Description Not Available
A 60 - day feeding trial was conducted to
study the effect of dietary microbial levan on growth
performance and metabolic responses of Cyprinus
carpio fry exposed to sublethal dose (1/10th LC50) of
fipronil [(±) - 5 - amino - 1 - (2,6 - dichloro - a,a,a - trifluorop -
tolyl) - 4 - trifluoromethylsulfinylpyrazole - 3 - carbonitrile].
Two hundred and twenty five fry were randomly
distributed in five treatments in triplicates. Four
purified diets were prepared with graded levels of
microbial levan. Five different treatment groups were
levan control L0P0 (basal feed ? 0 % levan without
exposure to pesticide); pesticide control L0P1 (basal
feed ? 0 % levan with exposure to pesticide); L0.25P1
(basal feed ? 0.25 % levan with exposure to
pesticide); L0.50P1 (basal feed ? 0.50 % levan with
exposure to pesticide); and L0.75P1 (basal feed ?
0.75 % levan with exposure to pesticide). Weight
gain% and specific growth rate were significantly
higher (p\ 0.05) in levan fed groups compared to
their non - levan fed counterpart. Highest (p\ 0.05)
content of ascorbic acid in muscle, liver and brain
tissues was observed with higher level of dietary
levan. Glucose - 6 - phosphate dehydrogenase activity
decreased with the increasing level of dietary levan
in the liver and muscle. Aspartate aminotransferase
activity exhibited a second order polynomial
relationship with the dietary levan, both in liver
(Y = - 1.001x2 ? 5.366x ? 5.812, r2 = 0.887) and muscle (Y = - 0.566x2 ? 2.833x ? 6.506, r2 = 0.858)
while alanine aminotransferase activity showed third
order polynomial relationship both in liver (Y =
1.195x3 - 12.30x2 ? 35.23x ? 9.874, r2 = 0.879)
and muscle (Y = 0.527x3 - 8.429x2 ? 31.80x ?
8.718, r2 = 0.990). Highest (p\ 0.05) superoxide
dismutase activity in gill was observed in the group fed
with 0.75 % levan supplemented diet. Overall results
indicated that dietary microbial levan at 0.75 % in
C. carpio fry ameliorated the negative effects of
fipronil and augmented the growth.
