Flaky hatch feed for prawn seedlings

Abstract

The invention discloses a flaky hatch feed for prawn seedlings. The feed consists of the following components in percentage by mass: 10 to 50 percent of fish meal, 5 to 10 percent of chicken meal, 3 to 10 percent of egg powder, 3 to 10 percent of Saccharomyces cerevisiae, 10 to 30 percent of artemia, 5 to 10 percent of squid powder, 10 to 16 percent of flour, 1 to 3 percent of betaine, 1 to 5 percent of fish oil, 1 to 3 percent of soyabean lecithin, 1 to 3 percent of vitamin mixture, and 2 to 4 percent of mineral element mixture, wherein each kilogram of vitamin mixture consists of the following components: 30g of vitamin A, 32g of vitamin D, 60g of vitamin E, 34.5g of vitamin K, 30g of vitamin B1, 2g of vitamin B2, 60g of vitamin B6, 4.5g of vitamin B12, 20g of niacin, 20g of calcium pantothenate, 0.15g of biotin, 150g of inositol, 4g of folic acid, 275g of vitamin C, and 337.85g of corncob meal; and each kilogram of mineral element mixture consists of the following components: 20g of copper sulfate, 100g of ferrous sulfate, 35g of zinc sulfate, 11g of manganese sulfate, 0.55g of cobalt chloride, 0.55g of sodium selenite, 20g of monopotassium phosphate, 20g of monosodium phosphate, and 792.9g of zeolite powder. The feed can improve the growth performance and the survival rate of the prawn seedlings.

Description

Technical field: [0001] The invention relates to a prawn feed, in particular to a sheet-shaped prawn seed opening feed. Background technique: [0002] At present, the main species of Penaeus cultured in my country include Penaeus vannamei Boone, Penaeus monodon, Penaeus chinensis and Metapenaeus ensis. Distributed in coastal areas from south to north, the annual output is nearly 4 million tons, and the output value is nearly 150 billion. A complete industrial chain of seed cultivation, breeding, processing and export has been formed. In view of the fact that shrimp farming has become the main shrimp farming species in my country, and its scale is also expanding, the cultivation of shrimp seedlings has also become a key issue in the development of the industry. High-quality shrimp seedlings that are safe and healthy, with neat specifications and fast growth speed are the necessary guarantee for the development of the industry. The development stage of prawn seed has gone thr...

Problems solved by technology

[0003] At present, domestic prawn seed cultivation mainly relies on natural bait such as Artemia, which is expensive, cumbersome to operate, and is easy to pollute water quality. The nurturing of openings brings inconvenience

Some other feeds manufactured by existing technology cannot be selected according to the growth and physiological digestion characteristics of prawn seedlings, and the production process is also very easy to destroy nutrients, resulting in these feeds are not suitable for feeding shrimp larvae, and the utilization rate is not high. It is easy to pollute the water quality, which is not conducive to the large-scale production and cultivation of shrimp fry
