“…Nowadays, the use of oils and oilseeds in animal feed has been considered by researchers due to numerous biological roles. Reducing energy demand in livestock by reducing milk fat at the beginning of lactation by certain fatty acids [ 5 , 6 , 7 ], increasing the nutrition of carbohydrates and fats to meet the metabolic needs of livestock [ 8 , 9 ], and the tendency to increase the concentration of conjugated linoleic acid in livestock products due to its effects on human health [ 10 , 11 , 12 ] can be cited as some of the reasons for this approach. However, when unprotected oils are fed to cows, there is an extensive hydrolyzation and biohydrogenation by ruminal microorganisms that results in marginal increases in passage to intestine [ 13 ].…”

The aim of this study was to investigate the effect of using chitosan nanoparticles and calcium alginate in the encapsulation of flaxseed oil on the biohydrogenation of unsaturated fatty acids and in vitro fermentation. The experiments were performed in a completely randomized design with 7 treatments. The experimental treatments included: diets without oil additive (control), diet containing 7% flaxseed oil, diet containing 14% flaxseed oil, diet containing 7% oil encapsulated with 500 ppm chitosan nanocapsules, diet containing 14% flaxseed oil encapsulated with 1000 ppm chitosan nanocapsules, diet containing 7% of flaxseed oil encapsulated with 500 ppm of calcium alginate nanocapsules, diet containing 14% flaxseed oil encapsulated with 1000 ppm calcium alginate nanocapsules. The results showed that encapsulation of flaxseed oil with calcium alginate (14%) had a significant effect on gas production (p < 0.05). The treatment containing calcium alginate (14%) increased the digestibility of dry matter compared to the control treatment, but the treatments containing chitosan caused a significant reduction (p < 0.05). The results indicated that the percentage of ruminal saturated fatty acids decreased by encapsulation of flaxseed oil with chitosan (14% and 7%). The percentage of oleic unsaturated fatty acid by encapsulating flaxseed oil with chitosan (14%) had a significant increase compared to the control treatment (p < 0.05). As a result, encapsulating flaxseed oil with chitosan (14%) reduced the unsaturated fatty acids generated during ruminal biohydrogenation.

“…Furthermore, soybean meals and other vegetable ingredients introduce anti-nutrients, giving rise to a number of problems for the fish such as enteritis and reduced nutrient uptake and bioavailability (Baeverfjord and Krogdahl 1996;Kaushik et al 1995;Storebakken et al 1998). This can be offset-at least to a certain point-by refining the plant protein sources (Glencross 2016;Jia et al 2022;Naylor et al 2009;Refstie et al 2005), which, however, introduces costs and results in a trade-off between fish welfare/health and feed cost. Other alternative protein and oil crops such as pea, rapeseed and lupines proved to be suitable for fish feeds (Burel et al 2000b;Glencross et al 2011;Omnes et al 2015;Øverland et al 2009;Zhang et al 2012).…”

Sustainable fish feeds: potential of emerging protein sources in diets for juvenile turbot (Scophthalmus maximus) in RAS

et al. 2022

In Europe, turbot aquaculture has a high potential for sustainable production, but the low tolerance to fishmeal replacement in the diet represents a big issue. Therefore, this study investigated the effects of more sustainable feed formulations on growth and feed performance, as well as nutritional status of juvenile turbot in recirculating aquaculture systems. In a 16-week feeding trial with 20 g juvenile turbot, one control diet containing traditional fishmeal, fish oil and soy products and two experimental diets where 20% of the fishmeal was replaced either with processed animal proteins (PAP) or with terrestrial plant proteins (PLANT) were tested. Irrespective of diets, growth performance was similar between groups, whereas the feed performance was significantly reduced in fish of the PAP group compared to the control. Comparing growth, feed utilisation and biochemical parameters, the results indicate that the fish fed on PAP diet had the lowest performance. Fish fed the PLANT diet had similar feed utilisation compared to the control, whereas parameters of the nutritional status, such as condition factor, hepato-somatic index and glycogen content showed reduced levels after 16 weeks. These effects in biochemical parameters are within the physiological range and therefore not the cause of negative performance. Since growth was unaffected, the lower feed performance of fish that were fed the PAP formulation might be balanced by the cost efficient formulation in comparison to the commercial and the PLANT formulations. Present study highlights the suitability of alternative food formulation for farmed fish.

“…Таким образом, протеиновые концентраты являются перспективным видом кормового сырья. Но из-за высокой стоимости их производства, применение концентратов раститель-ного белка в настоящее время еще не является полностью экономически целесообразным, поэтому они мало используются в качестве кормовых ингредиентов в аквакультуре [14].…”

“…Еще одним потенциальным видом сырья для аквакультуры с высоким содержанием белка является клейковина (глютен), получаемая при переработке зерна пшеницы, кукурузы и других зерновых культур и содержащая 60-65 % протеина с хорошим аминокислотным профилем [8,14]. Результаты исследований показывают, что глютен может быть включен в корма для рыб в качестве замены рыбной муки самостоятельно либо совместно с вышеописанными видами растительного сырья [4,6].…”

“…Так, V. I. Kaur В целом можно сделать вывод, что достоинства и недостатки шротов (низкая стоимость, но содержание антипитательных факторов) и белковых концентратов (отсутствие вредных веществ, но высокая цена) позволяют достигать хороших результатов при их совместном использовании в составе кормов для рыб, что подтверждают результаты некоторых исследований [14,47,48].…”

Rising prices of traditional feedstock for feed preparation (fish meal and oil) is a problem for aquaculture enterprises. Their replacement with inexpensive components of vegetable origin is the way for solving the problem. The aim of the study is to generalize and analyze scientific data on using new types of vegetable feedstock in aquaculture feeds, on technologies of their preparation and use, influence on feed quality. Selection and systematic review of scientific literature on the topic of the study for the period of 2017-2022 has been carried out. The derivatives of land agricultural plant products such as oilseed meal, protein concentrates, gluten and food industry wastes are the main types of vegetable feedstock for feed preparation in aquaculture. Currently, vegetable oils are the best variants for replacing fish oil in fish diets. Partial or complete replacement of fishmeal and oil with new types of vegetable feedstock is possible and does not lead to deterioration of fish health and growth rate when these components are included in the diet at recommended doses. Such a replacement is economically advantageous. But there are negative effects in the use of vegetable feedstock, such as the presence of anti-nutritional factors that limit its use in aquaculture. The development of recipes of cost-effective fish feeds in which fish meal and oil are completely replaced by vegetable components is a research priority for the development of intensive aquaculture.
