06.02.00 Veterinary and Husbandry
DescriptionThe article considers the application of Eidos intellectual technologies for implementation of developed veterinary and medical diagnostics statistical tests without programming in the convenient form for the individual and mass testing, the analysis of the results and development of the individual and group recommendations. It is possible to merge several tests in one supertest

05.20.00 Processes and machines of agroengineering systems
DescriptionThe issue of resource saving in the process of preparation of feed mixtures of multifunctional mobile units on livestock operations shows the need for further qualitative research in the preparation of feed for feeding with the goal of full realization of the genetic potential of animals. Modern cars often do not meet the above requirements that require new solutions. The theoretical study of grinding process feed stem proposed biplane segments allow you to define conditions and to identify the main factors affecting the studied process, and subsequently reduce their impact on the operation of the machine as a whole

THEORETICAL JUSTIFICATION OF PA-RAMETERS OF A PLOW CYLINDRICAL FIELD BOARD
05.20.00 Processes and machines of agroengineering systems
DescriptionThe article considers the dependencies of the constructive parameters of a field board in the form of a cylindrical drum on the physical and mechanical properties of the soil. Expressions have been obtained for calculating the radius of the cylinder, as well as the size of the arm for installing the cylinder relative to the sock of the field board. The article also shows the limits of using field boards data on the bodies of plows

PROCESS OPTIMIZATION OF POULTRY BIOLOGICAL WASTE TRANSPORTATION
05.20.00 Processes and machines of agroengineering systems
DescriptionPressure mode compressed-air installation use that allows transfer of biological poultry wastes was based on the investigation of agricultural cargo hauling equipment. The installation includes a compressor with a receiver, a conduit, a cork forming section, a valve and a reservoir. As a result of using the installation the energy intensity and consumption of the process are reduced during the transportation of the material, labor costs are reduced and the issue of environmental protection is resolved. To optimize the working process of the compressed-air installation, the volume of the blow-off boiler, the length and diameter of the pipeline were determined. It was established that the most important technological parameter of the installation, which is productivity, depends on its design parameters and physical and mechanical properties of the initial material. The determining influence on the performance is the air pressure and the speed of product movement. The required air pressure is regulated by the compressor, and the speed of transportation is due to the design parameters of the installation and the physical and mechanical properties of the material. These aspects are taken into account in this project for process optimization of the poultry biological waste transportation

DYNAMICS OF EGG PRODUCTION IN CHICKENS OF VARIOUS BREEDS OF BIORESOURCE COLLECTIONS
06.02.00 Veterinary and Husbandry
DescriptionThe production of eggs is one of the most important indicators of the productivity of poultry, including chickens The main purpose of breeding chickens in the collections of genetic resources - conservation of genetic diversity. The chickens from the collection of genetic resources it is also possible to receive products, for example, in the form of eggs. The account of the egg productivity of the chickens showed that the intensity of egg production varies among representatives of different directions of productivity. The most stable egg-laying was possessed by chickens of breeds New Hampshire, Black Australian, Dutch white. These breeds are bred as breeds of egg direction of productivity. But they are characterized by long downturns in egg production, lasting more than 7 days. Chickens of meat direction by stable, but low intensity of egg production. All the chickens had a short period For all chickens a short period is characteristic, when the egg-laying is kept at a certain level. It is 30-40 days, after which there is a gradual decrease in this indicator. Such a high level of genetic diversity in egg production in gene pool makes it possible to use this bird as a model object for studying its features
