Abstract
In the present study, an attempt was made to appraise the curative potential of locally available plant Helianthus annuus leaf powder against Aeromonas hydrophila, a bacterial pathogen of Labeo rohita. The experimental feed was prepared using different concentrations of H. annuus leaf powder (0.5g, 1g, 1.5g, 2g and control) and the same were fed to L. rohita fingerlings infected with A. hydrophila, individual group wise for 28 days. The effects of different concentrations of feed containing leaf powder of H. annuus on Haematological, Biochemical and Enzyme parameters in the blood of L. rohita fingerlings infected with A. hydrophila were studied. The results indicated that the parameters of the infected fish gradually improved from abnormal to normal levels at the cessation of the 28th day of experiment in the blood of fish. This change might be attributed to the intake of H. annuus leaf powder, containing feed. The results of the present investigation apparently suggested that the selected plant’s leaf powder had curative potential against A. hydophila infected L. rohita fingerlings. Therefore, it may be concluded that the H. annuus @ 2.0 g concentration in the diet of L. rohita fingerlings can be fed to cure the bacterial infection, particularly, A. hydrophila.
