Rapeseed toasted shale is a valuable source of high quality feeding protein (up to 37-43% of valuable protein) which is well-balances in amino acids; it has a high feeding power and digestiblity. In the level of amino acids content, mainly essential amino acids rapeseed is close to soy. Bioavailability of rapeseed protein is 86%. Due to a high content of protein and sulfur-containing amino acids rapeseed shale can be successfully used in the production of feeding compounds with the balanced amino acids content and functional purpose. In energy value (10,4 MJ of metabolizable energy) rapeseed shale is as good as sunflower shale (10,6 MJ, respectively). In the content of calcium, phosphorus, magnesium, copper and manganese rapeseed cake and rapeseed shale exceed soy ones. Calcium availability in them is 68%, phosphorus availability is 75%, magnesium availability is 62%, manganese availability is 54%, copper availability y is 74%, zinc availability is 44%. Rapeseed shale contains high quantities of choline, niacin, riboflavin, folic acid and thiamin.
