The effect of feeding with hemp and Camelina cakes on the fatty acid profile of duck muscles

Abstract

Abstract. Camelina (Camelina sativa L. Crantz) and hemp (Cannabis sativa L.) seed cakes are rich sources of n-3 polyunsaturated fatty acids (PUFAs). This study was carried out to investigate the effects of Camelina and hempseed cakes in the diet of ducks on the intramuscular fatty acid profile. Male ducks (n = 99) were randomly allocated to 3 dietary treatments: Control or C group (wheat-soybean-meal-barley-based diet with 15-20 % rapeseed cake), Experimental 1 or HEM group (with hempseed cake added at 15-20 % instead of rapeseed cake), and Experimental 2 or CAM group (with Camelina cake added at 15-20 % instead of rapeseed cake). All groups received the diets ad libitum. At 49 days of age, six ducks from each group were slaughtered for analysis of the fatty acid composition in the breast and leg muscles.Feeding ducks with the diet enriched with Camelina cake resulted in significantly higher amounts of n-3 α-linolenic fatty acid (ALA) (P ≤ 0.01) and total n-3 PUFA (P ≤ 0.01) in breast and leg muscles, while eicosatrienoic fatty acid (ETE) (P ≤ 0.01) was higher in the leg muscle. The ratios of n-6 / n-3 and linoleic / α-linolenic fatty acids (P ≤ 0.01) decreased significantly compared to the Control and HEM groups of ducks.Feeding ducks with the diet enriched with hempseed cake resulted in significantly higher amounts of linoleic (LA) (P ≤ 0.01), total n-6 PUFA (P ≤ 0.05-P ≤ 0.01) and n-6 γ -linolenic (GLA) (P ≤ 0.01) fatty acid.Our study showed that using Camelina cake as supplementation in duck diets opens a possibility to develop functional food, i.e. meat with a significantly higher content of ALA, total n-3 PUFA and the lowest ratios of n-6 / n-3 fatty acids in ducks' muscles. A duck diet with hempseed cake produces exceptional-quality meat with an enriched content of n-6 GLA.

“…Fatty acid profile of camelina cake and diets. Table 2 shows that the fatty acid profile of camelina cake used in our study and obtained by cold-pressing oil extraction method, is a rich source of α-linolenic acid (ALA, 29.47%), linoleic acid (LA, 21.09%), and oleic acid (17.69%).Similar results have been reported previously by Nain et al (2015) and Juodka et al (2018). The fatty acid composition of diets showed that the inclusion of 80 g/kg CAMC increased the ALA content (2.87-fold) and resulted in a 3.89-fold decrease of the LA: ALA ratio, compared with the classical diet.…”

“…(2015) . The Σ PUFA n-6 / n-3 ratios determined in the present study for all geese muscles were higher than those previous obtained for duck meat by Wołoszyn et al., 2006 , Juodka et al., 2018 , and Onk et al. (2018) (3.3–5.1, 3.3–3.39, and 5.0).…”

“…(2015) for native Turkish geese reared with 4 different fattening systems (37.3–40.7%). Similarly, the breast muscles from different breeds of ducks were characterized by a higher (31–42%) percentage of SFA ( Wołoszyn et al., 2006 , Juodka et al., 2018 ).…”

“…Furthermore, it has been also observed that among, n-6 PUFAs, the hempseed products supplementation led to an enrichment of eggs and meat with the GLA [150,161], conferring to these food products a further unique features related to the biological anti-inflammatory and anti-proliferative properties of GLA that have important implications for human health. Similar GLA-enrichment was also shown in the muscle of ducks fed a 15-20% hempseed cake-supplemented diet [162].…”
