Problems solved by technology

Large-scale breeding leads to an increase in the density of fish pond animals, and the pressure on the prevention and control of disease infection increases
Antibiotics have made great contributions to aquatic animal diseases, but problems such as bacterial resistance and drug residues caused by the abuse of antibiotics have also emerged; in addition, the circulation of water resources in aquaculture has also led to the spread of drug resistance, making The spread of drug residues is difficult to control, and the resulting public health risks are becoming increasingly prominent

Embodiment 1

[0026] Embodiment 1 prepares premixed feed for aquatic animals

[0027] According to the mass percentage content, 4% xylooligosaccharide, 0.5% chitosan oligosaccharide, 0.5% phytosterol, 45% attapulgite, and 50% yeast extract are fully mixed to obtain the premixed feed , packed in a moisture-proof aluminum foil bag.

[0028] Said xylo-oligosaccharides are conventional xylo-oligosaccharides or ultra-finely pulverized xylo-oligosaccharides obtained through further processing by ultra-fine pulverization technology, and this embodiment is ultra-finely pulverized xylo-oligosaccharides. The chitosan oligosaccharide is the conventional chitosan oligosaccharide obtained through direct degradation of the oligosaccharide or the ultrafine pulverized chitosan oligosaccharide obtained by further processing through the ultrafine pulverization technology. Chitosan oligosaccharide. The phytosterols are pure phytosterols or emulsified phytosterols, and this embodiment is emulsified phytoster...

Embodiment 2

[0029] Embodiment 2 prepares premixed feed for aquatic animals

[0030] According to the mass percentage content, 5% xylooligosaccharide, 1% chitosan, 1% phytosterol, 58% attapulgite, and 35% yeast extract are fully mixed to obtain the premixed feed , packed in a moisture-proof aluminum foil bag.

[0031] The raw material requirements are the same as in Example 1.

Embodiment 3

[0032] Embodiment 3 prepares premixed feed for aquatic animals

[0033] According to the mass percentage content, 3% xylooligosaccharide, 1% chitosan, 1% phytosterol, 40% attapulgite, and 55% yeast extract are fully mixed to obtain the premixed feed , packed in a moisture-proof aluminum foil bag.

[0034] The raw material requirements are the same as in Example 1.

[0035] Effect test 1

[0036] In order to verify the application effect of the premixed feed prepared in Example 1, the animal effect test was carried out using the premixed feed product prepared in Example 1. Eriocheir sinensis is selected as the test object in the effect test of embodiment 1, and the test is divided into 3 groups, feeding the basal ration and adding the premixed feed group of Example 1 of different gradients (0.5% and 1%) in the basal ration respectively , 6 repetitions were set for each group, 12 rats for each repetition, the pre-test was 1 week, and the formal test was 8 weeks. As can be se...

Abstract

The invention discloses an aquatic animal premixed feed and a preparation method and applications thereof. The premixed feed comprises the following components in percentage by mass: 3-5% of xylo-oligosaccharide, 0.5-1.0% of chitosan oligosaccharide, 0.5-1.0% of phytosterol, 40-60% of attapulgite and 35-55% of yeast extract. The premixed feed is added into an aquatic animal feed according to a proportion of 0.5-2%, so that the organism immunity of aquatic animals can be enhanced, the intestinal tract health can be improved, and the organism growth performance can be improved.

Description

technical field [0001] The invention relates to the technical field of aquatic animal breeding, in particular to a premixed feed for aquatic animals and its preparation method and application. Background technique [0002] China is a big country in aquaculture. In 2016, the total global aquatic feed production was 39.9 million tons, and China's aquatic feed production reached 16.4 million tons, exceeding 1 / 3 of the global total. [0003] In recent years, with the technological and large-scale development of the aquaculture industry, the problems of aquaculture pollution prevention and disease prevention and control are the main factors restricting the development of aquaculture industry. Large-scale breeding has led to an increase in the density of fish pond animals, and the pressure on disease infection prevention and control has increased. Antibiotics have made great contributions to aquatic animal diseases, but problems such as bacterial resistance and drug residues cau...
