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
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 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%
The influence of growth, its ripened part and the
diameter of the vine at the base of the shoot on the
growth power of 922 seedlings of 55 combinations of
crosses in 2011 and 2012 was studied (planting scheme
3 x 1 m), seedlings of grapes of the second and third
years of vegetation in the field conditions of the
Southern coast of Crimea. The mean vine maturation
for all populations was 64.7%, the diameter at the base
of the shoots was 3.3 mm. After pruning to reverse
growth, in the third year of vegetation of seedlings
(2014), the length of growth of shoots increased
significantly and the average for populations it became
73.3 cm. The coefficient of variation increased, 26%, -
it acquired the character of a significant deviation from
the general population. This happened because the
seedlings, which had a vine growth less than 25 cm in
the second year of vegetation, had a growth of only 35
cm in the third year, whereas in all seedlings that had a
growth of more than 30 cm, in the following year shoots increased almost 1, 5 and 2 times more.
Formulas are proposed for estimating the growth force
of seedlings according to the 9-score scale OIV (OIV)
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
From 2011 to 2015 in the laboratory conditions there
were studied the physical properties of absorbents in the
controlled environment. There was defined that in the
variant of the "soil+water" the usual colloidal mass is
formed and in variants "soil+absorbents+water" - a
mixture of soil and gel. There was determined that the
least diurnal evaporation was fixed at the use of the
mixture: soil+ preparation “Ecogel-1”. In the control
variant of the experiment the full water evaporation was
marked on 31st day after beginning of the experiment, in
the variant with the use of the absorbent Aqua Life the
whole water evaporated on 48th day, and at the use of
preparations Ecogel-1 and Ecogel-2 the duration of
evaporation of the same amount of water supply at
temperature 22-24оС and air moisture in 55-60%
continued 57-65 days. In the result of five-year
laboratory researches there was determined the
possibility of development of water-saving technology
for fruit plantations. When we used absorbents
(granules, powders) in planting process and watering
resulting the gel-like mass completely collapses the root
system of fruit plants and the operation of the system
"soil-roots-leaves" will not depend on the physical
condition of soil and environment due to water
consumption for transpiration
A variety determines the direction of use of grape
products and plays a leading role in improving its
quality. Preservation of genetic resources of grapes
and their studying are very important for modern
science. The studied material makes it possible to use
the selected genetic characteristics for breeding new
varieties of grapes, taking into account the
requirements, and introducing them into production, as
well as highlighting the most valuable varieties for
transferring them to the state variety testing. Among a
wide variety of grape varieties, in the ampelographic
collection there are varieties of AZOSVIV selection of
the technical direction: Krasnostop AZOS and
Dostoiniy, for which complete phenotyping was
carried out. The phenological and agrobiological
information on the grape varieties studied for 2015-
2017 is collected. The presented grades of grapes of
the technical direction are characterized by high
quality of production. The wines from the varieties
Krasnostop AZOS and Dostoiniy are competitive,
characterized with high consumer properties; they
enjoy the well-deserved fame and were nominees of
exhibitions and holders of diplomas repeatedly. Based
on the results of microsatellite profiling, the varieties
showed a sort-specific general combination of alleles.
At the same time, in each locus there is one identical allele, which corresponds to the fact that the varieties
Krasnostop AZOS and Dostoiniy have one common
parent (Phylloxer-resistant Gemete). The received
formulas of a variety (DNA-passports) in practice can
be effectively applied to determine the cleanliness of
planting stock and plantations of grapes, specification
of the parent forms of the sample and in the disputed
questions of the authorship of the variety. The study
was supported by Federal Agency for Scientific
Organizations program for support the bioresource
collections
The results of the study of physiological and biochemical parameters of plum plants, changing when infecting plants Plum pox potyvirus (PPV) are shown. It was found that the infected leaves at the stage of full development of the content chlorophyll a reduced by 30 % in variety Stanley and by 6 % in Kabardinskaya rannaya, chlorophyll b in less than 49 % at Stanley, 37% in Kabardinskaya rannaya, carotenoids are less than 22 % in the variety Stanley and by 11% in the variety Kabardinskaya rannaya . Leaves infected with the virus pox (PPV), in comparison with not infected, the amount of protein were decreasing: in the variety Stanley by 21 %, in the variety Kabardinskaya rannaya by 28 %. In the period of active growth of the leaves change in the content of pigments and protein is more intense. The content of lignin in the tissues of leaves, infected with the virus pox (PPV), in comparison with not infected in the variety Stanley was below on 13 % and in the variety Kabardinskaya rannaya - 8 %. The total content of water of infected tissue on the stage of a full-time development is reduced in patients leaves as compared with not infected 11 % in the variety Stanley and by 1 % in the variety of Kabardinskaya rannaya. Throughout the period of development of foliage studied parameters vary depending on the variety
