Rapeseed meal is a valuable source of protein for animals feeding. It can be used as an alternative to soybean meal in the mixtures of combined feeds intended for farm animals. Thus, the purpose of this study was to evaluate the chemical and nutritional composition of the rapeseed meal intended for use in the feeding of monogastric livestock. 70 samples of rapeseed meal arrived at the Laboratory of Chemical Analyses for Animal Nutrition, were analysed. The following values were obtained for the main nutritional compounds: crude protein (CP) – 37.95%, with variations between 35.26 and 41.67%; ether extract (EE) – 1.84%, with values between 1.55 – 2.06%; crude fiber (CF) – 11.93%, with variations between 9.85 – 14.93%; and nitrogen-free extracts (NfE) – 41.07%, varying significantly between 35.75 – 45.82%. In order to evaluate the nutritional value of rapeseed meal, the digestible forms of nutrients and the value of metabolizable energy (ME) for pigs and poultry were calculated, using predictive formulas. The average ME value for pigs was 1278.57 kcal/kg, varying between 1145.63 - 1398.27 kcal/kg, and for poultry the ME value was 935.06 kcal/kg, being between 837.90 - 1022.55 kcal/kg. These data underline the importance of the chemical and nutritional evaluation of feed ingredients before they are included in the diets of farm animals in order to have the certainty of correctly calculated rations and to ensure the amounts of nutrients in accordance with their feeding norms, in order to maximize animal production.
