Abstract

The Organic acids and probiotics play a vital role in the culture of many terrestrial and aquatic organism, these have gained prominence as alternative biomedicine to antibiotics. produced by the probiotic bacteria and are produced by leading manufacturers these have a number of applications in many fields such as Aquaculture, food preparations, poultry, sewage water treatment, animal feed production, human consumption. The effect of dietary supplementations of citric acid, formic acid, lactic acid or their salts improved the growth of Litopenaeus vannamei was studied. All the organic acids and probiotics studied enhanced the activity of the gut and pond ecosystem when compared with the control. The percentage of decrease in total vibrio count (TVC) when the feed mixed with (3p/kg and 5g/kg organic acid) and (2kg/ha and 3kg/ha of Probiotics) applied in Experimental pond A and experimental pond B respectively. The results have been promising with the variance clearing measured the number of colonies formed in the cultures obtained from Control pond(with as low as 0.24×102 ±0.27 to 40.21 ×10² ± 0.13 in the pond water) (with as low as 0.15×102 ±0.13 to39.23 × 10² ± 0.85 in the gut), similarly the observations in both the Experimental pond A and experimental pond B have been tabulated.
