Extract

Spring barley is the most widely produced cereal in Northern Ireland. Riviera and Dandy are the main varieties but there is a lack of information regarding their nutritive value. Variety and location of production affect the nutritive value of barley (Valaja et al 1997). An aim of this study was to determine the nutritive value of Riviera and Dandy and also to examine the effect of location of production. Cereal grains contain a high level of non starch polysaccharides (NSP). The major NSP present in barley are β-glucan and arabinoxylan and supplementation with exogenous enzymes has been shown to increase digestibility to different extents (Yin et al 2000). A further aim of this study was to examine the effects of a mixture of β-glucanase and xylanase on these two varieties.
