The effect of dietary supplementation with dry bakery yeast culture Saccharomyces cerevisiae in high concentrate diet (F:C=47:53) on milk yeald and rumen fermentation were studied on two groups primiparous lactaiting cows (8 cows per group) and four ruminally cannulated nonlactaiting cows on diet
F:C=25:75. Cows fed yeast during 67 days produced 1.24 kg/d and 1.66 kg/d natural and 4% fat corrected milk respectively more, than control cows. Milk protein and fat percentages were also higher. On diet with yeast ruminal concentration of lactate was lower and butirate+propionate was higher. The yeast
incrised rumen pH, decreased NH3 in rumen and urea in blood, decreased viscosity of rumen fluid
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
The history of department of genetic, breed¬ing and seed-growing is linked to develop¬ment of Kuban Agricultural Institute. The role of V.E. Borkovsky – the third chief of de¬partment a famous scientist on breeding of the castor-oil plant is showed
The technology production of microbiology preparation for protecting of plants from ill and insects was presented in this article. There are measures for improving the nutrient medium for growth of microorganisms
This article reviews hybrid analysis data on monogenic and digenic patterns of quantitative traits: plant height, panicle length and total number of spikelets
This article describes the results of laboratory experience on the impact of Ecoss enriched Biogumat on the productivity of radish varieties of Corundum in the conditions of artificial climate of Kuban state agrarian University. Sowing was made on November 24, 2014, in two replications. Processing was carried out by humic preparation with a content of humic substances 4 g/L. Humic substances are a special group of organic compounds, the origin of which is associated with the biochemical processes of decomposition and transformation of plant residues (leaves, roots, branches, trunks), animal remains, protein bodies of microorganisms In their composition we have detected humic acids, fulvic acids, salts of these acids, humates and fulvates and Hominy - durable connection of humic and fulvic acids from soil minerals. We have developed different ways of processing plants of radish humic preparation. The influence of this drug on the passage of the phenological stages of plant development was examined for radish and its morphometric characteristics and productivity, depending on processing methods
In this article the results of the research of quality characteristics of Russian and foreign rice varietieswere observed. A possibility of using the data in characterizing germplasm from the collection was discussed
Some derivatives of 3-aminothieno[2,3-b]pyridines,
N-pyrazolo[3,4-b]pyridinil-3-carboxamides and
substituted naphthalene-2-sulfonic amides were
synthesized for the search of the new winter wheat
growth regulators. The growth regulating activity of
the new compounds was studied and the substances
with high growth stimulating effect were found
The organic agriculture is an important issue for sustainable development and food quality production. For this reason we analyzed the data on land use in organic production and the volume of the market for organic products in Europe and Russia. The motivation of farmers and the driving factors for the transition to organic farming methods in developed countries and the role of subsidies have been shown. The analysis of the state of organic production in Germany has been carried out. In 2013, Germany reported 23484 organic farms, which represent 8.2% of agricultural production and the total cultivated area 1,045 Mio. ha. In organic production are involved 9 national associations with their own logos, integrated by 12250 farms (52.2%), and the remaining 11 234 biofarms (47.8%) use the EU-bio logo. Over the past years there has been observed a significant increase in organic livestock production; e.g. during 2007-2012 milk, poultry meat and eggs production were increased by 58.3, 60,6 and 108.7% respectively. Price of bio eggs in November 2014 was 55.6% higher than in free-range system and 100% higher than in floor housing system. Obviously, organic production is an efficient production system capable of ensuring the economic well-being of rural areas. For further expansion of this sector in Russia is necessary to develop the economic incentives, which encourage conversion from conventional, farming to organic production. Also, it is necessary to raise awareness of producers and consumers about the quality of organic products
A comparison of quantitative and qualitative performance of the selected clones of breeding of A.S. Yablokov and S.N. Bagaev has been made. At the same forest conditions, the clones are much higher than regular at reserves, the absolute completeness, the average heights and diameters of trees. Gigantic forms of P. tremula L. are resistant to infectious diseases, and at the fifth grade are characterized by good sanitary condition. We have also shown the economic feasibility of using of fast-growing clones in the genetic reserve for the organization of giant aspen of P. tremula L. plantation
