“…Two experimental diets (Table 1) were designed in order to evaluate the impact of brewer's SDY on gilthead sea bream growth and feed efficiency performance (Estévez et al, 2021), as well as evaluate global transcriptome changes in selected tissues (head kidney, anterior-mid intestine, and liver). A control diet was formulated containing 15% of FM and 46.7% of a blend of PP sources, whereas lipids were mainly provided by fish oil (7.9%), soybean oil (6.7%), and lecithin (2.0%).…”

“…Among them, Brewer's spent yeast (SDY), a by-product of the brewing industry, is a rich source of B vitamins, proteins (45-60%) and other compounds like β-glucans and mannoproteins (Jaeger et al, 2020;Agboola et al, 2021). Therefore, BSY is mainly utilized in animal feed formulations as a low-cost source of protein (Agboola et al, 2021;Estévez et al, 2021;Nazzaro et al, 2021) even though it may be also used as an ingredient in functional feeds due to its potential health benefits to the host (Jaeger et al, 2020). Under this scenario, Estévez et al (2021) have shown that the replacement of FM and plant protein sources by SDY in the feed of a carnivorous marine teleost fish species, the gilthead sea bream (Sparus aurata), resulted in a better growth, as well as a higher protein digestibility and feed efficiency indexes than in their congeners fed a reference diet.…”

The above-mentioned results showed that this by-product from the brewing industry is a promising feed ingredient in aquafeeds, especially when considering its use in terms of an alternative plant protein source, but also when considering its associated sustainable and environmental benefits.…”

“…Once validated the use of SDY as an alternative protein source in aquafeeds (Estévez et al, 2021), the present study aimed to evaluate at the transcriptomic level the impact of SDY in the head kidney, intestine, and liver of S. aurata. This marine species is the most important Mediterranean aquaculture fish species in terms of volume and economic value (FAO, 2020).…”

In this study, we evaluated the replacement of dietary protein sources like fishmeal (FM) and plant proteins (PP) by Brewer’s spent dry yeast (SDY) on the transcriptomic response (RNA-seq, NextSeq500 platform Illumina) in the liver, anterior-mid intestine, and head kidney in juveniles of gilthead sea bream (Sparus aurata). The inclusion of SDY at 30% in the experimental diet (40% crude protein, 16% crude lipid) resulted in a reduction in FM (10%) and PP (31.4%) contents. Using RNA-seq, a total of 19.4 million raw reads per library were obtained, from whose 99.8% of the sequenced data were retained. The alignment efficiency of uniquely mapped reads was 90.3, 89.5, and 89.8% for head kidney, liver, and anterior-mid intestine, respectively. In total, 218 differentially expressed genes (DEGs) were identified among all tissues, out of which, 141 were up- and 77 down-regluated. The enrichment analysis of DEGs revealed that SDY had a modulatory effect on several processes related to host’s immunity, oxygen’s carrier capacity, steroidogenesis, metabolism, and digestion. It is of special relevance the immunomodulatory effects of the tested ingredient as data from RNA-seq showed from the three target tissues analyzed. These results indicated that this ingredient in addition to being considered as a sustainable raw material for replacing conventional protein sources in aquafeeds may also be considered as a functional ingredient due to its content in β-glucans. The overall results of this study coupled with previous nutritional studies on this ingredient indicated the suitability of brewery’s by-products like SDY in aquafeeds for carnivorous species like gilthead seabream, as well as supporting a circular bioeconomy model that reuses, recovers, and recycles resources instead of producing wastes.

“…D. San Martin установил, что добавление дробины в корм для дорады (Sparus aurata) обеспечило хорошую переваримость белка [62]. A. Estévez также сообщает об эффективности включения дробины в рацион дорады в количестве до 30 %, при этом переваримость белка была на уровне 89-95 % [63]. Это позволяет заключить, что пивная дробина имеет высокий потенциал применения в качестве недорогого источника протеина для аквакультуры.…”

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.
