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
The experiments were conducted on bull-calf of Kazakh white breed at the age of 12 months. In the capacity of feed additives there were used "Yoddar-Zn", which consists of microelements as iodine and zinc in organic form, and the additive "Glimalask-Vet" based on organic acids (I gr.). A second group of animals received only a basic diet with "Yoddar-Zn» (II gr.) feed additives. In the organism of experimental groups of calves, the transformation proceeded more intensively for nutrient feed. This has contributed to increase the intensity of their growth, slaughter performance and the quality of the resulting beef. Bulls that received a ration feed additives had a live weight more on 35,9, and 20,4 kg, carcass weight after slaughter - at 22,27 and 11,47 kg, and the mass of flesh - at 20,9 and 8,50 kg., compared with the control. The average sample flesh of carcass fat content was higher by 1,25 and 0,74%, protein – 0,68 and 0,47%, iodine - at 39,30 and 26,71%. The animals of experimental groups in the edible portion of the carcass was synthesized as compared to control, more protein on 5,86 and 10,71% and energy - on 10,95 and 5,02%. The highest efficiency established at complex using both feed additives. Estimation of economic efficiency of use of these feed additives showed a decrease in cost and increase in profitability of beef production
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
Analysis of rice market in the country was conducted,
as well as assortment of rice products was studied. It is
shown that rice is the most popular grain in Russian
Federation and in percentage of cereal products in
shops they occupy 29% and in diet of Russian people
– 41%. It is found that in Russia round grain japonica
varieties are the most popular kind. It is mentioned
that for the last years consumer market demands
diversity of rice products, including long-grain and
exclusive varieties, imported from abroad. It is shown
that in big cities demand for such products has
increased from 5% to 15%. Analysis of milled rice
balance was conducted. It is found that volume of
milled rice in the domestic market of the country is
annually about 680-800 thousand tons exceeding the
average demand value by 54,8 to 172,3 thousand tons.
Promising breeding directions are observed for
increasing assortment of rice products in Russian
markets with a view to import substitution. It is
mentione that Russian breeders have developed group
of exclusive varieties: Rubin, Mars, Viola, Violetta,
Avstral, Ivushka, Natasha, Aromir etc. It is shown that
special purpose varieties currently occupy 3,5% of rice
acreage in the Krasnodar region and their cost is by
20-70% higher than that of traditional rice varieties. It
was found that for their implementation into
production and promotion on the consumer market we
need to develop agricultural techniques of cultivation
and seed production scheme in accordance with the
biological characteristics, conduct marketing
activities, promotion of a healthy diet
In order to find compounds that increase sugar beet
resistance to the adverse effects of herbicides, a
series of pyridylhydrazone derivatives have been
synthesized. The protective effect of new
compounds for the herbicide mixture Betanal,
Lontrel and Super Zeleke was studied in field
conditions. The effect of pyridylhydrazones on the
synthesis of photosynthetic pigments in leaves was
investigated. Substances with a high protective
effect were found
The researches of the quality of 34 donor cows estrus
detection during superovulation induction period, after
Pg F2α injections were carried out. The clinical heat
index was set up and applied. The clinical heat index
is clinical prognostic criterion of successfulness of
superovulation induction and embryo productivity. It
was shown that donor cows showing signs of oestrus
during 48-72 hours after Pg F2α injections had the
best embryo collection qualities while certain increase
of degenerated or aborted embryos and unfertilized
oocytes is determined in embryo collections from
cows showing signs of oestrus before or after that
period
The article presents the results of studying the impact of different options for cutting fruit vines on the growth and productivity of shoots of the grapes. The obtained experimental data indicate the excessive overload of vines with eyes and shoots when performing contour trimming bushes without normalizing the choice of shoots, in comparison with other variants of experience. A significant increase of eyes on the vines when performing contour cutting was because during this method of cutting, the cutoff is at a certain level all the shoots are horizontal on the arm vines. A big load of vines shoots when performing contour cutting has reduced the length of shoots at 48 – 51%, and leaf area developed on the shoots of 53 – 54%. While the lowest productivity was different shoots developed on the vines in 3 variant, because here the contour cutting vines was not accompanied by a subsequent breaking of superfluous shoots, which have overloaded the bushes shoots. At the same time, contour cutting vines with subsequent breaking of the normalizing excess shoots were allowed to grow for fruiting the bushes a sufficient amount of normally developed shoots with high productivity and good quality bunches
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
