“…On the other hand, Reda et al (2022) found that addition of rice protein concentrate (RPC) reduced microbial diversity regardless of RPC content and that RPC-enriched diets resulted in greater relative abundance of Bacteroidetes and Fusobacteria in the intestine of Oreochromis niloticus compared to the intestine of the control fish. However, replacing more than 25% fishmeal with RPC can have deleterious effects on fish.…”

The study evaluated the effects of dietary supplementation with Lippia sidoides essential oil on the microbiota and intestinal morphology of Danio rerio . For this, 448 fish were randomly distributed in 28 tanks divided into a control group fed a commercial diet without supplementation, a group fed a commercial diet containing grain alcohol and five groups fed a commercial diet containing essential oil of L. sidoides (LSEO) at concentrations of 0.25%, 0.50%, 0.75%, 1.00% and 1.25%. After the period of dietary supplementation, biological materials were collected for microbiological and histological analyses. There were no significant differences regarding the microbiological count between the groups. Diversity of the microbiome was higher in 0.25% group than in control group. LSEO inhibited the growth of potentially pathogenic bacteria. Fish fed LSEO 0.25% showed greater intestinal histomorphometric indices. The inclusion of LSEO at 0.25% in the diet of D. rerio provided improvements in fish microbiota and intestine integrity.

“…Moreover, total counts of intestinal aerobic heterotrophic bacteria and coliform in fish fed with diets containing 100 or 190 g kg −1 of CPC were significantly lower than those in fish fed with diets containing 0 or 50 g kg −1 of CPC [ 26 ]. Diets containing rice protein concentrate as a replacement for fish meal protein changed the composition of the microbial community, decreased the microbial diversity, and increased the relative abundances of Bacteroidetes and Fusobacteria in the intestine of Nile tilapia [ 27 ].…”

The homeostasis of the intestinal microbiota of fish is beneficial to fish health, while food can affect the intestinal microbiota. Tilapia (Oreochromis spp.) has great economic value and is a good model to use in studying the digestion and absorption of nutrients. Furthermore, at present, due to a high demand and high price of high-quality feed raw materials, the nutritional composition of aquafeeds has been changing dynamically. There has yet to be a comprehensive review of research conducted on the influences of dietary macronutrients (proteins, lipids, and carbohydrates) on the tilapia intestinal microbiota. Therefore, this review focuses on the effects of dietary macronutrients on the gut microbiota of tilapia. Interestingly, we found that the best growth performance might not represent the best composition or functions of the gut microbiota. Overall, the unscientific addition of macronutrients to feed is harmful to the intestinal microbiota. Therefore, both growth performance and gut microbiota should be considered when evaluating certain macronutrients. It is our hope that this review will aid in regulating the intestinal microbiota of fish through nutritional means, thereby promoting tilapia farming.

“…Loureiro (2019) estudou os efeitos da inclusão do concentrado proteico de farelo de arroz para jundiás (Rhamdia quelen), concluindo que o mesmo pode ser utilizado em 20-30% em substituição a proteína advinda da farinha de peixe. Já para tilápia (Oreochromis niloticus), pesquisadores demonstram que essa substituição pode ser de até 25% (Reda et al, 2022). Esses resultados apontam potencial de utilização do concentrado proteico de quirera de arroz, em especial para espécies onívoras, que aceitam uma ampla gama de ingredientes nas rações.…”

O trabalho teve o objetivo de aplicar tecnologias para obtenção de concentrado energético (maltodextrina) e concentrado proteico (CPA) a partir da quirera de arroz. Inicialmente, a quirera de arroz foi moída, sendo submetida a pré-gelatinização, onde 100 g da matéria prima foi suspensa em água e submetida a aquecimento de 90°C sob agitação constante (30 minutos). Nela foram testados volumes crescentes de amilase (250, 350, 450, 550, 1000 e 2000 µL), visando a maior interconversão do amido em maltodextrina. Posterior à adição, a reação seguiu por mais 30 minutos e após foi filtrada em peneira de malha de 150 mícron. A fração sólida retida na peneira foi pesada e seca em estufa de circulação de ar (50ºC/24 horas), obtendo o concentrado proteico de arroz. Para obtenção da maltodextrina, a fração líquida foi seca em Spray dryer (120ºC e vazão de 1L/hora). Nos produtos obtidos, determinou-se proteína bruta e rendimento, além de cálculo de viabilidade econômica. Os resultados demonstraram que o uso de 250 µL de amilase é recomendado, por resultar em rendimento adequado (65,02%) de maltodextrina e teores aceitáveis de proteína bruta (21,64%). A técnica empregada tem custo reduzido, possibilitando a obtenção de dois produtos inovadores que poderão ser usados em estratégias nutricionais para distintas espécies e fases de desenvolvimento animal, ao mesmo tempo que fortalecerá a integração e a sustentabilidade econômica das cadeias produtivas do arroz.
