The aim of the study was to show changes in the volume of production, foreign trade and the prices of geese in Poland against the backdrop of world production, along with the presentation of new trends. The most important producer of geese in the world was China, whose production reached 95% of world production in recent years. Poland remains second in the ranking (with the production of approx. 30,996 tons, which accounted for 1.2% of world production in 2016), and is followed by countries such as Egypt (1.06%) and Hungary (1.02%). Prices of goose meat were the highest of all poultry species and, compared to chickens, they were higher, ranging from 60% in 2005 to 170% in 2017. In Poland, production was export-oriented. Starting from 2012, interest in goose meat on the domestic market has increased, and consumption reached a level of 40% in the period between 2012-2013. Production in the coming years will probably increase due to the advantages of goose meat, as well as due to the acquisition of extremely valued down and feathers.

, whereas in 2011 production carried out at this stocking density would result in losses. To maintain the current income level of farmers, it would require an increase of 5-6% in meat prices. key words: broiler, stocking density, broiler production income Development of animal production technology allowed production of animals on growing production scale in modern, fully equipped houses. Due to the climatic conditions of Poland, broiler chickens are kept in poultry houses, which should provide animals with optimal welfare and living conditions. Currently, the systems used to *This work was financed from DS 3 105/KZiMA.

1. The effects of changes in technical efficiency on the increase of broiler production are presented for the period 1994-2013 based on the panel data from seven farms located in southern and central Poland. A total of 766 cycles were analysed. 2. The Cobb-Douglas production function was used to assess the changes of output elasticities as well as technical changes in broiler production, for 5-year sub-periods separately. 3. Technical indices of broiler production significantly improved between years 1994-2013: feed conversion ratio decreased from 2.50 kg/kg to 1.78 kg/kg, mortality rate from 8.8% to 4.0% and daily weight gain increased from 37.1 g/d to 58.7 g/d, respectively. 4. Before accession to the EU, there was a substantial increase of fixed capital connected with modernisation of buildings and equipment. In the period 1994-2013, inputs of fixed capital per kilogram of livestock increased by 72% and at the same time the input of labour decreased by 56%. 5. Technical changes in years 1994-1998 contributed to a rapid production increase at a rate of 4.6% annually and only by up to 0.7% annually during 2009-2013. The slowdown of production rate increase after 2009 was partially caused by decreasing the stocking density.

Celem pracy jest analiza wpływu wybranych czynników na poziom cen żywca brojlerów w okresie przed przystąpieniem Polski do UE (1995-2004) oraz po akcesji (2005-2015). Wykazano, że w pierwszym okresie na cenę żywca decydujący wpływ miały czynniki kosztowe (cena piskląt, paszy i pszenicy). W drugim okresie nastąpił wzrost wpływu czynników popytowych, w tym sezonowy wzrost cen związany ze zwiększonym popytem na mięso drobiowe w miesiącach letnich.
