Description:
The present study was conducted to examine different dietary levels of iron (FeSO4) on
some haematological parameters of ship sturgeon, Acipenser nudiventris including red
blood cells (RBC), white blood cells (WBCs), differential WBCs, hematocrit (Hct),
Hemoglobin (Hb), the mean corpuscular hemoglobin (MCH) and the mean corpuscular
hemoglobin concentration (MCHC), the mean corpuscular volume (MCV),
immunoglobulin (IgM), ferritin, transferrin and plasma Fe^2+. Four experimental
treatments and one control group with three replicates were considered for the
experiment. The experimental treatments were fish fed experimental diets containing
different levels of FeSO_4 i.e. 100, 200, 250, and 300 mg kg.diet^-1
. After 60 days, there
were significant differences between experimental groups in terms of WBCs,
lymphocytes, neutrophils, monocytes, eosinophils, MCH and MCHC, MCV, total
plasma protein, IgM, ferritin, transferrin and plasma Fe^2+ (p〈0.05). In the treatment fed
100 mg.iron kg.diet^-1
, more levels of IgM and total plasma protein were observed
compared to other experimental groups (p〈0.05). The highest values of neutrophils,
monocytes and MCHC were found in control fish whereas MCV, MCH and eosinophils
values were higher in the treatment fed 200 mg.iron kg.diet^-1
(p〈0.05). Also, more
WBCs were observed in 250 mg.iron kg.diet^-1
treatment than in other groups (p〈0.05).
The values of lymphocytes, RBC, Hct, Hb, ferritin, transferrin and plasma Fe^2+ were
higher in fish fed 300 mg.iron kg.diet^-1
compared to other experimental groups
(p〈0.05). In conclusion, our results showed that the supplementation of ship sturgeon
diets with high levels of iron enhances the RBC, Hct, Hb, ferritin, transferrin and
plasma iron.
