A preliminary evaluation of the San Pedro daisy (Lasianthaea podocephala) tuber powder, as a feed additive on the intensive culture of shrimp (Litopenaeus vannamei) under laboratory conditions
An experimental study was carried out during seven weeks to preliminarily evaluate the effect of the dietary inclusion of powder from the tuber Lasianthaeapodocephala, commonly known as the San Pedro daisy or pionilla, as a feed additive on the production parameters, food consumption, and nutritiona...
