Abstract:
The present study was designed to evaluate the effect of garlic (Allium sativum) powder on immunological parameters in fingerlings of amur carp (Cyprinus carpio haematopterus). Fingerlings with an average weight of 16.11± 0.86g were distributed randomly into four treatment groups in triplicates. Experimental diets were were prepared by mixing rice bran, deoiled mustard cake, deoiled soybean cake and vitamin-mineral mixture (28.0% protein and 7.5% lipid on dry matter basis). The dried garlic powder was incorporated at three concentrations (0.5%, 1.0% and 1.5%) in feed for conducting the experiment. Garlic powder was not added to the control diet. The experimental diets were fed to fish @5% of their body weight daily over the period of 245 days followed by challenge with Aeromonas hydrophila. Biochemical and immunological examination results indicated that the total serum protein, albumin, globulin, A/G ratio, aspartate aminotransferase (AST), serum alanine aminotransferase (ALT), lysozyme activity and nitro blue tetrazolium (NBT) assay varied significantly (P<0.05) between the pre challenge and post challenge groups. From the obtained results it can be concluded that garlic powder in the feed of Cyprinus carpio haematopterus can be safely incorporated upto 1.5% for enhanced immunity against aeromonad pathogens
