The crude protein content and @entity535 profile of seven feedstuffs (linseed meal, @entity2829 gluten meal, rapeseed meal, rapeseed meal protected, @entity1460 meal, fullfat @entity1460 extruded and sunflower meal) were determined before and after ruminal incubation for 16 h in three bulls with large rumen cannulas. The intestinal disappearance of @entity1522 was measured using mobile bag technique. Ruminal incubation affected @entity535 profile of all experimental feedstuffs. Crude protein degradation varied from 29.3% for @entity2829 gluten meal to 86.4% for rapeseed meal. A tendency towards increased disappearance was observed for @entity367 , @entity3793 , @entity376 and @entity1521 and decreased disappearance for branched-chain @entity1522 . The intestinal crude protein digestibility was higher than > 80%, except rapeseed meal (66.4%) and sunflower meal (77.8%). The least digestible individual @entity1522 were @entity1853 and @entity6778 in rapeseed meal, @entity3793 and @entity1853 in rapeseed meal protected and @entity369 in sunflower meal. In general, the lowest @entity535 digestibilities were found in feedstuffs with the highest fibre content. The feedstuffs show that they have different potential for supplying of limiting @entity1522 . Of particular value are the feedstuffs with low crude protein degradability in the rumen and high intestinal digestibility of @entity1522 .
