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.

Tytuł	Potencjał energetyczny biomasy roślinnej i możliwości wykorzystania do celów energetycznych
Title	Energy Potential of Agricultural Crops Biomass and Their Use for Energy Purposes
Słowa kluczowe	biomasa, słoma, siano, rośliny energetyczne, potencjał energetyczny
Key words	biomass, straw, hay, perennial energy crops, energy potential
Abstrakt	Zapewnienie bezpieczeństwa energetycznego, uniezależnienie się od paliw kopalnych oraz ograniczenie emisji gazów cieplarnianych skłania do wykorzystywania odnawialnych źródeł energii. Celem badań jest ocena potencjału energetycznego biomasy roślinnej z produkcji rolnej i wskazanie możliwości jej wykorzystania do produkcji energii elektrycznej i ciepła. Do badań wykorzystano dane z Powszechnego Spisu Rolnego 2010. Na podstawie szczegółowej analizy zmian zachodzących w produkcji rolniczej w latach 2010-2015 dokonano aktualizacji danych. Przyjęto założenie, że zmiany w gminach zachodziły w taki sam sposób jak w województwach. Potencjał energetyczny biomasy roślinnej oszacowano uwzględniając: nadwyżki słomy, siana i plantacje roślin energetycznych. Z przeprowadzonych badań wynika, że Polska dysponuje energetycznym potencjałem biomasy roślinnej kształtującym się na poziomie 305,8 tys. TJ rocznie, który może być wykorzystany do celów energetycznych bez zagrożenia dla produkcji żywności.
Abstract	The need to ensure energy security, decouple energy production from fossil fuels and reduce greenhouse gas emission are driving the use of renewable energy sources. The purpose of the study is to assess the energy potential of agricultural crops biomass and to indicate its potential for electricity and heat production. The data from the Agricultural Census 2010 were used for analyses. On the basis of the detailed analysis of the changes in agricultural production in the years 2010-2015 the data has been updated. Is was assumed that the changes in communes were similar to those in voivodships. The energy potential of the crop biomass was estimated taking into account surpluses of straw, hay and perennial energy crops biomass. The study shows that energy potential of the biomass without jeopardizing food production amounts at 305,8 thousand TJ per year.

Tytuł	Koszty żywienia krów mlecznych a wyniki ekonomiczne gospodarstw
Title	Costs of feeding dairy cows and economic results of dairy farms
Słowa kluczowe
Key words
Abstrakt
Abstract	The paper presents results of studies on costs and profitability of milk production in various diets of dairy cows. For the three farms specialized in milk production, were developed two variants of feeding cows on the basis of hay silage produced on the farm. One scenario assumes maintenance of current milk yield of dairy cows and use of concentrates. The second eliminated concentrates from the feed and assumes a reduction of milk yield of cows. The analysis included the costs and profitability of milk production in farms.

Title	Costs of meadow-pasture fodder on the example of milk farms in Lodz Province
Słowa kluczowe	struktura kosztów bezpośrednich, koszty jednostkowe, ceny nasion traw, ceny nawozów mineralnych i innych środków produkcji
Key words	structure of direct costs, unit costs, prices of grasses, prices of artificial fertilizers and other production means
Abstrakt	W artykule zaprezentowano wyniki badań z terenu województwa łódzkiego prowadzonych w latach 2004-2006, dotyczące zróżnicowania kosztów bezpośrednich pasz łąkowych i pastwiskowych w gospodarstwach mlecznych.
Abstract	The aim of the paper was to analyze the costs of meadow pasture folder in milk farms. There were analyzed farms from Łodz Province. Taking into consideration process of liberalization on milk market and respecting the necessity of looking for possibility of unit cost decreasing, the pasture feeding could be more and more important. In that context this issue connected with botanic content of the turf and with fertilizing intensification and nurturing of pasture seems very important and could have an influence on increasing competitive advantages between milk producers. It could have also influence, in the long term perspectives, on increasing milk production concentration, first of all in the farms, which have large pasture area, especially near the centre of the farm. In the researched period 2004-2006the average direct costs 1 dt of pasture cutting grass fluctuated from 1,88 to 1,93 zl; meadow cutting grass . from 2,18 to 2,23 zl; meadow hay . from 14,17 to 14,53; hay-silage from 6,55 to 6,72 and silage from 3,57 to 3,66 zl. Moreover, in the individual researched years occurred between milk farms significance differences of costs those fodder. The biggest were in 2005 year. Taking the lowest costs as 100%, the highest level in case of pasture cutting grass was 155,3%; in case of meadow cutting grass was 140,0%; meadow hay was 163,4%; hay-silage was 134,8% and silage was 137,4%. The diversity of unit costs could be recognized as a significant, and what is more, it shows the possibilities of decreasing the fodder costs in the specialized farms.
