In the article, the technique of an estimation of reproductional qualities of boar- producers with developed by laboratory of development of theoretical bases of selection of animals of Don State Agrarian University selection indexes, is stated in detail. The approbation of the module of an index estimation of the program complex under production conditions of Shelonskiy state farm in Pskov area is carried out

The article reflects the results of the scientific research on creation and implementation of applications in industrial conditions of livestock enterprises of the country. The staff of the laboratory of the development of theoretical bases of selection of animals of Don SAU has created the selective cross-breeding information filter “SIF”. The system is constantly updated with new programs. The analysis of the information accumulated in the system allows to develop the recommendations, to make operational decisions and correct selection of the program

The algorithms of estimating breeding value, allowing increasing its accuracy several times are developed on the basis of establishment of the selection characteristics of existing selection criteria and the definition of the coefficient

The article contains the experience of the development of the methodology and the computer program for calculation of regional and local systems of pigs hybridization at the example of the Rostov region (Russia). Crossing the GP lines for F1 should be organized in multiplier farm, which may be separate farms and to be part of large commercial farms. For the production of F1 in a multiplier farm, we must breed a purebred specialized paternal and a maternal line, selected on the effect of combining ability. For the successful functioning of the system of hybridization, it is necessary to build a genetic pyramid, including breeding and genetic centers (nucleus farm), multiplier farm, reproducing the baseline. The article gives a detailed calculation of sow population of levels of P, GP, GGP for maternal and paternal breeds of pigs. The program uses user-defined parameters of pigs productivity, of the simulated population, and the parameters characterizing the intensity of selection of young animals. To ensure annual production of 1,822 million pigs in the Rostov region it is necessary to provide the availability of brood stock in the amount of 89 thousand heads, 6 800 heads in the structure of grandparent flocks (GP), 730 heads in the structure of the Grand-Grand-parent stock (GGP), excluding sows second maternal and paternal breeds

Nowadays, domestic pig production is dynamically changing in technological and selection terms and is one of the most effective sectors. In the current conditions of pig breeding in intensive technology, the requirements to the level and direction of pig production, the rational use of genetic resources are increasing. The development of effective methods for the production of pork on the basis of the wide use of highly productive breeds and types of both imported and domestic selection allows to obtain the maximum possible productivity of animals, to produce pork of good quality, to reduce the cost of production and to fully realize the genetic potential of animals. Genetic and selection techniques have significantly changed the physiological, morphological and productive capabilities of modern animals. In connection with this, the actual for the pig industry is the identification of opportunities to increase the duration of the use of pigs, and the inclusion of new indicators in breeding work when creating specialized maternal lines. The research was carried out on the electronic database (KP ACC, OOO "Selikom", Ryazan), the breeding center "Lozovoye" ZAO "Plemzavod-Yubileyniy" of the Tyumen region. The center is engaged in thoroughbred breeding and improvement of four pigs: large white, landrace, pietren, duroc
