“…The digestibility coefficient of threonine for soybean meal, corn gluten meal, corn flour and wheat bran values found in this study were similar to those obtained by Ribeiro et al (2011Ribeiro et al ( , 2012 for tilapia, with the ADC of threonine varying between 73.0% to 90.3%. Although silver mojarra is an omnivorous species, the digestibility coefficient of threonine for fish meal was similar to that reported by Davies et al (2009) for carnivorous marine species such as turbot, bream and European seabass, with the ADC exceeding 88%.…”

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...

“…In addition, the identification of the nutritional value through digestibility studies will reveal the efficiency and utilization capacity of these feedstuffs by animals (Adéyèmi et al, 2020). In fish, this is commonly determined by quantifying the apparent digestibility coefficient (ADC) (Ribeiro et al, 2012;Solomon et al, 2017). Details on different methodologies used in digestibility studies have been extensively reported in literature.…”

Ulva lactuca is an algae that is a source of protein for fish and can increase resistance to disease. The purpose of this study was to determine the effect of ethanolic extracts Ulva lactuca on growth and survival rate of milkfish (Chanos chanos). This research was conducted at Brackish Water Aquaculture Development Center, Ujung Batee, Aceh, Indonesia on April-March 2019. Data were analyzed using a completely randomized design with 6 treatments and 4 replication, namely A (0 ppm), B (100 ppm), C (200 ppm), D (300 ppm), E (400 ppm), F (500 ppm). The parameters measured were absolute weight growth, absolute length growth, specific growth rate, survival rate and water quality. The ANOVA test results showed that the Ulva lactuca extract had a significant effect (P<0.05) on absolute weight growth, absolute length growth and specific growth rate but had no effect (P>0.05) on the survival rate of milkfish (Chanos chanos). The concentration of 500 ppm extract Ulva lactuca (treatment F) produced the highest on absolute weight growth (1.52 g), absolute length growth (1.96 mm), specific growth rate (0.30 %/day), and survival rate (96%).
