Effects of dietary pyridoxine on haemato-immunological responses of Labeo rohita fingerlings reared at higher water temperature . A sixty-day feeding trial was carried out to elucidate the effect of dietary pyridoxine ( PN ) on hemato-immunological parameters in Labeo rohita fingerlings exposed to an elevated temperature ( ET ) of 33 °C . Two hundred and seventy fingerlings ( 6.71 ± 0.32 g ) were randomly distributed into six treatments in triplicates ( 15 fish/tank ) . Five iso-nitrogenous ( 356.3 ± 2.7 g/kg crude protein ) purified diets were prepared with graded levels ( 0 , 10 , 50 , 100 and 200 mg/kg diet ) of PN . Six treatment groups were P10T26 ( 10 mg PN + ambient temperature ( 26 °C ) , P0T33 ( 0 mg PN + ET ) , P10T33 ( 10 mg PN + ET ) , P50T33 ( 50 mg PN + ET ) , P100T33 ( 100 mg PN + ET ) and P200T33 ( 200 mg PN + ET ) . The responses of L. rohita fingerlings to dietary PN were assessed in terms of growth and by analysing some hemato-immunological parameters . When PN supplementation increased from 10 to 200 mg/kg diet , a significant improvement in weight gain percentage was observed . Erythrocyte ( RBC ) count , leucocyte ( WBC ) count , haemoglobin content and respiratory burst activity were significantly ( p < 0.05 ) higher in 100 mg PN/kg diet-fed group than their non-PN-fed counterpart . Also , serum albumin , globulin and lysozyme activity were found significantly ( p < 0.05 ) higher in PN-fed groups . The overall results indicated that dietary PN supplementation at 100 mg/kg diet may reverse the negative effects caused by ET and may protect the haemato-immunological status of L. rohita fingerlings reared at higher water temperature .
