“…Rondán et al 2004) tolerate 60% of soybean meal in their diet with no serious negative effects, aside from the need to increase feed consumption in order to attain similar growth values (Hernández et al 2007). Chatzifotis et al 2008 studied the effect of partial substitution of fishmeal by soy protein concentrate (0%, 25%, and 40%) with taurine supplementation in juvenile dentex, and concluded that partial substitution of fish meal is possible with 25% of soybean concentrate without affecting growth, which can be improved further by dietary taurine supplementation of 2 g · kg -1 diet.…”

Tomás A., Martínez-Llorens S., Jover M. 2009. The effect of dietary soybean meal on growth, nutrient utilization efficiency, and digestibility of juvenile common dentex, Dentex dentex (Actinopterygii: Perciformes: Sparidae). Acta Ichthyol. Piscat. 39 (1): 19-25.Background. The aim of this work was to study the growth of juvenile dentex fed on cooking-extruded diets, determine the level of substitution of fishmeal by soybean meal may be without affecting the growth in this species and its digestibility. Materials and Methods. The availability of defatted soybean meal as a substitute for fish meal was evaluated in juvenile (41 g on average) dentex by feeding diets containing 0%-60% soybean meal, for 97 days.Results. Survival at the end of the experiment was high (80%) except for the fish fed diets with 50% and 60% substitution. Growth, feed gain ratio, and protein efficiency ratio (PER) were slightly reduced at higher soybean meal levels. Fish fed diets containing 0% to 40% of soybean meal grew significantly more and FCR was lower than fish fed other diets. No differences were obtained for protein digestibility coefficients of experimental diets (20%, 30%, 40%, and 50% SBM). Conclusion.The results confirm the best protein level for optimum growth seems to be around 50% and 12% lipid level, and maximum soybean meal substitution of 40%.

“…Resultados semelhantes foram obtidos com várias espécies de peixes, com relatos de que a suplementação de taurina em dietas práticas à base de farinha de peixe aumentou o desempenho produtivo de linguado japonês, Paralichtys olivaceus (Kim et al, 2005), robalo-europeu, Dicentrarchus labrax (Martinez et al, 2004), pargo-japonês, Pagrus major (Matsunari et al, 2008), e dentex-comum Dentex dentex (Chatzifotis et al, 2008). Resultados semelhantes aos deste estudo foram observados em juvenis do camarão-tigre (Penaeus monodon), que também se beneficiaram com a suplementação de 8 g/kg de taurina em dietas semipurificadas à base de caseína e pequena quantidade de farinha de camarão, melhorando significativamente os índices de crescimento e conversão alimentar (Shiau & Chou, 1994).…”

“…Dessa forma, o efeito promotor de crescimento em muitos estudos está provavelmente relacionado às ações secundárias ou auxiliares da taurina em outros fenômenos biológicos (Martinez et al, 2004;Chatzifotis et al, 2008). De acordo com Huxtable (1992), entre as numerosas funções fisiológicas em que está envolvida, a taurina é um composto muito importante no metabolismo de lipídios, pois atua como o único aminoácido conjugador de sais biliares em peixes teleósteos, formando os ácidos taurocólico e taurochenodeoxicólico (Goto et al, 1996;Kim et al, 2007), que agem na solubilização ou emulsificação de gorduras, tornando-as mais acessíveis para a digestão (Huxtable, 1992;Chatzifotis et al, 2008).…”

Em peneídeos, Shiau & Chou (1994) obtiveram melhora no desempenho de camarão-tigre, Penaeus monodon, com a suplementação de taurina na dieta, entretanto, não há na literatura relatos sobre a suplementação de taurina em dietas para L. vannamei.…”

RESUMO -Este estudo foi realizado com o objetivo de avaliar a possibilidade de reduzir a concentração proteica da dieta para pós-larvas de camarão-branco-do-pacífico (Litopenaeus vannamei) por meio da suplementação do aminoácido taurina.Seis dietas práticas, isoenergéticas (15,48 kJ EM/g), foram formuladas para conter duas concentrações de proteína (35% e 45% proteína bruta, PB), com três níveis de suplementação de taurina (0, 5 e 10 g/kg), em arranjo fatorial 2 × 3, com quatro repetições.Cem pós-larvas (peso inicial de 0,14 ± 0,01 g) foram estocadas em cada um dos 24 tanques de 45 litros conectados a um sistema de recirculação de água marinha. As dietas experimentais foram distribuídas aos camarões (10% da biomassa) três vezes ao dia, durante 30 dias. A concentração proteica da dieta não influenciou o crescimento nem a utilização alimentar das pós-larvas, mas o efeito benéfico da suplementação das dietas com taurina foi evidente em ambos os níveis proteicos testados. As pós-larvas alimentadas com as dietas com maior concentração de taurina (10 g/kg) alcançaram maior peso final, ganho em peso e taxa de crescimento específico e melhor conversão alimentar em comparação àquelas alimentadas com as demais dietas. A taxa de sobrevivência média foi superior a 92% e não foi afetada pelas dietas experimentais. O nível de 35% de PB na dieta (22,58 mg PB/kJ EM) é suficiente para promover o crescimento adequado de pós-larvas de L. vannamei, e o desempenho dos camarões pode ser melhorado com a suplementação de 10 g taurina/kg de ração.Palavras-chave: aminoácido, camarão, dieta prática, nutrição, proteína Taurine supplementation of diets with two protein concentrations to Pacific white shrimp post-larvae ABSTRACT -The present study aimed to evaluate the possibility of reducing the dietary protein content for post-larvae of Pacific white shrimp (Litopenaeus vannamei) through diet supplementation with taurine amino acid. Six practical isoenergetic (15.48 kJ ME/g) diets were formulated to contain two protein concentrations (35% and 45% crude protein, CP) and 3 levels of taurine supplementation (0, 5 and 10 g/kg) in a 2 × 3 factorial scheme, with four replicates. One hundred postlarvae (initial weight 0.14 ± 0.01 g) were stocked in each of twenty-four 45-L tanks, connected with recirculating marine water system. Shrimps were fed the experimental diets (10% biomass) 3 times a day for 30 days. Dietary protein concentration did not influence growth neither feed utilization of the post-larvae, but a benefic effect of the diet supplementation with taurine on both protein levels tested was evident. Post-larvae fed diets with the highest taurine supplementation (10 g/kg) achieved significant higher final weight, weight gain, specific growth rate and better feed conversion than those fed the other diets.Average survival rate was greater than 92% and it was not affected by experimental diets. Crude protein level of 35% in the diet (22.58 mg CP/kJ ME) is enough to promote adequate growth of L. vannamei post-larvae and shrimp performance ca...
