The purpose of the study was to investigate the effects of dietary hempseed or camelina cakes on the fatty acid profiles of intramuscular fat in quail. A total of 189 one-day-old quail were allocated to three dietary treatment groups. The diet of the control (C) group was supplemented with 10% rapeseed cake, whereas the rapeseed in experimental 1 (HE) and experimental 2 (CA) groups was replaced by, respectively, hempseed cake and camelina cake in the same proportions. The length of the study was 42 days. Dietary enrichment with camelina cake increased the α-linolenic fatty acid (ALA) content in the meat of CA group 2.5 times (p < 0.01). The muscle tissues of CA contained 3.4–3 times more eicosapentaenoic acid (p < 0.01), 1.2 times more docosapentaenoic acid (p < 0.05–p < 0.01) and 1.3 times more docosahexaenoic acid (p < 0.01) and, thus, demonstrated the increase in total long chain (LC) n-3 polyunsaturated fatty acids (PUFA) (p < 0.01) and total n-3 PUFA (p < 0.01) compared with the C group. The ALA and total n-3 PUFA content in the breast and leg meat of HE-treated quail were, respectively, 1.3 and 1.1 times higher (p < 0.01) than in the C group but the accumulation was lower compared to the CA group. The content of γ-linolenic acid was found to be 1.21–1.31 times higher in HE quail meat (p < 0.01). However, hempseed cake supplementation had a negative effect on growth performance. The supplementation of quail feed with camelina or hempseed cakes resulted in the production of healthy meat with an increased n-3 PUFA content.
