BỔ SUNG POLYSACCHARIDES CHIẾT XUẤT TỪ RONG BÚN (Enteromorpha intestinalis) VÀO THỨC ĂN ƯƠNG TÔM THẺ CHÂN TRẮNG (Litopenaeus vannamei)

The study was conducted to evaluate the effects of dietary supplementation of polysaccharides extracted from the seaweed (Enteromorpha intestinalis) at different levels on the growth, survival rate, feed utilization efficiency, and stress resistance of white-leg shrimp (Litopenaeus vannamei) during the nursery phase. White-leg shrimp (initial weight 0.02±0.005 g) were fed a control diet without the seaweed extract, while the other treatments included diets supplemented with the extract at levels of 0.4% and 0.8%. After 30 days of rearing, the results showed that shrimp-fed diets supplemented with 0.4% and 0.8% of the seaweed extract exhibited faster growth, better feed conversion ratio, higher protein efficiency, and improved salinity stress resistance compared to the control. In conclusion, the findings indicate that supplementing shrimp feed with 0.4% Enteromorpha intestinalis extract enhanced the efficiency of shrimp nursery. Tra cứu Dịch Đang tìm kiếm ...
