The present study aimed to determine the effect of ginger powder on the haematology of Oreochromis niloticus, and resistance to Aeromonas hydrophila infection. A completely randomized design was used for the experiment. A total of 300 healthy live experimental fish 20 ± 1.00 g of body weight and 11.06 ± 0.08 cm body length were randomly divided into five treatment glass aquariums. Each in triplicates, representing four treatments (3 g, 5 g, 8 g and 12 g ginger/kg diet) and one control (0.00 g/kg diet). After eight weeks of feeding trial 0.2 ml of A. hydrophila culture containing 1.0 × 107 CFU/ml (LD50) was given by Intra-peritoneal (IP) injection. Blood samples were collected before and after the bacte.. View more»
