Abstract

Potassium diformate has demonstrated effectiveness in enhancing growth performance of terrestrial animalsand improves the general health status of cultured animals by its stronger antimicrobial effect. Consequently, this studywas conducted to determine the effects of dietary organic acid salts as (potassium diformate) on growth promoters formonosex Nile tilapia fingerlings. Four experimental diets with three different inclusion levels of potassium diformate(KDF) (0.1, 0.3 and 0.5%) besides the control diet containing no KDF. A total of 120 tilapia, weighing approximately5±0.5 g, were divided equally between 4 different treatments with 3 replicates (10 fish / replicate). Fish were fed twotimes a day at rate 3% of body weight on a pelletized isonitrogenous diet containing 25% crude protein and isocaloric(gross energy 393 Kcal/100g). The results indicated that the addition of 0.3% KDF had a significantly higher growthperformance, feed conversion ratio, feed efficiency, feed intake and survival of monosex tilapia fingerlings, compared tothe control group. In conclusion, these results revealed that using 0.3% KDF was the best in terms of growth performanceand economic analysis under this experimental condition.
