Soybean
Meal-Shrimp
A 30-day feeding study was conducted in Bangladesh to determine the
effects of incorporating a local soybean meal into the diet of P. monodon
postlarvae. Wild shrimps were collected, acclimated and stocked at twenty
per liter in thirteen-liter tanks with filtered seawater. Four test
diets with 40% protein and 10% fat were formulated using approximately
25, 35, 45 and 55% defatted soybean meal to replace fishmeal. The diets
were offered four times a day at a level calculated at 20% of the body
weight of the animals. Results indicated the 45% soybean meal treatment
supported significant higher weigh gains. The 55% soybean meal treatment
supported the lowest weight gains. Survival rates of 78.8, 74.2, 80.8
and 75% and feed conversion ratios of 1.10, 1.06, 1.13 and 1.04 were
found for the 25, 35, 45 and 55% soybean meal treatments. These results
indicate that local defatted soybean meal can be incorporated into diets
of P. monodon postlarvae up to 45% of the diet without significant decreases
in growth rates, survival or feed utilization.
