| description |
The present research was conducted to investigate the effects of fish oil (FO)
substitutions with corn oil (CO) and lipid levels on the gonad development of Tor
tambroides broodstocks via three feeding trials. The first feeding trial was conducted
to examine the effects of diets containing various FO and CO ratios on female T.
tambroides broodstocks. Three isonitrogenous (450 g kg-1 crude protein) and
isolipidic diets (105 g kg-1 crude lipid) were formulated to contain FO and CO at
ratio of 1:0 , 1:1, and 0:1, respectively and was fed to the female broodstocks for five
months. Based on the gonadosomatic index (GSI), hepatosomatic index (HSI),
histological observations on the gonad cell, muscle fatty acids (FA) composition, and
17β-estradiol (E2) level, fish fed with diet containing FO to CO ratio of 1:1
demonstrated higher GSI and the farthest development of gonad cell stages for
female T. tambroides with ratio of n-3 to n-6 of 0.74. To further elucidate the effects
of lipid on T.tambroides broodstocks, the second and third feeding trials were
conducted with isonitrogenous (450 g kg-1 crude protein) diets containing 60, 82,
105 and 128 g kg-1 of lipid (0, 2.5, 5.0 and 7.5% lipid inclusion respectively) with
FO to CO ratio of 1:1 on female and male T. tambroides broodstocks respectively,
for five months. |
