Description

[Affiliated technical field]

[0001] The invention relates to a compound feed for Litopenaeus vannamei and belongs to the field of chemical composition inventions. [Background technique]

[0002] At present, the compound feed for prawns first considers the nutritional needs of the growth of prawns, such as Chinese patent CN1042292; The above-mentioned prawn compound feeds have not considered the influence of feed formula and additives on the quality of cultured prawns. Compared with wild prawns living in nature, the quality of artificially cultured Litopenaeus vannamei is poor, manifested in: light skin color, reduced crude protein content in muscle, three indicators of essential amino acid ratio in protein, essential amino acid index, and protein The nutrients are low, but the fat content is higher than that of wild prawns. At the same time, artificially cultured prawns taste bad, while wild prawns in nature are more delicious. This situation is related to the use of feed...
