Özet
Abstract Rapeseed belongs to the world's most important oilseeds. The nutritive value of rapeseed meal has gradually improved to the point where it has become an acceptable alternative to soybean meal as a source of protein in rations. The objectives of the present work was to assess the composition and mineral distributions of low and high erucic rapeseed cultivars. Ten varieties including a local one were examined for their proximate composition. The fat content ranged between 40.5 and 45.6 %, while the crude protein content varied from 24.3 to 28.2 % on dry matter basis. Mineral analysis were conducted on seeds after wet ashing of samples. Total phosphorus content was found to be between 0.60 and 0.84%, being nearly twice as compared to soybeans. Total sulphur, which predicts both the levels of S‐bearing amino acids and glucosinolates varied greatly, from 0.40 to 1.11%, in the examined rapeseeds. Important differences among the tested rapeseed cultivars were also valid for other minerals especially iron, manganese and calcium contents.
