Knowledge on the nutritional value of feed ingredient is an important step in the formulation of diets in order to maximize animal productivity. Thus a study was conducted to determine the apparent digestibility coefficients (ADC) of dry matter (ADCDM), crude protein (ADCCP), gross energy (ADCGE) and amino acids (ADCAA) of conventional feed ingredients for juvenile silver mojarra (13.0 ± 3.23 g). The study was conducted in the laboratory for nutrition and feeding of fish (AQUANUT), using 80 silver mojarra collected in nature, which were kept in digestibility aquaria for a period of 21 days. The following ingredients were evaluated: fish meal, soybean meal, corn meal, corn gluten meal, rice bran, wheat bran and starch, which substituted 30% of a reference pelletized diet with 325.00 g kg crude protein and 3,692 Kcal kg -1 gross energy. Additionally 1.0 g kg -1 chrome oxide was added to each diet as a marker. The excreta were obtained using three repetitions for each tested ingredient, which were dried for further analyses. The soybean meal showed the best ADCDM value (67.45%), followed by the other ingredients. There was no significant difference between the soybean meal (95.16%), fish meal (92.97%) and the corn meal (91.90%) for the best ADCCP coefficients. The ADCGE for soybean meal and maize meal were 65.23% and 60.31%, respectively, followed by fish meal (51.85%). The results demonstrate that silver mojarra can digest animal protein as well as that of vegetal origin. Silver mojarra can also efficiently digest and absorb some of the main amino acids of fish, such as lysine, methionine and threonine, from the same studied ingredients. Key words: Acará-peba.

Foi realizado um estudo para determinar os coeficientes de digestibilidade aparente (CDA) da matéria seca (CDAMS), da proteína bruta (CDAPB), da energia bruta (CDAEB) e dos aminoácidos (CDAAA) de ingredientes convencionais para juvenis de carapeba (13 ± 3,23 g). O estudo foi realizado no Laboratório de Nutrição e Alimentação de Peixes (AQUANUT), utilizando 80 exemplares de carapeba, coletados na natureza, que foram mantidos em aquários de digestibilidade no período de 21 dias. Foram avaliados os seguintes ingredientes: farinha de peixe, farelo de soja, fubá de milho, farelo de glúten de milho, farelo de arroz, farelo de trigo e amido, que substituíram 30% de uma dieta referência peletizada com 325,00 g kg -1 de proteína bruta e 3,692 Kcal kg -1 de energia bruta, utilizando 1,0 g kg -1 óxido de cromo como marcador. As excretas foram obtidas utilizando três repetições para cada ingrediente testado, e após a secagem foram realizadas as análises laboratoriais. O farelo de soja apresentou o melhor resultado para o CDAMS (67,45%) seguido pelos demais ingredientes. Para o CDAPB não houve diferença significativa entre o farelo de soja (95,16%), a farinha de peixe (92,97%) e o fub...

“…Essential and nonessential amino acids ADC were similar (P>0.05) for the cultivars orelha de onça, IPA 20 and comum, with exception for phenylalanine and tyrosine (Table 5). Among the essential amino acids, arginine presented higher ADC, corroborating the results obtained for Nile tilapia by Santos et al (2010), who studied forage radish bran; Freire, Barros and Pezzato (2005) using low tannin sorghum and Ribeiro et al (2011) for soybean bran, corn gluten and fishmeal. Cultivars orelha de onça, miúda, IPA 20 and comum presented higher (P<0.05) arginine ADC in relation to the cultivar gigante.…”

The objective was to evaluate the apparent digestibility coefficients of nutrients and energy of five cultivars of forage palm (orelha de onça, miúda, gigante, IPA 20 and comum) for growing Nile tilapia (110.02±16.17 g). The study design was completely randomized with five treatments, three replicates of eight fish per experimental unit. The diets were composed of 300 g/kg of each cultivar of the palm and 700 g/kg of the basal diet. Masculinized fish were distributed in circular feed tanks (150 L) and kept in closed circulation of water and constant aeration. The digestibility was estimated by indirect method, using 1.0 g/kg chromic oxide as an indicator of the diet and the feces was collected the day after the last feed in digestibility aquariums. The cultivars comum and onça presented the best values for dry matter digestibility (53.5%). The lowest value for crude protein digestibility was obtained to cultivar gigante (60%) and all cultivars tested showed gross energy digestibility below 50%. Nile tilapia has limitation on the digestibility of dry matter, gross energy, crude protein and amino acids of the cultivars of forage palm IPA 20, miúda, gigante, comum and orelha de onça.

As tilápias, masculinizadas, foram distribuídas em tanques circulares de alimentação (150 L), mantidos em circulação fechada de água e aeração constante. Foi montado um delineamento inteiramente casualizado, composto por cinco tratamentos, três repetições e oito peixes por unidade experimental. As rações teste foram compostas de 30% de cada cultivar da palma e 70% da ração referência. A digestibilidade foi estimada pelo método indireto, utilizando-se óxido crômico a 0,1% da ração como indicador, efetuando-se a coleta de fezes no dia posterior a última alimentação em aquários de digestibilidade. A cultivares orelha de onça e comum apresentaram os melhores valores para a digestibilidade matéria seca (53,5%). O menor valor para digestibilidade da proteína bruta foi obtido para cultivar gigante (60%) e todas as cultivares testadas apresentaram coeficiente de digestibilidade energia bruta inferior a 50%. A tilápia-do-nilo apresenta limitação quanto à digestibilidade da matéria seca, energia bruta, proteína bruta e aminoácidos das cultivares IPA 20, miúda, gigante, comum e orelha de onça.

The high composition of import raw material of fish diet in Indonesia causes feed price expensively and should be replaced using local materials such as green macro algae. It is, therefore, this study aimed to evaluate effect of diet containing the Caulerpa lentillifera, as feed ingredient in the diet of Nile tilapia Oreochromis niloticus. This study consisted of two experiments which were C. lentillifera digestibility test for raw material feed for tilapia and growth performance test of tilapia. C. lentillifera digestibility test was done by using Cr 2 O 3 as indicators and analysis of faecal tilapia. The second experiment is growth performance test using a completely randomised design with four diets were formulated at variuos rates of C. lentillifera meal of 0 (control), 10, 20, and 30%. A number of 240 tilapia fingerlings of 3.41±0.10 g in mean weight were randomly stocked in 12 aquaria and fed on diet test for growth performanced of rearing period. C. lentillifera digestiility test result showed a good value as a raw material feed tilapia, the digestibility of C. lentiliifera and protein digestibility amounted to 68.81% and 86.31%. Growth performance parameters showed the use of 10% and 20% is not significantly different from the control (P>0.05), to the final body weight, protein efficiency ratio, protein retention, specific growth rate, and feed efficiency. But, the diet test at 30% performed the lowest growth performance and feed utilization as well of tilapia fingerlings. This study, therefore, concludes that C. lentillifera meal could be used up to 20% in the tilapia diet.Keywords: Caulerpa lentillifera, Nile tilapia, feed utilization, growth performance ABSTRAK Tingginya jumlah bahan baku impor dalam pakan ikan di Indonesia menyebabkan harga pakan yang tinggi dan harus diganti menggunakan bahan alternatif lokal seperti makro alga. Penelitian ini bertujuan untuk mengkaji pengunaan dari pakan yang mengandung Caulerpa lentillifera sebagai bahan baku pakan ikan nila Oreochromis niloticus. Tahapan penelitian terdiri atas uji kecernaan C. lentillifera sebagai bahan baku dan uji kinerja pertumbuhan ikan nila.
