Abstract

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 0.82Â±0.08g were randomly stocked in 45 aquarium tanks with a working volume of 50 L (60Ã—40Ã—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.

Highlights

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
Potassium diformate(KDF) known as K-diformateis a salt obtained by a specific technologyof neutralizing Kdiformatec acid with potassium hydroxideand stabilizing its carboxylic anion under pressure (Mrozet al., 2002)
Potassium diformate is generally appeared in the nature and digestive tract of pigs which readily utilized by terrestrial animal

Summary

Introduction

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. Plenty of researcher in Europe showed good evidence on pig’s growth performance as a growth promoter but the study on aquatic animal is still absence. The optimum level of dietary protein for white shrimp was determined to be 36% by Smith et al (1985) with three different sizes of white shrimp (4.0, 9.8 and 20.8g and later revised by Lee and Lee (2018) in their study they reported the optimal dietary level of crude protein to be 34.5, 35.6, and 32.2% for small, medium,and large-sized white shrimps. Xia et al (2010) reported that a dietary protein level of around 43% could be optimum for the rearing of L.vannamei in a high-density culture system in the absence of natural productivity
