The study investigated the efficacy of varying inclusion levels of oxalic acid on
growth performance, carcass composition of Oreochromis niloticus and challenge
test with Escherichia coli. O. niloticus of mean weight 7.00g ± 0.04 were fed with
varying oxalic acid supplemented diets for 90 days. At the expiration of the feeding
trials significant variations was recorded on growth performance indices and
carcass composition of fish. The best growth was recorded in OAC4 which also had
best protein retention. The culture water parameters (DO2, temperature, pH) were
with the required limits. The study demonstrated that oxalic acid at 1.5% was able
to improve growth and had highest survival in challenge test with E. coli.
