EVALUATION OF FEED REPLACEMENT EFFICIENCY AT GROWING CROSS COBB-500 BROILERS

Posted in 2018, Issue №12(78) December 2018, VETERINARY SCIENCE | 0 comments

Broiler production is the most important highly efficient sector of the poultry industry, which allows to obtain cost-effective meat products, its production requires compound feed which provides high energy value and protein in its raw form. Research methods: observation and experiment; analysis and synthesis; experience; comparison; methods of variational statistical analysis. As experimental data shows, the partial replacement of compound feed, which contains components of animal origin – meat and fish meal, soybean meal in the final period of time when growing the experimental group of broilers of the Cobb-500 cross, leads to an improvement in the economic efficiency of indicators production.

СOMMUNICATION OF PARAMETERS OF HATCHING EGGS WITH HATCHABILITY AND SEX DETERMINATION OF BIRDS

Posted in 2018, BIOLOGY, Issue №12(78) December 2018 | 0 comments

The purpose of this research was to study of effect of periods of storage of eggs before incubation, their shape, mass and density on hatchability, and sex ratio. The increaseof hatchability and early detection of sex determination of young birds create opportunitiesfor differentiation of their keeping and feeding that will help to reduce the cost of poultry products and increase of industry profitability. Interconnection of hatchability and by the studied parameter. Sex of pauls has been determined by Japanese method.According to the results of study of incubation of turkeys eggs have been found that sue to the elongation of shelf life from 7 to 9 days, there was a decrease of hatching of young turkeys from 72.2% to 68.2%; geese eggs with a shelf life from 7-14 days – from 64.6% to 55.2% with ratio change in hatching of females/males from 1.00/.02 to 1.00/1.26 up to 1.00/1.03 and 1.00/1.21 respectively. Hatchability of turkeys’ eggs with weight 80-90 g was 75.4%, geese eggs with weight 140-150 g – 66.7%. Upon gaining in weight of incubated eggs of turkeys from 80 to 90 g and ratio of female/male has been increased from 1.00/0.96 to 1.00/1.11 and geese from 140 to 150 g or more to 1.00/1.06 to 1.00/1.13. When the index of shape of eggs is reduced, the hatching of young birds decreased and density of males increased. The decrease in density also reduced the hatching of young birds, but does not reflect on sex ratio.

INFLUENCE OF ADVANCED GLYCATION END PRODUCTS ON CELLULAR PROCESSES

Posted in 2018, BIOLOGY, Issue №12(78) December 2018, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

Advanced Glycation End products or AGEs are formed as the result of non-enzymatic interaction of proteins with carbohydrates and belong to the group of modified amino acid residues that can slowly accumulate in the body during the normal process of aging. In addition to endogenous AGEs, these toxic compounds appear in the human body due to the consumption of food that has been heat treated or subjected to long-term storage, due to active and passive smoking. AGEs can cause the onset and progression of complications of diabetes, and become the basis of the pathophysiology of many other diseases including cardiovascular and neurodegenerative ones. Both exogenous and endogenous AGEs play a significant role in the development of the inflammatory response in the human body. The proposed review examines the structure and functions of the main AGEs receptors and the signaling pathways they activate, as well as some of the biological effects of this activation.

MAIN FEATURES OF ERYTHROCYTES MORPHOLOGY IN PERSONS DEAD OF HYPOTHERMIA

Posted in 2018, Issue №12(78) December 2018, MEDICINE | 0 comments

This paper presents the results of the study of erythrocytes morphology of the persons dead of hypothermia under the temperature conditions of Yakutia (below -40 °C) with the help of scanning electron microscopy (SEM). Characteristic features of the erythrocyte morphology were revealed, and experimental data were compared before and after prosection. Before prosection, discocytes prevailed and only 15% were altered erythrocytes, that is – echinocytes. After prosection, the percentage of echinocytes more than doubled. The results of the study can be used in the formation of fundamental ideas about cellular changes in critical states and possible mechanisms for the recovery of cells and their functional properties.

Posted in 2018, CHEMISTRY, Issue №12(78) December 2018 | 0 comments

A nonmagnetic narrow fraction of dispersed particles with an average diameter of 2, 3, 6 and 10 microns from the fly ash was isolated from dust-like combustion of Ekibastuz coal by the method of aerodynamic classification followed by magnetic separation. It is established that with an increase in the size of fractions the bulk density monotonously increases from 0.90 to 1.07 g/cm3. The main components of the chemical composition of the dispersed narrow fractions are SiO2 – 65-70 wt. % and Al2O3 – 23-28 wt. %. The phase composition includes 64-69 wt. % glass phase, 17-21 wt. % phase of mullite, 10-18 wt. % of quartz. The particle size distributions are characterized by the following values d50 – 1.9; 2.3; 5.1; 9.2 microns and d90 – 4.5; 5.7; 11.4 and 16.7 microns, respectively. The main morphological types of particles are microspheres with a non-porous smooth surface and microspheres with a porous shell; as the size of fractions increases, the amount of microspheres with a porous shell increases.

Posted in 2018, CHEMISTRY, Issue №12(78) December 2018 | 0 comments

The housefly Musca domestica L is a synanthropic insect and is very dangerous to human health and pets. Sex pheromones of insects are actively used to develop and create effective means of protection. The article studies non-trivial approaches of fine organic synthesis, which allows reducing the number of stages in the preparation of pheromones. A three-stage approach to the synthesis of cis-9-tricozenes, the sex pheromone of the housefly Musca domestica L, was tested [1, P. 2792]. Synthesis of (quinolin-8-yl) -cis-9-octadecenoate is carried out and its physicochemical properties are studied.
