An experimental study was done during 7 weeks to preliminarily evaluate the effect of “pionilla” (Lasianthaea podocephala) tuber powder, as a feed additive on the production parameters, food consumption, and nutritional condition of the white shrimp (Litopenaeus vannamei) intensively farmed under laboratory conditions. The powder was included at different levels (0 [C], 0.2 [T1] and 1 g·kg-1 [T2]) in a commercial shrimp feed. Pionilla powder exhibited a free aminoacid profile in which arginine (8.59 mg g-1) and glutamine (3.36 mg g-1) were the most abundant. Feed consumption was not influenced by any treatment; however, the survival and the overall production responses were greater in both treatments using pionilla (T1 and T2) compared to C. No significant differences were detected in muscle concentrations of lactate and glucose, although higher protein and lower cholesterol concentrations were observed in shrimp reared in C treatment. The lower cholesterol concentration of C shrimp could be associated to a poor nutritional status. In conclusion, the inclusion of pionilla did not improve the feed consumption, but apparently had a positive effect on survival, production response and nutritional status of shrimp. These responses could be associated to a hypothetic effect of pionilla at a nutritional-molecular level, or to a possible antimicrobial effect of the pionilla tuber; however, further specific studies are needed.
