Problems solved by technology

[0003] With the rapid development of the shrimp farming industry in recent years, on the one hand, the high-density farming has caused the deterioration of the farming environment and frequent occurrence of diseases; Homeostasis of Gut Microbiota of Penaeus prawns
Therefore, the conventional compound feed for Litopenaeus vannamei not only cannot prevent the phenomenon of "white stool", "red legs" and "rotten gills" in the breeding process, but also cannot meet the nutritional needs of high-density breeding

Embodiment 1

[0047] A functional feed for Litopenaeus vannamei, comprising the following raw materials in parts by weight: 17 parts of flour, 2.8 parts of Jiatikang, 24.5 parts of fish meal, 2.4 parts of shrimp shell powder, 4.7 parts of chicken meal, and 4.7 parts of hydrolyzed yeast powder , 2.3 parts of hemoglobulin powder, 12.2 parts of soybean meal, 9.4 parts of peanut meal, 5.6 parts of rapeseed meal, 4.7 parts of squid paste, 1.9 parts of calcium dihydrogen phosphate, 0.9 parts of fish oil, 0 parts of AB bacteria powder, 0 parts of Clostridium butyricum 2.8 parts of compound premix, 0.1 part of vitamin C, and 3.8 parts of lecithin.

[0048] Specifically, the Jiatikang is a mixed fermented material, and the fermentation strain is: Saccharomyces cerevisiae (the number of live yeast in the bacterial powder is ≥2.0×10 10 individual / g), Bacillus subtilis (effective spore content ≥ 2.0×10 10 individual / g) and Aspergillus oryzae (effective spore content≥2.0×10 9 per g), the addition rati...

Embodiment 2

[0058] A functional feed for Litopenaeus vannamei, comprising the following raw materials in parts by weight: 17 parts of flour, 2.8 parts of Jiatikang, 24.5 parts of fish meal, 2.4 parts of shrimp shell powder, 4.7 parts of chicken meal, and 4.7 parts of hydrolyzed yeast powder , 2.3 parts of hemoglobulin powder, 12.2 parts of soybean meal, 9.4 parts of peanut meal, 5.6 parts of rapeseed meal, 4.7 parts of squid paste, 1.9 parts of calcium dihydrogen phosphate, 0.9 parts of fish oil, 0.24 parts of AB bacteria powder, 0.02 parts of Clostridium butyricum 2.8 parts of compound premix, 0.1 part of vitamin C, and 3.8 parts of lecithin.

[0059] In the functional feed of Litopenaeus vannamei, the mass fraction of crude protein is 40.91%, and the mass fraction of crude fat is 7.49%.

[0060] The preparation method is the same as in Example 1.

Embodiment 3

[0062] A functional feed for Litopenaeus vannamei, comprising the following raw materials in parts by weight: 17 parts of flour, 2.8 parts of Jiatikang, 24.5 parts of fish meal, 2.4 parts of shrimp shell powder, 4.7 parts of chicken meal, and 4.7 parts of hydrolyzed yeast powder , 2.3 parts of hemoglobulin powder, 12.2 parts of soybean meal, 9.4 parts of peanut meal, 5.6 parts of rapeseed meal, 4.7 parts of squid paste, 1.9 parts of calcium dihydrogen phosphate, 0.9 parts of fish oil, 0.48 parts of AB bacteria powder, 0.04 parts of Clostridium butyricum 2.8 parts of compound premix, 0.1 part of vitamin C, and 3.8 parts of lecithin.

[0063] In the functional feed of Litopenaeus vannamei, the mass fraction of crude protein is 41.01%, and the mass fraction of crude fat is 7.50%.

[0064] The preparation method is the same as in Example 1.

Abstract

The invention relates to a functional feed for litopenaeus vannamei and a preparation method of the functional feed for the litopenaeus vannamei. Comprising the following raw materials in parts by weight: 15-20 parts of flour, 0.01-3 parts of jaboticin, 20-25 parts of fish meal, 1-3 parts of shrimp shell meal, 3-6 parts of chicken meal, 3-6 parts of hydrolyzed yeast, 1-3 parts of spray-dried animal blood cells, 10-15 parts of soybean meal, 7-12 parts of peanut meal, 4-10 parts of rapeseed meal, 3-10 parts of squid paste, 1-2.5 parts of monocalcium phosphate, 0.1-1.5 parts of fish oil, 0.01-1 part of AB bacteria, 0.01-0.1 part of clostridium butyricum, 1-5 parts of a compound premix, 0.01-3 parts of vitamin C and 2-6 parts of lecithin. The functional feed for the litopenaeus vannamei can promote healthy growth of the litopenaeus vannamei, improve immunity of the litopenaeus vannamei, maintain intestinal health and effectively prevent and treat the phenomena of white feces, red legs, gill rot and the like in the culture process, so that the survival rate and yield of the litopenaeus vannamei are improved.

Description

technical field [0001] The invention relates to the technical field of aquatic feed, in particular to a functional feed for Litopenaeus vannamei and a preparation method thereof. Background technique [0002] Litopenaeus vannamei, also known as Penaeus vannamei, has become one of the important aquaculture species in my country because of its advantages of fast growth, high nutritional value, wide adaptability to salinity, and high reporting rate. [0003] In recent years, with the rapid development of the shrimp farming industry, on the one hand, the high-density farming has caused the deterioration of the farming environment and frequent occurrence of diseases; Homeostasis of the gut microbiota of Penaeus prawns. Therefore, the conventional compound feed for Litopenaeus vannamei not only cannot prevent the phenomenon of "white stool", "red legs" and "rotten gills" in the breeding process, but also cannot meet the nutritional needs of high-density breeding.
