This article presents the results of the study of the relationship of reproductive qualities of breeding boars and sows with their level of natural resistance, as as-sessed by resistance index
The optimal rations have been found. We have
conducted a research on the assessment of meat
productivity, biochemical blood tests. The chemical
composition of blood and meat has been found. We
have empirically chosen a content area for both chicks
and adults of black African ostriches. The article
shows a selection of optimal rations for feeding of
ostriches; we have also determined the live weight of
ostriches in groups, keeping the chicks safe in groups,
hematological studies of ostriches blood, the chemical
composition of the meat, the efficiency of premixes of
Vitafel S
The article describes the evaluation of reproductive,
fattening and meat qualities of pigs of purebred large
white breed (KB), crossbred ewes, derived from
crosses KB sows with boars of steppe type (ST) CM-1
and three-pedigree animals, obtained by crossing
crossbred ewes KB x ST with imported boars of
specialized meat breeds, such as Landrace (L) Duroc
(D) and pietrain (P). We have studied qualities such as
prolificacy, milk yield, live weight of the nest, the
average weight of one Piglet, the safety of the
offspring to weaning, maturity, which is closely
associated with average daily gain in live weight, meat
content of carcasses, their linear dimensions, meat
productivity, the amount of kidney fat, weight of
carcasses of animals of the experimental groups,
carcass yield
In the present article we have building and comparison of linear regression and neural network based mathematical models of raw meat organoleptic evaluation from the main physical, chemical, functional and technological parameters performed
Limited resource of irrigation water in the South of
Russia is a particularly actual task in the production
of moisture-loving crops, such as rice. To solve the
problem of rational use of water when watering is not
possible without the organization of an automated
water distribution. As it was shown by the analysis of
tools and technologies of regulation of water supply,
the most promising, form tested and used, can be tape
regulators of flow and water level. They have a
simple construction diagram, unpretentious in
operation. However, we have identified a fault –
unregulated leaking, not fully covered through the
bore, which in turn increases the uncontrolled
consumption of irrigation water. To solve this
problem we propose a number of designs, protected
by patents of the Russian Federation, having special
fixture to ensure unauthorized leaks, even in a state
almost close to the fully closed opening expiration
from the regulator. The article comprehensively
considers hydraulic studies of controller initially,
without any additions that contribute to the problem
of eliminating leakage. The proposed study with the
analysis of the distribution of velocities and pressures
in the design of belt regulator, will allow you to have
the basic reference model against which it will be
possible to analyze the degree of influence of
constructive-technological changes at the work the
newly developed devices. For this, we modeled tape
controller in the software package FreeCАD version
0.15, when using SAE - system FlowVision. The task
of modeling water flow were solved in flat statement,
including the moment of full closing of the belt
passage opening of the regulator. For plotting surfaces, lines, levels and cross-section response
functions, we used a software package wxMaxima.
The results obtained allowed a comprehensive
analysis of the work tape of the locking device,
hydraulically actuated device in all modes of the
major factors and, in the future, will help to address
the issue of studying the impact of introduced
technological changes in the design of controllers
This article shows the lines for the processing of manure. Besides, the equipment which is necessary for the realization of the process is defined
In this article chemical and technical characteristics questions of vine materials, received from protoclones of grapes of Saperavi grade - one of the basic classical grades of grapes selected in "Pobeda" Joint-Stock Company are taken up. Samples of grapes have been used for preparation of red table wines by mash fermentation on septum in workshop of micro winemaking of The North Caucasian zone scientific research institute of gardening and wine growing. They have not given vine materials identical on physical and chemical and organoleptical features. Samples with low productivity essentially differed on organoleptical qualities from other samples and had the highest sampling estimations that allows to take measures on loading regulation on a grape bush and correct quality of wine in further by means of methods of agricultural technics. For making high-quality table red vine materials it is recommended to use apple-lactic fermentation by means of oxygen-eating bacteria
We review the critical ratio of shares of domestic and
imported sunflower hybrids in the region and the trend
of displacement of domestic hybrids in the Kuban region,
yields and gross harvests culture. The article reveals
a negative trend for the full displacement of domestic
hybrid seeds from the market in the Russian
Federation
The article analyzes the development of animal husbandry, the effectiveness of land use in the various categories of farms in value and real terms, the reserves of growth of production of animal husbandry products
It was being done to established difference by sus¬cep-tibility rate of plant pathological bacteria Pse¬udo¬monas syringae spp. It was clearly recog¬nize, that are cultivating varieties Zimtra and Nota were the most susceptibility, and, Krasnodarskaya 99, Fortuna, Pamyat, Batko, Tania were low resis¬tance. Usage for sowing high affected seeds by Pseudo¬monas syringae spp. Leads to decreasing its germi¬nation and biometrical parameters of young growth.
