Abstract
This study evaluated the impact of dietary Eucalyptus grandis leaf powder supplementation on growth performance and haematological parameters of Labeo rohita (rohu) fingerlings. One hundred and forty-four uniform rohu were randomly distributed into four experimental groups in triplicates. Iso-nitrogenous (30% crude protein) diets were prepared with graded levels of E. grandis leaf powder with 0% (C), 5% (T1), 10% (T2) and 15% (T3) and fed for 45 days. Water quality was monitored fortnightly. Growth performance and haematological indices were assessed. Results showed diets with 10% leaf powder significantly enhanced weight gain, feed conversion ratio, and specific growth rate compared to the control (p<0.05). The 10% group also exhibited elevated red blood cell counts, haemoglobin levels and white blood cell counts indicative of improved immune function. This research demonstrates that short-term dietary supplementation with 10% E. grandis leaf powder promotes growth performance and haematological health of rohu fingerlings. Further studies are warranted to elucidate the bioactive compounds responsible and evaluate long-term effects on production.
