Abstract

The invention relates to a fish and shrimp compound feed, in particular to a tilapia and litopenaeus vannamei polyculture compound feed, and belongs to the fields of compound feeds and processing thereof. The fish and shrimp polyculture compound feed is prepared from the following raw materials in percentage by mass: 7 to 12 percent of directly heated fish meal, 15 to 30 percent of soybean meal, 15 to 30 percent of rapeseed meal, 1 to 2 percent of liquid phospholipid, 5 to 15 percent of wheat short, 15 to 30 percent of corn, 8 to 20 percent of strong flour, 0.5 to 1 percent of calcium dihydrogen phosphate, 0.05 to 0.1 percent of compound vitamin, 0.5 to 1 percent of compound mineral, 0.02 to 0.3 percent of immune potentiator and 0.5 to 1 percent of fish oil. The fish and shrimp polyculture compound feed has the advantages of low feed coefficient, promotion of the fast growth of the tilapia and the litopenaeus vannamei, difficulty in polluting culture water quality, low cost and the like.

Description

【Technical field】 [0001] The invention relates to a fish and shrimp compound feed, in particular to a mixed culture compound feed of tilapia and Litopenaeus vannamei, belonging to the field of compound feed and its processing. 【Background technique】 [0002] With the continuous expansion of the culture scale of Litopenaeus vannamei, the occurrence of its diseases has also caused serious economic losses. In order to reduce the morbidity probability of Litopenaeus vannamei and improve the breeding efficiency, someone has developed a culture technology of polyculture of tilapia and Litopenaeus vannamei (Chinese patent CN200910041547.5). Utilizing the omnivorous nature of tilapia, which eats both water plants and various organic debris, algae and aquatic insects, to clean the pond, the reasonable combination of tilapia and Litopenaeus vannamei makes the waste inside the breeding system Recycling and reuse of materials to achieve the best use of various resources. So far, the f...
