Abstract: A 245 days experimental study was carried out to investigate the supplemental effects of dietary garlic (Allium sativum) powder on haematological parameters in fingerlings of amur carp (Cyprinus carpio haematopterus). Fingerlings with an average weight of 16.11± 0.86g were distributed into four treatment groups T1, T2, T3 and T4 (25 fishes randomly distributed in each of 12 tanks). The experimental feed diets were isoproteinous and contained 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. The experimental diet was fed to fish over the period of 245 days followed by challenge with Aeromonas hydrophila. The value of total erythrocyte count did not vary considerably (p>0.05) within T₁ and T₂, T₃ and T₄ in pre challenged group and T₃ and T₄ in post challenged group. The total leucocyte count and haemoglobin resulted in significant (p< 0.05) increment between pre challenge and post challenge in all treatment groups. The water quality parameters like pH, dissolved oxygen, temperature, free carbon dioxide and total alkalinity were within the tolerance range of the experimental fish, Amur carp. It is inferred from the results of the study that dried garlic powder can be safely incorporated up to 1.5 % in carp feeds for improved haematological profile in Amur carp.
