What factors cause increased mortality and slow-growing piglets in the nursery phase? How can we address these issues?
How and when should I use controlled oral exposure? What are the risks?
In the first article of this series, the four specialists shared with us about the increase in neonatal diarrhea problems and explained which were the main causative agents according to their experience. In this article, we will address preventive strategies using vaccination methods.
What nutrients can we increase or decrease in piglet diets during lactation and after weaning to improve immune response and growth?
Changes on the source of replacement animals are always difficult decisions. Monitoring through testing before the introduction of the new animals into the farm is not sufficient.
List of practical measures applied in our daily work with good results. Those measures must be considered as a whole and never individually.
We were called for clinical problems on weaners that appeared a few days after a feed transition in a farrow-to-finish farm: swelling of the eyelids and forehead, incoordination, dyspnea and sudden death.
This case study describes an outbreak in a commercial unit which proved difficult to stop without vaccine. Since 2014 an increasing number of cases of this disease have been reported in Europe though it remains unclear why it has reappeared.
To diagnose E. coli scours we must rule out all other causative agents of early nursery scours, including TGE, PEDv, PDCoV, Rotavirus, and Salmonellosis, and get a positive E. coli culture from piglet rectal swabs.
How can we expect our livestock to acquire a healthy microbiome when there is such limited exposure to the microbes that they evolved with?
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.
Diarrhoea is their most typical clinical manifestation, and the earlier the onset, the more harmful it is. Newborn piglets can present with another clinical picture, with signs of sepsis (shock, depression, death, polyarthritis), which is associated with an extraintestinal E. coli.
The article provides an alternative to the current vaccination programs that could be the solution for farms with early onset oedema disease. However, this alternative —consisting of vaccinating the dams at the end of gestation to achieve post-weaning piglets immunization—, also raises questions...
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.
