DOES K-DIFORMATE SUPPLEMENTATION IMPROVES GROWTH AND DIET STAIBLITY OF JUVENILE WHITE SHRIMP(LITOPENAEUS VANNAMEI)?

A study was conducted to investigate the effects of potassium diformate (K-diformate) supplementation in two protein levels on growth, food conversion and survival in juvenile white shrimp, litoppenaeusvannamei.Two dietary protein levels, 41% dietary protein(CP41) and 37% dietary protein(CP37) was formulated and supplemented of graded K-diformate levels 0%, 0.1%, 0.2%, 0.4%, 0.8%, 1.4% and 2.0%.Post larvae white shrimp (Litopenaeusvannamei) of initial mean weight 0.82±0.08g were randomly stocked in 45 aquarium tanks with a working volume of 50 L (60×40×30 cm ) at a stocking density of 10 shrimps per aquarium.The result of this study did not show significant difference in percentage weight gain and survival rate among shrimps fed CP41 and CP37 with graded K-diformate supplemented diet. No K-diformate dose response was observed at the end of the study. The results of present study proof that K-diformate supplemented diet do not affect water pH and feeding diet stability in water.
