Dietary yeast RNA supplementation reduces mortality by Aeromonas hydrophila in rohu ( Labeo rohita L.) juveniles
A feeding trial was conducted for 60 days to delineate the effect of dietary ribonucleic acid or chitin on haematological parameters, phagocyte respiratory burst and resistance to Aeromonas hydrophila of Labeo rohita juveniles. One hundred and twenty-six (avg. wt. 13.40±0.17 g) juveniles were random...

| description | A feeding trial was conducted for 60 days to delineate the effect of dietary ribonucleic acid or chitin on haematological parameters, phagocyte respiratory burst and resistance to
Aeromonas hydrophila of
Labeo rohita juveniles. One hundred and twenty-six (avg. wt. 13.40±0.17 g) juveniles were randomly distributed in six treatment groups, each one in three replicates. Six isonitrogenous (crude protein: 34.34–35.37%) and isocaloric (414–425 kcal 100 g
−1) purified diets were prepared with different concentrations of either ribonucleic acid or chitin except the control group, viz., control, T1 (0.1% ribonucleic acid), T2 (0.2% ribonucleic acid), T3 (0.4% ribonucleic acid), T4 (25mg chitin kg
−1) and T5 (50 mg chitin kg
−1). Weight gain %, specific growth rate, feed efficiency ratio, protein efficiency ratio did not vary significantly (
P>0.05) among the experimental groups. Haemoglobin content and total erythrocyte count were observed within the normal range and were not influenced by the dietary immunostimulants. Highest total leukocyte count was found in the T
3 group. The immunomodulatory effects of dietary immunostimulants were studied by using nitroblue tetrazolium (NBT) assay and serum parameters, namely total protein, albumin, globulin and A/G ratio. The respiratory burst activity (NBT) of blood phagocytes was highest in the T3 group followed by the T2 group, which varied significantly (
