A high content of non-starch polysaccharides (NSP), namely arabinoxylans (AX), in rye is a reason for the potential adverse effect of this grain on intestinal functions, gut microflora, absorption of nutrients and performance indices. As such, the use of rye grain in intensively produced poultry diets is limited. However, recently developed new types of hybrid rye are characterised not only by increased yield potential, resistance to fungus and pests and low production costs, but also the content of antinutritive substances may be reduced in these varieties. The aim of this paper is to discuss the mechanisms of NSP effects in the digestive tract, as well as to review the results of recent studies on the use of rye in poultry nutrition. Based on the literature data, it can be concluded that the use of new hybrid rye varieties with decreased NSP concentration and NSP-hydrolising enzymes may be a way of increasing the share of rye grain in poultry diets.
