Vitamin A-deficient diet and its effects on certain haematological parameters of Heteropneustes fossilis a 3-4-dehydroretinol rich freshwater fish.
Effect of vitamin A-deficient diet on Heteropneustes fossilis results in anemia, loss of haemoglobin and erythrocyte, leucocyte and thrombocyte number, inhibition of synthesis of erythroblast along with the reduction of cytoplasmic and nuclear size of different blood corpuscles. Granulocytes are also affected, and although there is loss of granules and appearance of vacuolated lymphocytes, yet neutrophil, eosinophil and basophil show an increase in number, as examined after 90-100 days of administration of vitamin A-deficient diet.
