Abstract
The aim of the experiment was to determine, how the different ratios of the digestibility lysine/ metabolized energy (0.82, 0.87, 0.91 g DLYS/MJ AMEn) of the feed influence the performance of geese. There were 150 goslings (3 treatments, 5 cages/treatments, 10 birds/cages). The experiment has started and finished at the age of 3 and 9 weeks, respectively.The results of the experiment showed, the different ratios of DLYS/AMEn (0.82, 0.87, 0.91 g DLYS/MJ AMEn) did not influence the performance of young geese. Better growth performances were found for the 0.91 g DLYS/AMEn feed (feed intake, body weight gain, feed and energy conversion rate). This treatment coincided with high feeding costs. Based on these results we need more models and farm experiments to prove this tendency.

Summary
The results of the experiment showed, the different ratios of DLYS/AMEn (0.82, 0.87, 0.91 g DLYS/MJ AMEn) did not influence the performance of young geese. Több kísérlet eredménye arra utal, hogy az aminosavak emészthetőségét befolyásolja az etetett takarmány táplálóanyagai közötti kölcsönhatás is (Wallis et al 1985). A jelen dolgozat célja ezért annak megállapítása, hogy a takarmány különböző emészthető lizin- metabolizálható energia (AMEn) aránya miképpen befolyásolja a pecsenye ludak teljesítményét. A kezelések energia és fehérje és lizintartalma, továbbá a takarmány em. A megközelítőleg azonos metabolizálható energiakoncentráció mellett különböző mennyiségű lizin került a takarmányba bekeverésre, így a lizin-metabolizálható energia aránya kezelésenként eltérő.
