In Europe, wheat is commonly used in broiler diets. The chemical composition and energy value of wheat can vary considerably between different wheat cultivars or due to different growing and post-harvest storage conditions. The current study assessed the chemical composition in 153 batches of wheat used for poultry feeds from 15 European countries over 5 years of harvest. The non-starch polysaccharide (NSP)-composition, the concentration of starch and protein and the extract viscosity were analysed. The concentration of starch and protein ranged between 558 and 680g/kg dry matter (DM) and 92 and 173g/kg DM respectively. The concentration of water-extractable (WE) and water-unextractable (WU) NSP ranged between 8.7 and 18.3 and 58.1 and 99.6g/kg DM respectively. The variation was the largest in the WE fraction of the NSP (CV 14.3%). The concentration of WE-NSP was positively correlated with extract viscosity (r=0.46; P<0.001) and this was caused by the WE-arabinoxylan fraction (r=0.59; P<0.001) in particular. In conclusion, the present results confirm the variable composition of European wheat batches, especially for the WE-fraction of the NSP and highlight the need for considering the concentration of NSP in the practice of feed formulation.
