Apparent digestibility of ingredients in diets for Salminus brasiliensis
The objective of this work was to determine the nutritional value of different protein sources for "dourado" (Salminus brasiliensis). Thirty juveniles per group (33.51±1.4 g) were hand fed on a reference diet (70%) added of tested ingredients (30%) and chromium oxide III (0.1%)....

Summary: | The objective of this work was to determine the nutritional value of different protein sources for "dourado" (Salminus brasiliensis). Thirty juveniles per group (33.51±1.4 g) were hand fed on a reference diet (70%) added of tested ingredients (30%) and chromium oxide III (0.1%). Apparent digestibility coefficients of the gross energy (ADC GE), crude protein (ADC CP) and amino acids of the tested ingredients were evaluated. Corn gluten meal yielded the best results for ADC GE and ADC CP (95.7 and 96.9%, respectively) amongst plant ingredients. Spray-dried blood meal yielded the best values of ADC GE and ADC CP amongst animal ingredients (94.1 and 96.3%, respectively). Wheat bran yielded poorest ADCs coefficients (77 for ADC GE and 88.2% for ADC CP).
O objetivo deste trabalho foi determinar o valor nutricional de diferentes fontes protéicas para o Dourado (Salminus brasiliensis). Trinta juvenis por grupo (33,51±1,4 g) foram alimentados ad libitum com ração referência (70%) mais ingredientes-teste (30%) e marcador de óxido de cromo III (0,1%). Foram determinados os coeficientes de digestibilidade aparente da energia bruta (CDA EB), proteína bruta (CDA PB) e aminoácidos. Entre os ingredientes de origem vegetal, a glutenose apresentou os melhores resultados para CDA EB e CDA PB (95,7 e 96,9%, respectivamente). A farinha de sangue se destacou entre os ingredientes de origem animal (94,1 e 96,3%, respectivamente). O farelo de trigo apresentou menor digestibilidade entre todos, 77% para CDA EB e 88,2% para CDA PB. |
