Abstract :

Lactococcus lactis, a Gram–positive bacterium was mixed in the diet feed of the catfish Pangasianodon hypophthalmus. The fishes were fed with this diet for a period of sixty days. Blood samples were collected with an interval of 15 days to study the haematological parameters such as total erythrocyte (RBC) count, total leucocyte (WBC) count, haematocrit (Hct), haemoglobin concentration (Hb), and haematological indices (MCV, MCH and MCHC). All the haematological parameters showed elevated levels than those in control group suggesting that Lactococcus lactis could be used as an efficient probiotic tool for better aquaculture practices.
