The results of the studies discussed indicate practical possibilities for increasing the nutritional value and range of fodder utilisation of rapeseed products by means of, among others: (i) further lowering GLS content to the level of 3 - 5 μM, permitting broader application of raw seeds and better utilisation of press cake obtained during cold pressing of oil; (ii) modification of the traditional technology of rapeseed processing, mainly through lowering the temperature of seed conditioning and rapessed meal toasting, which bring about lysine loss and increase the biological value of protein; (iii) reducing fibre content in rapeseed meal (through hulling of seeds, fractioning of rapeseed meal) and selection of ‘000’ cultivars, permitting an increase in energetic value of meal in feeding monogastric animals; (iv) optimisation of cold pressing of oil with regard to the nutritonal value of press-cake.

Na podstawie danych piśmiennictwa scharakteryzowano znaczenie produktów rzepakowych w bilansie paszowym Polski oraz wskazano możliwości zwiększenia wartości pokarmowej śruty poekstrakcyjnej oraz makuchów. W podsumowaniu pracy stwierdzono celowość, m. in., dalszego obniżenia zawartości glukozynolanów w nowych odmianach rzepaku (do poziomu 3 - 5 μM), zmodyfikowanie tradycyjnej technologii przetwórstwa nasion (obniżenie temperatury kondycjonowania nasion i testowania śruty poekstrakcyjnej) oraz optymalizację techniki tłoczenia oleju w olejarniach rolniczych, celem zwiększenia wartości pokarmowej uzyskiwanego makuchu.
