White Mulberry (Morus alba)‎ Foliage Methanolic Extract Can Alleviate Aeromonas hydrophila Infection in African Catfish (Clarias gariepinus)‎

Abstract EN

Two experiments were simultaneously conducted with Morus alba (white mulberry) foliage extract (MFE) as a growth promoter and treatment of Aeromonas hydrophila infection in separate 60 and 30 days trail (Experiments 1 and 2, resp.) in African catfish (Clarias gariepinus).

In Experiment 1, four diets, control and control supplemented with 2, 5, or 7 g MFE/kg dry matter (DM) of diet, were used.

In Experiment 2, fish were intraperitoneally infected with Aeromonas hydrophila and fed the same diets as experiment 1 plus additional two diets with or without antibiotic.

Results of experiment 1 showed that growth was unaffected by dietary levels of MFE.

Treatments with the inclusion of MFE at the levels of 5 and 7 g/Kg DM had no mortality.

Red blood cells (RBC), albumin, and total protein were all higher for the treatments fed MFE (5 and 7 g/Kg DM).

Results of experiment 2 showed RBC, hemoglobin, hematocrit, globulin, albumin, and total protein improved with the increase in MFE in the infected fish.

The dietary MFE at the level of 7 g/kg DM reduced mortality rate.

In conclusion, MFE at the level of 7 g/kg DM could be a valuable dietary supplement to cure the infected fish.
