Purpose of research - developing new and improving existing methods of maintenance, feeding and use of bulls, boars, sows and young pigs in specialized farms and efficacy of their use in the production of pork. Methods of research: zootechnical, technological, economic, statistical. Results of research. Grounded, optimized and applied in industry effective system of feeding, maintenance and use of hogs-producers, in the conditions of industrial technology which provides the increase of biological value of the mixed fodders, positively influences on the quantitative and high-quality indexes of sperm, reproductive function of producers, allows to decrease the production inputs of feed unit of products and promotes efficiency of their use. It is set that the use of bioactive feed addition of fitomin in optimum doses (90 g/days) in the ration of sucking sows positively influences on intensity of growth and safety of pigs. Efficiency of application of the mixed sperm at the industrial crossing, and also artificial changes in the quantity of nest of uteruses, mode of sucking of pigs substantially influence on living weight and milkness of uteruses, growth of pigs and consumption by them the mixed fodders. With the increase of amount of pigs in a nest from 10 to 30 living mass of uteruses in the moment of weaning of pigs diminishes on 3-11 % at simultaneous growth of their milkness on 26-47%. The maintenance of pigs on the deep bedding positively influences on their growth and development, meat and slaughter rates. Growing of sapling of pigs at the size of technological group less than 50 heads are effective, as provides the receipt of large average daily gain increases, for slaughter output, and increase maintenances of albumen in the middle test of meat and in the longissimus dorsi. Increase of living weight of pigs at the weaning to 20-22 kg are provided by an increase slaughter output, however results in diminishing of specific gravity of meat and increasing of specific gravity of fat in carcass. Range of application - agriculture.
