Abstract: (2471 Views) |
The present study examined the effect of date pits powder as a low-cost and nutritive carbohydrate source compared to wheat, rice and corn meal in the diet of Pacific shrimp. The date pits meal was applied to the diet at the levels of 0 (control group), 5, 10, 15 and 23%, and the growth performance of shrimp was examined in 8 weeks. The results showed that the weight and length gain, specific growth rate (SGR), and condition factor of shrimp fed diets contained different levels of date pits meal were not significantly different compared to control group (p>0.05). The condition factor was close to 1 in all the treatments. Altogether, this study showed that the date pits meal could be applied up to 20% as an endemic and low-cost carbohydrate source in the diet of farmed shrimp and replaced by other energy providing sources including wheat meal without any adverse effect on shrimp performance.
