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
The analysis of milk technological properties of black-motley cows of both domestic and Dutch selection was conducted. It was established that the composition and technological properties of cow’s milk of both the domestic and Dutch selection meets the modern requirements to the main dairy products
The studies have determined the effect of bentonite clay, vitamin complex "microvan Blend" and BAKD of local raw materials for the viability, the growth and the development of the young rearing flocks of the “Hisex brown" egg cross. To improve the quality of the grown rearing flocks and pullets increased yield, egg poultry farms were proposed to use the bioactive feed additive (BFA) made from local cheap raw materials (bentonite clay, sunflower oil, drug-soluble vitamins A, D3, E and antioxidants)
In the article, the maintenance of heavy metals in fertilizers is resulted. The quantity of the years providing ecologically safe entering of mineral fertilizers before excess of maximum-permissible concentration of heavy metals in soil is calculated. The balance of heavy metals as micro – and ultra microelements in leached black soil is resulted

Characterized by high resistance to cold, drought and increased resistance to fungal diseases in comparison with varieties of Vitis vinifera. Lobes, the stamens and fully developed gynoecium. Bunch medium, often with tapered wing, the average density. Berry small, round, blue-black, with a thick waxy coating. The peel is medium thickness, dense, durable. Pulp and juice intensely colored. Sugar content is very high. Prolonged preservation of different crop on bushes. Variety intended for manufacturing intensely colored dry red wines of excellent grade and high-quality sparkling, dessert, sweet and liqueur wines; and is suitable for the manufacture of high quality strong colored juices. When used in blends with other varieties, it enhances color, flavor and improves the bouquet of wine
The efficiency of replacement of sunflower oilcake by rapeseed oilcake from double-zero rapeseed varieties was proved for mixed fodders for pigs
The article analyzes the state of the domestic beekeeping.
It is proposed, as a paradigm of the industrial
beekeeping, to use honey and pollination systems.
Over the past 25 years, because the hard economic
reforms in the public sector, there was almost double
reduction of honey collection. Russian beekeeping is in
the hard situation because of the low yields and the use
of outdated technologies. Russia's share in the global
honey market does not exceed 1 %. A more viable
was apiaries of private households. Beekeepers receive
a basic income from the sale of honey. Meanwhile, in
developed countries more than 60% of the income of
integrated use of honeybees account for pollination
activities. In modern conditions of the Russian vector
of development of beekeeping should be its production
and technological re-equipment, improving its bioecological
principles and socio - economic transformation
of the infrastructure sector. Using mobile honey-
pollination systems, which provide bees with feed
conveyor due to the frequent movement of the apiary,
honey plant and beekeepers can reduce the cost of
manual labor for loading and unloading hives. In the
Kuban Agrarian University we designed the pavilion
design (RF patent number 2,284,103 ), awarded with a
silver medal of Concours Lepine (France, Paris ). Using
a mobile pavilion allows to conduct all production
functions: honey and pollination production and reproduction,
ensuring the competitiveness of the industry
The technique of simulation of thermal processes in a container planting has been presented. The information about the distribution of the temperature inside the container has been obtained. The comparative analysis of single and double (pot-in-pot) containers has been done
The article contains the experience of the development
of the methodology and the computer program for
calculation of regional and local systems of pigs
hybridization at the example of the Rostov region
(Russia). Crossing the GP lines for F1 should be
organized in multiplier farm, which may be separate
farms and to be part of large commercial farms. For
the production of F1 in a multiplier farm, we must
breed a purebred specialized paternal and a maternal
line, selected on the effect of combining ability. For
the successful functioning of the system of
hybridization, it is necessary to build a genetic
pyramid, including breeding and genetic centers
(nucleus farm), multiplier farm, reproducing the
baseline. The article gives a detailed calculation of sow
population of levels of P, GP, GGP for maternal and
paternal breeds of pigs. The program uses user-defined
parameters of pigs productivity, of the simulated
population, and the parameters characterizing the
intensity of selection of young animals. To ensure
annual production of 1,822 million pigs in the Rostov
region it is necessary to provide the availability of
brood stock in the amount of 89 thousand heads, 6 800
heads in the structure of grandparent flocks (GP), 730 heads in the structure of the Grand-Grand-parent stock
(GGP), excluding sows second maternal and paternal
breeds
Sorghum is a source of concentrated, succulent and
coarse forage. Its grain is used for making the mixed
fodder and as the concentrated forage for swine, cows,
sheep, horses and poultry. Sweet sorghum is successfully
used for silage and haylage. Green chop of Sudan grass
is used as fresh food for domestic animals and it’s used
for making hay and silage. The nutritional value of the
fodder is the way to meet the animal needs in nutrients,
necessary for living. To determine the nutritional value
of the fodder, oat fodder units and energy fodder units or
exchange energy are used. At present the assessment of
nutritional value according to fodder units is being
revised, because it doesn’t give the true picture of the
value of fodder nutrition and animal needs in nutrients.
The general energetic nutritional value of fodder is
considered as contents of all organic substances, supplied
with fodder or with its energy. The nutritional value of
fodder is valued according to the characteristics of its
chemical composition, digestion of nutrients and general
(energetic) nutritional value. The purpose of the work is
to assess the nutritional value of fodder, obtained from
the best sorghum varieties, as the food for different kinds
of agricultural animals. Sorghum, used as fodder for
poultry possesses the largest nutritional value. Among
the grain sorghum varieties, the variety ‘Zernogradskoe
88’ has got the biggest value of fodder units. The green
chop of Sudan grass and green fodder for silage of sweet
sorghum possess the greatest nutritional value for swine.
The varieties of Sudan grass ‘Krasava’ and ‘Arkadiya’
and the variety of sweet sorghum ‘Listvenit’ are the best
varieties according to the contents of fodder units
