SYNCHRONIZATION OF THE HATCHING AT THE ARTIFICIAL INCUBATION
06.02.00 Veterinary and Husbandry
DescriptionThe embryo passes a number of the stages caused by high-quality structural changes in development and following them growth periods. The periods of change of development for the periods of growth are critical and are most sensitive to influence of external factors. The developed differentiated mode provides sharp temperature increase of incubation in the critical periods of development of an embryo. High temperature at separate stages of an incubation has displaced metabolic processes of the developing embryo towards lipidic exchange, at the same time the cholesterol indicator in blood of skilled chickens has grown more than twice, and level alkaline phosphatase by 2,5 times. Synchronization of the hatching was reached due to reduction of the periods embryonic and output on about 10-12 of hours. Operating an embryogenesis in the period of incubation there is an opportunity to influence the level of productional processes of chickens during the post-embryonic period, average daily gains of live weight at cultivation of broilers increase on average by 5-7%

COMPARATIVE EVALUATION OF CANNED AND NATURAL FOOD IN THE DIET OF PREGNANT AND LACTATING DOGS
06.02.00 Veterinary and Husbandry
DescriptionThe article provides evidence of the high social value of dogs as the most common among pets. We present the results of determining the main causes of illness in dogs and the role of nutrition in the formation of this indicator: the share of diseases of the digestive system and various metabolic diseases accounted for more than 70 % of the total of substantiated cases to the clinic. We have estimated chemical composition of feed premium, industrial production, assessed according to the standards of the National research Council (NRC) for dogs of small breeds in the period of pregnancy and nursing puppies. We have established the feed requirements of pregnant and lactating bitches (Yorkshire Terrier) for key nutrients and bioactive substances. Recipe is made up and we manufactured food standards NRC from natural ingredients; conducted a scientific experiment to assess the impact of both feed on milk productivity indices of mothers and indicators of growing puppies (body weight at birth, weight gain). We have convincingly demonstrated the advantage of using natural food as from a physiological and economic perspective, as it is accompanied by a marked reduction in the cost of the dog and of the cost of the puppies

MECHANIZATION PRODUCTION PROCESSES STRATEGY OF HIGH QUALITY WHEAT GRAIN +)
05.20.00 Processes and machines of agroengineering systems
DescriptionThe production system analysis of high-quality winter wheat grain was done and the problem solution methods based on mechanization production processes strategy through a new generation of equipment and innovative improvement of machine technologies were outlined. Deterioration of grain quality indicators in the country was marked: the proportion of strong wheat is not more than 0.5% of commodity grain resources, and about 80% of exportable parties is wheat of 4...5 classes. Thus, it is possible due to the process mechanization to raise the grain quality. A well-known method of functional-cost analysis was applied to ground machine technological operations, which are the first to be developed in order to improve the wheat quality in the entire technological system, the demand for which is reduced abroad. The basic technological principles of production of high-quality grain were designed. They have three subsystems: the structure of the wheat varieties for the agricultural producer, the previous crops for wheat, features of cultivation technology of valuable varieties on the basis of intelligent manufacturing systems machines. The mechanization of high quality grain production processes was proposed. It can provide engine technology improvement due to rational composition machine-tractor units of new generation. They allow abandoning the outdated usual items of machinery used in their system and dramatically raise labor productivity due to the combination of operations, quality of work, yield and reduce costs. The features of mechanization on harvesting and post-harvest grain refinement are reflected with the aim of improving its quality. Applied to various forms of management, intellectual grain sorting means of mechanization recommended, which contribute to an increase in wheat quality. The impact of "neveika" technology with the completion of a heap at the stationary place on the grain quality improvement was marked

05.20.00 Processes and machines of agroengineering systems
DescriptionProcesses and machines of Agro-engineering systems with good reason can be considered as complex multiparameter natural and technical systems. In these systems there are numerous and diverse physical, chemical and biological processes. On the one hand, these processes have a significant impact on the performance of these systems. On the other hand, they are extremely difficult to describe in the form of meaningful analytical models based on equations. As a result, the development of meaningful analytical models is associated with a large number of simplifying assumptions that reduce the validity of these models. However, mathematical modeling of processes and machines of Agro-engineering systems is necessary for the development of both their designs and application technologies. Thus, there is a problem that is proposed to be solved with the use of phenomenological information and cognitive models. These models are based on the theory of information and describe the simulated system purely externally as a "black box", but it is meaningful. System-cognitive models can be built directly on the basis of empirical data using the intellectual system called "Eidos". This is done by model technology and methodology and is much less time-consuming and much faster than the development of meaningful analytical models. On the other hand, phenomenological system-cognitive models can be sufficient to determine rational design features and parameters of processes and machines of Agro-engineering systems. In addition, such phenomenological models can be considered as a first step in the development of meaningful analytical models. A numerical example is given

DescriptionIn the article, there were shown the experimental researches describing the influence of parameters of electrical ozonization of the premises of egg storehouse at concentration of ozone in 20 mg/m3 on survival of following stimulants: S. aureus, S. choleraesuis, P. vulgaris, E. coli. There was determined that ozone has an ability to detain the growth of fungi on biological substrates as well as it slows down the process of mould appearance on egg shell surface even at 90% of relative moisture. The aim of scientific experiment is obtaining of regression models of influence of parameters of electrical ozonization on main sanitary-model microorganisms contaminating the shell of incubation eggs. To assess the effectiveness of ozonization there was adopted the parameter of survival for four main pathogenic microbiological test-objects which predominate on egg shells. The correlation and regression analysis of factors and determination of value of equation coefficients there were conducted using the program STATISTICA 6.1. The correlation analysis was made by the method of Pierson. Approximation was obtained by the method of polynomial. On the results of researches there was determined that the least survival of present test-bacteria at concentration of ozone in 20 mg/m3 is achieved at exposition 84 minutes. So, the rational time the electrical technological process of ozonization of egg storehouse of poultry factories presents the sum of obtained exposition and time of regulation
