Abstract
The article deals with the effects of nitrogen nutrition on the production of spring rape varieties and row spacing on the linear growth of plants aimed at improving the rice yield. The experimental studies were carried out on the fields of the Federal State Unitary Enterprise “Harada” in the Oktyabrsk District of the Republic of Kalmykia located in the zone of the Sarpin irrigation system. The resource-saving technologies that can increase the yield without irrigation using residual moisture reserves are of great importance. Intermediate crops can accelerate the soil cultivation on rice fields and increase the rice yield. When spring rape is sown, the soil acquires an increased ability to restore the structure of the soil layer. The green mass is digestible and contains a small amount of fiber. With a high level of moisture, it can give several yields of green mass. With intensive growth of rapeseed after mowing crops, it can be used for grazing. Over the years of research, the yield of green mass varied from 14.8 to 22.9 t/ha. It was revealed that for Vizit variety, an increase in the row spacing from 15 to 30 cm does not reduce the yield of green mass, and with an increase from 30 to 60 cm, the yield decreases by 22 … 28%. For Ratnik variety, the best row spacing was 45 cm. An increase or decrease in row spacing reduces the green mass yield by 8 … 12%. The influence of nitrogen nutrition and sowing density on the production process and green mass yield was identified.

Abstract
Correlation of quality of colostrum in dairy and dual-purpose cow breeds and duration of calving cycle periods has been examined. It was established that the highest content of immunoglobulins in colostrum of cows of the Bestuzhev and the Russian Black Pied breeds was noticed with the duration of a service period of up to 60 days, in colostrum of cows of the Holstein and the Ayrshire breeds – 61-80 days. Furthermore, the content of immunoglobulins raises by 26.0% for the Bestuzhev breed, by 27.7% for the Russian Black Pied breed, by 16.7% for the Holstein breed and by 17.5% for the Ayrshire breed with the extension of gestation period from 270 to 290 days. A trend towards reduction of content of immunoglobulins with the extension of lactation period was noted. The highest content of immunoglobulins was in colostrum of cows of the Bestuzhev breed (102.7 g/l) that excelled their herdmates of the Russian Black Pied breed by 51.5%, of the Holstein breed - by 71.7% and of the Ayrshire breed – by 11.9%. Colostrum of cows without dry period was considered unsuitable for feeding calves, regardless of the breed. The highest content of immunoglobulins in the first yield colostrum was typical of cows of the Russian Black Pied, the Holstein and the Ayrshire breeds with the duration of the dry period of 61-70 days, and for the Bestuzhev breed – with the duration of the dry period of 51-60 days.

Abstract
In modern conditions, the improvement of technological methods in bee-farming significantly affects the production of bee-farming products. The concordance of technological operations of keeping bee families to climatic conditions of a particular region largely determines the production activity effectiveness of a beekeeper. Temperature differences in winter negatively affect the condition of bee families; humidity and excess condensate are accumulated in hives. The use of “zeolite” desiccant in winter allows improving microclimate inside the hive, contributing to more intensive development of bee families in spring and increasing marketable honey productivity due to its unique highly porous structure. Field studies were conducted during 2014-2016. Four groups of bee families were selected using the pair-analogue method in the course of the research: control group (without desiccant) and ex-perimental groups № 1, № 2, № 3 where in winter, the desiccant was placed at the hive bottom in the amount of 100, 150, 200 g, respectively.

Published: January 2020

Abstract
The newborn calves have a number of physiological features that make them especially vulnerable to infectious diseases. Therefore, along with serums and vaccines that provide specific immunity, immunomodulators are used to correct the immunological status of animals after giving colostrum. The article presents the data on the study of indices of nonspecific resistance of calves after birth and their correction with interferon alfa-2b. It was found that in the group of calves that were introduced interferon, there was an increase in the number of lymphocytes (T lymphocytes - by 11.9% (P <0.05), B lymphocytes - by 28.2% (P <0.03), and also the phagocytic activity of leukocytes - by 13.5 % (P <0.00001), with a decrease in leukocytes by 12.6% (P <0.01), which was the evidence of the corrective effect of the preparation on the cell-mediated immunity. An increase in serum bactericidal activity (SBA) by 19.4 % (P <0.00001), serum lysozyme activity (SLA) - by 46.3% (P <0.00001), serum complementary activity (SCA) - by 35.3% (P <0.04), as well as immune globulins (γ- globulins - by 1.62 times (P <0.002), total immunoglobulins - by 21.8% (P <0.0005), immunoglobulins G - 23.0 % (P <0.04), which characterized the enhancement of nonspecific humoral immunity, was registered in the blood of calves of the experimental group compared to the control one. Thus, the application of the interferon contributed to the activation of nonspecific humoral and cell-mediated immunity of the newborn calves.

Abstract
To improve the nutritional value and digestibility in recipes of all-mashes the following feed additive was introduced: a paste of green mass of amaranth in doses of 10.0 and 15.0% and complex “Enzymesporin” - “Fungistat-GIC” (EF) at doses of 1.0 and 2.0 g/kg of all-mash, respectively. The studies of the effectiveness of complete granular all-mash were carried out on the livestock of young rabbits of the Soviet chinchilla breed at the age of 45 days, selected on the principle of groups - analogues and divided into 3 groups. The study was conducted in vivarium conditions of the VSAU in 2018. The control group of rabbits received a basic ration consisting of fodder PZK-92-60-18, rabbits of the experimental group received feed with the addition of the paste of green mass of amaranth and “Enzymesporin” - “Fungistat-GIC” (EF). Meat quality assessment was carried out at the age of 105 days after control slaughter in the amount of 3 heads from each group. It is established that rabbits of experimental groups digest nutrients of al-mashes better in comparison with control peers that further had positive influence on indicators of their meat productivity. The introduction of feed additives used in the al-mashes allowed increasing its digestibility by 8.5-10.0%, and also contributed to a higher transformation of feed nutrients into the protein component of muscle tissue.

Abstract
We examined the efficiency of probiotic “Sporotermin” and “A2” for increasing the productivity and physiological status of the rabbits. The studies were conducted on a crossbreed population of rabbits (Soviet chinchilla and New Zealand red) at the age of 45 days, divided into control and experimental groups of 15 heads in each by the method of pairs-analogues in the vivarium of the faculty of veterinary medicine and animal husbandry technology of the Voronezh State University in 2017-2018. Rabbits of group 1 (control) received all-mash without additives, rabbits of group 2 and 3 additionally received probiotic preparation “Sporotermin” in a dosage of 1.0 g/kg of feed (rabbits of group 2) and “A2” in a dosage of 0.6 g/kg of feed (rabbits of group 3). Upon reaching the age of 120 days, the live weight of all groups exceeded 3.0 kg, while rabbits of the 2nd group had an advantage over individuals of the 1st and 3rd groups by 295.0 g (9.10 %) and 115.0 g (3.36%). At the end of the experiment (120 days) in animals of the 2nd and 3rd groups there was a significant increase in the amount of total blood serum protein by 5.59 and 3.92% (P>0,95), respectively, compared with the control, as well as an increase in the amount of hemoglobin. In the experimental groups carcass yield made up 60.38 % and 56.88% (P>0,99), while in the control amounted to 55.56 % Thus, the preparation “Sporotermin” is a promising product from a number of probiotics used in animal nutrition and allows improving the productivity and meat quality of rabbits.

Published: January 2020

Abstract
With the strong development of soil erosion, land fertility decreases, crops are damaged, ravines turn agricultural land into uncomfortable land and make field cultivation difficult, siltation of rivers and reservoirs occurs. In this regard, issues of land protection from erosion are relevant. The article discusses the issues of identifying potentially erosion-hazardous lands using the method of relief plasters, previously used in landscape science. This method allows to facilitate the identification of destructive processes at an early stage of development and to prevent them in advance. The location of the zones identified by this method (morphoisographs), and their dynamics, characterizes the changes associated with ecological-landscape measures, for example, planting of forest belts, afforestation of ravines and, accordingly, redistribution of surface and underground waters. A morphoisograph, as the line most sensitive to negative phenomena (changes in the chemical, biological, and mechanical composition of soils, soil erosion, etc.) can become the main criterion for identifying potentially unstable zones. The authors highlighted agricultural land that is potentially unstable to erosion. The introduction of a morphoisograph into ecological landscape design expands the possibilities of detailed accounting for the development of erosion processes in the future.

Published: January 2020

Abstract
During lactation, a significant amount of nutrients is excreted from the body of cows with milk. In addition, their significant costs for the functioning of the mammary gland. The quality of feed rations also has an effect on the taste and technological qualities of milk. The aim of this work was to identify and establish the degree of influence of some external, paratypical factors on the level of milk productivity of cows. The material for the study was a dairy herd of cows with milk production indices of at least three completed lactations. These data allow concluding that feeding cows is not enough both in terms of total energy nutrition and individual nutrients. In close connection with the level of feeding of rearing animals and young cows is their body weight as an indicator of the growth and development of animals.

Published: January 2020

Abstract
In order to improve the immune response to salmonellosis in vaccinated calves, we tried applying the 0.01 % solution of miramistin combined with an inactive emulsified vaccine. Timogen was used as the control medicine because it is well known for its immunomodulatory properties regulating the cellular and the humoral immunity. The research was carried out at a large farm in Lipetskaya oblast that has a high salmonellosis incidence rate among calves. This research uses the epizootological, the clinical, the immunological, the hematological, and the molecular genetic methods. We ascertained that the application of the 0.01% solution of miramistin and timogen to calves for the purposes of salmonellosis etioprophylaxis combined with an inactive emulsified vaccine promoted high cellular immunity. These medicines increased the levels of lymphocytes and their T-cells by 7.0% and 12.5%; their B-populations by 2.8% and 5.1%, the neutrophil phagocytic activity by 5.9% and 13.0%, the phagocytic number by 7.2% and 15.0%, the phagocytic index by 7.0% and 18.0% respectively. The improvement of humoral immunity factors comprised 3.0% and 7.2% for blood serum bactericidal activity; 3.0% н 4.3% for blood serum lysozyme activity; and 1.7% and 2.0% for blood serum complement activity. The O-agglutinins and H-agglutinins to salmonella antigen increased by 1.5 and 2 times respectively, and the disease rate decreased by 40.0% and 80.0%, while promoting the survival rate by 80.0% and 87.0% respectively, which shows that the 0.01% solution of miramistin has better immunomodulatory properties.

Abstract
The article proposes the results of investigations on agroecological assessment of oil flax varieties depending on the sowing time in the southern part of the Nonchernozem belt of Russia. The experiments took place at the agrotechnological experimental station of Ryazan State Agrotechnological University Named after P.A. Kostychev on gray forest soil typical of the region. It should be noted that the introduction of new varieties into the zone requires a more detailed study of the technology of their cultivation, including the determination of the optimal seeding rate and sowing date for specific weather conditions. The objects of investigations were domestic varieties of flax: Istok, VNIIMK 620, Sunlin and LM 98. Sowing was carried out in two terms - the third decade of April and the first decade of May. According to the results of experiments, it can be concluded that the yield was formed due to the density of planting, largely due to better survival in the second term of sowing. Despite significantly lower yield parameters of the second crop, such as the number of bolls per plant, the mass of 1,000 seeds, the number of seeds per boll, the yield of Sunlin and LM-98 varieties was higher than in the first term of sowing. On average, the maximum productivity was shown by Istok variety when the first sowing period (21.2 dt/ha) and Sunlin variety when the second period of sowing (20.6 dt/ha). During the years of studying varieties, flax oil content was 36.3-46.3 %. There was a decrease in this parameter in all experimental varieties by 1-3.5 % in the second period of sowing.

Published: January 2020

Abstract
One of the main line of the development of food industry is replacing a part of the recipe of classic sauces; however, this problem cannot be solved without using vegetable stock. In particular, we propose using pumpkin, a native plant of the Volga region. The use of the lipidic carotenoid pumpkin extract allows solving a few problems of the food chemistry; however, this study only deals with partial replacement of the raw stock for production of sauces for this product. The preparation of sauces with addition of the lipidic carotenoid pumpkin extract does not require replacing the equipment and process lines, therefore this line of research may be considered a promising one.

Abstract
The results of studies on the influence of the genotype of red-mottled cows of Holstein breed on the chemical composition and technological properties of milk are presented. In a herd of cows of the red-mottled breed of the cattle of “Roschinskoye”, for the assessment of the chemical composition and technological properties of milk depending on the genotype of the animals by the method of pairs-analogs, 3 groups of full-aged cows were formed: 1/2, 5/8 and 3/4-blood on KPG. The selected milk on the farm was analyzed in the laboratory of Voronezh State Agricultural University named after the Emperor Peter the Great. For a more complete picture of the qualitative indicators of the milk obtained from the full-aged cows with blood 1/2, 5/8 and 3/4 KPG, butter was also produced. As a result of the production of a trial batch of dairy products, the technological properties of the milk during processing, as well as oil and physical, chemical and organoleptic characteristics of the finished product, were determined. On the basis of the conducted research, the recommendations on improvement of the red-mottled dairy breed of the cattle were given.
