The effect of dietary supplementation of medium-chain fatty acids products on gut and hepatopancreas health, and disease resistance in white shrimp (Litopenaeus vannamei)

This study was to investigate the effect of medium-chain fatty acids products Aromabiotic® Shrimp (ABS) on growth, gut and hepatopancreas health, gut microbiota and resistance to bacterial infection and adverse environment of white shrimp.

After 5-week feeding, there was no significant difference in weight gain, feed conversion ratio and survival among groups. However, ABS diets significantly improved the survival of the white shrimp after Vibrio parahaemolyticus challenge (ABS5, P
