Dietary Oil Sources on the Innate Immunity and Resistance of Nile Tilapia, Oreochromis niloticus, to Streptococcus agalactiae Challenge

The effect of different dietary oil sources on the innate immunity and resistance of Nile tilapia, Oreochromis niloticus , to Streptococcus agalactiae infection were evaluated. Fish were fed with diets containing different lipid sources (soybean oil [ SO ], corn oil, linseed oil [ LO ], fish oil [ FO ], and olive oil [ OO ]).
