“…Desta forma, fontes vegetais como os grãos e farelos energéticos e proteicos, vêm sendo incluídas e analisadas com intuito de aprimorar sua aplicação nas rações de peixes (Pianesso et al, 2021;Yu et al, 2021;Pretto, et al, 2020;Dalcin et al, 2018;Lovatto et al, 2017). Porém, deve-se considerar que o uso destas fontes gera competitividade com a produção de outras espécies zootécnicas consolidadas, como aves e suínos.…”

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.

In this study, Nile tilapia were fed a blend of oilseed meals (BOM) that includes cottonseed meal (CSM), linseed meal (LSM), sesame meal (SSM), and sunflower meal (SFM) at a ratio of 1 CSM: 1 LSM: 1 SSM: 1 SFM. Six diets were formulated where the first diet included FM and SBM as protein sources and considered the positive control diet (FM). Another five FM-free diets were formulated, where SBM was substituted with BOM and included at 0, 100, 200, 300, and 400 g/kg diet. After 90 days, the FBW, WG, and PER were markedly increased while FCR decreased by FM-based diet and BOM at 0, 100, or 200 g/kg compared to fish-fed BOM at 300, and 400 g/kg (P < 0.05). The groups treated with BOM at 100–200 g/kg demonstrated considerable impairments, followed by those treated with BOM at 300 g/kg. Furthermore, fish given BOM at 400 g/kg had significantly less intestinal histological characteristics than the other groups. The relative expression of the IGF-1, GHR1, FABP, and CCK genes were downregulated in tilapia-fed BOM at 200, 300, and 400 g/kg compared to fish-fed FM-based diet (P < 0.05). The relative cost of feed per kg fish gain showed 4.42, 7.11, 8.14, 10.32, and 8.10% reduction rates in fish-fed SBM, or BOM at 100, 200, 300, and 400 g/kg. In conclusion, dietary BOM can be incorporated in Nile tilapia diets at up to 200 g/kg without affecting growth performance or feed utilisation. High inclusion levels (300 and 400 g/kg) may impair growth performance and feed utilisation by disrupting intestinal histological characteristics and reducing expression of growth and metabolic genes (GHR1, IGF-1, FABP, and CCK) in the liver.

The linseed processing was carried out on a laboratory scale to obtain the linseed protein concentrate (LPC), using the physical method. The analyzes were carried out on whole grains (WG), demucilated grains (GD) and LPC. In the fractions obtained, the chemical composition (dry matter, ash, lipids, crude protein, total dietary fiber, soluble fiber and insoluble fiber), total phenolic compounds and physicochemical properties were evaluated in the obtained fractions. The amino acid profile was determined for WG, GD and LPC. Protein molecular weight electrophoresis was determined for WG, GD and LPC. The results indicated that, in the physical process for protein concentration, LPC presented a protein content 96% higher than that of linseed grains and obtained less than 8% of lipids in its composition. Furthermore, LPC improved the amino acid profile and at the phenolic compounds of the different fractions of flaxseed, we see that their contents were concentrated in the LPC, which was 83.75% higher than the WG. The electrophoresis results demonstrate that physical processing caused a reduction in the molecular weight of the reducing and non-reducing flaxseed proteins. The present study allows us to conclude that it is possible to separate flaxseed into different fractions, using physical processes, obtaining a protective concentrate. The inclusion of these products in animal feed needs to be evaluated to determine levels of acceptance.
