Effects of enzyme complex SSF (solid state fermentation) in pellet diets for Nile tilapia

Abstract

-The effects of enzyme complex SSF (solid state fermentation) on growth performance and the availability of sucrose and monosaccharides in the chyme of Nile were involved. The study included 360 fish (70g±4.43) in a completely randomized design with six dietary treatments (0, 50, 100, 150, 200 and 250 ppm of SSF) arranged in six replicates, with 10 fish per replicate. Every 15 days, one tilapia of each experimental unit was sacrificed for analyses of carbohydrate in the chyme. On day 60 of the experiment, the performance parameters were measured. There was a linear effect according to treatment for final weight and weight gain. For the other performance parameters, there were no differences. There was quadratic effect for sucrose and glucose in function of the treatment, whereas the fructose levels increased linearly. The addition of 150 ppm of the enzyme complex SSF in the feed improves the performance of Nile tilapia and increases the availability of sucrose and monosaccharides in the chyme.

Exogenous enzymes in diets for broilers

“…Basically, this type of additive uses fermentation in solid extracts conducted by specific fungi as an enzyme-production mechanism (ROBSON & NIGAN, 2003). This results in the fabrication of a complex with, according to the substrate used in the making, a natural specific combination of enzymes and a greater spectrum of action (MOURA et al, 2012), in addition to the low final cost, which facilitates its addition to broiler rations. In light of this, this study aimed at evaluating the performance, the carcass yield and the carcass parts, and the quality of the meat for broilers that were submitted to the diets based on corn and soybean meal with different levels of the SSF (solid state fermentation) enzyme complex.…”

Utilização De Enzimas Exógenas Na Nutrição De Peixes - Revisão De Literatura

“…Atualmente, pesquisas avaliando a inclusão de complexos enzimáticos, em rações para peixes à base de grãos com baixa viscosidade (milho e farelo de soja), tem observado resultados positivos no desempenho destes animais possibilitando uma utilização eficiente do amido e proteína (MOURA et al, 2012).…”

“…Por outro lado, em dietas para Catfish Africano (Clarias gariepinus), suplementadas com o complexo enzimático composto por: xilanase, pentonases, amilase, hemicelulase, celulase, pectinases, celubiase e β-glucanase; foi observado que os animais alimentados com ração contendo o complexo enzimá-tico obtiveram melhor conversão alimentar (P<0,05) quando suplementadas nos níveis de 0,05% e 0,075% (YILDIRIM; TURAN, 2010). De maneira similar, Moura et al (2012) verificaram que em dietas para Tilápia do Nilo, a suplementação com complexo enzimático melhorou o peso final e ganho em peso dos animais.…”

“…Como já relatado anteriormente, as enzimas são aditivos eficientes na redução de fatores antinutricionais possibilitando aumento da digestibilidade das rações (GUI- MOURA et al, 2012).…”

“…Os resultados obtidos podem ser justificados devido ao melhor aproveitamento energético do alimento, contribuindo para que a proteína não seja desviada para produção de energia e, por isso, seja mobilizada de forma eficiente para a formação de tecidos (MOURA et al, 2012).…”
