This article presents the results of the impact of
"Gorlinka" mustard protein-containing feed
concentrate in the feeding of broiler chicken of the
cross of "Cobb-500" on their performance and
nutrient digestibility of the feed. The studies were
conducted in the conditions of Krasnodonskaya
Poultry farm in the Ilovlinskiy district of the
Volgograd region. Full or partial replacement of
sunflower meal with "Gorlinka" mustard proteincontaining
feed concentrate in the feed mixture for
the experimental broiler chickens contributes to the
increase of the coefficients of digestibility of nutrients
compared to the birds in the control group. The use of "Gorlinka" mustard protein-containing feed
concentrate in the composition of feed for broiler
chickens has contributed to higher coefficients of
digestibility of nutrients: dry matter – 0.51-1,37%,
organic matter – 0.6-1,99 %, crude protein by 0.8-
2,24 %, crude fiber – 0,34-1,65 %; crude fat – 0.94-
2,29%, compared to the birds in the control group.
Nitrogen balance was positive in all groups; the use of
nitrogen from the accepted experimental broiler
chickens was higher in the experimental groups than
in the control by 2.89-of 7.93 %. The use of nitrogen
from digested nitrogen was higher in the experimental
groups in comparison with the analogues from the
control group by 2.65-of 7.97 %. The use of calcium
and phosphorus by poultry was also higher in the
experimental groups
This article presents the results of using "Gorlinka"
mustard protein-containing feed concentrate, instead
of sunflower meal in the feeding of broiler chickens
of the cross of "Cobb-500". The studies were
conducted in the conditions of Krasnodonskaya
Poultry farm of the Ilovlinskiy district of the
Volgograd region. Replacing sunflower meal with a
product of processing of oilseeds which is "Gorlinka"
mustard protein-containing concentrate, in the feed
mixture in the experimental broilers had a positive
impact on the productivity, physiological state of the
birds, product quality and economic performance.
The use of this mustard protein-containing feed
concentrate in feeding of meat birds contributes to the increase of live weight by 3.46-of 6.65% and
slaughter yield by 1.38-1.98% and improvement of
quality indicators of the carcasses. Morphological and
biochemical parameters in experimental broiler
chickens in all the groups were within the
physiological norm, which indicates a normally
occurring redox processes in the poultry organism.
However, adding "Gorlinka" mustard proteincontaining
feed concentrate into experimental feed for
broiler chickens contributed to the increase in the
content of total protein, calcium, phosphorus in blood
serum in comparison with analogues from the control
group that received sunflower cake. As a result of the
research, the economic effect in the experimental
groups was up 710,40-1085,53 rubles
In the conditions of grey forest soils in the Bryansk
region among the fodder crops widespread mixed legume-cereal
crops. The results showed that the photosynthetic
activity of cereals and leguminous crops and
their yields in mixed crops depended on made of biological
and mineral nitrogen fertilizers. It is established
that the nitrogen in the form of ammonium nitrate has
a positive impact on the formation of assimilating leaf
surface, photosynthetic potential and net productivity
and yield of grain mixture in lupine-barley and soybean
-barley cropping and pea-barley crops the use of
nitrogen in the form of potassium nitrate was more
favorable. It was found that in lupine-barley crops the
active symbiotic potential has increased by 25,5% and
the yield increased by 21,3% , in soybean-barley crops
28,5% and 19,2% respectively, due to the joint use of a
mixture of symbiotic and associative rhizobacteria and
mineral nitrogen in the form of ammonium nitrate in
the dose of N60. In pea-barley agrocenosis it has improved
the efficiency of cultivation of joint application
of mixed inoculant symbiotic and associative rhizobacteria
on the background of the application of mineral
nitrogen in the form of potassium nitrate in the dose of
N60, where there was an increase of the active symbiotic
potential by 34,7% and grain yield by 24,7% compared
to the option when adding the mixture of biological
products
The article examines the creation of the expert system
in the development of epiphytotics in winter bread
wheat sowing. Increasing the accuracy of the forecast
epiphytotics should be based on the improvement
forecasting of move daily temperature (minimum,
maximum and average). In this case, the calculation
algorithm must not be cumbersome. In the algorithm,
there are indicators of cyclical annual variations of
temperature, i.e. the change in average daily
temperatures for the year. For the treatment method of
local forecast of daily average temperatures during the
year used data of meteorological station for 9 years.
Having considered the main issues to epidemics of
brown rust and its influence on the production of
wheat cenoses, you can proceed to the modeling expert
logic. The analysis includes the following indicators:
cultivated variety; agricultural machinery (predecessor,
fertilizer, pre-processing, and others.); general
condition of sowing; phase of plant development at the
time of the field survey; date of onset of the disease (if
selected); prevalence of sowing at the time of
observation. Installed that the purposeful creation of
varieties of winter wheat resistant to the pathogen, it is
necessary to carry out environmental testing stability
as a latent breeding and recommended sources and
sustainability of donors, which will allow to plan
economic occupancy resistant genotypes of winter
wheat
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
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
Modern commodity sturgeon breeding is one of the
profitable and dynamically developing directions of
fish farming in the Russian Federation. Only the
system of Rosrybhoz has more than 40 enterprises of
different ownership forms for the cultivation of
sturgeons. In 2012, in agricultural farming of the
Russian Federation we had grown more than 2.0
thousand tons of sturgeon. Crucial role to maintain
normal functioning of the body of the fish when
grown in closed recirculation systems plays complete
and balanced nutrition. Proper organization of
biologically full feeding of fish helps to maximize
expression of their genetic potential. The article
presents the results of the researches of the efficiency
of using feed concentrate from vegetable raw
materials called "Sarepta" in the composition of feed
additives for 2-year old Russian sturgeons
The article considers tendencies of development of the
agroindustrial complex based on intellectualization of
technical means, development and implementation of
robotic machines in different manufacturing operations.
We have analyzed design features and practical
application of robots with vision systems in crop
production. We have identified the feasibility and
effectiveness of the introduction of new physical
methods of processing plants by means of robotic tools
that will automate technological processes of
processing plants. The article describes the analysis of
the mobility of the model of robots developed in the
WIM based on mathematical simulation at different
operating conditions. To check the model, we present
calculations of the dynamic behavior of the robot body
at different driving modes. The study shows the graphs
of movement parameters obtained from the results of
simulation and dynamics of dispersal. The analysis
identified the advantages of technological application of the robot on the example of gardening
This article presents the results of the use of feed
concentrate from vegetable raw materials called
"Sarepta" in the amount of 5, 7.5% and 10% by
weight of the feed, instead of sunflower meal in the
feeding of Russian sturgeons. Studies have been
conducted among 3 year old Russian sturgeons in the
conditions of PRIBOY company in the Bykovsky
district of the Volgograd region. The experiment
lasted 24 weeks. Replacing sunflower meal with a
product of processing of oilseeds - feed concentrate
Sarepta, made from vegetable raw materials, in the
composition of feed for sturgeons had a positive
effect on live weight, absolute, average daily and
relative gains and costs of feed. The use of "Sarepta"
feed concentrate, made from vegetable raw materials
in the feeding of Russian sturgeon contributes to the
increase of live weight of 3.1-6.0 per cent, an absolute
increase of live weight by 5.07-9.82 percent, and
average daily and relative body weight increase. It
was also found, that we had a decrease in feed
consumption during the period of experience in the
experimental groups. Morphological and biochemical
parameters in experimental fish in all groups were
within the physiological norm, which indicates a
normally occurring redox processes in the body
The article reviews four variants of laying nurseries of
primary branches of seed production of long-grained
rice varieties of the Kuban breeding taking into
account their biological features, plots area ranges
from 0,7 m2
to 1,1 m2
, seeding rate for one family –
from 100 pcs./m 2 to 170 pcs./m2 . We have studied
traits of long-grained rice varieties of the Kuban
breeding - Ivushka, Avstral, Kurazh, affecting the
yield and quality of seeds: yield, multiplication factor
and fractional composition of seeds depending on
laying multiplication nursery of first year progeny.
The differences between varieties by the type of
tillering, vigor, germination of seeds depending on
planting system are shown. Optimal way for laying
seed nurseries is found: for long-grained varieties with
medium tillering (Kurazh type) – row length – 3,3 m
and seeding rate – 120 caryopses/m2
; for those with
intensive tillering (Ivushka type) – row length – 3,8 m
and seeding rate - 120 caryopses/m2
. This will allow
using mechanical method of sowing using selective
cassette seeding-machine in the primary seed
production, reducing cost of seed production and
increasing efficiency of labor, increasing volume of
seed production of long-grained rice varieties in short
terms and accelerating their implementation in the
Kuban region for import substitution
