The article presents a research of reaction of seedlings of lettuce on light duration with sodium lamps when grown in a greenhouse. It was shown that in winter conditions of the Krasnodar Region the intensity of natural light to produce quality seedlings of lettuce is
insufficient and additional lighting has a significant influence on the morphology of lettuce seedlings
The results of the study of Robinia pseudoacacia state in mixed steppe forest shelter belts are given. The most productive variants of the mixture of woody-brush species for Robinia pseudoacacia are also listed
The analysis of qualitative indicators of Don selected soybean varieties aimed to determine a possibility of their usage in processing industry is carried out. An evaluation of chemical and organic leptical indicators of soybean seed quality and physical properties is made. Possible directions of Don selected soybean varieties usage in processing industry are determined
The article gives an overview of the results of studies on indigenous grape varieties of the Republic of Abkhazia and the identification of their agro-biological characteristics
In the article we have shown the results of the study of the treatment before laying hatching eggs for incubation, embryos at 6,12,18 days of incubation light bulbs CCB-15, CCB-30, OPL-150, DRT-400 at rates of embryonic development
In the article, we have shown the results of the study of treatment before laying hatching eggs for incubation, of embryos at 6, 12, 18 days of day-old chicks red laser LGN-104, "Matrix" and lamps DNESG-500, IC-220-250 on the performance of fetal viability, increments live weight of the embryos in the process of development
In this article results of research of quality characteristics of Russian and foreign rice varieties are observed. Possibility of using data in characterizing germplasm from collection is discussed
In the article we present the results of the study of the
relationship of reproductive qualities of sows
measured at the index selection
It was experimentally established, that the inclusion
dietary supplements, based on whey in feed mixtures
for broiler chickens improves digestibility and nutrient
digestibility of feed, which has a positive effect for
live weight of poultry
To improve the quality, safety and competitiveness
of the domestic raw materials of animal origin the
use of probiotics in the poultry industry is a priority
and promising direction of the development of
organic agriculture. One of the key problems of the
production of probiotics is to provide actively
stable preparations. Biocompatibility of the
indigenous microflora with probiotics, medical
form and individual range of antibacterial activity
of probiotics have a significant impact on the
introduction of probiotics in new habitat conditions
and its effectiveness. Consideration of these factors
can enhance the effectiveness of probiotics.
Currently, the available literature has insufficient
justification of certain doses of administration and
methods of using different probiotic preparations.
The materials present and summarize the results of
the research concerning the use of probiotics in the
poultry industry, based on the achievements of
Russian and foreign scientists. In addition, based
on the analysis of various sources of scientific
literature, we suggest ways to solve the problem of
probiotic therapy and give some recommendations
on the organization of the technological process of
selection and application of different probiotics in
poultryfeeding. Raw meat from poultry reared with
the use of probiotic preparations is safe, because
metabolites of probiotic microorganisms are not
accumulate in the body tissues. Researches of
biosynthesis regularities of probiotics were made at
the cellular level, including genetic aspects,
features of regulation of secretion, dependence on
the cultivation conditions, interaction with binding
sites on the cell surface, participation in the vital
activity of the population of individual cells. The
use of probiotics contributes to normalization of
the intestinal microflora, activation of protein
metabolism, productivity increase, reduction of
feed costs per unit of production and increasing of
poultry industry economic efficiency as a whole
