The quality of 4 oat varieties were compared from the viewpoint of their suitability for nutrition of monogastric animals. Subject to testing were 3 varieties of unhulled oat Neon (UK), Adam (DK) and SG-K 7555 (CZ), and one hulled variety of oat Doris (SWE). The differences in average content of nutrients in varieties of unhulled oat were not significant. We found marked differences (P0.001) in comparison with the variety Doris, the content of fibre in which was 5 times higher and it made itself felt in lower content of metabolizable energy. Spectrum of individual amino acids, especially lysine, arginine and threonine is more favorable in oat varieties than in other cereals, the proportion of lysine out of total content of amino acids being the highest in the variety Doris. The results of feeding experiments, performed with male specific pathogenfree (SPF) Wistar rats show that the efficiency of unhulled oat varieties used as source of proteins in nutrition of animals is better. Higher content of crude protein and fat, lower content of fibre, higher energetic value and value of PER are characteristic of the varieties of unhulled oat
