Application of functional additives in aquatic seedling feed

In aquaculture, healthy growth in the seedling stage is crucial to subsequent breeding benefits. The rational application of functional additives in aquatic seedling feed can significantly improve the growth performance and health level of seedlings and ensure the sustainable development of aquaculture.

There are rich and diverse types of functional additives, each with its own unique role. Bile acid is an important functional additive. It is the main component of bile and plays a key role in animal fat metabolism. Adding bile acid to aquatic seedling feed can help maintain liver and gallbladder and intestinal health and promote liver fat metabolism. Taking the health feed series of a certain aquatic group as an example, bile acid synergizes with other ingredients to increase the activity of digestive enzymes in the intestines, so that seedlings can fully absorb and utilize nutrients in the feed. In spring, when the water temperature is low and seedlings begin to feed, adding bile acid helps them adapt to the feed, improve early nutrient intake, and lay a good foundation for later growth.

Eucommia leaf extract is also a commonly used functional additive, which contains chlorogenic acid, eucommia polysaccharides, eucommia flavonoids and other ingredients. It can help remove free radicals and improve the immunity and stress resistance of seedlings. When seedlings face environmental changes or external pathogens, Eucommia leaf extract can enhance their resistance and reduce the incidence of disease.

Oligosaccharides such as glucan, mannooligosaccharide and peptidoglycan can regulate intestinal flora and ensure intestinal health. A healthy intestine helps seedlings to better digest and absorb feed and promote growth. Composite microecological preparations, such as lactic acid bacteria, Bacillus, and Streptococcus faecalis, also play an important role in regulating the balance of intestinal microecology, inhibiting the growth of harmful bacteria and creating a good intestinal environment for seedlings.

Under high-fat, high-protein and high-density breeding conditions, seedlings are prone to liver and gallbladder problems. Functional additives can help reduce the occurrence of these problems and are conducive to the healthy, safe and rapid growth of aquatic seedlings such as fish, shrimp and crabs. For example, in summer when the water temperature is high and the metabolism of aquatic animals is vigorous, adding bile acid can reduce the liver and gallbladder load, avoid diseases such as liver and gallbladder metabolic disorders, and ensure the growth rate and survival rate of seedlings.

The application prospects of functional additives in aquatic seed feed are broad. With the continuous advancement of science and technology, it is believed that more efficient and environmentally friendly functional additives will be developed and applied, bringing greater economic and ecological benefits to the aquaculture industry.
