New Ideas for the Development of Aquatic Functional Feed

1. Aquatic Functional Feed Background

With the continuous breakthrough and improvement of aquaculture technology, it has brought many new opportunities for the rapid development of aquaculture, but it has also brought many new problems and difficulties. The healthy growth, quality and safety of farmed animals are seriously threatened by the degradation of seedlings, the imbalance of feed nutrition, the increasing stocking density, the deterioration of the breeding environment and the abuse of antibiotics.

For example, perch and raw fish nocartosis, Pelteobagrus fulvidraco cleft head disease, fork tail catalepsy, golden pomfret high temperature enteritis, large yellow croaker white gill, crucian carp red gill, grass carp hemorrhage, tilapia streptococcus and so on occur frequently, making farmers miserable. According to incomplete statistics, the annual economic losses caused by diseases of aquaculture animals are close to 20 billion in recent years, causing huge economic losses.

The fundamental purpose of developing aquatic functional feed is to meet the needs of rapid growth, safety and health of aquaculture animals to the maximum extent. This is both a challenge to the aquaculture industry and an opportunity for feed companies. Functional feed was born in this context. Whoever has mastered the feed formula model that promotes the growth and health of aquatic animals, and has related products, can differentiate and break through in market competition!

2. what is aquatic functional feed

Aquatic functional feed refers to the feed with a specific function produced in order to improve the quality of feed or increase the use of feed. It can regulate the metabolic function or immune function of the body, so as to improve the production performance or health level of farmed animals, and finally achieve the requirements of rapid and healthy growth of farmed animals.

Classification of Aquatic Functional Feed in 3.

According to the functional differences of functional feed, they are divided into drug feed and health feed.

Among them, drug feed can be divided into preventive drug feed and therapeutic drug feed. They are made by adding disease prevention and treatment drugs in the feed. They are mainly used to prevent and treat aquatic animal diseases and are rarely used at ordinary times. Only in the epidemic season can they be reasonably selected according to the disease condition.

Health feed is made by adding some functional additives to the feed, they are mainly used for animal health and some skills of regulation, usually do not have the function of treating diseases, can not replace the use of drugs.

According to the stage of use of functional feed and application scenarios, it is divided into the following types:

1, seedling stage feed (digestive system hypoplasia, poor resistance), pay attention to the product's digestibility, disease resistance and disease prevention and intestinal mucosa maintenance, etc;

2. New feed to meet the needs of anti-stress and health maintenance; Functional feed in high incidence period of epidemic disease (repair of liver and intestinal damage);

3, overwintering and other special periods of functional feed, lure food, fattening, reduce overwintering weight loss;

4. Functional feed for improving meat quality and body color;

5. Fermented feed, regulate intestinal ecological balance and strengthen immunity.

Status and Analysis of Aquatic Functional Feed in 4.

At present, some functional products have been introduced to the market. For example, Aohua has launched "Shrimp Milk Powder" and "Yumibao" for fish and shrimp, Tongwei's "Shrimp Liver Strength" for shrimp feed, and "Carp Double Health", "Fish Intestinal Health" and "Vitality Health" for fish feed. In addition, many enterprises have produced a series of functional feeds using micro-ecological raw materials or additives, such as sea fish jianle, Australian Chinese shrimp Ankang, Tianbang fermented flavor feed, etc.

From the perspective of product design ideas and future product competition of large enterprises at this stage, the market of feed products will be more refined, and functional feed for specific growth stages and specific breeding problems will win a certain market.

Take a certain aquatic group health care feed series as an example, it is understood that its main components include 4 categories:

1. Basic nutrition: imported fish meal, fermented meal, yeast, high-quality fish oil, soybean oil, complex vitamins, polypeptide amino acids, various trace elements;

2. Immune-enhancing additives: bile acids, amino acids, oligosaccharides (dextran, mannan oligosaccharides and peptidoglycan);

3, protect the liver and gallbladder, promote fat absorption: bile acid;

4. Compound probiotics: Clostridium butyricum, lactic acid bacteria, Bacillus, Streptococcus faecalis, etc.

As the basis of feed nutrients (fish meal, yeast) almost does not contain anti-camp factors, nutritious and easy to digest, high utilization rate.

In addition to satisfying the function of providing nutrition, the feed adds other 3 types of substances. These substances have synergistic effects in function. For example, compound amino acids and algae extracts can help scavenge free radicals, improve body immunity and resist stress. Bile acid can help protect liver and gallbladder health and enhance liver fat metabolism. Probiotics can help regulate intestinal flora and intestinal health.

These substances play a role in improving immunity, protecting the liver, resisting stress, and promoting digestion, promoting the healthy growth of farmed animals, reducing the probability of morbidity, reducing the death of a fish or shrimp, earning more money, and giving farmers Really increase economic benefits.

What is the market prospect of aquatic functional feed in 5.

In short, functional feed should be problem-oriented, and everything should be measured by simplicity and effectiveness. We don't talk about the level of protein but the effectiveness of protein, and we don't talk about the types of additives but the effectiveness of additives for problems. High utilization of protein raw materials is the foundation, effective additives are the key, and good breeding effect is the result of the pursuit.

With the continuous improvement of national income and consumption level, the demand for aquatic products has changed from quantity type to quality type, which is manifested in the growth of demand for green, safe, nutritious and delicious functions of aquatic products. Therefore, the research and development of aquatic functional feed will become the inevitable trend of the development of aquatic feed industry, and it is also an effective measure to promote the healthy and sustainable development of aquaculture industry. Therefore, the application of functional feed will become the direction of the development of the aquaculture industry in the future, and its prospects are undoubtedly very broad.
