In an experiment carried out with 102 Landesian geese the result was that the breeding of cramming goose basic stock can be solved without animal and imported plant proteins. A good result can be reached, besides ad libitum feeding of green alfalfa, with such a concentrate of 16 per cent raw protein content which contains 0.94 g lysin, 0.85 g methionin and cystin calculated to 1 MJ metabolizable energy. The feeding of green alfalfa with 5.6 E/g saponin content had no antinutritive effect on the geese. During the ten-week fattening period the young geese consumed an average of 200 g green alfalfa. The maximum consumption was 360-400 g. The mass and size of the gizzard of animals consuming ad libitum green alfalfa was greater than that of those which consumed only concentrates. The size and mass of other parts of the digestive tract did not change. The volatile fatty acid concentration found in the caecum verifies that the intensity of microbic raw fibre digestion does not rise in the caecum as an effect of greater raw fibre consumption. The chemical composition of the muscles did not change and the quality of the liver was good.
