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
Barley is one of the important fodder crops. In modern
Russia barley is sown throughout the farming areas.
The effectiveness of barley cultivation in some years is
reduced due to the infestation with helminthosporiosis.
Net blotch of barley Drechslera teres is a widespread
and highly destructive disease in the world including
Russia. In recent years the disease has been
progressing in all grain-producing countries. Yield
reduction due to the strong development of the blotch
can reach up to 45%. Most cultivated barley varieties
are susceptible to Drechslera teres. Нelminthosporiosis
are characterized by greater variability and rapid
adaptation to new varieties of host plants. In order to
solve successfully the problem of barley immunity to
net blotch it’s necessary to conduct genetics and
population studies of the Hordeum vulgare -
Drechslera teres pathosystem
The present article is concerning with the research of
influence of new mineral additive «Koretron» in diets
for young pigs on meat performance. The mineral
additive «Koretron» adsorbs and removes mycotoxins
from the body and is the source of water-soluble
silicon, which is necessary for stable functioning of
intestine and stomach smooth muscles and for
improving of calcium digestibility. It is proved, that
the considered feed additive has positive effect for
animal growth intensity because it has contributed to
increasing of both total and relative weight gain of
young pigs on fattening. It is determined, that the
mineral additive «Koretron» has positive influence on
meat productivity of animals from the test group:
killing-out percent, hot carcass weight, rib-eye area as
well as weight and meat yield, fleshing index have
been increased. The considered mineral additive has
contributed to improving of chemical composition of
meat: the content of dry matter both in the average
meat sample and in the longissimus dorsi, content of
nutrients synthesized in carcass meat, energy value of
carcass meat, biological value of meat have been
increased. The data received during our test give
evidence of high bioavailability of water soluble
silicon in tested additive, which has activated
metabolic processes in the bodies of young pigs on
fattening and, as a consequence, the gain of their live
weight has been increased and morphological structure
of carcasses and meat quality have been improved
The use of physical factors for preplant stimulation
of seeds increases vigor, germination and improves
the yield of agricultural products. One of the effective
ways to improve seed grain quality is to impact
on the seeds using physical factors, in particular, an
alternating electromagnetic field of industrial frequency
of 50 Hz (EMF of IF of 50 Hz). We studied
the impact of EMF of IF of 50 Hz on the energy
germination of mid-ripening spring barley seeds of
promising varieties Vakula, Vikont, Ratnik. Carrying
out the experimental studies we used a laboratory
setup with annular pole points of rectangular
cross section. Our disperse analysis resulted in data
on germinative energy of seeds of spring barley
varieties Vakula, Vikont, Ratnik, which showed that
while treating seeds of spring barley by an alternating
electromagnetic field of industrial frequency of
50Hz, we obtained the best values of germinative
energy of seeds of Variety Vikont with a mode of
processing being equal to W = 16%, T = 2 c, L =
0,03 m
This article is devoted to studying the influence of
conditions of keeping and feedings on broilers of Hubbard
RedBro cross, and the quality of the received
products in case of application of floor and cellular
content in the conditions of a farm. It was found that
when receiving a feed of its own production with the
use of feed ingredients grown in farms without pesticides,
recorded a statistically significant reduction in
the potentially dangerous health animal substances. As
compared with a factory forage therein reduced pesticide
content by 14 times, mercury and arsenic is 24
times, 5 times cadmium, lead 10 times. Results of
studying of economic indicators of cultivation of
broilers of cross Hubbard RedBro and also chemical
composition and quality of carcasses demonstrated that
the essential difference between a floor and cellular
condition of keeping is not established, however use of
a diet on the basis of what forages promoted statistically
reliable decrease in concentration of toxic metals in
muscles of a bird of experienced groups. As a result it
was found that use of the researched compound feed in
diets of broilers raised indicators of biosafety and provided
ecologically safe (“organic”) meat products of
poultry farming
The influence of the crop rotation type, predecessor and different doses of mineral fertilizers on the yield of winter wheat varieties was investigated and bioenergetics estimation was given. Investigations were carried out in the North-Kuban Agricultural Experiment Station in two ten field crop rotation: grain tillage and grain - grass tillage rotation of prolonged stationary experience. The soil is the black soil, low in humus, powerful, with humus content (0-30sm), depending on the power of nutrition backgrounds in the arable soil layer. It was found that the selection of predecessors and the differentiated application of mineral fertilizers ensure stable high yields of grain and they exceed the varieties without fertilizers by 40-79%. Winter wheat yield depends on the crop rotation of 8-15%; from its predecessor - 15-18% and 27-31% of the fertilizer. A strong correlation between yield and agronomic methods was determined. The most effective predecessor for the wheat cultivation by the turnover of furrow slice is sainfoin, peas and wheat. More labor intensive and energy-consuming predecessors are grain maize and sugar beet
In the world, huge work is being done to create global
information banks of plant genetic resources. The need
for conservation and rational use of genetic resources
in modern conditions has become very relevant.
Genetic collections are the basis for selection work:
creating new varieties, replenishing the assortment
with new, classic, introduced and native varieties,
adapted to the natural (soil and climatic) conditions of
the cultivation sites. In the Anapa ampelographic
collection, 4911 varieties of various ecogeographical
and genetic origin are represented, the use of which
provides great opportunities for creating and breeding
new varieties, their state testing and zoning. In the
gene pool of the ampelographic collection, most
varieties of V. vinifera L. grapes are represented by
local honeycombs of different regions of the grape
culture, and more than one fourth of varieties of V.
vinifera L. are obtained from intraspecific crossings.
Despite the value of local varieties of grapes, they do
not always meet all the requirements of production.
Therefore, to improve the local assortment, it is
necessary to carry out selection - breeding new
varieties of grapes. This article presents the long-term
results of the work on the selection of varieties of table
and technical directions in the Anapa ampelographic
collection used for breeding. Also, the role of the
genetic collection in the creation of new generation
varieties by combinative selection is shown - as
donors for creating new varieties of grapes. Dedicated
varieties are the sources of valuable traits, which are given primary importance and are especially important
for the viticulture of the Russian Federation
