Filamentous microalga Klebsormidium sp.has huge potential to become a natural and healthy additive in aquatic feed since it contains various bioactive nutrients, such as linoleic acid (LA), carotenoids, and chlorophylls.Therefore, an eight-week feeding experiment was performed to evaluate the effects of dietary Klebsormidium sp.on the growth performance, antioxidant and anti-inflammatory status, metabolism, and mid-intestine morphology of virginia mill works tobacco road acacia Litopenaeus vannamei.
Two isonitrogenous and isolipid diets supplemented with and without 5% Klebsormidium sp.were prepared.Results showed that L.vannamei fed with Klebsormidium sp.
had better growth performance and feed utilization by optimizing mid-intestine morphology and improving the carbohydrate metabolism.In addition, Klebsormidium sp.also enhanced the antioxidant capacity of L.vannamei by downregulating antioxidant parameters (hepatopancreas T-SOD, hepatopancreas GSH-PX, hemolymph T-SOD, hemolymph MDA) and RNA expression levels of antioxidant genes (gsh-px and cat).
Furthermore, the supplementations of dietary Klebsormidium sp.significantly improved hepatopancreas health by downregulating RNA expression levels of pro-inflammatory related genes (relish and rho).Therefore, a dose of 5% Klebsormidium sp.is recommended for the daily diet iphone 14 price chicago of L.
vannamei to improve the growth performance, antioxidant and anti-inflammatory status, metabolism, and mid-intestine morphology of shrimp.
