Evaluation of different levels of dietary protein and lipids on the growth, feed efficiency, and biometric and hematological indexes of juvenile white snooks, Centropomus viridis

Evaluation of different levels of dietary protein and lipids on the growth, feed efficiency, and biometric and hematological indexes of juvenile white snooks, Centropomus viridis

An experiment was conducted to evaluate the effect of various levels of protein and dietary lipids on white snook (Centropomus viridis) performance. A 4 × 2 factorial design was used with 4 protein levels (40%, 46%, 52%, and 58%) and 2 lipid levels (10% and 13%), with 3 replicates per treatment. Fis...

description An experiment was conducted to evaluate the effect of various levels of protein and dietary lipids on white snook (Centropomus viridis) performance. A 4 × 2 factorial design was used with 4 protein levels (40%, 46%, 52%, and 58%) and 2 lipid levels (10% and 13%), with 3 replicates per treatment. Fish with an initial weight of 14.80 ± 0.80 g were fed to apparent satiety 3 times a day for 6 weeks. Juvenile growth showed no significant differences among treatments. Feed efficiency was only affected by the protein level in the diet, and the best feed efficiency ratio was obtained with the 52% protein diets; the protein efficiency ratio was significantly lower with the 58% protein diets. The hepatosomatic index decreased with increasing protein content, and the peritoneal fat index increased with dietary lipid level. The condition factor was not affected by the dietary protein or lipid level. Hematocrit and total plasma protein were significantly higher at 40% protein; blood glucose and triglycerides were affected by both nutrients. It is concluded that juvenile C. viridis can be fed diets containing 40% protein and 10% lipids and a protein/energy ratio of 20.69 mg·kJ–1, under the experimental conditions of this study.

Se llevó a cabo un experimento para evaluar el efecto de varios niveles de proteína y lípidos dietéticos en el rendimiento de juveniles de robalo blanco (Centropomus viridis). Se realizó un diseño factorial 4 × 2 con 4 niveles de proteína (40%, 46%, 52% y 58%) y 2 niveles de lípidos (10% y 13%), con 3 replicados por tratamiento. Los peces con un peso inicial de 14.80 ± 0.80 g se alimentaron a saciedad aparente 3 veces al día durante 6 semanas. El crecimiento de los juveniles no presentó diferencias significativas entre los tratamientos. La eficiencia alimenticia solo fue afectada por el nivel de proteína en la dieta, y la mejor tasa de eficiencia alimenticia se obtuvo con las dietas con 52% de proteína; el índice de eficiencia proteica fue significativamente menor con las dietas con 58% de proteína. El índice hepatosomático disminuyó al aumentar el contenido de proteína, y el índice de grasa peritoneal aumentó con el nivel de lípidos en la dieta. El factor de condición no fue afectado por el nivel de proteína o lípidos dietéticos. El hematocrito y la proteína total del plasma fueron significativamente mayores con las dietas con 40% de proteína; la glucosa y los triglicéridos en la sangre fueron afectados por ambos nutrientes. Se concluye que los juveniles de C. viridis pueden ser alimentados con dietas que contengan 40% de proteína y 10% de lípidos y una relación proteína/energía de 20.69 mg·kJ–1, bajo las condiciones experimentales de este estudio.
