Yellow catfish feed additive

Abstract

The invention discloses a yellow catfish feed additive. The yellow catfish feed additive is prepared from, by weight, 10-35 parts of penthorum chinense pursh, 5-40 parts of alga extract powder, 5-40 parts of cortex moutan, 1-15 parts of fennel powder, 5-30 parts of hawthorn fruits, 1-8 parts of spirulina powder, 1-20 parts of galic, 0.01-3 parts of mineral substances, 1-15 parts of pericarpium citri reticulatae powder and 5-10 parts of fructus lycii. According to the yellow catfish feed additive, the raw materials are in reasonable compatibility, deposition of fat in the liver and abdomen of yellow catfish can be remarkably reduced, and the symptoms of the fatty liver and liver edema of yellow catfish can be relieved; the feeding rate of yellow catfish can be remarkably increased, and very good liver protection, and fat liver prevention and treatment effects are achieved on bred yellow catfish. Experiment results indicate that when the feed additive is added into feed for yellow catfish with high fat content at the dosage of 8-12%, the fish liver and body ratio in experiments is reduced by 5-8%, the abdomen fat coefficient is reduced by 2-5%, the liver edema is remarkably relieved, and the food intake is improved by 10-15%.

Problems solved by technology

Uneven nutrient intake can easily lead to fat accumulation in the liver and abdominal cavity. The artificial compound feed for yellow catfish currently available in the market is too low-cost, reduces the content of high-quality protein, makes the feed nitrogen unbalanced, and lacks key nutritional factors. Addition of anti-adipogenic factors did not pay enough attention, resulting in frequent occurrence of nutritional fatty liver disease in cultured yellow catfish
