Embodiment 1

[0017] A special feed for Penaeus vannamei during liver transition, including the following components by weight percentage, fish meal 22.2%, soybean meal 35%, cod liver oil 2%, corn meal 28%, blood meal 4%, lecithin oil 2%, vitamin C 0.2 %, multi-dimensional premix for shrimp 0.58%, multi-mineral premix for shrimp 3%, methionine-lysine complex for shrimp 0.5%, compound microorganism 1%, antioxidant 0.02%, thiobetaine 1%, Binder 0.5%. Among them, the composite microorganism is Lactobacillus acidophilus and the content is 5×10 7 cfu / g, the bifidobacterium content is 2.0×10 6 cfu / g, the brewer's yeast 6.0×10 8 cfu / g. The adhesive is prepared by mixing kelp powder and fish alginate in a mass ratio of 3:1.

Embodiment 2

[0019] A special feed for Penaeus vannamei during liver transition, including the following components by weight percentage, fish meal 23.1%, soybean meal 38%, cod liver oil 1%, corn meal 26%, blood meal 2%, lecithin oil 3%, vitamin C 0.4 %, multi-dimensional premix for shrimp 0.6%, multi-mineral premix for shrimp 2.5%, methionine-lysine complex for shrimp 0.38%, compound microorganism 1.5%, antioxidant 0.02%, thiobetaine 1%, Binder 0.5%. Among them, the composite microorganism is Lactobacillus acidophilus and the content is 5×10 7 cfu / g, the bifidobacterium content is 2.0×10 6 cfu / g, the brewer's yeast 6.0×10 8 cfu / g. The adhesive is prepared by mixing kelp powder and fish alginate in a mass ratio of 3:1.

Abstract

The invention relates to the feed field, particular to special feed for penaeus vannamei in a liver transformation period. The feed is prepared from components in percentage by weight as follows: 23%-26% of fish meal, 27%-40% of soybean meal, 1%-2% of cod liver oil, 20%-30% of corn starch, 2%-4% of blood powder, 2%-3% of lecithin oil, 0.2%-0.4% of vitamin C, 0.4%-1% of a multi-vitamin premix for shrimps, 2%-4% of a multi-mineral premix for shrimps, 0.3%-0.5% of a methionine-lysine compound, 1%-1.5% of complex microorganisms, 0.02%-0.06% of an antioxidant, 0.5%-1% of dimethylpropiothetin and 0.2%-0.5% of an adhesive. The nutrients in the feed are reasonably proportioned and the complex microorganisms are added to the feed. The complex microorganisms help penaeus vannamei to digest and absorb the feed, reduce pollutants in water, increase supply of carbon sources in water and inhibit and hinder attachment and reproduction of pathogenic bacteria in digestive tracts. The immunity of the penaeus vannamei is improved, the penaeus vannamei can be promoted to quickly pass away the liver transformation period, and the survival rate is greatly increased.

Description

technical field [0001] The invention relates to the field of feed, in particular to a special feed for Penaeus vannamei during liver transformation. Background technique [0002] Generally, after 18 to 22 days of shrimp culture, the hepatopancreas will be in a rapid development period: at this time, when observing the prawns with the naked eye, you will find that a layer of white film gradually covers the hepatopancreas, and the black and white gradually become clear, forming an outline. People in the industry generally call this The rapid development period is the transition period. Penaeus vannamei is released for 30 days, which coincides with the stage of liver transfer of shrimp seedlings. Due to the change of diet, frequent molting, and incomplete development of liver and other organs, it belongs to the peak period of the disease. If during this period, environmental mutations (such as weather changes) , wind direction change, large temperature difference between cold ...
