Abstract

Camelina has been used from ancient times, but recently has re-emerged as a valuable plant with the potential for successful replacement of conventional oilseed crops. The utilisation of camelina and its by-products in animal feed is a matter of scientific study due to their excellent nutritional potential. The present study aimed to investigate the nutritive value of two Serbian camelina seed genotypes (NS Zlatka and NS Slatka) as a potential alternative to commonly used oilseed crops in animal feeding. For that purpose proximate composition, fatty acid profile, amino acid profile and tocopherols were analysed. The study also included the investigation of the content of anti-nutritive compounds that can adversely affect the nutritional value of feed. The results showed that camelina seeds had a high amount of proteins (around 28%), amino acids and γ- tocopherols. Camelina genotypes were characterized by unique fatty acids composition, with its oil consisting of approximately 57% polyunsaturated fatty acids, of which the highest proportions were α-linolenic acid (~37%) and linoleic acid (~17%). An optimal ratio of n-6 and n-3 fatty acids (0.5) was also reported in this study. The concentration of anti-nutritional factors and heavy metals in camelina seeds was below the maximum set limit for feedstuff. To conclude, the investigated Serbian camelina genotypes can be used as a valuable source of proteins, essential fatty acids and tocopherols in animal nutrition and has a great potential to replace conventional oilseeds.
