Abstract: 
The present study was performed to investigate the effect of feeding practical rations based on various type of cereals and grass supplements on body weight gain, carcasss quality and fatty acid composition of adipose tissue in growing geese. Therefore, an experiment with growing geese was performed consisting of two feeding periods. Three groups of geese were fed rations based predominately on (I) maize, (II) barley, (III) wheat and oats. Those rations which were supplemented with soy bean meal, rapeseed meal and green meal were isonitrogenic (15.2% crude protein in average of the two feeding periods) but had different energy values (ration I, 10.25; ration II, 9.60; ration III, 9.59 MJ ME/kg, average of the two feeding periods). A fourth group was fed rations consisting of barley, wheat and grass (period I) or barley and grass (period 2). All rations had low concentrations of crude fat. In groups I to III body weight gains of the geese followed the energetic values of the rations. It was highest in group I, and similar in groups II and III. Geese fed the ration IV had markedly lower weight gains and additionally lower carcass weights, lower breast muscle percentages and higher breast muscle skin percentages than the geese fed rations I, II and III. Other parameters of carcass quality were not influenced by the ration. The fatty acid composition of adipose tissue was characterized by high percentages of saturated and monounsaturated fatty acids, and relatively low percentages of polyunsaturated fatty acids, regardless of the ration. Between the four groups, there were only slight differences, and there existed no correlation between the fatty acid composition of the ration and that of adipose tissue. The reason for this is that fatty acids incorporated into tissue lipids because of the low fat concentrations of the rations derive mainly from de-novo synthesis from carbohydrates.
