The purpose of this research was to study the effect of different ratio levels of combination between formaldehyde and antioxidant as microorganism and oxidation control on full fat fish meal. The experimental combinations feed additive were formulated based on hhe experiment was done following a 3x3 factorial design based on three ratio levels of formaldehyde (0, 200 ppm and 400 ppm), and three ratio levels of antioxidant (Vitamin E and Mineral Se) (0, 200 ppm and 400 ppm). Each combinations treatment had four replications. The influence was shown significant (P<0.05) on oxidations number and bacterial growth.
