How can we expect our livestock to acquire a healthy microbiome when there is such limited exposure to the microbes that they evolved with?
Colibacillosis in swine production
This article explains how E. coli breaks the complex intestinal barrier mechanisms in a comprehensible way.
Achieving good levels of colostral immunity by vaccinating sows is the first step to prevent scours; subsequently, active pre or post-weaning immunization must be added to prevent post-weaning diarrhoea.
Oedema disease prevention has traditionally been accomplished through the administration of antibiotics or manipulation of gut microbiota through diet. However, in recent years, many vaccines have been developed to prevent clinical manifestation of the disease.
Genetic selection provides a powerful tool to improve and maintain gut health in industrial pig production, and may in the future become a more sustainable alternative to the currently massive need for antibiotics.
OD will normally appear after 1 or 2 weeks post-weaning and most likely associated to the presence of other risk factors.
In practice, and to have active-acquired antibodies ready at weaning, piglets should be immunised 10 days to 2 weeks before weaning.
