Abstract: Se evaluó el efecto de la zeolita como aditivo en el alimento de postlarvas y juveniles de camarón blanco Litopenaeus schmitti (0.8 ± 0.02 mg y 2.35 ± 0.1 g de peso inicial promedio respectivamente). Los bioensayos tuvieron una duración entre 30–50 días y se ensayaron alimentos balanceados elaborados a base de materias primas convencionales con diferentes niveles de inclusión de zeolita. Los niveles de zeolita ensayados no afectaron la supervivencia de las postlarvas y juveniles. Las postlarvas que consumieron la dieta con 1% de zeolita alcanzaron los mayores crecimientos (p<0.05). La inclusión de este ingrediente mejoró significativamente el factor de conversión del alimento en ambos grupos experimentales. La relación entre el nivel de inclusión de zeolita (Z) en la dieta de las postlarvas con el peso final (PF) se describió a través de la ecuación PF = 25.587 + 4.9327 Z – 2.7455 Z2 (R2=0.69), la que sugiere un nivel óptimo de inclusión de zeolita de 0.9%.
Use of zeolite in White Shrimp Litopenaeus schmitti feeding The effect of zeolite as feed additive in postlarvae and juvenile Litopenaeus schmitti was evaluated (0.8 ± 0.02 mg and 2.35 ± 0.1 g initial average weight respectively). The bioassays had duration of 30–50 days. Practical diets that were elaborated with conventional raw materials and including different zeolite levels were attempted. Survival in post larvae and juveniles was not affected by zeolite levels tested. Postlarvae fed with diet containing 1% of zeolite reached the highest growth (p<0.05). Feed conversion ratio was improvement when zeolite was included in diets in both experimental groups. The relation of zeolite inclusion level (Z) in post larvae diet with final weight (FW) was described by the following quadratic equation: FW = 25.587 + 4.9327 Z – 2.7455 Z2 (R2=0.69), which suggested that optimum zeolite inclusion level in practical diets was 0.9%.
