Problems solved by technology

The existing compound feeds for Litopenaeus vannamei do not consider the influence of feed formula on the growth performance and appearance quality of Litopenaeus vannamei cultured at low salinity
Compared with high-salinity cultured or wild Litopenaeus vannamei, the growth performance and quality of the current low-salinity cultured Litopenaeus vannamei are poor, mainly manifested in low growth performance, not fresh and sweet meat quality, high water content in the shrimp body, Shrimp body is not red enough after cooking

Abstract

The invention discloses a feed for litopenaeus vannamei boone, in particular to a composite feed for feeding litopenaeus vannamei boone cultured at low salinity, which comprises the following components in part by weight: 20 to 30 parts of manhattan fish meal, 10 to 16 parts of bean pulp, 10 to 14 parts of peanut cake, 7 to 10 parts of corn protein powder, 18 to 20.5 parts of high gluten flour, 1to 3 parts of molasses yeast, 1 to 3 parts of squid extract, 0 to 1 part of table salt, 1 to 2 parts of calcium lactate, 0 to 0.5 part of monocalcium phosphate, 1 to 2 parts of fish oil, 1 to 2 partsof soyabean lecithin, 1 part of vitamin premix and 1 part of mineral premix. The feed is mixed simply and balance in nutrition, can obviously improve the growth of the litopenaeus vannamei boone cultured at low salinity and improve the meat quality and color of the litopenaeus vannamei boone cultured at low salinity.

Description

【Technical field】 [0001] The invention relates to a feed for Litopenaeus vannamei, in particular to a compound feed which is suitable for cultivating Litopenaeus vannamei at low salinity and can improve the growth performance and meat quality of the Litopenaeus vannamei. 【Background technique】 [0002] At present, the compound feed of Litopenaeus vannamei is first considered to meet the nutritional needs of the growth of prawns, and there are also feed formulas that consider improving the anti-virus and immune capabilities of prawns. None of the existing compound feeds for Litopenaeus vannamei has considered the influence of feed formula on the growth performance and appearance quality of Litopenaeus vannamei cultured at low salinity. Compared with high-salinity cultured or wild Litopenaeus vannamei, the growth performance and quality of the current low-salinity cultured Litopenaeus vannamei are poor, mainly manifested in low growth performance, not fresh and sweet meat qual...
