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 results of trials of feed additives
called "Yoddar-Zn" and "Glimalask-Vet" to improve
quality characteristic of meat of beef cattle. It was
established that the most efficiency of these additives
was achieved when used in complex. The carcasses of
calves, which were consuming a complex of additives
"Yoddar-Zn” and “Glimalask-Vet” (I c.), contained
meat of the highest sort more than control by 6.48 kg,
the animals which consumed only "Yoddar-Zn” (II c.)
- 3.50 kg, the first-sort - at 15.19 and 7.86 kg. In
experimental groups of calves there were observed
more intense integral characteristics of meat color. The
flesh of carcasses from the calves of experimental
groups, the fat was higher than control, 0.13 and
0.07%, protein - by 1.79 and 0.97%. Animals
experimental groups synthesized more protein at 5.45
kg, or 13.70%, and 2.62 kg, or 6.59%, energy - to
304.3 MJ, or 18.17%, and 146.8 MJ, or 8.77%. Meat
of experimental animals, contained more essential
amino acids. Protein meat quality indicator was higher
than control, 0.73 and 0.28, amino acid index - by 0.17
and 0.04. The meat from calves of experimental group
had a higher culinary and technological parameters,
optimal fractional composition of muscle protein and
lipid composition of adipose tissue, better digestibility
The article contains complex research results dedicated
of reproduction the cattle of the animal breeding
industry in the agricultural holding called “Kuban”.
Key indicators characterizing reproductive function at
cows were set; they were estimated in terms of the
plans of the economy in the milk cattle breeding
industry. The reduced values of the birth-rate of calves
were revealed on 100 cows and in the term of the
production use of cows, their main reasons were set.
The performed calculations prove the possibility of
increasing the profitability of milk production
Productivity of seeds of cereal crops essentially
depends on the quality of the seed grain, which is
being defined both by biological condition of seeds
and technologies and technical resources, which are
being used in, machine processing of seed heap. In this
connection, different injuries of weevils which are
occurred while mechanical and thermomechanical
influences from tools of machines and aggregates have
got vital importance. Apart from the breaches of
integrity of the weevil’s cover there are also exist
traumatizing changes of its inside structures which are
frequently covered with casings and do not being
viewed with visual inspection. Conditions of inside
structures of weevils were researched with
radiographic method and also were defined possible
types of traumatizing changes which depend on
mechanical and thermomechanical influences, which
were eliminated in universal classification of injures
among the inside structures of seeds of agricultural
cultures. Also, wу have analyzed the influence of
chosen types of injuries on seeds’ sowing qualities and
found that all injures of weevils essentially and
differentially influenced the sowing and fruitful
qualities and should be considered while choosing the
technological schemes of preparation, working tools
and while tuning the aggregates’ regime of work
attached to the machine processing of grain and seed
heap
The influence of the predecessor and different doses of mineral fertilizers on the yield and the quality of the winter wheat cultivar ‘Krasnodar 99’ were investigated. Investigations were carried out in the North-Kuban Agricultural Experiment Station in two ten- course crop-rotations: grain plowing and grain - grass plowing (stationary experience). The soil is the black soil, low in humus, powerful, with humus content 3,95-4,00%, depending on the nutrition in the arable soil layer (0-30sm), mineral nitrogen is 5,9-8,3 mg / kg of soil, exchangeable potassium is 330-360 mg / kg of soil. It was found that the maximum value of the winter wheat crop structure elements is noticed in the fertilizer systems with complete mineral fertilizer, and the minimum value - with PK and NK. Winter wheat yield depends on the crop rotation of 8-15%; from its predecessor - 15-18% and 27-31% of the fertilizer. The protein content was mainly determined by the fertilizer dose. Enhanced and high doses of fertilizers contributed to an increase in the protein content to 12%.A strong correlation between protein content, agronomic methods and precipitation was determined
The provisions to improve the efficiency of vineyards
are the selection of varieties different by ripening,
adapted to local conditions, as well as the use of a new
generation of fertilizers. According to phenological
observations and actual production period, the varieties
of table grapes are divided into groups by ripeness –
early and middle. According to the yield, there were
emphasized the following varieties: in the early group
– Cardinal (11,3 t/ha), Vostorg (Delight) (11,2 t/ha),
Bogatyrskiy (10,9 t/ha); in the middle ripening group -
Kishmish luchistyj (11,2 t/ha), Moldova (11,2 t/ha),
with large clusters (266-453 g) and berries (3,2-7,0 g),
a berries’ crush resistance was from average 850 g to
high up to 1528 g, berries’ strength of attachment to
fruitstems was high – 259 and solid – 666 g. It was
observed the positive benefit of foliar application of a
new generation of micro fertilizers. In the phase of
ripening of berries the total length of shoots of
fertilized variants was above the control variant for the
variety Ranniy Magaracha on 2,6-13,4%, for the
Karaburnu on 2,5-13,9%. Maturing shoots in this
phase was on the variety Ranniy Magaracha – 76,5-
92,4% (control variant – 74,6%), while on the
Karaburnu variety – 72,8-83,1% (control variant –
70,9%). Fertilizers contributed to the increase of leaf
area on the Ranniy Magaracha variety on 3,9-15,9
thousand sq.m/ha (control variant – 20,0 thousand
sq.m/ha), on the variety Karaburnu on 3,4-13,1
thousand sq.m/ha (control variant – 22,8 thousand
sq.m/ha). The yielding capacity on the fertilized
variants have increased by 7,1-23,0% depending on the
variety. The maximum yielding capacity was obtained
when using compound nanotechnological fertilizer
Nagro on the variety Ranniy Magaracha – 13,4 t/ha
and on the variety Karaburnu – 15,5 t/ha
Currently, personal subsidiary farms (PSF) have an
important place in solving of the food security problem
in some regions and the country as a whole. The
organization of optimal and sustainable management
strategy of maintenance for PSF should be planned
according to the study of functioning of PSF. The
authors propose a unified methodical approach for
complex accounting of energy costs of external and
internal flows involved in the production of
agricultural products. Comparative energy
characteristic of the functioning of the two personal
subsidiary farms located in the Tomsk oblast and
having different socio-economic and climatic
conditions is presented in the article. Both farms are
located in the taiga zone of Western Siberia.
Calculations of the energy content of all the incoming
and outgoing flows involved in the economic activities
of PSF showed that the flow of technogenicanthropogenic
energy is the most energy-intensive for
both farms. Some conformity in the energy structure
of consumption of their own product takes place
despite the different types of stockbreeding
specialization. An assessment of the level of selfsufficiency
in food has shown that more favourable
socio-economic conditions create preconditions for an
increase of the anthropogenic flow. While PSF located
in remote areas are forced to conduct of business
activities with maximum using of natural resource
potential
High growth-rate of plantlet is the integral index of
intensity of physiological processes at rice and other
cultures. 20 typical plantlets from each of two
variants were studded (in the distilled water in
thermostat at a temperature 29° C) by:
length of embryonic root and coleoptile. Comparative
analysis of trait characterizing the growth rates of rice
varieties showed reliable advantage of Russian ones
above the Italian and Chinese. Local varieties,
regionalized until the year 2000, exceed new ones on
this trait. Highest growth rates were characterized by
medium grain samples. The white grain and red grain
varieties are excelled other groups on the height of
plantlet. Analysis rates of height of plantlets in the
distinguished groups showed the necessity of
prosecution of improvement of the above enumerated
signs at the varieties of late term of ripening, long
grain, with Waxy gene, colored grain. We recommend
to sow this type of varieties on fields with good
leveling, because of low speed of growth
Feijoa crop is valuable due to the complex of useful
traits (high frost resistance, big yield, ornamental
value and long profitable period). These fruits have
delicate flavor, nutritional and dietary properties. The
fruits are juicy with a pleasant, gentle, refreshing
sweet and sour taste, specific strawberry-pineapple
flavor and contain significant quantities of important
substances for the human body. Pectin (up to 2.5%),
sugars (6-14%), proteins, vitamins, organic acids,
mineral salts, etc. are among them. However, the
challenge of its cultivation is the lack of cultivars and
plantations are represented by a mixture of hybrids
originated from free pollination, and characterized by
a great variety in biological and morphological traits,
differing not only in yield, but in size, shape and
yield period. In this connection, the breeders faced
the objective to create new cultivars of feijoa, using
classical and modern breeding methods and available
genetic resources for commercial gardening and
production. Development of the core hybrid diversity
material and selection of promising forms are the
most important stages of the breeding process,
providing success of further breeding programs. The
breeding of varieties and forms for crossings was
carried out according to the principle of combining
the desirable traits of the obtained offspring. There
are direct and reverse crosses in six combinations
('Dachnaya' x 'Superba', 'September' x 'Superba',
'Dagomysskaya' x 'Superba', 'Superba' x 'Dachnaya',
'Superba' x 'September', Superba ; X 'Dachnaya'). The
viability of the pollen was evaluated prior to
pollination, by germination on a nutrient medium -
1% agar-agar + 15% sucrose. The degree of fertility
varied year by year: in 2015 - 60-62%, and in 2016 -
68-77-88%. The best crossing combinations were
established 'September' x 'Superba' and the 'Superba'
x 'Dagomyskaya for the creation of the hybrid
genepool of Feijoa sellowiana. A high percentage of germination of the feijoa seeds was noted in
combinations of 'Dagomyskaya' x 'Superba' (74%)
and 'Superba' x 'Dagomysskaya' (70%).
The increasing consumption of forest resources causes
a greater anthropogenic impact on forest ecosystems
and leads to a negative impact on both biodiversity and
the environment as a whole. In this article, the
sustainability of forest phytocenosises of southeast of
Western Siberia is assessed using the example of
Tomsk region. The analysis of the status and dynamics
of the forests of Tomsk region has been assessed. The
main factors negatively affecting the biodiversity of
forests of Tomsk region were analyzed. The forests
cover extensive areas; therefore, the studies were
carried out based on the data from the State Forestry
Register of the Russian Federation for the period from
2008 to 2015. According to the results of the study, the
sustainability of forest phytocenosises has increased
significantly in recent years, which can be explained
by its strengthened ability to maintain the current state
under the influence of external factors. This work
considers such causes of damage and death of forest
plantations as pests, forest diseases, unfavorable soil
and climate impacts, forest fires, as these are the main
and most massive phenomena that cause the greatest
damage to forest. It is possible to see the dynamics of
damage and death of forest plantations on the figures
presented in the article
