Abstract

Potassium diformate has demonstrated effectiveness in enhancing growth performance of terrestrial animals
and improves the general health status of cultured animals by its stronger antimicrobial effect. Consequently, this study
was conducted to determine the effects of dietary organic acid salts as (potassium diformate) on growth promoters for
monosex 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 approximately
5±0.5 g, were divided equally between 4 different treatments with 3 replicates (10 fish / replicate). Fish were fed two
times 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 growth
performance, feed conversion ratio, feed efficiency, feed intake and survival of monosex tilapia fingerlings, compared to
the control group. In conclusion, these results revealed that using 0.3% KDF was the best in terms of growth performance
and economic analysis under this experimental condition.
