Problems solved by technology

In the southern Jiangsu market, due to the low water temperature from March to April and the slow growth of fish species, the feed manufacturers at this time mostly use cotton meal and rapeseed meal as the main formula structure, and the amount of high-quality animal raw materials such as fish meal is very small. The formula structure is also not conducive to the recovery of the physique of the group head bream

The mixed feed disclosed by the invention can be used for effectively improving the functions of liver and gall and the immunocompetence and promoting breeding development.

Description

Technical field [0001] The present invention relates to a compound feed, in particular to a feed for bream bream species after overwintering and a preparation method thereof. Background technique [0002] Group head bream, belonging to the order Cypriformes, Cyprinidae, subfamily, bream, commonly known as Wuchang fish, is one of the important herbivorous economic fishes in my country, because of its wide feeding habits, high survival rate, fast growth, and excellent meat quality. The delicious taste and other advantages are deeply favored by farmers and consumers. [0003] The southern Jiangsu area is one of the main breeding areas for bream bream in my country. The model of bream bream seedlings in this area is as follows: each year, the fry will be purchased and fed until the end of November. At this time, the size of the fish species is 7- 15 fish per catty, stop feeding when the water temperature is lower than 12 degrees from December to early March of the following year, and do...
