Adding organic acid in food be considered is an effective method for disease prevention, promoting growth, and decrease coefficients of Feed Conversion Rate (FCR), helping increase productivity in the farming process.
However, directly bring organic acid or salt of organic acid into aquafeed, especially industry food is also a completely new technique. The organic acid or salt of organic acid added in aquafeed usually consist of lactic acid and sodium lactate, acid acetic and sodium acetate, acid propionic and sodium propionate, acid formic and sodium formate or potassium deformity…
The research related to organic acid and aquatic animals that recently focus on the ability to enhance the absorption of phosphor and other minerals. In addition, they also have other functions such as inhibiting the growth of harmful microorganisms (mold, yeast, and bacteria) to survive in habitat, in food, and in the aquatic animal body. Then, reducing pH in the stomach, especially in the small intestine, separates in bacterial cells and the accumulation of anion inhibits the growth of gram-negative bacteria.
Add organic acid in food leading to low pH at the duodenum, improve nitrogen retention, and increase the digestibility of nutrients so improve growth speed and decrease coefficients of Feed Conversion Rate.
the organic acid applied research in the food of black tiger shrimp to evaluate the growth performance and nutrient retention efficiency of black tiger shrimp fed organic acids (butyrate, succinate, and fumarate), single (10g/kg) or in combine (30g/kg) and control treatment did not add organic acid.
After 42 days, the survival rate significantly higher in the treatment method BUT and additional combination compared with the control experiment.
Adding butyrate, succinate, and combine show that the feed efficiency using is more decreased than the control group. (1.3 -1.7 compared with 2.4 at the control experiment.)
Additional treatments butyrate and additional combine all have higher biomass than succinate, fumarate, and control experiments (28,3kg compared with 11,2-1919g). The result also shows that the close relationship between increase biomass and the total amount of food in the diet treatments.
The addition succinate, butyrate, and additional combine to increase overall nutrient retention efficacy compared to control, with butyrate and the additional combine shows the highest total nutrition for all macronutrients are checked( crude protein= 26,7% and 24,6% compared with 15,3% total liquid = 19,2@ and 17,7% compared with 10,6% ash = 25,1% and 23,1% compared with 12,2% and total power =17,7% and 16,3% compared with 10,2%).
Finally, the additional combine with an organic acid (fumarate, butyrate, and succinate) with a dose of 30g/kg food and add butyrate 10g/kg that live rate improved, strengthen immunity, stimulus growth, and effect of nutrient retention in black tiger shrimp.
