“…gariepinus., Kumar et al (2006) in Labeo rohita, Lin et al (2007) in Oreochromis niloticus × Oreochromis aureus; Zhou et al (2013) in Ctenopharyngodon idella. Increased endogenous enzyme activities lead to increased apparent nutrient digestibilities in Labeo rohita due to dietary exogenous enzyme, which is consistent with the findings of Ogunkoya et al (2006), who also found that exogenous enzyme supplementation to the soybean meal based diet improves the apparent digestibility coefficient of dry matter, protein, lipid and carbohydrate in Oncorhynchus mykiss. This is confirmed by many workers while working with other sp.…”

A 60-day feeding trial was conducted to study the nutrient utilization and growth performance of Labeo rohita fed with T1 [DORB supplemented with phytase and xylanase (0.01% each)], T2 [ T1+ L-lysine(1.4%), L-methionine (0.4%), combination of EPA and DHA (0.5%)] , T3 [DORB supplemented with phytase (0.01%), combination of xylanase and cellulase (0.075%), L-lysine (1.4 %), L-methionine (0.4 %), combination of EPA and DHA (0.5%)] and T4 (commercially available carp feed) diets. Weight gain%, SGR, and FCR were similar (p>0.05) for the fishes fed with either T3 feed or commercial carp feed (T4), whereas PER was highest for the T3 group. A significantly higher apparent dry matter and carbohydrate digestibility were observed in the T3 group. Highest crude protein digestibility was observed in T4 group, though lipid digestibility was similar in both T3 and T4 groups. The activities of digestive enzymes were similar in T2, T3 and T4 groups, whereas the lowest activity of these enzymes were observed in T1 group. Based on the findings it is concluded that T3 feed (crude protein 18.18 %) is having comparable growth performance of Labeo rohita as compared to T4 diet (crude protein 32.01 %) due to higher In vivo digestibility.

“…Recently, plant proteins such as soybean meal, cottonseed meal, and rapeseed meal have become the main protein sources in aquatic feeds due to the cost and shortage of animal protein resources (Hardy 2010). However, the utilization of plant proteins is usually limited because of the high content of anti-nutritional factors, non-starch polysaccharides (NSP), and crude fiber (Ogunkoya et al 2006). Meanwhile, high amount of plant proteins in aquatic feeds usually leads to the depressed growth performance and severe environmental pollution (Gatlin et al 2007).…”

This study was conducted to evaluate the effect of enzyme-treated soy protein (ETSP) supplementation in the low-protein diet on growth performance, digestive and absorptive capacities, and related signaling molecules' gene expressions in juvenile Jian carp. The results showed that percent weight gain (PWG), specific growth rate (SGR), and feed intake (FI) were decreased by reducing dietary protein from 34 to 32% (P < 0.05). Supplying low-protein diet with optimal ETSP increased previously mentioned indices of juvenile Jian carp (P < 0.05), which also had no significant difference with the high-protein diet (34%CP) (P > 0.05). Compared with the low-protein diet, appropriate ETSP supplementation in the low-protein diet increased (P < 0.05) (1) the trypsin, lipase, and amylase activities in the hepatopancreas; (2) cholecystokinin concentration in the proximal intestine; (3) the γ-glutamyl transpeptidase (γ-GT), alkaline phosphatase (AKP), and Na + /K + -ATPase activities in all intestinal segments; and (4) the messenger RNA (mRNA) levels of trypsin, lipase, and amylase in hepatopancreas and γ-GT in the mid (MI) and distal (DI) intestine, alkaline phosphatase in MI, and Na + /K + -ATPase and target of rapamycin in all intestinal segments. At the same time, appropriate ETSP supplementation in the low-protein diet downregulated the mRNA levels of AKP in the DI and eIF4E-binding protein 2 in all intestinal segments (P < 0.05). In conclusion, adding 10 g ETSP/kg diet in the low-protein diet can restore the growth performance and digestive and absorptive abilities to the levels in group with 34% dietary protein. Supplementation of optimal ETSP in the low-protein diet enhanced the digestive and absorptive abilities and regulated the signaling molecules related to the TOR signaling pathway.

“…Portanto, é muito importante a definição das concentrações dietéticas de fibra bruta adequadas para cada espécie de peixe e a determinação de sua composição. Ogunkoya et al (2005) também verificaram efeito positivo sobre os coeficientes de digestibilidade aparente de MS, PB, lipídeo, fósforo e energia ao estudarem a incorporação de farelo de soja e de um complexo enzimático composto por xilanase, amilase, celulase, protease e β-glucanase à dieta de truta arco-íris (Oncorhynchus mykiss). Todavia, Stone et al (2003) utilizaram complexo enzimático composto pelas enzimas β-glucanase e β-xilanase, específicas para PNA, em rações para Silver Perch (Bidyanus bidyanus) e não observaram efeito sobre a digestibilidade aparente de matéria seca, energia ou proteína.…”

RESUMO -Um ensaio de digestibilidade foi conduzido para avaliar os efeitos da suplementação de ração com um complexo enzimático contendo celulase, protease e amilase sobre a digestibilidade dos nutrientes em juvenis de tilápia-do-nilo (Oreochromis niloticus). As rações experimentais eram isoprotéicas (30% PB), isoenergéticas (4.243 kcal/kg EB) e foram suplementadas com complexo enzimático comercial contendo celulase, protease e amilase nos níveis de 0,0; 0,025; 0,050; 0,075 e 0,1%. A determinação da digestibilidade aparente foi realizada pelo método indireto, com uso de óxido de cromo (Cr 2 O 3 ) como indicador de digestibilidade. Foram utilizados 50 juvenis machos de tilápia-do-nilo (90 ± 15 g) distribuídos aleatoriamente em dez incubadoras adaptadas para ensaio de digestibilidade. O experimento foi conduzido em três períodos experimentais, com cinco tratamentos e duas repetições por período. A adição do complexo enzimático à ração melhorou o coeficiente de digestibilidade aparente de matéria seca, proteína bruta, energia bruta, amido, cácio e fósforo. Entre os níveis testados, o de 0,05% de complexo enzimático proporcionou os valores mais expressivos. Palavras-chave: enzimas exógenas, Oreochromis niloticus, piscicultura Nutrient digestibility in diets with enzyme complex for Nile tilapiaABSTRACT -A digestibility trial was conducted to evaluate the effects of the supplementation of the ration with a enzyme complex containing cellulase, protease and amylase on the digestibility of nutrients in Nile tilapia juveniles (Oreochromis niloticus). The experimental diets were isoprotein (30% CP), isoenergy (4,243 kcal/kg of GE) and supplemented with a commercial enzyme complex containing cellulose, protease and amylase at the levels of 0.0, 0.025, 0.050, 0.075, and 0.1%. The apparent digestibility was determinated by the indirect method using chrome oxide (Cr 2 O 3 )as an indicator of digestibility. A total of 50 male Nile tilapia juveniles (90 ± 15 g) were randomly allotted to ten hatchers adapted for the digestibility trial. The experiment was conducted in three experimental periods, with five treatments and two replicates per period. The addition of the enzyme complex to the diet improved the apparent digestibility coefficient of dry matter, crude protein, gross energy, starch, calcium and phosphorus. Among the tested levels, the 0.05% of enzyme complex provided the most expressive values. Key Words: fishculture, exogenous enzymes, Oreochromis niloticus IntroduçãoProgramas alimentares eficientes e a máxima utilização dos nutrientes alimentares são a principal preocupação da piscicultura diante da alta demanda mundial de pescados a curto e médio prazos.Os ingredientes de origem vegetal mais utilizados em dietas para não-ruminantes são relativamente ricos em amido e proteína, mas contêm nutrientes não digeríveis presentes na parede celular, como os polissacarídeos não-amiláceos (PNAs), os oligossacarídeos e outros não-carboidratos (glicoproteínas, ésteres fenólicos, lignina). A hemicelulose também não é totalmente dige...
