The average composition of amino acid profile of feed’s protein (0) was compared with the amino acid rumen undegraded protein (RUP), by calculating the distances of x² between each file of two proteins. The greater value of x², the greater difference between compared proteins. The biggest distance in cereals between 0 fraction and RUP was noted for rye (x² = 73.97), lower for barley (x² = 31.22) and the lowest for wheat (x² = 20.6). The composition of wheat AARUP is the closest to the AA content in feed. The differences in 0 protein fraction and RUP were of a little importance for soybean meal and for field bean (x² = 15.3 and x² = 23.4, respectively). Bigger distance level between protein fractions was noted for peas (x² = 81.2). Amino acid profiles of 0 fraction and amino acid profiles of RUP in hay of the Italian rye-grass and of the red clover were similar (x² = 46.5 and x² = 59.6, respectively), but they were considerably different from analogous protein fractions of meadow fescue and perennial rye-grass (x² = 144.5 and x² = 167.86, respectively).

Średnie sklady aminikwasowe białka pasz (0) porównywano z aminikwasami białka nierozłożonego w żwaczu (RUP) stosując obliczenia odległości x² pomiędzy każdym zbiorem dwóch białek. Im wyższe wartości x², tym większa różnica pomiędzy porównywalnymi białkami. Największą odległość pomiędzy frakcją 0 zbóż a RUP zanotowano dla żyta - x² = 73,97, następnie dla jęczmienia - x² = 31,22 i najmniejszą dla pszenicy - x² = 20,6. Skład AARUP pszenicy jest najbardziej zbliżony do zawartości AA w materiale oryginalnym. Różnice we frakcjach białka 0 i RUP były niewielkie dla śruty sojowej i bobiku (x² = 15,3 i 23.4). Większą odległość pomiędzy frakcjami białek zanotowano dla grochu - x² = 81,2. Profile AA frakcji 0 i RUP w sianie z życicy wielokwiatowej i koniczyny czerwonej były podobne ( x² = 43,9 i 59,6), ale różniły się znacznie od analogicznych frakcji białek siana z kostrzewy łąkowej i życicy trwałej (x² = 144,5 oraz 216,5).
