Embodiment 1

[0046] Screening method for donor pigs and feces

[0047] Adult pigs over 300 days old (regardless of sex), the candidate individuals have no clinical symptoms of diarrhea and other major pig diseases. No antibiotics were used within 30 days before stool collection, and clear immunization / medication records were available. Screening method of donor pigs: using serology, antibody detection and other means, referring to GB / T22914-2008 "Control and Monitoring of SPF Pig Pathogens" to exclude common / severe infectious pathogens in pigs.

[0048] Table 1. Screening method for donor pigs

[0049]

[0050] Screening of donor feces: Refer to GB29921-2013 "Pathogen Limits in Food" standard for Salmonella, Listeria monocytogenes, Escherichia coli O157:H7, Staphylococcus aureus, Vibrio parahaemolyticus 5 detection of pathogenic bacteria.

[0051] Abnormal toxicity test: According to the general rule 1141 of the Pharmacopoeia of the People's Republic of China, abnormal toxicity test ...

Embodiment 2

[0054] The preparation steps of fecal bacteria freeze-dried powder are:

[0055] Obtaining the fecal suspension:

[0056] Add 1 part of fresh feces of healthy adult pigs to 9 parts of sterile saline at 4°C, shake and mix with a homogenizer; Centrifuge for 5 minutes, carefully collect the supernatant; centrifuge the collected supernatant at 4600 rpm for 15 minutes at 4°C, and pour off the supernatant; the precipitate collected by centrifugation is in a 1:1 ratio, and again Add sterile physiological saline at 4°C, centrifuge at 4,600 rpm for 15 minutes at 4°C, and pour off the supernatant to obtain the final stool suspension.

[0057] Fecal bacteria concentration = (wet fecal weight / final fecal suspension volume) × 100% (unit: g / mL)

[0058] Addition of protective agent:

[0059] Add 10% sterilized glycerol (V / V) by volume to the final stool suspension, mix well and store at -80°C, add 10% sterilized skim milk equal to the volume of the final stool suspension , and then add ...

Embodiment 3

[0063] The stability test of the feces bacterium freeze-dried powder preparation of embodiment 2

[0064] After the freeze-dried powder of fecal bacteria was sealed at room temperature and stored in the dark for 0 month and 3 months, samples were taken to detect the contents of Bacillus, Lactobacillus, Lactobacillus, Bifidobacterium and Streptococcus thermophilus in the powder. Bacillus was detected by LB plate dilution coating method. Lactobacillus, Lactobacillus, Bifidobacterium and Streptococcus thermophilus were detected by the national standard GB4789.35-2010 method. 5 batches were randomly selected, and the average value of the test results was calculated. The results are shown in Table 2:

[0065] Table 2

[0066]

[0067] Conclusion: After the fecal bacteria freeze-dried powder prepared in Example 2 was stored at room temperature and protected from light for 3 months, the number of viable bacteria remained at 10 7 More than CFU / g, it shows that the present invent...

Abstract

The invention provides a coprophilous fungus composition. According to the invention, fresh night soil of adult health pig is taken as a manure source, a coprophilous fungus final suspension is prepared by three-time centrifugation under specific low-temperature condition, a high molecular weight compound protective agent skimmed milk powder and a low molecular weight compound protective agent (glycerin, lactose, galactose, cane sugar, glucose, maltodextrin, sorbitol, adonitol and trehalose) are added, the coprophilous fungus composition is produced, which contains abundant Bacillus spp, lactic acid bacteria, lactobacillus, bifidobacteria, and streptococcus thermophilus, live bacteria number is kept at 108 CFU / g and more, the coprophilous fungus composition is used for preventing and treating diarrhoea of pigling at a lactation period, the prevention and treatment effects are obvious, the coprophilous fungus composition has more obvious effect for preventing and treating diarrhoea of pigling with 0-14 days (21-28 days early-stage weaning method) and 0-21 days (35 days weaning method). The preparation method of the coprophilous fungus composition is simple, the product shelf-life is long, the defect that the current coprophilous fungus transplant requires real-time preparation in the prior art, and the coprophilous fungus composition is suitable for industrial production.

Description

technical field [0001] The invention relates to piglet breeding, in particular to a fecal bacteria composition for reducing diarrhea in lactating piglets, a preparation method and application thereof. Background technique [0002] The intestinal tract is the immune organ with the largest contact area between animals and the external environment. It is a complex internal environment composed of food residues and decomposition products, enzymes, immunoglobulins, bacteria (symbiotic and pathogenic bacteria) and metabolites, viruses, etc. When each The balance of ingredients is broken, and the body is in an unhealthy state. Studies have shown that whether it is virus, bacteria, protozoa or animal's own function, feed and feeding management, environmental stress, drug-induced diarrhea in pigs, the time of diarrhea responds to the imbalance of intestinal flora; such as porcine epidemic diarrhea, toxic Escherichia coli K88 infection and the occurrence of neonatal diarrhea syndrome...
