The research focused on two production systems of fattening pigs : conventional system (housing on cross - barred floor) and ecological system (housing on deep litter). Favorable climatic conditions for pig meat production, possibilities to produce cheaper food of better quality and great amounts of litter, are a good basis for making ecological pig production widely accepted by family farms. Ecological aspect of such production of pigs, along with its economic analysis will be key factors, which will influence pig producers in their choice of the most suitable technological solution. In comparison to the conventional way of keeping pigs, main advantages of pig housing on deep litter are cheaper building and equipping of pens, better effect on health conditions of pigs, as well as easier manipulating with manure. Following this context, the research objective was to analyze economic indicators of different pig production systems and to compare economic results obtained in conventional and ecological way of pig production. The research aim was to determine economic possibilities and to evaluate results of production systems in question, justifying their economic and social aspects.
