تعیین پلی ساکاریدهای غیر‌نشاسته‌ای و انرژی قابل سوخت‌وساز حقیقی برخی از واریته‌های گندم استان آذربایجان شرقی

The aim of this experiment was to determine non-starch polysaccharides and true metabolizable energy of five wheat varieties (alvand, zarrin, sabalan, sardari and azar2). non-starch polysaccharides of wheat varieties were measured with englyst method by spectrophotometer. nitrogen corrected true metabolizable energy of five wheat varieties was also determined with sibbald precision feeding method. a completely randomized design with 24 roosters (ross 308) at the age of 5 month was used in this experiment. the result of nsp content showed the total nsp, insoluble nsp and soluble nsp varied of 9.44 to 11.96 %, 7.10 to 9.40 % and 1.95 to 3.15 % dm, respectively. the highest total nsp value (11.96%) and insoluble nsp value (9.40%) were found in aza2 variety, and the highest soluble nsp value (3.15%) was found in alvand one. the lowest total nsp (9.44%) and soluble nsp (1.95%) values were resulted of sabalan variety, and the lowest insoluble nsp (6.94%) was resulted of zarrin variety. the tmen content of wheat varieties varied from 3562.32 kcal/kg (sabalan variety) to 3741.64 kcal/kg (zarrin variety), and tmen content showed significantly differences as wheat varieties (p < 0.01). this experiment demonstrated that the metabolizable energy content of east azerbaijan wheat varieties have a high variation and relative to method of cultivation.
