“…In the sea bream (F101), C 24 bile acids were conjugated with cysteinolic acid, a taurine congener that is thought to be of dietary origin, specifi cally in ingested algae ( 62,63 ). In some species of angel fi sh (F84-F93) and the bulbous dreamer (F39), bile acids were conjugated with N -methyltaurine.…”

Influence of soya saponin, soya lectin, and cholyltaurine supplemented to a casein-based semipurified diet on intestinal morphology and biliary bile status in fingerling rainbow trout Oncorhynchus mykiss

To investigate the cause of the changes in intestinal morphology and biliary bile status of rainbow trout Oncorhynchus mykiss fed defatted soybean meal (SBM)-based diets, casein-based semipurified diets supplemented with soya saponin, soya lectin, and cholyltaurine were fed to rainbow trout for 6 weeks. An unsupplemented control diet and a SBM-based diet were also tested as references. Poor development of microvilli and pinocytotic vacuoles, and accumulation of large vacuoles in the epithelial cells were observed in the distal intestine of fish fed diets containing saponin but not cholyltaurine. Hyperplastic connective tissue in the mucosal folds of the distal intestine was observed in fish fed a diet containing both saponin and lectin but not cholyltaurine. However, intestinal histological features in fish fed diet supplemented with cholyltaurine and lectin and/or saponin were similar to those in the control diet group. Liver morphology and biliary bile status were not affected by saponin and lectin. These results suggest that the abnormal features of the distal intestine of rainbow trout fed SBM-based diets are caused by the combination of soya saponin and soya lectin, and that supplemental cholyltaurine plays certain roles in normalizing the intestinal abnormalities caused by the saponin and lectin.

“…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).…”

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...
