Abstrakt | Improving production efficiency, increasing gross and marketable output is inextricablylinked to comprehensive intensification, that is, with the growth of additional investmentsin the development of agricultural production. The increase in capital investments isthe basis for strengthening and improving the material and technical base, and for implementingscientific and technological progress. Increasing the intensity of agriculture and animalhusbandry contributes to more efficient use of land and livestock, increasing crop yields andlivestock productivity. The main link between crop production and animal husbandry is feedproduction. Creating a solid feed base is the most important condition for the development ofanimal husbandry. Its state and level of development determine the possibility of increasingthe number of animals, increasing their productivity, improving the quality of products andreducing the cost of the latter. It is proved that the level of productivity of animals by 50-80%is determined by their feeding. Due to the importance of feed, it is necessary that their productionis ahead of the pace of needs (growth of livestock and its productivity). When forminga feed base, it is important to take into account not only the total volume of feed that willensure the production of a certain amount of products, but also their balance with nutrients.As a rule, feed, namely green feed, silage, haylage, is not a commodity product, that is, thereare no permanent markets for them. These types of feed are grown by those farms that areengaged in animal husbandry and must create their own raw material base for obtaining themain feed. |

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. |

Wicki L. Changes in land use for production of energy crops in Poland

Tytuł | Changes in land use for production of energy crops in Poland |
Title | Zmiany powierzchni produkcji roślin energetycznych w Polsce |
Słowa kluczowe | bioenergia, bioetanol, biodiesel, biogaz, konkurencja żywność – energia |
Key words | bioenergy, bioethanol, biodiesel, biogas, food–energy competition |
Abstrakt | Celem opracowania jest ocena, czy w Polsce produkcja nowoczesnych biopaliw wytwarzanych z surowców rolniczych konkuruje z produkcją żywności. W pracy wykorzystano dane gromadzone przez Główny Urząd Statystyczny i Agencję Rynku Rolnego (ARR). Wykorzystano dane dotyczące powierzchni gruntów ornych w Polsce, plonów wybranych roślin, pogłowia zwierząt oraz dane o ilości i strukturze produkcji energii oraz o wielkości produkcji biogazu rolniczego, bioetanolu i biodiesla. Dane dotyczące ilości surowców zużywanych w produkcji biogazu rolniczego pozyskano z ARR. Analizą objęto lata 2005-2016. Produkcja bioenergii w oparciu o surowce pochodzenia rolniczego silnie wzrastała w analizowanym okresie, z 5 TJ w 2005 roku to 42 TJ w 2016 roku. Około 92% energii wytwarzanej z surowców rolniczych stanowi bioetanol i biodiesel, które są produkowane z surowców pierwszej generacji. Produkcja ta konkuruje więc z produkcją żywności. Biogaz stanowi tylko 8% energii produkowanej z surowców rolniczych. W produkcji biogazu surowce drugiej generacji, czyli odpady stanowiły aż 75% wsadu. Udział powierzchni gruntów ornych przeznaczanych do produkcji surowców do wytwarzania biopaliw wynosił 5,6% w 2016 roku. W 2005 roku było to 1,5%. Oznacza to, że w Polsce produkcja bioenergii z surowców rolniczych konkuruje z produkcją żywności i pasz, a dalszy jej wzrost nie jest pożądany. Niemniej, przy spadku rozmiarów produkcji zwierzęcej jest to szansa na zagospodarowanie nadwyżek ziemi i produkcji. W przyszłości powinny być podejmowane działania mające na celu zwiększenie wykorzystania surowców drugiej generacji w produkcji bioenergii, a zużycie surowców pierwszej generacji powinno być, w miarę możliwości, ograniczane. |
Abstract | The goal of the article is to evaluate whether production of modern biofuels in Poland competes with food production. CSO and AMA data have been used in the analysis. The data in question refers to the area of arable land in Poland, yields and livestock as well as renewable energy production structure and quantity and production of biodiesel, bioethanol and agricultural biogas. Data concerning quantity of raw materials used for production of the agricultural biogas have been accessed from AMA . Data for 2005-2016 have been collected. Production of bioenergy based on agricultural raw materials has significantly increased. From 2005 to 2016, it increased from 5 to 42 TJ . Approximately 92% of bioenergy from agricultural sources are bioethanol and biodiesel produced from the first generation of raw materials, the production of which is in direct competition with food production. The share of biogas was 8% only. Waste constituted 75% in the raw materials used to produce biogas. The area of production of energy crops has reached 5.6% of arable land in 2016 from 1.5% in 2005. It means that in Poland production of bioenergy from agricultural sources competes with food and feed production and its further increase is not desirable. Actions focused on the increased use of the second generation raw materials for energy production and decreased use of food raw materials should be taken. |

Tytuł | Koszty produkcji paszy z mieszanki pastwiskowej w różnych warunkach siedliskowych |
Title | Production costs of feed from a grazing mixture grown under different environment conditions |
Słowa kluczowe | mieszanka pastwiskowa, plony, jakość paszy, koszty produkcji |
Key words | grazing mixture, yields, forage quality, production costs |
Abstrakt | Przedstawiono wielkość i wartość pokarmową plonów oraz ocenę kosztów produkcji paszy pastwiskowej w różnych warunkach siedliskowych (pole uprawne, użytek przemienny, łąka) w zależności od ilości wysiewu nasion mieszanki (10, 20 i 30 mln szt. nasion/ha) i udziału w niej koniczyny białej (20 i 40% nasion). Mieszankę wypasano krowami mlecznymi 4-5 krotnie w okresie wegetacji. Mieszanka pastwiskowa uprawiana na polu w stanowisku po ziemniaku na oborniku cechowała się najwyższym plonem i zarazem najniższymi jednostkowymi kosztami produkcji paszy. Zwiększenie ilości wysiewu nasion mieszanki nie wpływało znacząco na wielkość plonu, a powodowało wzrost kosztów produkcji paszy. Zwiększenie udziału koniczyny białej w mieszance nasion wpływało korzystnie na wielkość i jakość plonu oraz obniżkę jednostkowych kosztów produkcji paszy. |
Abstract | Yields and feeding value of the crop of a grazing mixture grown over a range of environment conditions (grass ley, alternate arable field/grass ley, meadow) were studied as affected by the seeding rate of the mixture (10, 20, 30 million seeds/ha) and by the percentage of white clover seeds in the mixture (20 and 40%). The mixture was grazed by dairy cows four-five times during the growing period. When grown after potatoes fertilized with farmyard manure the mixture gave the highest yields and the production of the feed incurred the lowest costs. While not increasing the yields in a significant manner higher seeding rates caused production costs to rise. Increased percentages of white clover in the mixture had a beneficial effect on the yields and crop quality while at the same time reduced unit costs of feed production. |
