The article presents a study of acclimatization characteristics and the effectiveness in the use of Holstein black-and-white cattle imported from Germany, Denmark and the USA under the conditions of the Central Non-Black Soil Area of Russia. The analysis shows that the imported animals are exposed to a number of stress factors that often cause the diseases and serious losses of cattle. The main reasons for the losses of heifers were the pathologies of the reproductive organs and the mammary gland (26,3%), locomotor system and distal extremities (15%), respiratory organs (21,2%), etc. The highest-producing dairy cows were those imported from the USA (9158 kg of milk throughout the first lactation). For the yield of milk, they are superior to animals imported from Germany in 1828 kg (P≥0,999) and those imported from Denmark in 1184 kg (P≥0,999). The average American Holsteins’ milk over a 305-day lactation is higher in fat (4,14%) than that of their German (in 0,28%) and Danish (in 0,21%) counterparts (P≥0,999). The same tendency is observed in the protein content in the milk
To study the effect of pumpkin flour on the
physical and chemical parameters of semi-finished
and finished products, 10, 15, 20 % of the weight
of wheat flour in the dough was incorporated to the
dough mass. As a result of the research and the
analysis of wafers with different PF dosages, the
dosage of 15 % pumpkin seed flour from the wheat
flour mass in the dough was accepted as the
optimum one. After selecting the optimum dosage,
the experiment on identifying the dependence of
dough viscosity on the shear rate was carried out.
The samples were taken without adding PF into
dough and with adding PF for 15% from the
weight of the flour in the dough. The results
showed that the viscosity of the control dough
sample was higher than that with 15% of flour
from pumpkin seeds. This is due to the general
decrease of the amount of swellable proteins in the
dough due to the incorporation of PF. Thus, we can
conclude that the introduction of the investigated
additive into the wafer dough does not obstruct
dosing the semifinished product into the wafer
moulds. The analysis of the obtained data as a
result of the research work has shown that
incorporating pumpkin seeds flour into the recipe
of wafers is expedient both in terms of enriching
the product with proteins, fats and biologically
active substances and in terms of improving the
process in the production
Nicotiana tabacum and rustica are facultative self-pollinated plants, therefore, because of pollination peculiarities, specific methods are applicable to growing seeds of this plants. Researches on mass, individual and family, recurrent methods of seeds selection for productivity and sowing properties are carried in the institute for revealing most efficient methods of getting seeds. Seeds growing system for Nicotiana tabacum and rustica is a part of general seeds growing system for all agricultural plants and consists of breeding, testing new sorts, mass reproduction of seeds with retained biological and productivity properties, seeds harvesting and controlling their sort and sowing properties. Primary growing of nicotiana tabacum and rustica seeds is carried by individual and family or recurrent selection and further testing of chosen plants, distinctive for this sort, on economically valuable and biological properties. Peculiarities of each zoned sort are kept by retaining its primary genome with constant selection of highly productive genotypes, specific for this sort. Well-organized seed growing system leads to sort potential revealing. Biotype composition of sort is obviously changing in a few years, so primary seeds growing system should be constantly improved
Peach fruit is much demanded worldwide. The
success of its cultivation depends on the optimal
plant placement of all the huge biodiversity
considering the cultivar demands. The northern
boundary of the peach cultivation passes through the
Kiev-Kharkov-Rostov-on-Don, Maikop, Nalchik,
Grozny, Astrakhan (Witkowski, 2003). However,
because of extreme temperatures there are almost no
suitable areas for Peach crop cultivation in these
borderlands, in the Krasnodar and the Stavropol
regions. From the other hand, extreme temperatures
for peach cultivation in the humid Russian subtropics
were not observed. Spring frosts till -5 ° C were
observed in 2004, 2014. However, the cultivar
productivity in the region influenced by the duration
of low temperatures (7,2 ° C and below) that were
observed from December to March. The amount of
low temperatures for each cultivar was established
using the highest coefficient of yield determination,
depending on the temperature, amount of
precipitation and the "cooling unit." The yield of
peach cultivars is closely linked with the abovementioned
agro-climatic conditions during the
flowering period. Paired correlation coefficients of
yield with precipitation and with temperatures (for
most cultivars) were negative, and since they are
unregulated value, the flowering phase is crucial for
peach culture in the Russian subtropics
The article describes the efficiency of a feed additive
called "Tetra+" during chronic mycotoxicoses of pigs.
The purpose of carrying out series of experiments on
sows was to determine the therapeutic and
prophylactic effectiveness of innovative feed additive
"Tetra+" during combined chronic mycotoxicosis in
pigs and to study the influence of feed additive on the
growth, weight, preservation and overall resistance of
sows. The results of the experiments revealed that a
feed additive "Tetra+" has had a positive impact on
large-fruited of pigs; it can also be concluded that the
feed additive "Tetra+" has a positive effect on the
metabolism of proteins, carbohydrates and has
antitoxic properties
Ragweed plant became quarantine malware on the
territory of Southern Russia. In the Krasnodar region it
has been extended to the territory of more than 4.62
million hectares. In the areas of its growth, it causes
great damage to agriculture. By developing a strong
root system and aboveground, it inhibits the row crops,
especially sunflower. Another problem with this weed
is producing large amounts of pollen that causes
allergic reactions in the majority of residents of the
province. This article discusses the importance of
using modern methods of ragweed oppression,
including chemical and biological methods in
sunflower crops
In the conditions of the Krasnodar region, we consider
the quantitative and qualitative characteristics of seeds
obtained when using different schemes of organization
of hybrid seed production of squash in the Krasnodar
region. As a result of studying various techniques in the
production of hybrid seed of summer squash, we have
established the effectiveness of using open pollination,
and assessed the approbation of the signs of F1 hybrid
plants obtained under different schemes of organization
of hybrid seed production of squash
The article presents results of the evaluation of the
physiological aspects of growth and fruiting of peach
on clonal rootstock VVA-1, depending on the layout
of the trees. It was found that when forming a spindleshaped
crown, the most productive planting scheme is
5,0Ñ…1,5 m, at which the most optimized physiological
processes were proved
Using of seedling method for growing early potatoes
accelerates the starting processes of growth and
development of plants, and the application of
temporary covers of the nonwoven covering materials
protects the landing from sudden temperature changes
and relapsing frost. To receive seedlings of early
potatoes we used standard seed tubers of 60-80 g
weigh of the following varieties: Agata, Red Scarlett,
Kislovodskiy, Vershininskiy and Sheri. By the time of
planting in the ground, depending on the varieties, the
height of seedling was from 13 to 26 cm, the number
of leaves - 7-10 pieces. Conducting of trial unearthing
of potato showed that on 45 days after transplanting
into the ground (the second decade of May), it is
possible to receive up to 10, 5-11, 4 t/ha (Agata and
Red Scarlett varieties). On 55 days (the third decade of
May), the yield reached 26, 4 t/ha of standard tubers,
and in the first decade of June the yield was from 26, 4
to 50, 6 t/ha. The maximum yield of standard tubers of
50, 6 t/ha was obtained by lifting on 65 days with the
Red Scarlett variety. In the terms of the Astrakhan
region the growing of early potato by seedling method
with using of temporary cover allows to receive the
ultra-early harvest of marketable tubers in the II-III
decade of May
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
