Nội dung bài viết trình bày nghiên cứu cho thấy, thức ăn lên men lỏng có thể được chế biến cho các khẩu phần hỗn hợp hoàn chỉnh hoặc cho từng nguyên liệu thức ăn riêng rẽ. Chất lượng của thức ăn lên men lỏng phụ thuộc vào hàm lượng axit lactic hình thành trong quá trình lên men tự nhiên hoặc nhờ giống khởi động.

Effects of carbon sources on growth performance and survival rate of larval rearing of the freshwater prawn Macrobrachium rosenbergii by biofloc technology Le Thanh Nghi Pham Minh Truyen Chau Tai Tao Nguyen Van Hoa Tran Ngoc Hai Abstract This study aimed to identify suitable carbon sources for the growth and survival of larva and postlarva of giant freshwater prawn nursed in tanks with biofloc technology. The experiment was conducted with four treatments i no carbon supplement control ii carbon supplement from rice flour iii carbon supplement from rice bran and iv carbon supplement from sugar. Each treatment was triplicated. The experimental tank was 500 liters in volume. Stocking density was 60 larvae liter and water salinity was 12 . The result showed that after 35 days rearing the environmental parameters bacterial density bioflocs during the rearing of the treatments were in a suitable range for shrimp growth and development. The sugar treatment the body length of PL-15 mm survival rate and productivity 35 573 5 219 postlarva m3 was the highest and .
