A kind of feed for young Penaeus vannamei and preparation method thereof

Abstract

The invention discloses a young litopenaeus vannamei feed. The young litopenaeus vannamei feed is prepared from the following raw materials in parts by weight: 55-75 parts of shrimp slices, 2-3 parts of wall-breaking yeast, 2-3 parts of rhodotorula benthica, 0.1-0.5 part of astaxanthin, 0.3-0.8 part of vitamin D3, 2-4 parts of soluble calcium salt, 3-5 parts of adhesive, 8-10 parts of disintegrating agent and 3-5 parts of moisture absorbent. The invention also discloses a preparation method of the young litopenaeus vannamei feed. The preparation method comprises the following steps: crushing the raw materials into 500-mesh particles by using a superfine powder crushing technology, then pelleting and forming the feed by using a pelleting and forming technology. The young litopenaeus vannamei feed is capable of fully meeting the nutritional requirements of the litopenaeus vannamei in the eclosion period, thereby greatly improving the survival rate of the litopenaeus vannamei; the enough particle size of the feed can be guaranteed, thereby facilitating transportation and storage of the feed.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a feed for young Penaeus vannamei and a preparation method thereof. Background technique [0002] Penaeus vannamei is one of the three largest shrimp species with the highest aquaculture production in the world today, and it is native to the Pacific coast of South America. The meat of Penaeus vannamei is delicious, the processed meat rate can be as high as 67%, the suitable temperature range is wide, it can grow at 18-32 ℃, and the salt range is also wide, and it can grow under the condition of salinity 1-40‰. desalinated cultured species. In terms of breeding, Penaeus vannamei has the advantages of large size, fast growth, low nutritional requirements, and strong disease resistance. It has strong adaptability to changes in water environment factors, low requirements for feed protein content, and long survival time out of water. The fine species of intensive high-yield farming has ...
