Resumen

CAMPA-CORDOVA, Angel I.; YENNI-MORALES, Cristóbal; GUZMAN-MURILLO, María A.  y  AGUIRRE-GUZMAN, Gabriel. Productive response and circulating haemocytes in juvenile shrimp Litopenaeus vannamei, fed with probiotic mixtures. Rev. biol. mar. oceanogr. [online]. 2020, vol.55, n.1, pp.73-78.  Epub 01-Ago-2020. ISSN 0718-1957.  http://dx.doi.org/10.22370/rbmo.2020.55.1.2394.

Shrimp diets with mixtures of probiotics (bacilli or yeasts) were evaluated on the production response and immunological effect on juvenile shrimp (Litopenaeus vannamei). The results showed a significant effect in growth, food consumption and feed conversion rate when probiotic diet was used. In addition, experimental diets with yeast mixture [C. insectorum (DH5), D. hansenii (DH6, and L1)] had a significantly higher amount of circulating haemocytes than those with bacilli [B. tequilensis (YC5-2), B. endophyticus (YC3-b) and B. endophyticus (C2-2)]. Shrimp fed both experimental diets (3x107 CFU mL-1) had a significantly higher growth and immune parameters when compared with the commercial diet. Both elements can contribute to the sustainable development and health of shrimp farming.
