In 2010-2012, in a field experiment, the research on the effect of fertilizers on physic-chemical, agricultural chemical and biological parameters of soil, as well as their impact on the dynamics of the content of major nutrients in soybean plants and its yield was conducted
Distinctions of soil under a winter wheat after a winter wheat and common sainfoin in provision of moisture and feed elements are revealed. Influence of autumn application of complete fertilizer and spring nitric dosage compensations on productivity and quality of a winter wheat are established; dependence of fertilizers’ effect from nitrate nitrogen contents in the soil is shown. Optimum dozes combinations on both predecessors are found
The article discusses the development of piglets in utero using irradiation lamps IK -250 and BUV – 15
The article presents the indicators of the protective afforestation in the Central Chernozem region, particularly the growth of various tree species in pure and mixed composition of forest belts, influence of field protection plantings on environmental conditions of surrounding agricultural landscapes
The article presents the indicators of the protective afforestation in Voronezh region, biometric growth index, agricultural and environmental impact of forest belts, efficiency of agro territories
Basic aim of institute’s breeding is to keep, renew and
increase selection and genetic resources of Nicotiana
tabacum. Final stages of this work are competitive and
state sort testing procedures. Their results are base for
zoning new sorts. In the article, the results on testing 8
new tobacco sorts of Trapezond and Ostrolist sort type
are presented. Testing on experimental field situated in
Severskii district of the Krasnodar region lasted for
five years. For this purpose, phenological observations,
biometric and technological properties measuring,
plant productivity and dried tobacco quality
assessments and other operations were carried. As the
result, Trapezond 25, Ostrolist 360 and Sheptalskii 63
sorts may be recommended for zoning and utilizing in
industry. Trapezond 25 and Sheptalskii 63 are sorts
with high productivity, high quality of dried tobacco
and good curing properties. Ostrolist 360 when earlymiddle
maturing keeps high productivity and quality of
cured tobacco. Other sorts: Trapezond 115, Ostrolist
311, Ostrolist 149, Ostrolist 90, Krupnolistniy 22 can
be initial material for further selection
There were presented the results of bumblebee application for obtaining of hybrid seeds of tomatoes
The review of the studying digestibility and assimilation of broilers diet nutrients under the influence of multienzyme composition Ronozim VP, phospholipid preparation of lecithin and probiotic Bifidum for agricultural animals is given in this article. The most important results of the effective use of mixture of biologically active substances included in diets are also discussed
The researches were carried out with the support of the Federal state budget establishment "The development assistance fund of small forms enterprises in scientific-technical sphere" (Fund for the innovation promotion), contract number 0019671. The fodder additive «Nutovit» in growing chickens feeding application enriched mixed fodder for farm poultry with protein and especially with the amino acid such as lysine. Scientific-economic experiment was carried out at the poultry-farm enterprise of the Volgograd region in 2015-2016. 4 growing chicken groups with 54 heads in each group were selected for the experiment. The growing chickens were selected according to the cross, age, living body weight, health status. The difference in experimental poultries feeding was that in the experimental groups the sunflower oil cake in the feed mixture was replaced by fodder additive "Nutovit". It was established, that the essential amino acids availability and the saturation of fodder additives with vitamins influence positively on: young chickens live weight and average daily growth, the live weight to 120-days age in the second experimental group amounted to 1657 g, and average daily growth was to 12.46 g, which is higher compared to the control group by 4.48 % at 100% poultry livability; blood morphological and biochemical composition: formed elements of blood, namely erythrocytes, in the experimental groups young chickens blood were more in 0.02 to 0.05×1012/l compared with the control one. The researches established that blood leukocytes reduction in growing chickens of the experimental group was little, in 0.04, 0.09, 0.08 ×109 l. Calcium content in growing chickens blood in the control group was 2.6 mmol/L. The experimental group surpassed the control on 0.14-0.21 mmol/L. The phosphorus content in chickens blood in the experimental groups exceeded the control one by 0.08-0.24 mmol/l. In addition, the feeding cost reduction was established due to the fodder additive "Nutovit" use
The right balance of essential amino acids and protein is the main condition for the optimization of weight gain, feed conversion and high profits. In VGC "Megamix" the quality of different types of raw full-fat soy, wheat, corn, meat and bone meal and fish was assessed on the content of amino acids on the IR analyzer of FOSSNIR Systems company. Amino acid content in the feed does not always match the average standards of reference. So in the reference data content of methionine, threonine and phenylalanine in wheat, indicated 0.23%, 0.43% and 0.64% respectively, and studied in the laboratory of VGC "Megamix", respectively, 0.24%, 0.45% and 0 73%, that is 0.01%, 0.02% and 0.09% higher of tabular values. The lysine content of the wheat to be investigated in a laboratory and provided in the averaged data was on the same level. Thus, the calculation of the recipes should be carried out taking into account not tabulated values but the actual, which will reduce the so-called "safety stock" to get food of consistent quality and reduce the cost of the cost of animal feed, which in turn affects the economic efficiency of livestock production
