Problems solved by technology

[0002] With the rapid development of my country's aquaculture industry in the past ten years, animal diseases have also spread rapidly, causing huge damage to my country's aquaculture industry. Antibiotics play an active role in the prevention and control of epidemic diseases. However, long-term use of antibiotics will cause animal diseases. The drug resistance of pathogenic microorganisms is increasing continuously. At the same time, the large-scale use of antibiotics has led to a large number of antibiotic residues in livestock products, which poses a serious hazard to human health. The call for restricting the use of antibiotics in the breeding process is increasing

Embodiment 1

[0038] The aloe polysaccharide feed in this example includes concentrate and forage in a weight ratio of 30:40. Among them, the concentrate includes aloe polysaccharide and enzyme with a weight ratio of 10:8. The forage is alfalfa grass.

[0039] The above-mentioned aloe polysaccharides were obtained by the following treatment: first extracting Aloe vera with water at a weight ratio of 50:1 at 70° C. for 4 hours, and filtering to remove water-soluble substances to obtain a filter residue. Then dissolve the filter residue with citric acid solution, extract for the second time at 100°C for 5 hours, filter, and collect the filtrate. Adjust the pH of the filtrate to 6.5, add ethanol solution, and stand at 5° C. for 2 hours to denature and separate the aloe polysaccharides, filter and collect the precipitate to obtain aloe polysaccharides.

[0040] The enzyme is obtained through the following treatment: ferment blueberry, white sugar and bifidobacteria at a weight ratio of 40:10:...

Embodiment 2

[0043] The aloe polysaccharide feed in this embodiment is a pellet feed with a length of 4 cm. The aloe polysaccharide feed includes concentrate and forage with a weight ratio of 50:60. Among them, the concentrate includes aloe polysaccharides, enzymes, traditional Chinese medicine preparations and malt with a weight ratio of 15:12:35:5. The forage is alfalfa grass and milk vetch.

[0044] The above-mentioned aloe polysaccharides were obtained by the following treatment: first extracting Aloe vera with water at a weight ratio of 60:1.5 at 90° C. for 3 hours, filtering to remove water-soluble substances, and obtaining a filter residue. Then the filter residue was dissolved with malic acid solution, extracted for the second time at 105° C. for 3 h, filtered, and the filtrate was collected. Adjust the pH of the filtrate to 7.5, add ethanol solution, and stand at 10° C. for 4 hours to denature and separate the aloe polysaccharide, filter, collect the precipitate, and obtain the ...

Embodiment 3

[0049] The aloe polysaccharide feed in this example is a pellet feed with a length of 6 cm. The aloe polysaccharide feed includes concentrate and forage in a weight ratio of 40:50. Among them, the concentrate includes aloe polysaccharides, enzymes, traditional Chinese medicine preparations and malt with a weight ratio of 10:8:16:3. Forage is alfalfa grass and rye grass.

[0050] The above-mentioned aloe polysaccharides were obtained by the following treatment: firstly extracting Aloe vera with water at a weight ratio of 55:1.25 at 80° C. for 3.5 hours, and filtering to remove water-soluble substances to obtain a filter residue. Then the filter residue was dissolved with malic acid solution, extracted for the second time at 102.5°C for 4 hours, filtered, and the filtrate was collected. Adjust the pH of the filtrate to 7, add ethanol solution, and stand at 7.5°C for 3 hours to denature and separate the aloe polysaccharides, filter and collect the precipitate to obtain aloe pol...

Abstract

The invention relates to an aloe polysaccharide feed and an antibiotic-free breeding method for Miaozhai pigs, and belongs to the field of breeding. The aloe polysaccharide feed comprises a concentrate and a fodder according to a weight ratio of 30-50:40-60, wherein the concentrate comprises aloe polysaccharide and enzyme according to a ratio of 10-15:8-12, and the fodder comprises any one selected from medicago sativa, astragalus sinicus l, lolium perenne l, rosinweed, amaranthus hypochondriacus l and cichorium intybus l. According to the present invention, the aloe polysaccharide feed does not contain antibiotics, uses the aloe polysaccharide and the enzyme to replace commonly used antibiotics, and can improve the immunity and the growth potential of pig; the breeding method is feeding Miaozhai pigs with the aloe polysaccharide feed, wherein the feeding amount of the aloe polysaccharide feed is 8-15% of the body weight of the Miaozhai pig; and the method is simple, the breeding cost is low, and the bred Miaozhai pig grows well.

Description

technical field [0001] The invention relates to the field of breeding, and in particular to an aloe polysaccharide feed and an antibiotic-free breeding method for Miao village pigs. Background technique [0002] With the rapid development of my country's aquaculture industry in the past ten years, animal diseases have also spread rapidly, causing huge damage to my country's aquaculture industry. Antibiotics play an active role in the prevention and control of epidemic diseases. However, long-term use of antibiotics will cause animal diseases. The drug resistance of pathogenic microorganisms is increasing continuously. At the same time, the extensive use of antibiotics has resulted in a large number of antibiotic residues in livestock products, which poses a serious hazard to human health. The call for restricting the use of antibiotics in the breeding process is increasing. The European Union has banned the addition of antibiotics in feed since January 2006, and fully impleme...
