Modern pig farming is a leading global livestock
industry, but the organization of adequate balanced
feeding is actual for the industry. Digestibility of
metabolizable energy of feed depends on various
factors, including the content of non-starch
polysaccharides, which have a negative effect on the
digestibility of key nutrients of the feed, lead to a
decrease in growth rate and conversion efficiency of
nutrients. Enzyme preparations which composition
generally includes Xylanase, cellulase, β-glucanase
activities, may avoid the negative impact of non-starch
polysaccharides. Today's promising preparation that
combines the functions of two feed additives - feed
enzyme and probiotic, is an enzyme preparation
Cellobacterin that, due to the particular organization of
the enzyme complex, increases the digestibility of
barley grain and effectively effects on sunflower meal.
As a probiotic preparation it inhibits the development
of pathogenic microorganisms and promotes the
formation of beneficial microflora in the digestive
tract. The introduction of Cellobacterin enzyme
preparation into the compound feed with a high
content of barley grain and sunflower meal increases
the body weight of young pigs by 4.8% and reduces
the cost of feed per 1 kg of live weight gain. The
results of hematological studies found no significant
deviations from the physiological norm in the
morphological picture of the blood in experimental
animals. The group, where Cellobacterin was added,
showed higher vitamin A content by 2.8% as
compared to the control, while vitamin E is found in
both groups on the same level. Based on the results of
the research to improve the productivity and growth
rate in compound feed based on barley and sunflower
meal with higher fiber content, it is recommended to
include in the compound feed Cellobacterin enzyme
preparation at the rate of 1 kg per 1 ton of feed
There was shown the possibility of assessment of hybrid apple-tree posterity on relation to the drought with the help of mathematical modeling. There was worked out the mathematical model of prognosis character on assessment of apple-tree genotypes to the given stressor. There were offered ways of optimization of hybrid posterity selection conducting in modern selection programs
Results of morphobiological analysis of productivity and adaptivity of corn collections samples of ARRI named by N.I. Vavilov to the concrete ecological
Conditions. More than 60 samples ( varieties, hybrids, self-pollinating lines) concerning to the different
Subspecies are casted.
The article reviews the results of studies of adaptive properties of the hybrid corn of different groups of maturity at the background of anthropogenic factors. It discusses the practical application of research results in order to maximize grain yields from 1 ha, environmentally friendly products (including at cultivation of corn on the protected areas), economically viable crop with maximum return on investment, as well as the possibility of extensive corn cultivation technology with limited material resources-money producers
The article presents the analysis of the experimental data obtained during testing varieties of soft winter wheat. Such characteristics as plasticity, stability, homeostaticity, yielding capacity and bakery qualities are discussed

Newest aromatic white berry wine grape variety Agapi was breeded by hybridization at the Athens Institute of Viticulture (Likovrisi, Greece) by professors P.Zamanidi, L.Troshin and P.Radchevskiy in 2006 by crossing the Greek varieties Afiri white with central European variety Traminer pink. Strong growth of shoots (2,1-3,0 m). Level of ripening vines is very high: over the entire length except the top. Length of production period 146-155 days. Productivity is very high: 25-30 t / ha. Average weight of cluster 300 g. Characterized by a high resistance to cold, drought and increased resistance to fungal diseases compared to varieties of Vitis vinifera L. Flower is androgynous. Bunch is medium, conical, medium density. Berry is medium, short elliptical or spherical, greenish-yellow in color, with a thick waxy coating. Cuticle of medium thickness, dense, and durable. Pulp and juice are with pronounced varietal flavor, similar to the aroma of Traminer pink. The sugar content is very high, more than 24%. Clusters of Agapi variety regardless of autumn weather conditions persist for a long time in the bushes. Variety intended for the manufacturing dry white wines of excellent grade and high-quality sparkling wines, dessert and sweet wines; suitable for production of high quality fragrant juices
Barley is one of the important fodder crops. In modern
Russia barley is sown throughout the farming areas.
The effectiveness of barley cultivation in some years is
reduced due to the infestation with helminthosporiosis.
Net blotch of barley Drechslera teres is a widespread
and highly destructive disease in the world including
Russia. In recent years the disease has been
progressing in all grain-producing countries. Yield
reduction due to the strong development of the blotch
can reach up to 45%. Most cultivated barley varieties
are susceptible to Drechslera teres. Нelminthosporiosis
are characterized by greater variability and rapid
adaptation to new varieties of host plants. In order to
solve successfully the problem of barley immunity to
net blotch it’s necessary to conduct genetics and
population studies of the Hordeum vulgare -
Drechslera teres pathosystem
