Stimulation of immunity in Indian major carp Catla catla with herbal feed ingredients

Catla catla, catla (150 ± 20 g) were fed a diet containing seed of Achyranthes aspera (0.5%) and control diet without A. aspera for four weeks prior to and after ip injection with chicken erythrocytes. Fish were sampled for four consecutive weeks after immunization. Hemagglutination antibody titers...

Description
Summary:Catla catla, catla (150 ± 20 g) were fed a diet containing seed of Achyranthes aspera (0.5%) and control diet without A. aspera for four weeks prior to and after ip injection with chicken erythrocytes. Fish were sampled for four consecutive weeks after immunization. Hemagglutination antibody titers were significantly higher in the test group of fishes compared with the control group. Serum globulin levels were significantly ( P t -test < 0.05) higher in the test group than control group on days 14 and 21. Anti-trypsin activity due to total serum protease inhibitors and α1-antiprotease was also significantly ( P t -test < 0.05) higher in the test group of fishes than the control. RNA/DNA ratio of spleen and kidney was also significantly ( P t -test < 0.05) higher in test group than the control group. All these results confirm that A. aspera enhances the immunity of catla.
