Special compound feed for sturgeon, and preparation method thereof

Abstract

The invention relates to a special compound feed for sturgeon and a preparation method thereof, which is made of the following raw materials in percentage by weight: 28-40% of soybean meal, 20-25% of secondary meal, 25-35% of fish meal, and 7-9% of fish oil , shrimp powder 6-7%, salt 0.2-0.4%, choline 0.1-0.3%, sturgeon special feed additive 0.9-1.5%, the sum of the weight percentages of the above raw materials is 100%. Adopting the special compound feed for sturgeon of the present invention can significantly improve the economic benefits of artificially cultured sturgeon, and it can significantly reduce the occurrence of diseases in the artificial breeding process of sturgeon, especially the occurrence of bacterial sepsis, bacterial hemorrhagic disease and bacterial enteritis. Occurs, the survival rate increases by 13-16%, promotes the growth of sturgeon, and can improve the quality of sturgeon. Moreover, the price of raw materials used in the present invention is relatively low, and the production and use costs are relatively low, which is beneficial to cost saving.

Description

technical field

[0001] The invention belongs to the field of feed, and mainly relates to feed for aquaculture, in particular to a special compound feed for sturgeon breeding and a preparation method thereof. Background technique

[0002] Sturgeon is cartilaginous scale fish. Its meat is delicious and nutritious (rich in brain gold and B vitamins). It is highly praised by gourmets. Known as “gold”, the foreign sturgeon fishery is currently one of the most profitable industries in the world. In recent years, with the development of human society, the establishment of hydropower stations in rivers and lakes and the construction of ship locks have seriously affected the self-foraging channels of sturgeons, causing rare and special aquatic products such as sturgeons to be on the verge of extinction. Since April 1, 1998 , the United Nations Convention on Washington (CITIS) recognizes wild sturgeons all over the world as endangered protected animals. Sturgeons in my country are m...
