Title	Environmental Assessment of the Life Cycle of Bovine Compound Feeds from a Feed Milling Plant in a Large Commercial Farm in Wielkopolska Region, Poland
Słowa kluczowe	environment, life cycle analysis, impact category indicator, compound feed, feed mill, Poland
Key words	environment, life cycle analysis, impact category indicator, compound feed, feed mill, Poland
Abstrakt	In recent years, the importance of environmental threats associated with intensive livestock production has been emphasized. Compound feeds make up a part of the animal production chain. A complete assessment of the animal production system with regard to environmental criteria is therefore impossible without considering the environmental consequences of feed production. The goal of this research is to fill the gap in an environmental assessment of production processes of compound feeds in Poland. The study presents an assessment of production impacts of bovine compound feeds according to Life Cycle Analysis (LCA) methodology. The data for analysis were based on the set of information obtained from the feed milling plant located in a commercial agricultural enterprise in the Wielkopolska region in the years 2015-2016. An inventory table of inputs was prepared in relation to the functional unit of 1 ton of compound feeds and two phases of production processes, i.e. upstream and core. For average compound feed, the impact category indicators for the global warming potential, acidification, eutrophication, photochemical ozone formation, consumption of mineral resources, fossil fuel resources and the emission of the respirable particles were respectively: 605.9 kg CO2 eq, 8.73 kg SO2 eq, 3.32 kg PO4 eq, 0.73 kg ethylene eq, 3.4x10-3 kg antimony eq, 5141.1 MJ and 2.25 kg PM2.5 eq. The upstream phase had the greatest effect on investigated impacts, while the core processes phase had a relatively low impact on environmental threats. It is recommended to broaden the scope of the research for a larger group of feed milling plants with more complex manufacturing processes, with a more branched supply structure and a wide range of compound feeds for different animal types. The obtained data can be a valuable source base in prospective analyses of the life cycle of various animal products in Poland.

Tytuł	Carbon Footprint of Beef Cattle in a Conventional Production System: a Case Study of a Large-Area Farming Enterprise in the Wielkopolska Region
Title	Carbon Footprint of Beef Cattle in a Conventional Production System: a Case Study of a Large-Area Farming Enterprise in the Wielkopolska Region
Słowa kluczowe	carbon footprint, beef production, emission of greenhouse gases, life cycle assessment, agriculture
Key words	carbon footprint, beef production, emission of greenhouse gases, life cycle assessment, agriculture
Abstrakt	Animal production is a significant source of greenhouse gas (GHG) emissions. One of the major challenges in sustainable management is to mitigate the effects of climate change by reducing GHG emissions. The diversity of animal production systems and accompanying diversification of technological processes, mean that specific production effects can be obtained at different levels of GHG emissions. The aim of the study was to determine the carbon footprint (CF) of beef cattle grown in a conventional system (i.e. indoor confinement). The research was carried out on the beef cattle farm belonging to a large-area enterprise, Długie Stare Ltd. The beef cattle production system consisted of the following subsystems: a basic breeding herd (consisting of suckler cows, replacement heifers and calves up to 6.5 months), breeding heifers, breeding bulls and fattening bulls. The method of life cycle analysis (LCA) in the stages from "cradle-to-farmgate" was used to assess the GHG emissions associated with the production of beef cattle. The average CF in the entire beef cattle production system was 25.43 kg of CO2 kg-1 of live weight of marketed cattle, while in the individual subsystems of basic breeding herd, breeding heifers, breeding bulls and fattening bulls, the CF (after GHG allocation) was: 11.0 kg CO2 eq., 34.30 kg CO2 eq., 27.32 and 25.40 kg CO2 eq., respectively. GHG emissions associated with young calves staying in the cow-calf pairs until weaning (in the period from 0-6.5 months), had a decisive influence on the final CF in each of the subsystems of beef cattle production. The second important factor directly affecting the CF was GHG emissions related to methane (CH4) enteric fermentation and manure management. Knowledge of factors affecting the CF structure allows better identification of critical areas in production processes with high GHG emission potential. Information on the CF of beef cattle and beef meat responds to a wider societal demand for the ecological characteristics of market products, which ultimately contributes to improving their market competitiveness.

Title	Assessing the Greenhouse Gas Emissions by Carbon Footprint in Intensive Agricultural Production Based on the Examples of Winter Oilseed Rape
Słowa kluczowe	ślad węglowy, gazy cieplarniane, produkcja roślinna, nawożenie azotowe, praktyki rolnicze, rzepak ozimy

Abstrakt	Aktualnie ważnym wyzwaniem dla sektora rolniczego jest redukcja emisji gazów cieplarnianych (GHG) w celu złagodzenia skutków zmian klimatycznych. Istnieje potrzeba dokładnej identyfikacji źródeł emisji oraz upowszechnienia praktyk rolniczych, które przyczyniałyby się do zmniejszenia emisji we wszystkich ogniwach produkcji roślinnej. Do przeprowadzenia obiektywnych porównań i wyboru najlepszych rozwiązań technologicznych według kryterium emisyjności potrzebna jest szczegółowa ocena ilościowa emisji GHG. W opracowaniu przedstawiono ocenę emisji GHG w produkcji roślinnej za pomocą śladu węglowego (CF). Udział operacji technologicznych w powstawaniu CF scharakteryzowano na przykładzie rzepaku ozimego. Wyniki badań wskazują, że największe znaczenie w kształtowaniu CF ma proces nawożenia mineralnego. Wpływ pozostałych procesów na CF jest wielokrotnie mniejszy. Miejscem głównych emisji GHG w nawożeniu mineralnym rzepaku są emisje bezpośrednie i pośrednie GHG z pól. Po emisjach GHG z pól, produkcja nawozów stanowi drugie źródło emisji z nawożenia. Zmiany praktyk rolniczych polegających na zwiększeniu efektywności nawożenia azotowego oraz stosowaniu nawozów o niskich współczynnikach emisji stwarzają obecnie możliwość redukcji emisji GHG i przez to, tym samym mogą przyczynić się do zmniejszenia CF produktów roślinnych.
Abstract	Currently, a major challenge for the agriculture sector is the reduction of greenhouse gas (GHG) emissions in order to mitigate the effects of climate change. There is a need to accurately identify the sources of emissions and to promote agricultural practices that would contribute to the reduction of emissions in all chains of crop production. To carry out objective comparisons and choose the best technological solutions according to an emissivity criterion there is a need for the detail quantitative assessment of GHG emissions. The study shows an assessment of GHG emissions in crop production using the carbon footprint (CF). The share of technological operations in CF formation was characterized based on the example of winter oilseed rape. The results indicate that the process of fertilization is of the greatest importance in the CF development. The impact of other remaining processes on the CF is several times smaller. The main hot-spots in GHG emissions due to mineral fertilization are associated with direct and indirect GHG emissions from the fields. Emissions from the production of fertilizers are the second source of emissions from the fertilization process, following GHG emissions from the fields. Changes in agricultural practices by increasing the efficiency of nitrogen fertilization and the use of fertilizers with low emission factors make it possible to reduce GHG emissions at present, and thereby contribute to the CF reduction of crop products.

Tytuł	Emisje gazów cieplarnianych związane z różnymi scenariuszami diet mieszkańców Polski
Title	Greenhouse Gas Emissions Associated with Different Diet Scenarios of Poland’s Inhabitants
Słowa kluczowe	skład diety, spożycie mięsa, wartość kaloryczna żywności, emisja gazów cieplarnianych, efekt środowiskowy
Key words	diet composition, meat consumption, food caloric value, greenhouse gas emission, environmental effect
Abstrakt	Ważnym działaniem w strategii ograniczania emisji gazów cieplarnianych (GHG) na poziomie krajowym może być promowanie zmian nawyków żywieniowych przez zmianę profilu gatunkowego mięs i ilości mięsa w racjach pokarmowych ludności. Celem badań była ocena możliwości redukcji emisji GHG za pomocą różnych scenariuszy diet w Polsce. Wyróżniono następujące typy diet: przeciętną, wegańską, wegetariańską lakto-owo, mięsożercy, mięsną drobiową, demitarian i o obniżonej wartości kalorycznej. Analizując skład diet oraz emisję GHG przy produkcji żywności w przeliczeniu na 1 kcal różnych produktów obliczono wielkość emisji tych gazów w skali kraju dla różnych scenariuszy diet. Wyniki badań wskazują, że modyfikacja preferencji żywieniowych w kierunku diet: wegańskiej, mięsnej drobiowej oraz demitarian pozwala osiągnąć wyraźne zmniejszenie poziomu emisji GHG w stosunku do przeciętnej diety.
Abstract	An important action in the strategy for reducing greenhouse gas (GHG) emissions at the national level can be the promotion of changes in eating habits, by changing the profile of meat species and quantities of meat in the food rations of the population. The aim of this study was to assess the possibility of reducing GHG emissions by different diet scenarios in Poland. The following types of diets were distinguished: average, vegan, vegetarian lacto-ovo, carnivore, poultry meat, demitarian, and reduced energy value. By analyzing the composition of the diets and GHG emission related to the food production per 1 kcal of different products, emissions of these gases on a national scale for different diet scenarios were calculated. The study results indicate that the modification of food preferences towards diets – vegan, poultry meat and demitarian – allows GHG emissions to be markedly reduced compared to the average diet.
