58-62The effect of exclusion of individual water-soluble
(thiamine, riboflavin, pyridoxine, cyanocobalamin, pantothenic acid, folic acid,
niacin, biotin, choline, inositol, ascorbic acid) and fat-soluble vitamins (vit.
A, D, K and E) in semi-purified diets on growth and survival of juvenile shrimp,
P. monodon was studied in the laboratory for 8 weeks. Diets Jacking
riboflavin and vitamin K did not affect
growth and survival of shrimp. However, deletion of inositol and choline resulted
in poor growth. Maximum growth was observed in the control diet (Cl) which was supplemented
with all vitamins. Diet deficient in ascorbic acid, biotin, folic acid, niacin,
thiamine and α-tocopherol resulted in poor appetite and poorer feed
conversion efficiency. All treatments except
the control (Cl) resulted in histological changes in the digestive gland cells.
Detachment or destruction of the epithelial cells was observed in all treatments
lacking individual vitamins but more severely in the treatment without a
vitamin supplement followed by inositol, choline and ascorbic acid deficient
diets
