The goal of this study was to compare the values of intestinal digestibility of undegraded crude protein in the rumen of ruminants, determined by a mobile bag technique in cannulated animals and by an enzymatic technique using pancreatin, for a wider range of feedstuffs. The largest subset of bulk feeds (n=39), which included green forage of alfalfa, clover, meadow grass, clover-grass, meadow foxtail and timothy, silage of corn, beet tops, alfalfa, clover, crushed beans, barley and pea with wheat, grass silage with higher dry matter content, and alfalfa hay and barley straw, had the lowest value of correlation coefficient (r=0.760, % RSD=7.69). The highest value of correlation coefficient was recorded for the subset of extracted meals (cottonseed, rapeseed soybean, linseed, groundnuts and sesame) with feedstuffs from animal sources (fish and meat-bone meals and blood meal)-r=0.941, % RSD=3.48, n=14. The third subset, consisting of grains (n=22), i.e. wheat, barley, rye, oats, corn, had the correlation coefficient r=0.852 and % RSD=5.05.
