AB The aim of a growth model experiment in laboratory rats was to check the nutritive value of the set of newly bred spring barley lines with different grain characteristics. The followed set contained feed type hulless lines bred in the Agricultural Research Institute Kroměříž , Ltd. KM1771 (1), KM 1057 (2), food type hulless lines KM 2082 (3), KM 2092 (4), KM 2062 (5) and lines formed on the basis of crossing with food donors of a waxy endosperm type - hulless line Wabet x Washonubet (6), hulled line Wabet x Krona (7) and Wabet x Kompakt (8). The line Kompakt x Krona (9) and the malting variety Nordus were used as a control (10).The best results of an average daily gain and feed conversion ratio (FCR) (9.19 g; 2.29) were achieved by feeding the line KM 1057 (2), conversely, the worst by feeding food barley of the waxy type (average daily gain in animals of experimental group 6 was only 8.01 g and FCR 2.54). This material also had the highest β-glucan content (7.1 %) out of the followed set. The lowest β-glucan content was detected in the sample 9 (3.88 %). Linear dependence between intake of β-glucans (x) and cholesterol content in rat's blood (y) was: y = -0.0591x + 3.8102, R<sup>2</sup> = 0.4681. The found dependence was statistically highly significant (P
