“…Such growth performance parameters were higher than those described by Lemos et al (2012) for the same fish (7.7 ± 0.2 g) when fed diets containing 26% crude protein; but the feed conversion was better. Moreover, the weight gain was similar to that reported by Pereira-Junior et al (2013), for tambaqui (6.6 ± 0.1 g) fed on diets containing 38.3% crude protein, but apparent feed conversion was also lower. However, such differences are attributed to the initial fish size, which were larger in this study, and also to the different levels of protein used in the diet.…”

Homeopathic products may act in an organism by stimulating the immune system, allowing the restoration of balance and encouraging organic response under stress. This study investigated the performance, blood, morphological and parasitological parameters in Colossoma macropomum (tambaqui) fed diets containing different concentrations of Homeopatila 100 ®. Juvenile tambaqui underwent four treatments with three replicates: 0, 20, 40 and 60 ml Homeopatila 100 ® /kg of extruded feed with 32% crude protein for 60 days. At the end of 60 days the growth performance, blood parameters, gill parasites and hepatic histology in fish fed homeopathic product were evaluated. Treatment with Homeopatila 100 ® did not improve the growth performance of fish. There was no difference in the prevalence and abundance of monogeneans and protozoans in the gills of fish, except in those fed with 60 ml homeopathic product. The plasma glucose levels were higher in fish fed diet containing 40 and 60 ml homeopathic product. The mean corpuscular volume and hematocrit levels in fish fed 20 and 60 ml were higher than in controls. In fish with fed 40 ml increased number of neutrophils and reduced number of lymphocytes was found. However, 60 ml of the product caused increase in the number of monocytes and reduced the number of lymphocytes, eosinophils and PASpositive granular leukocytes. Under conditions in this study, the Homeopatila 100 ® did not improve fish performance or reduce parasitic infections, but showed a relative improvement in blood response of fish fed on 40 ml of this homeopathic complex.

“…O milho pode ser totalmente substituído por farinha de crueira de mandioca, na alimentação de juvenis de tambaqui (Pereira-Júnior et al, 2013), inclusive, este ingrediente contém cerca de 93,7 % de carboidratos e 1,7 % de proteína bruta . Adicionalmente, a inclusão de 25 % da fruta taioba em substituição ao milho na dieta de juvenis de Clarias gariepinus, não apresentou prejuízo à espécie (Zaid e Sogbesan, 2010).…”

Crescimento de tambaqui alimentado com diferentes niveis de farinha de manga e proteína na ração

PALAVRAS CHAVE ADICIONAIS SUMMARYThe study evaluated tambaqui, Colossoma macropomum, performance fed different levels of mango (Mangifera indica) meal in the feed (20, 30, 40 and 50 %) and the reduction of protein levels (38, 33, 28 and 23 %). To this study, 240 fish were used, separated in 12 equal groups, in four treatments and three replications in a randomized system. Initial weight was 5,21; 5,24; 5,19 and 4,99 g respectively. The trial lasted 56 days and fish were periodically weight. Fish were fed daily ad libitum. The following performance parameters were analyzed: specific growth, biomass gain; apparent fed conversion, survival, metabolic profile and digestives enzymes activity. All data show positive polynomial regression for the diet with 50 % mango meal and 23 % protein (R50). Performance parameters had a significant effect with higher results in the groups were mango meal was higher and protein level was lower. Final average weigh was R20: 8,65; R30: 8,81; R40: 8,68 and R50: 11,39 g. From metabolic profile analyzes: glucose, hepatic glycogen, total amino acids and cholesterol it was observed that there are a mobilization from these metabolites in order to keep energy process for tambaqui growth. It was concluded that the best tambaqui performance occured in the diet with 50 % of mango meal inclusion and 23 % of protein. Fish metabolic profile is positively affected by the replacement of protein by mango meal.

“…O crescimento positivo na produção do tambaqui está diretamente relacionado à dieta empregada no cultivo da espécie (BEZERRA et al, 2014), sendo que o preço da ração se eleva de acordo com o teor de proteína nela contido, e isso é agregado no custo da produção piscícola, representando até 80% das despesas (PEREIRA JUNIOR et al, 2013). Porém, o valor nutritivo de uma ração não depende apenas do teor de nutrientes que esta detém, mas também da capacidade do animal em digerir e assimilar os nutrientes contidos no alimento (SMITH, 1971).…”

RESUMO. O presente estudo ocorreu no período de setembro a dezembro de 2014, com a finalidade de avaliar a influência do uso de rações com diferentes concentrações de proteína bruta-PB (28% e 32%), no ganho de peso do tambaqui Colossoma macropomum alimentado com essas dietas distintas. Para tal, foram analisados 500 exemplares de tambaqui com peso médio inicial de 225,33 g ± 11,31 e cultivados até a fase de abate com ≈ 1000 g, estes indivíduos foram divididos e cultivados em tanques separados. Biometrias quinzenais foram realizadas utilizando 10% de cada grupo aleatoriamente, para mensurar as variáveis de peso (g) e comprimento (cm). Ao mesmo tempo, dados relacionados aos parâmetros limnológicos dos tanques foram coletados. O conjunto de informações colhidas foram posteriormente utilizadas para os cálculos estatísticos, empregando o pacote estatístico Statistic 9.0, onde foi considerado α = 0,05 estatisticamente significante em todas as análises. Os resultados mostraram que os teores proteicos de 28 e 32% de proteína bruta na ração não influenciaram significativamente nas variáveis ganho de peso e comprimento do tambaqui entre os diferentes grupos testados. Ainda, a ração com menor teor proteico 28% PB foi a mais adequada para o cultivo da espécie por apresentar um melhor custo benefício na produção.
