Utilization of vinegar-enriched diets in the growth and survival rate of giant

Acetic acid on vinegars has the capability to act as growth enhancers and prevents pathogenic bacteria. This study aimed to determine the growth and survival rate of Giant Freshwater Prawn (Macrobrachium rosenbergii) fed with vinegar-enriched diets. It was conducted within three trials with four experimental diets formulated: T0- control diet, T1- 2% (w/w) coconut sap vinegar(CSV), T2- 2% (w/w) apple cider vinegar (ACV) , and T3 - 2% (w/w) coconut sap vinegar + apple cider (CSV+ACV) with three replications each. Weight gain (WG), length gain (LG), specific growth rate (SGR), and survival rate (SR) were measured and data were analyzed using Analysis of Variance at p=0.05. Results demonstrated that individuals fed with diets containing CSV got the highest WG, LG and SGR. In terms of survival rate, those fed with diets containing CSV(T1) and ACV(T2) got 100% SR. Results showed that vinegar-enriched diets gained higher WG, LG, SGR, and SR compared with the control diet and were significantly different (p<0.05). In addition, diets supplemented with CSV resulted significantly the best growth among all diets and can be recommended to be supplemented into commercial feeds for better growth and survival of Giant Freshwater Prawn.
