to specific immunoglobulins is essential for the preparation of antigenic drugs. It is important to obtain antigens with a high degree of purification to get reliable results in the formulation of serological reactions

A significant decrease in yields of field crops due to lack of moisture enhances the role of adaptive breeding. The development of varieties that combine high productivity and quality and resistance to biotic and abiotic stresses is complicated by a negative correlation between high yield and resistance to adverse conditions. Selection of effective methods for assessing the potential of productivity and resistance to stress factors allows creating varieties that provide stable high yields. We had estimated six varieties of common mustard for 10 years in contrasting weather conditions in the zone of insufficient and unstable moisture of the Azov district in the Rostov region. The necessity of taking into account the indicators of the HTC, the index of the environment and its value when conducting an objective analysis of weather conditions is revealed. The greatest stress resistance, ecological plasticity and stability of the Nika variety were established by calculating the difference between the minimum and maximum yield per year, calculating the coefficient of linear regression and the value of homeostasis. The varieties Lera, Donskaya 8, Lux bred in conditions of insufficient moisture demonstrated maximum genetic flexibility and drought resistance. The greatest breeding value was determined in varieties Donskaya 8 and Lera. These varieties are recommended to be included in further breeding work. The study of mustard varieties in contrast conditions (HTC from 0.30 to 1.53) marked their broad environmental plasticity, which makes it possible to recommend them for cultivation in different weather conditions regions
