The "Crown Series" is a kind of microencapsulated feed. It adopts advanced low-temperature forming and low-temperature drying technologies to obtain feed pellets with uniform and round appearance. With the bionic ecological technology, it has good suspension in water, and the water resistance time can reach more than 24 hours, which is very suitable for use in the stage before P5 of shrimp larvae. The exquisite technology avoids the nutrient loss caused by the high-temperature, high-pressure and high-humidity granulation process of conventional feeds, perfectly locking in every bit of nutrition!
The three major advantages of microcapsules are:
1. Strong attractiveness to feeding → It adopts various fresh Antarctic krill powders and deep-sea squid oils to simulate the unique taste of biological feeds and fully stimulate the taste system of shrimp larvae.
2. Comprehensive nutrition → Create an all-round excellent high-end complete feed to meet the needs of the shrimp seedling stage; select an advanced low-temperature microparticle production process to avoid nutrient loss; comprehensively meet the growth nutrition and immune enhancement needs of the shrimp seedling stage.
3. High immunity → Add immune enhancers such as antioxidant yeast selenium, β-glucose, and astaxanthin to create an all-round seedling feed.
Serious water pollution, heavy labor intensity and uneven quality of seedlings are the biggest problems faced by the current shrimp larvae breeding industry in China. In the stages of zoea, mysis and postlarvae, except for a small amount of use of biological feeds such as rotifers and brine shrimp, shrimp flakes are mainly used for feeding. When using them, they need to be wrapped with gauze, rubbed and filtered in water before being splashed and fed, which requires a large amount of labor from the workers.
It is known that the main raw materials for producing shrimp flakes are conventional raw materials such as fish meal, soybean meal and peanut meal. Moreover, due to the lack of research, shrimp flakes have basically not formed standardized products at present, and the formulas of different manufacturers vary greatly, which also leads to the uneven quality of shrimp flakes. In addition, since the production of shrimp flakes requires a high temperature of more than 500 degrees Celsius, many heat-sensitive nutrients will be lost during the processing process, and even many enterprises do not add heat-sensitive substances such as vitamins and fish oil when producing shrimp flakes.
Microencapsulated feeds are complete feeds, and the main raw materials are brine shrimp powder, fish meal, multiple vitamins, minerals, etc. The production of microencapsulated feeds not only needs to consider the comprehensive nutritional formula but also the bulk density of raw materials to ensure strong suspension. Therefore, during the 6-year promotion process, we have been constantly improving according to the actual usage situation, and now the technologies in all aspects are very mature and can be fully promoted to the market." said Sun Ruijiao. Summarizing the promotion situation of microencapsulated feeds in the past 6 years, she believes that microencapsulated feeds can be directly fed during the use process, which saves a lot of manpower, and they are nutritionally comprehensive with less waste, greatly reducing the pollution to water bodies.
