Abstract
This study aimed to investigate the effect of acidifying the diet of black tiger shrimp Penaeus monodon on its growth and feed efficiency by supplementing coconut sap vinegar CSV) or sugar cane vinegar (SCV) or their 1:1 combination. Three hundred and sixty post larva shrimps (average initial weight of 0.01g) were randomly distributed into 12 50-L plastic containers. Four experimental diets, namely, control diet, 2% CSV, 2% SCV and 2% CSV+SCV were fed to groups of shrimps. After 90 days, all shrimps fed with diets containing vinegar exhibited significantly higher final average body weight (FABW), weight gain (WG), feed intake, specific growth rate (SGR), and better feed conversion ratio (FCR) than those fed the control diet. Attractability tests showed that the CSV and CSV+SCV diets attracted significantly the highest percentage of shrimps after 10 min of feed placement. Survival rate was not significantly different among the treatments. In conclusion, the results demonstrated that the vinegars tested could be used as growth enhancers in shrimp and that the combination of coconut sap and sugar cane vinegars supplemented to the diet resulted in the best growth and feed efficiency as well as attracted the most percentage of shrimps.
