| Abstract | Las algas marinas se han evaluado como aditivos alimentarios para organismos acuaticos con resultados positivos en las variables productivas y en la resistencia a enfermedades. En la presente investigacion se evaluo un extracto liquido de Macrocystis pyrifera (Kelproidan MR ) al 4% de inclusion (K4%) en alimento balanceado (33.6% proteina y 7.3% lipidos) para juveniles de Litopenaeus vannamei. Se realizo un bioensayo de crecimiento durante 45 dias en condiciones controladas. Comparado con el tratamiento testigo, los resultados indican que la inclusion de Kelproidan MR no afecto la supervivencia, crecimiento, consumo de alimento y la respuesta alimentaria de los camarones, el tratamiento K4% mejoro la conversion alimenticia y la eficiencia proteica ( P <0.05). Ademas, incremento el contenido de proteina y disminuyo el contenido de lipidos del musculo en los camarones ( P <0.05). Las conclusiones obtenidas en el experimento indican que el producto comercial Kelproidan MR podria utilizarse como aditivo alimentario en alimentos para juveniles de camaron patiblanco del Pacifico. Seaweeds have been evaluated as feed ingredients or additives for aquatic organisms with positive results on growth performance and disease resistance. To evaluate the response of growth and feed utilization using a seaweed liquid extract (Kelproidan MR ), obtained from Macrocystis pyrifera as a feed additive 4% inclusion (K4%) in balanced feed (33.6% protein and 7.3% lipids) for juvenile Litopenaeus vannamei , a 45 days growth bioassay, under controlled conditions was conducted. Compared to the control treatment, the results indicate that the inclusion of Kelproidan MR did not affect the zootechnical parameters of survival, growth, feed intake nor the feeding response of shrimp. In terms of feed utilization, K4% treatment significantly improved feed conversion rate, and protein efficiency (P<0.05). It was also revealed that Kelproidan MR allowed two different responses in proximate composition of shrimp muscle, first increased protein content and otherwise decreased lipid content (P<0.05). In conclusion, Kelproidan MR could be used as a feed additive for juvenile L. vannamei . |
