Popis:	A 14-week feeding trial was conducted to determine the effects of dietary organic acids. The experimental diets were added with 0, 1, 2 or 3 g kg−1 of a novel organic acid blend or with 2 g kg−1 of potassium diformate and fed to triplicate groups of red hybrid tilapia (Oreochromis sp.). Upon completion, tilapia were challenged by immersion with Streptococcus agalactiae. There was no significant difference (P>0.05) in the growth, feed utilization and nutrient digestibility among treatment groups despite a trend towards improved results with fish fed organic acid-supplemented diets. Diet pH decreased, causing a reduction in the digesta pH of the stomach and gut. Total bacteria per gram of faeces were significantly (P
