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
In the stationary multivariate experiment the effect of alternative technologies for cultivation of sugar beet for productivity and the economic efficiency of root crops production has been studied
The article describes the results of the complex feed additive based on sunflower husk, enriched with beer wort with the addition of pumpkin pulp. We have studied the chemical composition of sunflower husk, which is the secondary resource of the processing plant raw material, selected methods of enrichment of this raw material with the help of fungi Trichoderma harzianum. Cellulolytic enzyme preparations on the basis of fungi of the genus Trichoderma for use in agriculture and animal feed production is often obtained when the surface method of cultivation. These drugs are cheap and contain a significant number of related hydrolytic enzymes, 29 such as amylase, protease, pectinase and hemicellulase, which are also important and valuable to the consumer. As a vitamin component of the feed additive we have selected a pumpkin pulp, which is a valuable feed for livestock and poultry is a source of carotene, fat and nitrogenous substances. We have also developed elements of technology for complex feed additive. We have created a comprehensive feed additive which can be used in the composition of diets in the feeding of farm animals and poultry
One of the prospect directions in new sunflower
hybrid development is cold resistance breeding in
the emergency stage. Sunflower hybrids with
uniform emergency and high rate growth under the
low temperature conditions could allow to
introduce sunflower in the new regions of our
country and so to increase sunflower acreage. The
aim of our work was to screen all sunflower
available samples for growth rate under the low
temperature and to select the best lines and initial
material for future breeding. 140 sunflower lines of
VNIIMK breeding and hybrid populations on their
base were used as a material. Seeds of every sample
were incubated during the 10 days in the thermostat
under 100 С. Seed germination was evaluated for
the each sample along with the seedling size. As a
result the most prospective samples were selected
for the future breeding work. On the second stage
of the experiment one selected population was
evaluated on the Breeding station of Vavilov’s AllRussian
Research Institute of Plant Industry in the
city of Pushkin (Leningrad region). Seeds from the
best plants were obtained in this place and will be
used for the new lines development.
So the effectiveness of selection of sunflower
samples for growth rate under the low temperature
was verified and this method could be used to
introduce sunflower in the new regions of our
country with more severe climatic conditions
The results of application of specially selected amino acids complex on the basis of alpha-amino-gamma-methylmercaptobutyric acid to protect sunflower plants from bacteriosis, broomrape and weeds have been represented in the article
The obtaining of high-quality meat is impossible
without providing of full value feeding of agricultural
animals in the combination with the maintenance of
conditions of their feeding. In farms of the Krasnodar
region the seeding of forages with molds varies from
103 to 107 КОЕ in 1 gm of forage. There was
conducted the study of influence of feeding of
animals with mold mixed fodders on the seeding with
microscopic fungus of tissues of inner organs. There
was carried out the slaughter with the aim of study of
meat quality, immune hematological large part of
intestines. There were selected the samples of meat
and inner organs on the seeding with microscopic
fungus. There was determined that in tissues of inner
organs of animals which during 4 months were on the
ration including the mixed fodder with general
seeding with mold fungus 105 -106 КОЕ in 1 gm of
forage, there were found the spores of molds. Also
there was determined the intensity of animals’ growth
of first and second groups reliably did not vary
(p>0,5). There were worked out the ways of
improvement of sanitary condition of fodders by the
means of introduction of the salts of microelements
into rations such as bluestone and ferrous sulfate with
the addition of probiotics KM3(cultured milk
fermentation including Streptococcus lactis,
Lactobacillus acidofilum) influencing the growth of
pigs, the condition of their health and the quality of
meat raw at the using of fodders dirty with
micromycets. The consumption of fodders attacking
with microscopic fungus with the addition KM3
showed that the lacto- and bifidus bacteria KM3
suppressed the development the pathogenic
microflora of gastrointestinal tract of pigs. There were determined the optimal doses of the
introduction of detoxicants in fodders affected with
molds of storage. The positive effect in average
amounted 8%

The increasing consumption of forest resources causes
a greater anthropogenic impact on forest ecosystems
and leads to a negative impact on both biodiversity and
the environment as a whole. In this article, the
sustainability of forest phytocenosises of southeast of
Western Siberia is assessed using the example of
Tomsk region. The analysis of the status and dynamics
of the forests of Tomsk region has been assessed. The
main factors negatively affecting the biodiversity of
forests of Tomsk region were analyzed. The forests
cover extensive areas; therefore, the studies were
carried out based on the data from the State Forestry
Register of the Russian Federation for the period from
2008 to 2015. According to the results of the study, the
sustainability of forest phytocenosises has increased
significantly in recent years, which can be explained
by its strengthened ability to maintain the current state
under the influence of external factors. This work
considers such causes of damage and death of forest
plantations as pests, forest diseases, unfavorable soil
and climate impacts, forest fires, as these are the main
and most massive phenomena that cause the greatest
damage to forest. It is possible to see the dynamics of
damage and death of forest plantations on the figures
presented in the article
