          Abstract

          Avaliou-se nesta pesquisa o efeito de diferentes fontes de carboidratos no desempenho de alevinos de tilápia. Foram testadas quatro dietas isoproteicas com diferentes concentrações de farinha de manga 0; 33, 66, e 100% em substituição ao milho. O período de alimentação foi de 45 dias, e a taxa de arraçoamento foi de 8% da biomassa. Foram utilizados 360 alevinos de tilápia-do-nilo, com peso médio inicial de 2,08±0,13g, distribuídos em 12 caixas de 500L, em um sistema de recirculação de água com biofiltro. Foram avaliados índices de desempenho, consumo de ração, rendimento de carcaça e sobrevivência. Os resultados obtidos demonstraram que o ganho de peso individual, o ganho médio diário, a taxa de crescimento específico, o consumo de ração aparente, a conversão alimentar aparente e a sobrevivência não foram afetados pelas fontes de carboidratos testadas. O rendimento de carcaça foi influenciado pela farinha de manga na ração. Concluiu-se que o milho na dieta pode ser substituído 100% pela farinha de manga para a tilápia, sem prejudicar o desempenho.

          The aim of this study was to evaluate the effect of different carbohydrates on the performance of Tilapia fingerlings. Four isoproteic diets with different concentrations of mango meal (0, 33, 66 and 100%) were tested to replace the cornmeal. The feeding period was 45 days and the feeding rate was 8% of the biomass. Three hundred and sixty nile tilapia fingerlings with initial average weight of 2.08±0.13g, distributed into 12 500L experimental units, in a water recirculating system with biofilter were used. Performance indicators such as feed intake, carcass yield and survival rate were also evaluated. The results showed that the individual weight gain, average daily gain, specific growth rate, apparent feed intake, apparent feed conversion and survival were not affected by the two sources of carbohydrates tested. The carcass yield was influenced by mango meal in the diet. It was concluded that the replacement of maize in the diet can be done with 100% mango meal for Tilapia.

            Apparent inability of channel catfish to utilize dietary mono- and disaccharides as energy sources.

            Purified diets containing equivalent amounts of glucose, maltose, fructose, sucrose, corn starch and dextrin were fed to fingerling channel catfish (Icatalurus punctatus) to compare the growth responses to these various carbohydrates. The best growth response was achieved with dextrin and the next best with corn starch. Fish grew at the same rate when glucose, maltose or sucrose was the only dietary carbohydrate source. Dietary fructose resulted in the lowest growth rate. Feed efficiency and percent retained energy values followed the same pattern as growth rates. These data suggest that the catfish is apparently unable to utilize dietary mono- and disaccharides as energy sources. Oral carbohydrate tolerance tests using glucose, maltose, fructose, sucrose and dextrin were conducted with larger channel catfish. Oral glucose and maltose resulted in a persistent hyperglycemia indicative of a diabetic-like status. Fructose appeared to be poorly absorbed from the intestinal tract and did not appear to be converted to glucose. Oral administration of sucrose was followed by a gradual increase in plasma glucose, with no detectable fructose being absorbed until the 6-h period. Oral dextrin resulted in less than a two-fold increase in plasma glucose, which remained constant from 2 to 4 h after administration and then declined. These observations are consistent with the hypothesis that certain fishes, including the channel catfish, resemble diabetic animals by having insufficient insulin for maximum carbohydrate utilization.
