The article presents the results of the investigation of
the influence of liposomal form of silymarin on the
physicochemical parameters of the meat of the broiler
chickens of the cross called Hubbard F15. The objects
of the investigation were: pectoral muscle, the preparation
called Liposil, which consists hepatoprotective
agent of silymarin, extracted from milk thistle in the
form of dry extract and soy phosphatidylcholine. Milk
thistle is known as a source of bioflavonoids, and has
long been used in folk medicine for diseases of the
liver. High bioavailability of silymarin, due to the
liposomal form, makes it possible to use it in lower
doses in comparison with the form of an extract. The
experiment of liposome silymarin used a dose of 40
mg / kg of feed discretely (5-7 th, 12-14 th, 19-21 th
and 28-30 th day) and daily as a supplement to the
basic diet during growth of broiler chickens of Hubbard
F-15. We have established, that Liposil increased
tryptophan content in the muscles and improved the
protein-quality quotient. We have found decreased fat
content and caloric value of pectoral muscle of experienced
group chickens. The findings suggest that we
have a positive effect of liposomal silymarin on nutritional
and dietary value of meat
The purpose of the researches was the necessity of
deep study of hydraulic dimensionless expense
descriptions of regulative organ of model standard of
band regulator of water, for rice checks. Rice is one
of the most moisture-loving agricultural cultures. Its
productivity straightly depends on adjusting of water
level in rice cotter pins on the different periods of
development of this culture: period of primary
submergence of check, fight against weeds, primary
vegetation, phases of bushing out, vegetations of
suckling and cereous ripeness. On each of the
considered periods of development of plant the
guided water level is needed, that high-quality can be
realized only at application of the systems of
automatic control. In rice irrigation systems there is
plenty enough of losses of water due to not managed
leakage in regulator flow and water level in the
closed position. An actual and meaningful task is
development, research and introduction in practice of
reliable and high-efficiency regulators expense and
water level for rice checks. The article presents
results of research of hydraulic dimensionless
expense descriptions of regulative organ of model
standard, developed by us. Intercommunication of
degree of influence is investigational, on the basis of
application of methods of planning of experiment, on
the function of response, which dimensionless
expense description of regulative organ of model
standard of band regulator of water, relations of
diameters of the downlow openings, is taken for, at
the different relation of workers pressures. From
appraised experimental data approximation
dependences, which were in same queue analysed for
the purpose cross-correlation connection,
determination, elasticity, are built. Also, in the article
there is an estimation of statistical meaningfulness of
the built model of regression given with the use of
criterion of F - Fishera and parameters of
equalization of regression with the use of criterion of
t - St'yudenta, at the set level of meaningfulness α. At
the permanent relations of workers pressures the
analysis of sections of surface of response H/Нmax
0,6; 0,8; 1,0 shows that functions have extremums on a maximum. At minimum relations of workers
pressures H/Нmax equal 0,6 the maximal value of
function of response is equal 81% it will be at the
relation of diameters of the downlow openings of
d/dmax equal 0,9. With the increase of relation of
workers pressures H/Нmax to 0,8 have a trend of
maximum toward an increase and here he comes at
the value of function of response equal 94% and
relation of diameters of the downlow openings of
d/dmax equal 0,92. Further increase of relation of
workers pressures of H/Нmax to 1,0 also results in
the trend of a maximum of function of response
which arrives at a value 118%, here the relation of
diameters of the downlow openings of d/dmax is
equal to 0,94. The combined analysis of curves
shows that at any relation of workers pressures, the
degree of influence on the function of response
increases due to more relation of diameters of the
downlow openings
The article presents results of the experiment to study
the influence of vitamins and minerals preparation
with folic acid Vitoligo M at the reproductive
functions of sows. It is established that prilificacy of
sows was more at 12,5-39,3%. The piglets of the
experimental groups had the best quality of growth and
livability. Blood chemistry parameters were better in
sows experimental groups. The experiment with lots of
animals confirmed the results of scientific experience.
The sows of the experimental groups had better
breeding efficiency
In recent years, due to the increasing aridity there was
an increase in the frequency of epiphytoties leaf disease
of barley. Therefore, we can see now how greatly
increased the need for the creation of resistant grades.
Introduction of the selection marker will significantly
speed up the breeding process for resistance to
pathogens. Employees of the All-Russian Institute of
Plant Protection recommended three genes - Rpt 1b,
Rpt 5, Rpt 6 to control the resistance to the pathogen
Pyrenophora teres for use in breeding programs in the
North Caucasus. Rpt 5 gene is one of the most efficient
one, because it determines the resistance to the eight
isolates of the fungus Pyrenophora teres of different
origin. In 2011, Australian scientists have discovered
microsatellite markers called Bmag0173 and HVM74,
closely linked to the gene Rpt5, which are used very
effectively in order to marker-assisted selection of
resistant grades in Australia and Canada. Due to the
urgency of creating new genotypes carrying resistance
genes to net blotch, that would be effective in the
Southern Federal Region, the staff of All-Russian
Scientific-research institute of Grain Crops after I.G.
Kalinenko and the All-Russian Research Institute of
Plant after N.I. Vavilov has developed a practical
strategy for the use of molecular techniques to create
barley grades resistant to this pathogen, which is being
successfully implemented
Diagnosis by PCR-RFLP (polymerase chain reaction –
polymorphism of the lengths of restriction fragments)
is the standard analysis of point mutations for the
diagnosis of allelic polymorphism of candidate genes
related with productive qualities of farm animals.
Along the length of the fragments (RFLP) make a
conclusion about the absence or presence of the point
mutation, and homozygosity or heterozygosity of the
individual. The aim of our work was the optimization
of protocols for conducting PCR-RFLP analysis for
genotyping sheep for genes of the growth hormone
gene differential growth factor and gene of calpastatin

Diseases cause great damage to agriculture, reducing
yields and decreasing its quality. The losses
are up to 20-30% of potential crop yields. Different
types of rust and powdery mildew cause significant
damage to wheat. Thereby, the growing of
varieties tolerant to these diseases is of great importance
at present. It allows solving such problems
as the improvement of stability of grain production
(especially in the epiphytotic time), improvement
of its quality and reduction of prime
cost of the product. Cultivation of resistant varieties
gives the opportunity to avoid a use of crop
protection chemicals and thus, to improve environment.
The researches were carried out in the
laboratory of intensive soft winter wheat breeding
and seed-growing of FSBSI ARRIGC after I.G.
Kalinenko in 2013-2015. The crop was sown in a
bare fallow. 275 samples of soft winter wheat from
the world collection VIR, Turkey (CIMMYT),
new varieties of domestic and foreign breeding,
varieties and constant selection lines of own selection
were the subjects of the study.
Favorable for disease development weather conditions
allowed evaluating collection samples according
to the degree of infection with leaf rust and powdery mildew under natural conditions.
According to a complex resistance to leaf rust and
powdery mildew we have distinguished the following
samples: ‘Nakhodka’, ‘1226/98’, ‘662/99’,
‘1366/08’, ‘Patriarkh’ (Russia); ‘Shestopalivka’(Ukraine);
‘Simonida’ (Serbia); ‘MV 15-04’
(Hungary); ‘Rialto’ (England); ‘Menestrel’
(France); ‘№42 CIMMYT’ (US). Thus, our conducted
study resulted in distinguishing the samples
of soft winter wheat which are resistant to leaf rust
and powdery mildew and are recommended to use
as a source of resistance and tolerance to these
pathogens. The samples with a combined resistance
to both pathogens are of particular interest
The key task of the agriculture in Russia is the further
improvement of grain production. Thus, prevention of
losses of winter wheat yields because of the diseases
remains relevant. The significance of varieties tolerant
to diseases, especially to smut (fungus) is of primary
importance. Therefore, it’s essential to create initial
material for breeding of the varieties tolerant to smut.
According to the results of the trials with artificial
infection with pathogens, among the samples of
winter wheat there have been identified varieties
belonging to different groups of tolerance to smut.
They are a highly sensitive cultivar ‘к-69361’
(Korea), a sensitive variety ‘Izyuminka’ (Russia),
moderately sensitive variety ‘Asket’ (Russia) and
almost tolerant variety ‘1621/03’ (Russia). We studied
the reaction of the hybrids F2 on infection with smut
in different variants of hybridization to obtain stable
progeny. The correlation between the number of
infected plants in parent and hybrid (F2) populations
have been considered. The productive tillering of the
plants has been determined in all variants of the trials;
it was the least one on the plants with 100% of
infected leaves. The hybrids F3 and F 4 have been
distributed according to the degree of their tolerance
to smut. For further work we have selected the lines
with practical resistance to smut (fungus)
There was given a review of the results of the study in
the conditions of sufficient moisture of Central
Ciscaucasia, the influence of planting terms and
presowing seed treatment by the drug called "TMTDplus",
containing Krezatsin growth stimulator in its
composition, on the development of corn hybrids of
different maturity groups of the selection of Krasnodar
Research Institute of Agriculture named after P.P.
Lukyanenko (Ross 199, Ross 299, Krasnodar 382 and
Krasnodar 410) and the All-Russian Research Institute
of Corn (Mashuk 170, Newton, RIC 345 and Eric), as
well as middle- maturity population Rossiyskaya 1.
The studies were conducted in accordance with the
thematic plan of scientific researches of the chair of
crop and forage production of the Stavropol State
Agrarian University. The soil surface of the
experimental station of StavrGAU was presented as
leached black soil. The technology of growing of
maize on the experimental plot corresponds to the
standard one for the present area and cultivar. The
predecessor is winter wheat. Sowing was performed in
three terms. The first (early) sowing term was carried
out at t = + 7 ... +8 ° C. The second (recommended) -
when t = + 10 ... + 12 ° C. The third (later) sowing
time was carried out at t = +15 ° C. The plant density:
early-maturing hybrids – 70 thousand pieces/ha, is
mid-maturing ones – 60 thousand pieces/ha, middleripe
– 50 thousand piece/ha, middle-later ones – 45
thousand pieces/ha. The scheme is single-row, with
spacing of 70 cm. The application of the studied drug
TMTD-plus helped to reduce the growing season of
maize plants for one - four days. Thus, changing the
sowing terms of maize hybrids and populations, we
can largely control the development of plants changing
the length of the growing season to two weeks and
form a harvesting conveyor, thereby reducing the
intensity of field work
