The Directive on National Emission Ceilings specifies the reduction of ammonia (NH3) emissions among other air pollutants, which is most significant for the agricultural sector. The ammonia emission limit set for Hungary was a 10% reduction by 2020, while the target of 32% should be reached by 2030 compared to the 2005 reference year. The paper presents the results of a survey on pig production technology in Hungary from 97 domestic farms. The study aims to know the level of implementation of reduction techniques in livestock production and manure management and highlights the need for further improvements in this production sector. The research found that the application of ammonia reduction techniques was not considered widespread, either in livestock buildings or in manure storage (treatment) and during field application. For almost all (more than 90%) pig production groups, the housing systems were the reference without additional emission reduction. For manure storage, farms have insulated storage under the current regulation, however, significantly more emission reduction technologies were in the variant without cover or crust. Slurry spreading was mainly used with manure application techniques, but more emission-friendly injection and band spreading were also emerging. Besides the expected immediate incorporation, a high proportion of manure was applied between 12 and 24 hours or even after 24 hours. In the studied elements of manure management, significant improvements are needed in applying techniques to reduce ammonia emissions. Effective results can be achieved even by shortening the time between manure application and incorporation with efficient work organization.

W artykule poruszono kwestie związane z funkcjonowaniem zaplecza surowcowego dla polskiego przetwórstwa mięsa wieprzowego. Analizowano możliwości zaspokojenia popytu na żywiec wieprzowy z produkcji krajowej oraz z importu. Celem opracowania jest ocena zaszłości oraz aktualnego stanu sektora produkcji żywca wieprzowego w kraju w latach 2005-2019 oraz jego powiązań z przetwórstwem mięsa wieprzowego. Stwierdzono, że mimo licznych zawirowań otoczenia gospodarczego zachodzą w nim procesy konsolidacji wpływające na stabilizację podaży wieprzowiny, przy względnie stabilnej wielkości importu mięsa wieprzowego narynek krajowy.

The article raises issues related to the functioning of the raw material base for Polish pork processing. The possibilities of satisfying the demand for live pigs from domestic production and from imports were analyzed. The aim of the study is to assess the past and current state of the live pig production sector in Poland in 2005-2019 and its links with the pork processing. It was found that despite numerous turbulence in the economic environment, consolidation processes taking place affecting the stabilization of the supply of pork, with a relatively stable volume of pork import into the domestic market.
