Methodological and productive and economic aspects of the developed system of the organization and management of harvest-procuring of a grain yield and sugar beet, and a problem of interdepartmental interaction are analyzed. The innovative approach to increase of efficiency of harvest-procuring in plant growing in modern conditions is offered
Acidic properties of the mineral matrix of meadow
chernozem and meadow-boggy soils of Krasnodar
region are characterized by a total adsorption capacity
of ammonia in the range of 32-61 µmol / g. The lowest
acidity of the matrix was observed under conditions of
permanent rice cultivation for 80 years (32-
33 µmol NH3/g). The mineral matrix of rice soils
depends on the meliorative state and the granulometric
composition of these soils. At low fields of meadowboggy
soils, heavier in granulometric composition, the
total acidity of the mineral matrix is 51-
53 µmol NH3/g on high checks of lighter meadow
chernozem soils – 34-45 µmol NH3/g. In the upper
soil, with a less acidic matrix, the Fe3+ content
increases and the amount of Fe2+ decreases. The
reverse pattern is found in the lower soil with more
pronounced acidic properties of the matrix. A
proportional relationship between the humus content
and the acidic properties of the mineral matrix is
found. The highest yield of rice is formed on meadow
chernozem soils with a less acidic mineral matrix
Results of studying of meat efficiency of bull-calves Kazakh white-headed, Kalmyk and Simmental breeds.
Features of formation of meat qualities of bull-calves in the conditions of the Bottom Volga region are considered
Experimental studies were carried out on the breeding
farms of "Russian pork" in Millerovo district of the
Rostov region on purebred and crossbred animals
derived from crosses of pigs and the Don steppe types
of meat, breeds of Landrace and Pietrain. The Don
type of meat was used in the experiments as a control.
When crossing, the DM-1 pigs were used as the parent
form, and CT as a father to give twin breed hybrids
DM-1 x ST. The recent delivery of boars of Landrace
and Pietrain breeds allowed to receive twin breed
hybrids of genotypes of CT × L and DM-1 × P
The article presents the study of carcass and meat quality of ST and DM-1 pig breeds, and the hybrids obtained with the participation of Landrace and Pietrain breeds. Crossbred gilts significantly superiors to counterparts in all parameters of meat performance
In the article, the influence of "Tykvoglilakt" biologically active additive on productivity of pigs and food meat value got from thoroughbred and mixed animals is presented
The article presents the results of the control slaughter of purebred and crossbred lambs. It was found that the index of compactness and the main killer performance superiority had two or three breed lambs obtained from crosses involving sheep southern meat breed. The experimental animals were taken measurements of carcasses, which give a fairly complete and objective view of the differences in the length of the torso, hips, mascara and hip girth. There are specific differences in the yield of the most valuable cuts of the first grade the rams depending on the origin. The superiority of crossbred calves over the control for this indicator amounted to 16.4 and 33.4%. The chemical composition of the meat fine-wool lambs contained more moisture and less fat and less calories than meat crossbred animals. Increasing the hybrids values of the protein quality index indicates an increase in meat share of muscle proteins and the reduction of connective tissue, and consequently, improving the quality of the raw meat. Animals obtained by crossing, have wide and deep body, well-developed muscles of the thighs, the best quality characteristics of meat productivity
Increasing the yield of crops is a global challenge posed by the scientists from all over the world. To achieve this goal, we use various methods such as: engineering, agro-technical, agronomic, chemical, physico-chemical and so on. We conducted a theoretical study, which showed that the use of physical and chemical methods of treating seed before sowing has a positive effect on the growth processes of seeds. One of such methods is an ozone treatment, which has established itself as a quality growth stimulator of agricultural plants. But despite numerous studies there is no clear description of the mechanism of ozone effects on seeds. In this article, based on our theoretical study, we have presented a material that allows revealing the positive effects of ozone exposure to the seed. To confirm these theoretical results, we have decided to conduct a pilot study. In connection with what, in this article we have included the materials containing information on laboratory equipment and methods of the experiment. We have also presented measuring equipment and methods of iodine-metric method for determining the concentration of ozone in the ozone-air mixture, exact conformance with calibration gas analyzer which will allow to obtain reliable data on the dose effects of ozone on the grain
The article contains data of reacclimatization of mar-mots (Marmota bobak Muller) in Lipetsk region. Pos-sibility of application of artificial holes for fixation of colonies of animals in certain terrain is considered. Influence of a grazing of the shallow cattle on locali-ties of marmots is investigated. Degree of success of measures for reacclimatization of marmot badgers is defined
In the experimental work, we studied the effect of the
inulin prebiotic on the growth, development and
efficiency of growing broiler chickens of the Isa cross.
In accordance with the scheme of the experiment, the
first control group was fed a complete feed (CF) by
periods of growth. In the second group, inulin was
added to the CF for the first 21 days of growth. In the
third group prebiotic was added to the CF at the same
rate throughout the whole period of rearing the chicks
(42 days). In the second and third groups, we found the
tendency to increase the intensity of growth rate in
poultry by 1.6 and 3.0%, respectively, compared with
the control. Feed costs for weight gain were decreased
by 2.1-2.7%. In the chime of the blind processes of the
intestine of the chickens of 2-3 experimental groups it
was found the reduction of staphylococci and
enterococci CFU, while similar to the control group
lactobacilli CFU. The muscle tissue in the chickens of
experimental groups had greater protein content. The
optimal range of indicators is the use of inulin for the
first 21 days of rearing poultry. Because of the
production audit, an increase in live weight of chickens
was found, in the experimental group by 2.7% (p ≤
0.05), a decrease of feed costs by 7.5%, increase of the
survival rate of poultry by 2.0% and profitability by
3.1%
