“…The differences between the apparent digestibility coefficients of this research and of other studies used for comparison can be attributed to several factors, such as the inclusion level of test ingredient, possible anti-nutritional factors or amino acid imbalance (Mukhopadhyay & Ray, 1997), the methodology used to collect feces (Sullivan & Reigh 1995), the fish line (Degani et al, 1997), the formulation and processing of feeds and ingredients (McGoogan & Reigh 1996), variety (Leterme et al, 1991) and even the soil where the beans are grown (Owsley et al, 1987).…”

-It was determined in this work the coefficients of apparent and true digestibility of protein and amino acids of five feeds (corn, wheat bran, soybean meal, corn gluten meal, fish meal) in Nile tilapia. It was used 252 reverted Thai strain Nile tilapia (Oreochromis niloticus) in growth phase, with weight of 310 ± 9.68 g, distributed in experimental randomized blocks design, with five treatments, six replicates per treatment and seven fish per experimental unit. Each experimental diet contained a single source of protein, composed by the studied ingredients. An additional group of fish was fed protein-free diet for quantification of the endogenous fraction and determination of true digestibility coefficients. Digestibility was estimated by the indirect method by using chromium oxide at the concentration of 0.50% of the diet as a marker, performing fecal collection at every four hour interval by using decantation technique. Digestibilidade aparente e verdadeira de proteína e aminoácidos de alimentos em tilápia-do-nilo RESUMO -Foram determinados nesta pesquisa os coeficientes de digestibilidade aparente e verdadeira da proteína e dos aminoácidos de cinco alimentos (milho, farelo de trigo, farelo de soja, glúten de milho e farinha de peixe) em tilápias-do-nilo.Utilizaram-se 252 tilápias revertidas (Oreochromis niloticus) em fase de crescimento, da linhagem tailandesa, com peso de 310 ± 9,68 g, distribuídas em delineamento de blocos casualizados, composto de cinco tratamentos, seis repetições por tratamento e sete peixes por unidade experimental. Cada dieta experimental continha uma única fonte proteica, composta pelos ingredientes estudados. Um grupo adicional de peixes foi alimentado com dieta isenta de proteína para quantificação da fração endógena e determinação dos coeficientes de digestibilidade verdadeira. A digestibilidade foi estimada pelo método indireto, utilizando-se óxido crômico na concentração de 0,50% da dieta como indicador, efetuando-se a coleta de fezes em intervalos de 4 horas pela técnica de decantação.

RESUMO -O experimento foi conduzido com o objetivo de avaliar os coeficientes de digestibilidade aparente (CDa) da matéria seca (MS), energia bruta (EB) e proteína bruta (PB) do farelo de soja (FS), milho (MO), trigo (TG), farelo de trigo (FT), milheto (MT), triticale (TC), farinha de varredura de mandioca (FM) e óleo de soja (OS) para tilápia do Nilo da linhagem tailandesa. Foram utilizados 100 animais revertidos sexualmente, com peso médio de 37,61 ± 4,98 g distribuídos em dois tanques de alimentação de 500L e coleta de fezes pelo sistema modificado de Guelph em dois aquários (150 L Apparent Digestibility of the Energy and Nutrients of Conventional and Alternatives Foods for Nile Tilapia (Oreochromis niloticus)ABSTRACT -The trial aimed to evaluate the apparent strain digestibility coefficients (CDa) of dry matter (MS), gross energy (EB) and crude protein (PB) of soybean meal (FS), corn (MO), wheat (TG), wheat meal (FT), millet pearl (MT), triticale (TC), cassava meal (FM) and soybean oil (OS) of Nile tilapia fingerlings of Thai. One hundred sexual reverted animals were used, with a mean weight of 37.61 ± 4.98g, distributed in two alimentation 500L mansory tanks and feces collect in modified Guelph system in two 150L aquariums. CDa was determined by an indirect method, with 0.1% chromic oxide (Cr 2 O 3 ) as marker. CDa of MS, PB and EB was 65.49, 89.58 and 71.38 for FS; 73.22, 93.40 and 76.63 for MO; 86.51, 96.30 and 87.07 for TG; 66.79, 91.00 and 68.81 for FT; 77.96, 94.91 and 89.12 for MT; 68.51, 94.78 and 80.55 for TC; 91.11, 97.52 and 91.40% for FM, respectively, and for EB of soybean oil 89.85%, the values of digestible protein (%) and energy (kcal/kg) were 42.19 and 3057.63 for FS; 7.18 and 3037.03 for MO; 11.01 and 3423.66 for TG; 13.44 and 2825.88 FT; 13.88 and 3755.55 MT; 13.74 and 3230.69 for TC; 1.76 and 3280.09; for FM and 8485.28 kcal/kg of energy digestible for OS. The results showed that the protein and energy of these foods are efficiently used by Nile tilapia. To formulate complete diets the digestible protein and energy values must be used.

“…High energy diets concur for a reduced protein and essential nutrients intake (CHOU; SHIAU, 1996;PEZZATO et al, 2001) and an increase on fat deposition in several fish species (MACGOOGAN;REIGH, 1996;MUKHOPADHYAY;RAY, 1997). On the other hand, diets with low energy content increase the use of protein as an energy source, increasing the feed efficiency ratio and the cost of production.…”

The optimal dietary digestible protein to energy ratio is critical for the success of fish farming. Considering that it provides the proper development of the animals, this study was undertaken to evaluate the effects of different dietary digestible protein to energy ratio in diets for goldfish fingerlings. Diets were formulated to contain 28.0, 35.0, 42.0 and 49.0% DP and 3,600 and 3,200 kcal/ kg. The growth parameters evaluated were daily weight gain (DWG), feed intake (FI), feed conversion ratio (FCR), protein efficiency ratio (PER), protein productive value (PPV) and energy retention ratio (ERR) and specific growth rate (SGR). Regardless FI, all the parameters were affected by protein and energy levels and interaction between both factors was observed. The second-order polynomial equation best fitted to the DWG, SGR, FCR, PER and ERR with estimated requirement values of 38.81, 38.85, 41.05, 41.80 and 39.39% DP, respectively, at the 3,200 kcal/kg. A second-order polynomial model was significant only for the ERR data at the 3,600 kcal/kg with an estimated requirement value of 36.45% DP. Generally, fish fed diets containing 3,200 kcal/kg had better growth performance than fish fed 3,600 kcal/kg (P<0.01), indicating a higher feed efficiency. A 3,200 kcal/kg diet seems to be the proper DE level for meeting goldfish requirement for highest weight gain. Based on this experimental condition, we recommend the use of DP levels between 38.0-40.0% in diets for goldfish with 3,200 kcal/kg or a dietary protein to energy ratio between 119-125 mg/ kcal DE.Index terms: Energy requirement, feed intake, growth protein requirement, ornamental fish. RESUMOA ótima relação energia/proteína é importante para o sucesso da piscicultura. Considerando que a mesma fornece o adequado desenvolvimento dos animais, este estudo foi realizado para avaliar a relação energia/proteína digestível ótima para alevinos de kinguio. Dietas foram formuladas para conter 28,0; 35,0; 42,0 e 49,0% PD e 3600 e 3200 kcal/kg. Foram avaliados: ganho de peso diário (GPD), consumo de ração aparente (CRA), conversão alimentar aparente (CAA), taxa de eficiência protéica (TEP), valor produtivo protéico (VPP), taxa de retenção de energia (TRE) e taxa de crescimento especifico (TCE). Com exceção do CRA, todos os parâmetros foram afetados pelos níveis de proteína e energia e interação entre os dois fatores foram observados. O modelo que melhor se ajustou aos parâmetros GPD, TCE, CAA, TEP e TRE foi o polinomial de segunda ordem com valores de exigência de 38,81; 38,85; 41,05; 41,80 e 39,39% DP, respectivamente, para o nível de 3200 kcal ED/kg. O modelo polinomial de segunda ordem foi significativo apenas para os dados de TRE no nível de 3600 kcal ED/kg, com valor de exigência 36,45% PD. Os peixes alimentados com dietas contendo 3200 kcal/kg apresentaram melhor desempenho de crescimento do que os alimentados com 3600 kcal/kg (P<0,01), indicando uma maior eficiência alimentar. 3200 kcal/kg ED parece ser o nível adequado encontrado para kinguio para maior ganho d...
