“…An opposite result of the present experiment, is related by Veiverberg et al (2010), studying a protein diet with grass carp (Ctenopharyngodon idella), where an increase in body fat deposition occurred, following the increase of dietary protein level. This difference between the two species can be attributed to the fact that grass carp is not much efficient in the use of car bohydrates (Takeuchi et al, 1994).…”

The objective of this study was to determine crude protein requirement for Hypostomus commersoni fingerlings. Seventy two fingerlings of armoured catfish were used with average weight of 2.44 ± 0.14g, distributed in nine tanks, totalizing eight fish per experimental unit. In a completely randomized design, with three treatments and three replications. Three experimental diets were prepared with protein levels of 25, 30 and 40% and isocaloric (3.500 kcal. kg-1). The fish were fed daily with at the rate of 5% of body weight for 10 weeks. Evaluated variables were final average weight, weight gain, specific growth rate (SGR), survival and body composition. Dietary levels of protein did not affect weight gain, specific growth rate and survival. Crude protein higher levels in the diet increased the deposition of protein and reduced body fat (p≤0.05). Levels of 25% crude protein in the diet of armored catfish are suffi cient for good growth performance, however, raise levels may be beneficial, increasing protein deposition in the carcass and reducing body fat.

“…In trout meat they reduced the fat and energy and increased protein, and ash contents were elevated with higher carbohydrate (Veiverberg et al, 2010). Fabregat et al (2011) evaluated substitution of fish meal by soybean meal in the diet and verified reduction in the crude protein contents of the carcass of Prochilodus lineatus juveniles.…”

The effect of mango waste meal in the protein:carbohydrate ratio on performance and body composition of pacamã fish (Lophiosilurus alexandri) [ ABSTRACTAvaliou-se a inclusão do farelo residual de manga sem casca como fonte de carboidrato na relação proteína:carboidrato (PB:CHO) sobre o desempenho e a composição química da carcaça em juvenis de pacamãs. Foram utilizados 150 peixes (11,31±0,96g) estocados em 16 caixas de 500L, alimentados três vezes ao dia (10% peso vivo), em um sistema de recirculação de água com biofiltro. Os tratamentos consistiram em quatro dietas experimentais com níveis decrescentes da relação entre proteína bruta e carboidrato (1,40; 0,94; 0,56 e 0,29), com quatro repetições cada tratamento. Ao final de 60 dias, foram avaliados o desempenho zootécnico (ganho de peso médio final, taxa de crescimento específico, consumo total de ração aparente, conversão alimentar aparente, rendimento de carcaça, sobrevivência) e a composição físico-química da carcaça. As relações de proteína:carboidrato afetaram todas as variáveis de desempenho (P<0,05), com exceção da sobrevivência (P>0,05). Os valores da composição química da carcaça foram alterados, com exceção da matéria mineral, do pH e da umidade. A farinha de manga pode ser utilizada na proporção de até 15% na ração de pacamã, estabelecendo uma relação 1,40 PB:CHO, sem prejudicar o desempenho zootécnico e a composição química da carcaça. (11.31±0.96g) were stocked in sixteen 500 L tanks, fed three times daily (10% of live weight), in a system with water recirculation with biofilter. The treatments consisted of four experimental diets with decreasing levels of the ratio between crude protein and carbohydrate (1.40, 0.94, 0.56 and 0.29) Palavras-chave: nutrição, inclusão, carcaça RESUMO We evaluated the inclusion of peeled-mango waste meal as a source of carbohydrate in the protein:carbohydrate ratio (CP:CH) on performance and chemical composition of pacamã (Lophiosilurus alexandri) juveniles.

“…According to Veiverberg et al (2010), variable results on body composition of fishes are obtained as the effect of inclusion of plant ingredients, with the main response observed in the body fat and/or fillet contents. In addition to the energy/protein, a diet with an imbalanced amino acid profile can result in greater fat deposition (Botaro et al, 2007), which may explain the variation in this experiment of fat values in the carcass.…”

-This study was conducted to evaluate performance and body composition of tilapia (Oreochromis niloticus) fed diets containing byproducts aerial parts of cassava meal (Manihot esculenta), mesquite pod meal (Prosopis juliflora), cocoa meal (Theobroma cacao) and palm kernel cake (Elaeis guineensis) and to analyze the economic viability of the feed. A total of 1,350 juvenile males (100 g) were distributed in 15 cages (1 m 3 ) in completely randomized design with five treatments (basal diet and four test diets) and three replicates. The following aspects were evaluated: final weight, total feed intake, total weight gain, feed conversion, specific growth rate, protein efficiency ratio and survival rate, dry matter, crude protein, fat and ash body, the average cost of feed per kilogram of weight gain and economic efficiency rate.No differences were observed for total consumption of food or survival rate. For other variables, the inclusion of cocoa and cassava meal impaired fish performance. No differences were observed for dry matter, crude protein and body ash. The lower body fat accumulation was recorded for the tilapia fed palm kernel cake. The best economic indicators were found to diets containing palm kernel cake. The byproducts evaluated can be used up to 150 g/kg in feed formulation, providing good performance and economic rate for Nile tilapia.
