Early establishment of normal healthy functional flora in the gut of newborn piglets

Abstract

The invention discloses a method for forming normal healthy functional bacterial flora in intestinal tracts of newborn piglets in the early period. The method includes the steps of preparation of a primary birth canal bacterial liquid, preparation of a birth canal bacterial liquid for inoculation, grafting of birth canal bacterial flora into the newborn piglets, preparation of a primary coprophilous bacterial liquid, preparation of an intestinal bacterial liquid for inoculation and grafting of the intestinal bacterial liquid into the newborn piglets. According to the method, a normal healthy micro-ecological environment of the intestinal tracts of the newborn piglets can be created quickly, the growth of immune systems of the newborn piglets is stimulated, diarrhea can be effectively prevented from happening to the piglets, and the incidence rate of diarrhea of the piglets can be controlled within 3%; growth and reproduction of pathogenic microorganisms in the intestinal tracts can beeffectively suppressed, and diarrhea of the piglets is efficiently and thoroughly prevented and treated. Meanwhile, the normal healthy bacterial flora formed in the intestinal tracts in the early period can promote the growth and development of the newborn intestinal tracts, facilitate function exertion and shorten a suckling period, the weaning age of the newborn piglets can be changed to 21 daysold or even earlier from 28 days old, and weaning of the piglets in the early period can be achieved.

Description

technical field [0001] The invention relates to the technical field of animal husbandry and veterinary medicine, in particular to a method for early establishment of normal healthy functional flora in the intestinal tract of newborn piglets. Background technique [0002] There are a large number of microorganisms in the intestinal tract of piglets, including bacteria and eukaryotic microorganisms, among which the number of bacteria is as high as more than one thousand, mainly anaerobic bacteria. According to previous studies, Gram-positive bacteria with low GC content in pig intestines accounted for about 81%, mainly Firmicutes, Eubacteria and relatives, Clostridium, Bacillus, Lactobacillus and Streptococcus belongs to. Gram-negative bacteria accounted for about 11.2%, mainly Bacteroidetes and Cellulophages. Among them, Bacteroidetes and Firmicutes accounted for more than 90% of pig intestinal bacteria. The dynamic balance of intestinal microorganisms is a sign of animal ...

Problems solved by technology

However, there is no ideal method for gut establishment in neonatal animals

In particular, there is still no uniform standard for the selection and screening of donors for flora transplantation, and there are even many controversies. The effects of donor age, health evaluation, immune rejection and safety of flora still need long-term in-depth discussions.

[0004] The traditional intestinal flora establishment technology often starts after one month or four weeks of age, and the method of adding feed is often used, and the added probiotics are relatively simple; or the method of fecal bacteria transplantation is used, but the operation is complicated, the efficiency is low, and the influencing factors Many, susceptible to pathogen attack or stress response
