Title	Analysis of Business Cycles in the Breeding of Pigs, Cattle and Poultry and their Relationship to the Causality of Wheat and Rye Cultivation in Poland
Słowa kluczowe	pork cycle, hog cycle, agribusiness, breeding, cycles
Key words	pork cycle, hog cycle, agribusiness, breeding, cycles
Abstrakt	The article presents a study on the phenomenon of pig gaps in the perspective of pig, cattle, and poultry farming in Poland. The work attempts to define the phenomenon itself as well as to show the reasons for its occurrence and significance for the Polish economy. The study used a cross-spectral analysis, which indicated cyclical relationships and shifts between the studied time series. The methodology of the work was based on a simplified spectral analysis, i.e. the use of the square of coherence, spectral density and phase spectrum. In addition, the article uses a comparative method for selected production volumes. The results were analyzed in the context of occurrence of pig cycles for breeding and cultivation. The study showed the occurrence of the relationship between pig breeding and wheat and rye cultivation.

Tytuł	Opłacalność produkcji żywca wieprzowego w Polsce po integracji z UE
Title	Profitability of pig breeding in Poland after integration with the EU
Słowa kluczowe	ceny skupu, działania interwencyjne na rynku, koszty produkcji, opłacalność produkcji, rynek wieprzowiny
Key words	profitability of production, pork market, production costs, purchase prices, market interventions
Abstrakt	Celem badań było określenie zmian w opłacalności produkcji żywca wieprzowego w Polsce po integracji z UE. W analizie wykorzystano dane GUS, IERiGŻ oraz informacje z gospodarstw w Wielkopolsce, które produkowały 100 i więcej tuczników rocznie oraz prowadziły rachunkowość w ramach polskiego FADN. Z badań wynika, że na opłacalność produkcji żywca wieprzowego wpływają głownie ceny skupu trzody chlewnej oraz koszty pasz. Przystąpienie Polski do UE nie zlikwidowało zmian koniunkturalnych na rynku wieprzowiny. W okresie dekoniunktury większość producentów żywca wieprzowego nie podejmuje żadnych działań, ale część rolników przedłuża okres tuczu albo zmniejsza stada loch. W celu stabilizacji cen na rynku trzody chlewnej dąży się do wprowadzenia rozwiązań systemowych i poszukuje się nowych rynków zbytu.
Abstract	The aim of the research was to estimate the changes in profitability of production of pigs for slaughter. The analysis included data from GUS (Central Statistical Office) and IERiGŻ (Institute of Agricultural Economics and Food Economy), as well as information from farms in Wielkopolska province that produced hundred or more porkers yearly and conducted accountancy within the Polish FADN system in the 2004. The profitability of production of pigs for slaughter is influenced primarily by the purchase prices of pigs and fodder costs. Polish accession to the EU has not stopped changes in the conditions in the market of pork meat. During periods of adverse conditions most breeders do not undertake any actions, but some farmers prolong the feeding period or decrease the size of sow herds. In order to stabilize prices in the pig market the introduction of system solutions and new outlet markets are being sought
