Nutritive value of Serbian camelina genotypes as an alternative feed ingredient

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 gtocopherols. 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 a-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.

Impact of Using Oilseed Industry Byproducts Rich in Linoleic and Alpha-Linolenic Acid in Ruminant Nutrition on Milk Production and Milk Fatty Acid Profile

“…Camelina (Camelina sativa) is an ancient plant which has been cultivated in the past; however, it has gained increasing popularity in the last decade thanks to its distinctive nutritional profile and agronomic attributes, which include adaptability to diverse environmental conditions, low fertilizer requirements, relatively short growing season, and good resistance to diseases and pests [26,27]. It has been considered a sustainable and renewable raw material for biofuel production due to its abundant oil content [28] and promising alternative ingredient in animal nutrition [29].…”

The influence of oil cake granulation and ultrasonic pretreatment on the properties of biopolymer films based on Camelina sativa oilseed cake

“…Large quantities of by-products (cake, meal) are left after oil extraction. These products have good potential to be used as a cheap alternative protein feedstuff and a valuable source in animal nutrition (Ilić et al, 2022;Rakita et al, 2023;Riaz, Ahmed, Sizmaz & Ahsan, 2022;Juodka et al, 2022). Ibrahim and El Habbasha (2015) reported that camelina meal contains ≈5.5% of sucrose, ≈1% of starch, less than 1% of pectin, 6.7% of mucilage, and 7.4% of lignin.…”

“…These camelina genotypes are wellsuited to the Balkan region's environmental circumstances and have good production qualities (Marjanović Jeromela et al, 2021;Čanak et al, 2022). The study of Ilić et al (2022) evaluated the nutritional value of two Serbian genotypes of camelina seed. Because they included a significant number of proteins, amino acids, and tocopherols as well as a moderate amount of minerals, the examined Serbian camelina seed genotypes displayed an outstanding nutritional profile (Ilić et al, 2022).…”

This work aimed to develop biopolymer composite films based on the agro-industrial byproduct camelina oilseed cake and to examine the effect of the cake granulation on the properties of the obtained films.…”

Exploring the nutritional potential of Camelina sativa genotypes: A study on minerals and bioactive compounds

“…Besides being used for bio-diesel production, its exceptional oil composition and valuable properties make camelina a candidate for utilization in food and feed production, as well as a range of non-food products (Berti et al, 2016;Fröhlich & Rice, 2005). Camelina can be used to improve the quality of food and feed due to its chemical composition (Abramovič et al, 2007;Ghidoli et al, 2023;Ilić et al, 2022). The high protein content, alongside the well-balanced fatty acid composition and valuable bioactive compounds in camelina seeds, not only holds nutritional significance but also offers multiple health benefits.…”
