An experiment was conducted to examine the effect
of fatty acid concentrate (FAC), as a new source of
energy and carnitine on performance, physiological
condition and meat quality of broiler chickens. In
experiment there were four groups of 80 chickens of
cross Hubbard each (males: females=40:40) in age
period 0-41 days. 1 group (control) received in during
the periods 0-14, 15-28 and 29-41days, sunflower oil
(SO) respectively 5.34%, 5.50%, and 6.10%, group 2
received the same amounts of FAC instead SO, 3
group - mixture SO:FAC (50:50), 4 group -FAC +
0,25% carnitine. Final body weight: 1 group =
2574±29 g, 2 group FAC= 2553±27 g 3 group SO +
FAC = 2531±34 g., 4 group FAC+0,25 carnitine =
2520±34 g. Feed conversion, digestibility of
nutrients, blood hematology and biochemistry, the
condition of organs, meat quality and cutting of
carcass of chickens on FAC had no any differences
from the same signs in chicks on SO. Carnitine had a
positive effect on chicken growth only in the period
0-14 and less 15-28 days; in the period 29-41 days
daily gain was below, than that in 1-3 groups.
Canitine reduced the content of liver fat. Outcome:
FAC is a satisfactory source of energy, comparable
with vegetable oils. The price of FAC is 30% lower
in comparison with sunflower oil and soybean oils, therefore its use in broiler poultry farming instead of
vegetable oils will be of great economic importance
The purpose of the research is to compare the effect
of a new symbiotic feed supplement created based
on propionic and lactic acid bacteria with a widely
used domestic and foreign enzyme-probiotic
preparations in chickens 0-28 days of age of the
Lohmann Brown egg cross. In the experiment, there
were six groups of chickens: group 1 received basal
diet (BD); group 2 – BD + symbiotic preparation;
group 3 – BD + Bacell; group 4 – BD + Agrocell;
group 5 – BD + Agroksil; group 6 – BD + Ollzaym
Vegpro. Average daily gain, food conversion rate
per 1g of weight gain, digestibility of organic matter,
crude protein, crude fiber, crude fat, made up
respectively: group 1 – 8.17, 1.91, 71.4, 58.3, 68.0,
81.1; group 2 ˗ 8.36, 1.90, 72.4, 60.2, 69.7, 88.1;
group 3 – 8.13, 1.91, 73.1, 60.2, 69.7, 88.1; group 4
– 8.33, 1.86, 74.2, 62.5, 72.2, 87.6; group 5 – 8.50,
1.83, 77.3, 64.1, 73.4, 95.4; group 6 – 7.91, 1.92,
73.2, 67.5, 70.7, 94.3. The growth rate of chickens
fed with symbiotic feed supplement was 2.3%
higher than in the control and they showed the
highest fiber digestibility. The chickens on diet with
Agroksil enzyme efficiently raised growth rate
(+4%) and reduced feed costs (-4.2%). Agrocell
increased weight gain by 2% and reduce feed costs
by 2.6%. The growth rate of chickens fed Ollazaym
Vegpro was the lowest (96.8% of control), despite
the fact that it increased significantly the
digestibility of crude protein, but slightly improved
the digestibility of other nutrients. Outcome:
symbiotic feed supplement may be of interest as a
means of increasing the productivity of chickens
The article presents the data on the formation of the embryonic fruitfulness of central ovaries of wintering buds of the group of technical grape varieties with white berries - White Muscat; Pinot White, Chardonnay, Citron Magaracha, Pervenets Magaracha; Riesling, Viorica, Riton, Crystal in the conditions of Anapa-Taman zone. There were revealed the rates of embryonic fruitfulness of central ovaries of buds of studied cultivars and fruiting indices of vegetative shoots developed from them. In all studied grape varieties there was revealed a high percentage of fruitful buds from 84,1 in the variety of Riton at 97.2 at Viorica; and the percentage of fertile vegetative shoots from 81,8 at the variety Citron Magaracha to 97.2 in the variety White Muscat. At the leveled load of bushes, vegetative shoots and the same scheme of planting of bushes (3 x 2 m), the highest yield in terms per hectare showed the varieties Pervenets Magaracha, Viorica, Riton, Crystal, Riesling and Citron Magarach. When assessing the economic efficiency the highest net income and level of profitability were identified in the varieties of Citron Magaracha, Pervenets Magaracha, Viorica and Riton. In order to determine which buds will give us shoots with large, well-developed (well-differentiated) buds, and which will not give (weakly differentiated), it is necessary "to look inside a bud". But even already formed germs of inflorescences in the bud are able in a few days in spring or dedifferentiate or degrade depending on the influence of external conditions. Scientists have learned to use this ability to increase the maximum possible yield in years of severe damage of grape by frosts. Firstly, in frosty winters the central buds wither out. The replacing buds usually have poor fruiting and bad productivity during years. In such cases, it is more profitable to conduct a small cutting of angle buds arranged in a circle at the base of a shoot. At the beginning of the second vegetation phase, these buds will obtain the great bulk plastic substances, which will cause the dedifferentiation of rudiments of inflorescences in them. Thus, it is possible not only to restore rapidly the normal shape of a bush, but to obtain a good harvest this year
The modern cattle breeding in Russia is
characterized by dynamic development, development
of intensive technologies, increase in production, but
at the same time, there are problems of increase in
production of milk due to increase of dairy efficiency
of cows at the most effective manifestation of the
available level of their genetic potential. For the
solution of this problem, i.e. for genetic
improvement of dairy cattle, creation of new breeds,
intra pedigree or zone types, more than 100 thousand
of bulls with high genetics, and also 430 thousand
heifers were delivered to Russia for the last 10 years.
In this regard, the purpose of our researches was to
study the level of genetic potential of dairy cows in
breeding farms of "Nasha Rodina" of Gulkevichsky
region, Vasyurinsky milk farm of Dinsky region, the
Firm «Agrocomplex» of Vyselkovskiy region
(Gazyrskoye enterprise), "Urozhay" of Kanevskoy
region from 2000 to 2014, by using bulls of
Golshtinsky breed. Researches have shown that in
farms of the Krasnodar region producers with the
high level of potential from 10791,0 kg to 12045 kg
on milk were yield used on a breeding uterine
livestock; from 4,22 to 4,40% of fat; from 3,32 to
3,49% of protein in milk. As a result the level of
potential of daughters of bulls and cows in herds of
farms was from 7774 to 9144 kg of milk; from 3,89
to 4,05% of fat; from 3,26 to 3,67% of protein in
milk. However, genetic potential of new generation
of animals is shown not completely. It is influenced
by partial compliance of the created technological
conditions of biology of animals, and indicators of
breeding value of producers, with their prepatent
indicators. Calculations of breeding value indexes of
bulls – fathers of cows in the herd of "Urozhay" have
shown that each bull has its breeding value, an
ability to transfer the qualities to posterity. Bulls of
Golshtinsky breed of red – motley color ( Pan 2037
and Tulup 78160689), by results of comparison of
milk yields of daughters, mothers and
contemporaries, had negative prepatent indexes of
milk yield and milk protein content (according to
F.F. Eysper and V. Sidorova). The data confirm the
need of carrying out an obligatory index assessment
of bulls before their use on the farm in order to avoid receiving descendants with low dairy efficiency
Currently, due to the risk of global warming because
of increased concentrations of greenhouse gases in the
atmosphere, carbon-deposit function of forest
ecosystems, thanks to which stabilization of gas
composition of the atmosphere takes place, has great
importance [1]. Forest is one of the main components
of the biosphere. Forests protect soil from erosion,
provide stability hydrological regime of rivers, supply
atmosphere with oxygen, biologically active
substances, purify of harmful impurities, create
optimal environmental conditions and play an
important environmental role. However, because of
intensive anthropogenic influence (unregulated
logging, technogenic environmental pollution
recreation) forest ecosystems are experiencing stresses
at which irreversible processes of degradation of
communities of economically valuable main forestforming
species of both natural and artificial origin
take place [6]. Evaluating carbon-deposit function of
forest plantations, CO2 emissions to the atmosphere
through the soil respiration must be taken into account,
which can vary within wide limits. Productivity of
forests is largely driven by carbon dioxide, released
from the soil. Soil carbon dioxide provides demand of
forest plants for photosynthesis. With increasing
intensity of soil respiration, positive balance is
maintained [2]. Based on the method of V.I. Tarankov
for evaluation of carbon-deposit and oxygen-producing
functions of wood cenoses [2], similar research is
carried out in RSI "Kuban forestry", the KarachayCherkessia
Republic
The article gives the results of the three years of
research to identify the main species composition of
fungal pathogens when stratified open and closed
methods. Biological efficiency of Guapsin, 0,2%, and
Trichodermin, 0,5% is shown. During the period of
stratification, using an open method "on the water", the
following pathogens have evolved: Cladosporium
herbarum (18,6%), Trichotecium roseum (16,3%),
Phomopsis viticola (13,9%), Alternaria spp. (13,4%),
Penicillium sp. ( 9,1%), Aspergillus sp. (5,6%),
Pythium sp. (4,3%), Gonatobotrys flava (4,3%),
Mycelia sterilia (2,8%), Botrytis cinerea (2,2%). The
studies found that the close method of stratification in
the peat developed the following specific composition
of pathogens: Penicillium spp. (21,1%), Phomopsis
viticola (16,4%), Botrytis cinerea (15,3%),
Trichotecium roseum (11,1%), Alternaria spp. (8,2%),
Mycelia sterilia (1,0%). During the period of
stratification, biological efficiency Guapsin, 0.2%, and
Trichodermin, 0,5%, was 31,9-88,0% and 28,2-86,3%,
respectively
For the purpose of preservation of soil fertility at
relatively low economic expenses, we have conducted
researches on optimization of doses and combinations
of mineral fertilizers by cultivation of field corn hybrid
called "Krasnodar 382" in a stationary field experiment
of the Department of agrochemistry in the training farm
"Kuban", in the conditions of the leached chernozem of
Central zone of the Krasnodar region. The main impact
on receiving high-quality corn gives the content of plant
nutrients in soil. Our researches showed that the
application of the complete fertilizer in various doses
has had influence on the content of essential plant
nutrients in the soil. The maximal values of the content
of mineral nitrogen, available phosphorus and
exchangeable potassium during all phases of vegetation
have been got in options with double N60P60K40 and
triple N90P90K60 dose of the complete fertilizer.
Sufficient supplying the soil with plant nutrients by
fertilizing has entailed the enhance of corn yield. Great
crop of corn has been reaped during the experiment.
After three years of researches, the productivity has
reached averaged 58,7 cwt/hectare. The greatest
productivity has been received in the option with
application of triple and double dose of the complete
fertilizer and amounted 68,5 and 68,0 cwt/hectare, what
is 47% and 45,9% more, compared to the option
without any application of fertilizers. The main
substance, which defines nutritional value of corn, is
proteins. Application of fertilizers under the conditions
of our experiment has promoted enhancing the protein
content in corn. The application of mineral fertilizers
has promoted increase of the content of crude protein in
corn. Maximal it was in option with application of the
complete mineral fertilizer in the double dose of
N60P60K40 – 9.6%, when reaped protein has amounted 6,5 cwt/hectare. Therefore, it is possible to conclude
that it is most expedient to fertilize field corn with the
dose of N60P60K40 and N90P90K60
The biotechnology (year - round utilization of livestock and spirit wastages) was developed for the protection of farmlands and water objects. Technology of processing of organic wastages by means of earthworms (vermicomposting) gives the chance to use wastages of livestock complexes, to make a sewage disposal at minimum energy consumption. In the field experiment which was made in the training farm called "Kuban" for the detailed studying of influence of the held events there were put the platforms. The technique of probability of estimation of ameliorative condition of an irrigated field is given in the article. The nonparametric statistical assessment of degree of soil compliance to the normative conditions is defined
In the experimental work, we studied the effect of the
inulin prebiotic on the growth, development and
efficiency of growing broiler chickens of the Isa cross.
In accordance with the scheme of the experiment, the
first control group was fed a complete feed (CF) by
periods of growth. In the second group, inulin was
added to the CF for the first 21 days of growth. In the
third group prebiotic was added to the CF at the same
rate throughout the whole period of rearing the chicks
(42 days). In the second and third groups, we found the
tendency to increase the intensity of growth rate in
poultry by 1.6 and 3.0%, respectively, compared with
the control. Feed costs for weight gain were decreased
by 2.1-2.7%. In the chime of the blind processes of the
intestine of the chickens of 2-3 experimental groups it
was found the reduction of staphylococci and
enterococci CFU, while similar to the control group
lactobacilli CFU. The muscle tissue in the chickens of
experimental groups had greater protein content. The
optimal range of indicators is the use of inulin for the
first 21 days of rearing poultry. Because of the
production audit, an increase in live weight of chickens
was found, in the experimental group by 2.7% (p ≤
0.05), a decrease of feed costs by 7.5%, increase of the
survival rate of poultry by 2.0% and profitability by
3.1%
During the last century, in the biosphere occur expressed processes of soil degradation due to anthropogenic influence, which seriously change of top layer of soil. The agricultural landscape is allocated of noticeable accumulation of various wastes at expense of growing of food crops and grazing of farm animals, as well as due to mineral wastes generated in process production of building materials and fertilizers from natural raw. According to physical and chemical characteristics of wastes of plant origin and natural-raw wastes constitute a non-toxic highly dispersed connection with an admixture of different undecomposed organic and mineral substances. Specificity of physical state is determined there of high dispersion, which is represented by system particles of colloidal substances distributed in various environments. Colloids of natural-raw wastes are characterized by a low rate of diffusion; do not penetrate finely porous membrane of cell structures, different very nonequilibrium insolubility and specific chemical composition. For example, phosphogypsum is characterized by high concentration of sulfur and calcium, and trace amounts of entire table of D.I. Mendeleev. Organic wastes are made by variety of chemical compounds and high concentration of carbohydrates, proteins, fats and other organic substances
