Notes:
The immunomodulatory effects of dietary administration of 3,3′,5-triiodo-l-thyronine (T3) at 0, 1, 5 and 10 mg kg−1 of diet for 60 days in rohu (Labeo rohita) fingerlings were studied. Oral administration of T3 at all dose levels resulted in significantly (P〈0.05) higher serum T3 levels, total serum protein and globulin levels, and reduced albumin–globulin ratio (A : G) compared with the control group, whereas feeding of T3 at 5 and 10 mg kg−1 diet enhanced the growth and superoxide production by neutrophils. At the end of the 60-day experimental period the optimum dosage of T3 appeared to be the 5 mg kg−1 diet for rohu fingerlings, resulting in a significantly higher specific antibody titre against formalin-killed Aeromonas hydrophila and lowering the mortality percentage against the A. hydrophila challenge.
