Embodiment 1

[0043] Preparation of Enteromorpha polysaccharide: prepared by the following steps:

[0044] (1) Fresh Enteromorpha, clean and dry;

[0045] (2) Grind Enteromorpha to powder, add water according to the material-to-liquid ratio 100g:400ml, boil at 100℃ for 3h, repeat 3 times;

[0046] (3) Combine the three times of filtrate concentration, add 3 times the amount of 95% ethanol 4000r / min, centrifuge for 30min, and obtain the precipitate;

[0047] (4) The precipitate is washed with acetone and ether to remove fat, and the solid is dried to obtain Enteromorpha polysaccharide.

Abstract

The invention relates to a feed additive and especially relates to a livestock and poultry feed additive as well as a preparation method and an application thereof. The livestock and poultry feed additive comprises the following ingredients in parts by weight: 70-80 parts of enteromorpha polysaccharide, 2-4 parts of ganoderma lucidum polysaccharide, 5-8 parts of Chinese scholartree flower polysaccharide, 2-5 parts of herba houttuyniae polysaccharide and 5-7 parts of honeysuckle flower polysaccharide. According to the invention, a solid preparation prepared from the enteromorpha polysaccharide, the ganoderma lucidum polysaccharide, the Chinese scholartree flower polysaccharide, the herba houttuyniae polysaccharide and the honeysuckle flower polysaccharide is used as the feed additive; and the feed additive is capable of obviously promoting animal production performance and improving animal immunity.

Description

Technical field [0001] The invention relates to a feed additive, in particular to a livestock and poultry feed additive, a preparation method and application thereof. Background technique [0002] At present, a large number of ingredients such as antibiotics and hormones are used as feed additives in livestock and poultry feeds. Long-term use of such feed additives brings many disadvantages, such as causing intestinal flora imbalance, increasing drug-resistant strains, decreasing immune function, and drug residues in livestock products. Seriously exceeding the standards, etc., so that livestock and poultry products are seriously polluted. Therefore, natural, low-toxic, and green feed additives without drug residues have become a subject of much concern in the field of veterinary medicine. Enteromorpha is a genus in the Ulva family of the Chlorophyta. There are about 40 species in the world and about 11 species in China. Enteromorpha polysaccharides are the key active ingredients...
