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.

“…In the present study, dry matter and protein contents in whole body were significantly influenced by the dietary vitamin B 6 levels, and shrimp fed the diets supplemented vitamin B 6 had a relative higher dry matter and crude protein contents in whole body than those fed the diets without supplemental vitamin B 6 as observed by Giri et al . () in Penaeus japonicus juvenile. However, lipid and ash contents were not significantly affected by the dietary vitamin B 6 levels.…”

Six diets were formulated with vitamin B 6 levels (2. 6, 32.7, 54.8, 90.7, 119.6 and 247.4 mg kg À1 , dry diet) to determine the requirement for juvenile Pacific white shrimp, Litopenaeus vannamei. Triplicate groups of 40 juvenile shrimp (approximately 1.0 g) were provided four times each day to apparent satiation (8 weeks). Weight gain (WG), specific growth rate, feeding efficiency, protein efficiency ratio (PER) and protein productive value of the shrimp were significantly influenced by the vitamin B 6 levels. No significant differences in whole-body and muscle composition, except for dry matter and protein contents in whole body. Vitamin B 6 concentration in the hepatopancreas significantly increased with the dietary vitamin B 6 level increasing from 2.6 to 32.7 mg kg À1 . High-density lipoprotein cholesterol in the haemolymph improved with the dietary vitamin B 6 levels increasing from 2.6 to 90.7 mg kg À1 diet and no significant differences in low-density lipoprotein cholesterol, cholesterol, glucose and total protein concentrations. Aspartate aminotransferase, alanine aminotransferase, superoxide dismutase, catalase and lysozyme in the haemolymph were significantly influenced by dietary vitamin B 6 levels. The optimal dietary vitamin B 6 requirements estimated using a two-slope broken-line model based on WG and SGR and an exponential model based on the vitamin B 6 concentration in the hepatopancreas were 110.39, 110.08 and 167.5 mg kg À1 , respectively.

“…It functions as the precursor of the coenzyme (pyridoxal 5-phosphate and pyridoxinamine 5-phosphate), which is required for more than 100 enzyme reactions. Among them, the most important is to act as the coenzyme of aminotransferase and decarboxylase in the reactions of amino acid and nitrogenous compounds [1,2]. Furthermore, previous studies reveal that PN is involved in the antioxidant reaction [3] and the synthesis of DNA and RNA [4,5], and also regulate the gene expression of glucocorticoid hormone and albumin [6,7].…”
