Effect of microencapsulated phenolic compound extracts of Maclura tinctoria (L.) Steud on growth performance and humoral immunity markers of white leg shrimp (Litopenaeus vannamei, Boone, 1931) juveniles

Aim of study: The effect microencapsulated phenolic compound extracts Maclura tinctoria (MTBE) on growth performance and humoral immunity markers the white leg shrimp Litopenaeus vannamei juveniles (0.5 ± 0.2 g initial weight) was studied.Area M. collected from Hampolol, Campeche, Arroyo del Agua, Culiacan, Sinaloa, Mexico.Material methods: Three MTBE inclusions (0.5, 1, 2.5 MTBE/kg, Purina®) were compared with a control commercial feed (Purina®) during 30 days. Nine acids, nine flavonols, four dihydro-flavonoids, flavones, seven unidentified compounds determined fin using Perkin Elmer® HPLC chromatograph diode array-detection.Main results: mean concentrations total compounds, flavonoid condensed tannins 198.05 5.59 mg gallic acid equivalent (GAE) g-1 dw, 78.57 1.80 quercetin g-1, 28.32 0.33 epicatechin respectively. ferric reducing antioxidant power capacity, respectively, averaged GAE mL-1 10.9 ascorbic mL-1. Survival, weight gain, specific rate L. similar among experimental diets. dietary inclusion at 0.5 g/kg food showed significant higher (p < 0.05) plasma hemocyte lysate protein (1.35 0.055 µg mL-1), prophenoloxidase (0.47 0.15, Abs. 492 nm), superoxide anion (O2.-) activity (0.21 0.07, 630 nm).Research highlights: supplementation could be considered as potential alternative additive for diet in juvenile production, since it improved response post larval life stages, when cultivated are more susceptible to infected by pathogens.
