Currently, we are constantly improving the recipes of
fish feeds, this reduces the cost of feed per gain, and it
overall decreases cost of fish. We search for
alternative cheaper sources of nutrients. Leftovers of
vegetable oil and oil extraction industry such as oil
cakes and meals have been used as high-protein feed
additives for a long time. This requires a strict
scientific control, precluding the possibility of their
harmful effects on animal health. In this regard, there
was a comparative analysis of the chemical and
amino acid composition traditionally used in
compound feeds for sturgeons of sunflower cake and
feed concentrate from "Sarepta" vegetable raw
materials. During the research it was found that
"Sarepta" is better than sunflower meal considering
protein and essential amino acids content
The gaining of maximum amount of daily young
animals in a greater extent depends on disinfection of
incubation eggs which in complex of veterinarysanitary
arrangements held in poultry factories on
prevention and elimination of poultry infectious
diseases takes an important part. The perspective of
ozone application in industrial poultry breeding is
conditioned with its advantages which it
characterizes in comparison with other chemical
substances. It was settled that ozone has a special
ability to detain the growth of fungi on biological
substrates, also the process of mould appearance on
the surface of eggs’ shell even at 90% of relative
moisture. At substantiation of parameters and
regimes of electro-technological process of egg
storehouse ozonation there were implemented the
experimental researches. The general bacterial
semination of eggs’ shell decreased on 94,1% after
disinfection of incubaion eggs with ozone.
The relative faults of experimental values from
theoretical ones are 7%. In the result of production
trials there were set the parameters of quality of the
worked out electrotechnological process of egg
poultry factory storehouse ozonation: time of
regulation ‒ 8 minutes, dynamic fault ‒ 0,9,
coefficient of overcorrection ‒ 4,5%, generalized
integral mean-square index ‒ 10,6%. Obtained data
testify against the qualitative regulation of allocation
of concentration of ozone in a egg storehouse
The use of resource-saving technologies for cultivation of basic crops does not make sense without the use of microelement fertilizers, biologics and growth regulators. All this fully applies to the technology of cultivation of the main bean culture – pea. In the current market conditions of agrochemical products, microfertilizers are presented in a wide range. Identifying the most effective of them at a price and yield increase is a defining task for agricultural producers. In this connection, the purpose of the research was to study the influence of biologics and growth regulators on the development and productivity of peas with the definition of their most effective them. The studies were conducted in 2014-2016 on the fields of the training and demonstration center on the introduction of resource-saving technologies of the IPCC APK VO "DGAU" in Zernograd, Rostov Region. As the studied drugs there were used Rizotorfin, Extrasol, Vigor Fort, Miwal Agro, Flavobacterin, Biogumat Kubansky, KU-8 Agrofon. As a result of the research, it was established that all the preparations studied showed a positive effect on the development of pea plants grade Angela. The yield gain was 0,34-0,56 t/ha in comparison with the control. The most effective are the following ones: Extrasol with a yield increase of 0,56 t / ha (14,6%) and a profitability level of 232%, Mival Agro – 0,54 t/ha (14,1%) and a profitability level of 192%, Biohumat Kuban – 0,55 t/ha (14,3%) and the level of profitability of 271%. A good level of profitability was noted at KU-8 Agrofon – 224%
Nowadays, fruit trees are subjected to influence of
abiotic stress-factors. The reaction of fruit plants on the
influence of media plays an important role. Experiments
were conducted in two (Northern and Central) fruit
zones of the Krasnodar region since 2013 to 2015, there
was shown the possibility of application of
hydroabsorbents as a stable source of water supply of
fruit trees in specific natural conditions of the South of
Russia in the conditions of field experiment. There were
shown the peculiarities of technological ways of water
supply of fruit trees in specific natural conditions of the
south of Russia. There was determined that the necessity
in watering of a garden’s plots with the use of
hydroabsorbents Ecogel-1 and Ecogel-2 with the
supporting of soil’s moisture in 80% in Northern zone
in the end of May, in central fruit zone in the middle of
May. There was proven that the application of
hydroabsorbents Ecogel-1 and Ecogel-2 guarantees the
stable water supply in limits of 75-80% from NV since
planting in apple-trees of varieties of Renet Simirenko
and Golden Delicious grafted on the stock M9 and
planted on the scheme 4,0 х 1,0 м during three years.

The article presents the comparative assessment of
economic traits of Holstein cows of various ecogenetic
types in the Volgograd region, the Russian
Federation. The study of adaptive ability of Holstein
cattle imported from the United States (245 heads),
Denmark (245 heads), Germany (386 heads), and
Australia (250 heads) has been carried out based on
breeding plant OOO "Donskoye" in Russia since 2006.
The milk producing ability of the animals was studied
during the period of first three lactations. The cows
imported from the United States showed the maximum
productivity. The cows from the USA and Germany
were registered to have the highest fat content in milk.
The mathematical modeling for predicting production
processes revealed that with respect to the milk yield,
the Holsteins of Danish selection were superior to the
cows of American, German, and Australian selections
by the fifth lactation. The high correlation between the
milk yield and the body weight, as well as between the
body weight and the fat content of milk from Holstein
cows of various selections has been established. The
cows of Danish, German, and Australian selections
showed a positive correlation between economic traits
and genetic parameters for the period of three
lactations. The cows from Australia have been proved
to have higher indices of protein composition of milk
(the total nitrogen content, the amount of essential
amino acids). The level of the adaptive ability of the
animals of the same breed but different eco-genetic
types has been found to be stable
The contents of lead in soils are primarily determined by regional factors: the composition of parent rocks, relief, climate, vegetation. In recent years, these factors have increased the anthropogenic source of element. In order to assess its impact, requires knowledge of the natural, i.e., background lead levels, the so-called reference points, which can later be used to monitor changes occurring in the soil. Under background refers to the content of the element in soils at a great distance from the areas of receipt of contamination. Background content of lead in each type of soil depends mainly on composition of parent rocks. The correlation coefficient between the content of lead in parent rocks and soils, with the background contents is equal to 0,86±0,17 at p=0,95. For each soil type there are low variations in lead content due to the composition of parent rocks. Lead concentrations in the soils increased at the expense of its receipt from the atmosphere, irrigation water, drainage during mining, as a result of agricultural use, lead containing chemicals. Comparing the obtained results with existing currently permissible concentrations (APC, MPC) it is necessary to note that the lead content in leached chernozem soil after three rotations of the rotation may not cause any pathological changes or anomalies in the course of biological processes and lead to accumulation in the agricultural plants, and therefore may interfere with biological optimum
The presented research is devoted to the development
of the import-substituting production technology of
the proteins dresser for food from local vegetable
resources, in particular, of lupine. Lupine seeds
contain about 40% of protein rich in all irreplaceable
amino acids. Protein of lupine noticeably differs from
protein of soy in inhibitors content, and namely,
proteases, that does not cause allergic reactions. The
main part of oil composition of oil of lupine is maid
up of linolenic, linoleic and olein acids. Use of lupine
seeds in production of complex raw structure
products will allow to increase the biological value of
a proteins component of a traditional type of raw
materials of phytogenesis and to reduce the available
deficit of protein. It is a will-know fact, that lupine is
added to the recipes of buns, fermented milk and
cottage cheese products, rich crackers and long
cookies. Technologists have recently received a
certain concentrate from lupine seeds of high
biological value, and a pastelike concentrate of lupine
which can be used as a filler in milk, meat, baking
and confectionery industries is being under development. The results of the research show that
seeds of lupine can be considered as one of the
perspective sources of white and competitive
ingredient for developing new recipes and
technologies of different types of multicomponent
food. It is necessary to continue the research on
creation of different types of food with use of lupine
seeds. Thus, the products received from lupine seeds
can be used as raw materials for improvement of
quality of food and as additives for creation of
compoundings of new types of foodstuff
The article considers approaches to conducting longterm
observations, i.e. monitoring of the
immunological characteristics of varieties of winter
wheat. In our work, we use the following grading
system for the immunological characteristics of winter
wheat varieties for resistance to leaf rust in various
stages of ontogeny: evaluation of sustainability in the
seedlings in a phytotron, greenhouse complex;
evaluation sustainability in a field of artificial
infectious background; immunological evaluation
based on phytosanitary monitoring in different
ecological zones. In the initial stages, all the material is
pre-tested in the field of infectious hatchery. We have
performed an evaluation on the intensity of lesion and
the type of plant response to the introduction of the
pathogen. This approach allows getting rid of
susceptible genotypes for a year. To describe the
spread of rust, i.e., increase in population numbers we
have used two types of curves: J-shaped and S-shaped.
The article considers several winter wheat cultivars
differing in susceptibility to leaf rust. It is established,
that the increase in the population of brown rust occurs
in conditions with limited food resources and it is
described by the Ferxulsta function. Monitoring
studies allow developing models taking into account
the promotion of the parasite and its pressure on wheat
cenosis as well as allow building an expert system that
optimizes the protection of plants against leaf rust and
used to study the behavior of genotypes with different
immunological parameters when creating a model
class
This article summarizes results of the research on the
assessment of soil erosion effectiveness of crops and
the rationale of the practical application of phytomeliorative
actions aimed at improving the erosion resistance
of slope lands. We have obtained values of the
resistance of soils to erosion under agricultural crops
and in terms of pure steam and calculated the indicator
of the efficiency of soil conservation crops. The tests
allowed differentiating the crops on well, poorly and
very poorly in protecting forest soils from erosion
Peach fruit is much demanded worldwide. The
success of its cultivation depends on the optimal
plant placement of all the huge biodiversity
considering the cultivar demands. The northern
boundary of the peach cultivation passes through the
Kiev-Kharkov-Rostov-on-Don, Maikop, Nalchik,
Grozny, Astrakhan (Witkowski, 2003). However,
because of extreme temperatures there are almost no
suitable areas for Peach crop cultivation in these
borderlands, in the Krasnodar and the Stavropol
regions. From the other hand, extreme temperatures
for peach cultivation in the humid Russian subtropics
were not observed. Spring frosts till -5 ° C were
observed in 2004, 2014. However, the cultivar
productivity in the region influenced by the duration
of low temperatures (7,2 ° C and below) that were
observed from December to March. The amount of
low temperatures for each cultivar was established
using the highest coefficient of yield determination,
depending on the temperature, amount of
precipitation and the "cooling unit." The yield of
peach cultivars is closely linked with the abovementioned
agro-climatic conditions during the
flowering period. Paired correlation coefficients of
yield with precipitation and with temperatures (for
most cultivars) were negative, and since they are
unregulated value, the flowering phase is crucial for
peach culture in the Russian subtropics
