Abstract: A 60 days feeding trial was performed to assess the effects of fenugreek (<em>Trigonella foenum-graecum</em>) on the growth performance, haematological and immunological response in Nile tilapia (<em>Oreochromis niloticus</em>) fry. Five diets incorporating fenugreek diet at 0, 0.5, 1, 1.5 and 2% were prepared. The results showed that fenugreek diet in feed led to significantly (p&lt;0.05) improved survival, weight gain and feed efficiency for treated groups over the control. Dietary fenugreek significantly (p&lt;0.05) increased erythrocytes, leucocytes, haematocrit, haemoglobin in treated fish. Significantly higher (p&lt;0.05) serum protein, albumin and globulin levels were observed in treated groups over the control. In conclusion, the impact of fenugreek has shown effective therapeutic results to consider incorporating this plant in fish feed. Also it was possible to meet the dietary fenugreek requirement of tilapia that was estimated to be 0.98 g/kg and 0.99 on the basis of maximum weight gain and protein efficiency ratio respectively.
