In this paper two technical-technological systems of pig nutrition processes are analysed, using silage grain corn: first, system of fluid nutrition with feed distribution with pipeline and valves for dosage, and second, distribution of feed more density (pulpy feed) with mobile tractor dispenser. Work quality of systems determined through distribution uniformity of dry matter (DM) in feed in function of lenght feed-line. In this case, the mobile dispenser was much better. In nutrition cycle small degree of feed uncomposing is established (fig. 5 and 6). The results of researches showed technological satisfactory in work quality by stationary feed system (distribution with hydraulic transport of fluid feed using pipeline) at 100 m lenght. Investments in mobile nutrition system are importantly lower, and also the system is easy to manipulate. This analyse showes that economical aspect of installation of higher degree mechanization for pig nutrition with liquid and pulpy feed by smaller farms capacity (to 2500 fattening swine/yearly) are very controversial, and it is dependent on individual cases and production of swine meat.
