Abstract
Experimental larval rearing of the Japanese sea cucumber in a mini plant in Severnaya bay (Slavyansky bay, Sea of Japan) was carried out. The experiment did not reveal any relevant difference in time or speed of reaching different larval development stages or survival rate of the sea cucumber either with the diet supplemented with pigmented yeast Rhodotorula benthica or when fed with the Chaetoceros muelleri and Dunaliella salina phytoplankton. In the lack of the traditional phytoplankton-based fodder, it appears relevant and feasible for the aquaculture enterprises to use such fodder replacement options as Rhodotorula benthica marine pigmented yeast, a non-pathological species with low production cost that does not require any sophisticated cultivation techniques, easy to use and generally yielding a highly predictable production result.
Questions of conservation of wildlife of the Arctic zone

Published: September 2020

Abstract
The article is devoted to the urgent problem of maintaining the integrity of ecological systems of the weakest link in the planetary biosphere - the Arctic zone of the Republic of Sakha (Yakutia), which occupies more than half of its entire territory, located mainly in the tundra and forest-tundra geographical zones. The factors causing the high vulnerability and difficult recoverability of ecosystems and the requirements of these factors in order to preserve them are given. It is argued that the traditional nature management of the indigenous population of the Arctic zone is not an antagonist of wildlife. At the same time, the inclusion of products in commodity-money relations in a market economy can lead to the depletion of biological resources. It is argued that the most widespread and deepest negative consequences of the environment are caused by industrial production. The most destructive, dirty mining industry is expanding in the Arctic zone. Industrial companies, enterprises do not engage in environmental protection, arguing that environmental protection does not give dividends, increases the cost of their products. The state conducts the wrong policy in relation to extractive companies, enterprises, refusing to control and regulate functions. Taking advantage of the fact that the subsoil is in federal ownership, companies have no obligations to the republic, territory, nature, they do not even allow control. The article provides legislative, administrative and economic measures that must be taken to preserve the integrity of ecosystems and wildlife resources. article the main questions connected with development of domestic agricultural producers are considered, in particular, the main directions of development are allocated. In article it is told about trends of development of agriculture in the conditions of the international sanctions and also development of the technological direction in means of UAVs, robots, innovative machines and the equipment. Also the main issues of development of meat production as one of the most priority directions of development of agriculture are considered in article.

Abstract
The forest park landscape is a cultural “anthropogenic landscape”, which assumes optimal and rational use of natural resources in order to create favorable conditions for mass recreation in the natural forest environment. The impact of recreation on the forest park areas, as well as on the territory of all protected areas, has a number of regularities. In cases where the number of visitors significantly above the acceptable level, and resistance is relatively low, the anthropogenic impact is not only visible, but can be damaging to the individual components of the environment, and sometimes to the whole complex in general. Such an impact causes a response from the natural environment. The analysis of the state of the Medvedkovsky forest park was carried out to recognize the main determinants of the negative repercussions on this territory. For this purpose, the flora and fauna, the road and path network, the degree of recreational digression of the territory, as well as the noise impact exerted on it due to its proximity to the MKAD (Moscow ring road) were taken in account.

Abstract
The article presents the production technology and the results of using a symbiotic preparation based on the E. coli strain VL-613 as a lysine producer in poultry farming. In the practice of feeding productive animals and birds, the problem of lysine deficiency is solved by introducing components of animal origin into the type of diet, as well as synthetic or microbial lysine. A symbiotic preparation (trade name “Proliser”) was produced by periodic controlled deep cultivation of E. coli VL-613 strain in a nutrient medium, based on the Hottinger’s overcook, the concentrated bacterial mass was mixed with a protective medium and cool dehumidificated for long-term retention of biological properties. The E. coli VL-613 strain is able to multiply in the digestive tract of farm animals and birds, can synthesize lysine up to 6.0 μg/cm3, and is not pathogenic to animals and birds. The symbiotic preparation was treated to Cobb-500, Avian-48 and Smena-7 cross broiler chickens by unsoldering or applying to feed pellets. The use of the “Proliser” preparation allowed to increase viability, average daily weight gain and the yield of category 1 meat in broiler chickens, as well as reduce the yield of low-grade meat. The results of tests on a large number of poultry population of poultry farms in the Moscow region showed, that the use of the “Proliser” symbiotic preparation will allow to completely replace synthetic lysine in feed diets for broilers of highly productive crosses.

Abstract
Main patterns of interrelationship between parameters of vacuum freeze-drying and the preservation of antioxidants in final product at different primary temperatures were determined in this article. Jackfruit, melon, and banana were frozen in pieces. The process of freeze-drying of the fruit raw material was at the primary temperature (from minus 10 to minus 30 °C) at an appropriate vacuum. At the secondary drying, the temperature was always the same, equal to 38-40 °C. Freeze-dried fruits were added at the stage of preparation of the mixes of yogurts. The total integral antioxidant activity was measured in the finished products by coulometric titration. The research demonstrated that vacuum freeze-drying at increasingly lower primary drying temperatures leads to a preservation the more content of antioxidants. It has been determined that the addition into yoghurt freeze-dried fruit powder leads to rise total antioxidant activity by 11.3-14.7 %. Our data have shown that there is the possibility of choosing, in agreement with potential consumers, the desired quality of the finished product and this can effect on total cost of process.

Published: September 2020

Abstract
The article is devoted to the problem of balanced nutrition in modern living conditions. The lack of vitamins, micro and macro elements negatively affects human health. Currently, much attention is paid to the problem of nutrition – new enriched products appear on the shelves, and consumers are increasingly paying attention to their composition and nutritional value. The creation of meat products intended for the prevention and treatment of diseases is an actual direction in the food industry, which has extremely important practical and social significance. The purpose of this work is to increase the nutritional value of sausages by using secondary products of regional plant materials – powdered mustard cake. By steaming the cake, the allyl mustard oil is removed, which gives a specific smell and a burning taste. The resulting additive with a residual essential oil content of not more than 0.05-0.1% is considered suitable for use in the technology of enriched meat products. As a result of the studies, the addition of processed mustard cake in the amount of 6-8 kg per 100 kg of raw meat to cooked and semi-smoked sausages positively affected the functional and technological parameters of the minced systems, as well as the main quality indicators developed in the framework of the experimental prototypes. The use of the indicated plant component in the formulations made it possible to increase the yield of the finished product, as well as to increase the stability of the minced system: in cooked sausages by 6%, in semi-smoked sausages – by 1%. A study of the biological value of protein showed an increase in this indicator in the studied product samples: in cooked sausages, this indicator increased by 1.9%, and in half-cooked sausages by 5.7%. In the test samples, essential amino acids are in more balanced proportions due to the high biological value of the protein.

Published: September 2020

Abstract
Current development trends of the global and national economies require a search for effective approaches to expand participation of small agribusiness entities in providing population with domestic livestock products. The article focuses on state support programs for family livestock farms and novice farmers in the framework of the national project “Creating a system of support for farmers and the development of rural cooperation.” Development trends of the meat and dairy cattle breeding industry in the Rostov region—a large agricultural region of Russia - have been noted. A deep comprehensive economic analysis of the composition and structure of financing state programs to support small regional agribusiness entities in the livestock industry was conducted, and the ways for its further development have been determined. Regional authorities have been established to be able to identify and significantly expand priority areas for the development of the meat and dairy cattle breeding industry, while consolidating state support measures regarding the distribution of grants to family farms and novice farmers. The need to develop industrial and economic relations of small business in the livestock sector of the region due to the system of consumer cooperation has been justified. A considerable potential for cooperation in the dairy industry has been noted. The methodology of the research on the problem was based on a system of general scientific and local methods and techniques. The information-analytical basis of the study was the data of the Ministry of Agriculture and Food of the Rostov Region and data of the Federal State Statistics Service of the Russian Federation.
Improving the technology of crushing root crops
Authors: Smirnov N A , Smirnov R A 
Published: September 2020

Abstract
The relevance of the article is due to the fact that the efficiency of production of livestock products largely depends on the quality of the feed base, the preparation of which requires special attention. Today, farmers use various types of feed: coarse, juicy, concentrated, fermented. Due to some advantages (high yield, easy digestibility, good eating, beneficial effect on the physiological state of animals), a valuable type of juicy food is root crops. When processing root crops, including preparation for feeding, it is mandatory to grind them, which is the main focus of this article. According to zootechnical requirements, root crops are crushed to particles of 10 … 15 mm for cattle, 5…10 mm for pigs and 4…5 mm for poultry. Analysis of existing shredders today has shown that they are characterized by high energy consumption, complexity of construction, low productivity. Crushed in most of these machines, the feed does not meet the zootechnical requirements, being a porridge-like state, which leads to the loss of juice and nutrients. Therefore, the proposed method of preparation in the article, in our opinion, will allow you to get food that meets the zootechnical requirements for all groups of animals with minimal energy consumption.

Published: September 2020

Abstract
Over the past several decades, work has been carried out in the Lower Volga region to improve the assortment of pears using classical and analytical selection methods. Until 2016, the main breeding work was carried out in the Lower Volga Research Institute of Agriculture after the reorganization in the Federal Research Center for Agroecology of the Russian Academy of Sciences. The selection process was based on the methods of stepwise intervarietal hybridization. High-winter-hardy, but with low quality fruits, varieties of local selection and high-quality, but not sufficiently stable, varieties of western selection were used as parent forms. As a result, varieties and hybrids were obtained that have high fruit qualities and increased resistance to abiotic and biotic stress factors of various periods of consumption. Currently, three varieties are zoned in 8 regions, a number of varieties and hybrids are undergoing preliminary and state tests, and can be used both in production and further breeding as donors and sources of economically valuable traits.

Abstract
The article presents chemical compositions of dairy products and milk from dairy cattle kept under different technological conditions, i.e. stable keeping at AE LLC Donskoye, Kalachevsky District, Volgograd Region and stall-camp keeping at JSC Kirov Farm, Staropoltavsky District, Volgograd Region. To determine chemical compositions, methods of inductively coupled plasma mass spectrometry (ICP-MS) and inductively coupled plasma atomic emission spectrometry (ICP-AES) were applied. There was used an Elan 9000 quadrupole mass spectrometer (Perkin Elmer, USA) and an Optima 2000 DV atomic emission spectrometer (Perkin Elmer, USA). The article also provides a comparative description of macro- and microelement compositions of samples (milk, sour cream, cream, whey, cottage cheese, and butter) and concentrations of heavy metals. The obtained results allowed a conclusion that stall keeping is preferable for obtaining high-quality dairy raw material because ruminants’ microflora in forestomachs cannot quickly adapt to summer pasture rations after winter stall keeping.

Abstract
The article discusses the results of screening strains of probiotic bacteria by their ability to metabolize cholesterol during development on different nutrient media. Cholesterol content was determined by the method of Zlatkis-Zack. The results on the possibility of creating starter cultures from proven strains capable of lowering cholesterol in vitro and taking into account technological properties were presented. Four starter cultures were created, which included microorganisms belonging to two genera: Lactobacillus, Bifidobacterium (strains were deposited). The created starter cultures showed a higher activity for cholesterol reduction than each strain separately. To confirm the revealed effect, studies of starter cultures were carried out in vivo on the SHK line both sexes white mice. The research results showed that when using the created starter cultures in the nutrition of white mice, against a background of elevated cholesterol, there was a decrease in the concentration of total cholesterol in the animal blood by 38.5 % maximum, compared with mice fed with high cholesterol but without starter cultures. The obtained research results allow us to draw to a conclusion about the possibility of participation of the created starter cultures in cholesterol metabolism and recommend them for use in biotechnology of functional foods.
Optimizing broiler diets using protein supplement
Authors: Volkova G S , Kuksova E V , Serba E M 
Published: September 2020

Abstract
The results of the studies showed that the inclusion of compound feed protein supplement “Biobardin” in the amount of 3-5% had a positive effect on the main indicators of productivity (preservation and increase in live weight) of broiler chickens. The feed obtained using Biobardin was characterized by a higher content of protein, organic acids, bacteriocins, and also contained the biomass of lactic acid and propionic acid bacteria. It was established that the broiler chickens absorbed enriched mixed feed more efficiently than the chickens, which consumed similar mixed feed without the studied additives. The broiler chickens from the experimental groups were significantly superior to their peers from the control group: the chickens not only grow better, use feed more economically, but also effectively transform the nutrients of the diet into body weight gain. On the basis of the results of experimental feedings, near-complete preservation of young birds, rapid development and weight gain, good physical condition, absence of diseases, good food intake were noted. The introduction of 5% protein feed additive “Biobardin” into the broilers’ diet can be a real competitor to the traditional source - fish flour or alternatively be used in industrial poultry farming along with it.
