Research—Salts Dramatically Increase Shrimp Growth Rates

 

From Abstract: In this study, researchers determined the effect of supplementing shrimp diets (Penaeus vannamei) with sodium salts (formate, acetate, lactate, propionate, butyrate, fumarate, succinate and citrate).  ...In a growth trial, the highest final weights were in shrimp fed diets supplemented with fumarate, succinate, butyrate and propionate, increasing 53%, 46%, 38% and 29%, respectively, compared to the control.  Shrimp that were fed diets with fumarate digested more feed and had a feed conversion ratio 23% higher than the control shrimp.  Shrimp survival did not differ among treatments.  The researchers concluded that organic salts in the diet modify digestive enzymatic activity and protein digestibility.
