A picture is worth a thousand words (or more!) when it comes to farm biosecurity
Three videos that illustrate how to make an appropriate transition between several key clean and dirty zones.


Three videos that illustrate how to make an appropriate transition between several key clean and dirty zones.

Let's clarify what are the clean and dirty zones and its boundaries. A series of articles will discuss how to apply segregation principles to farm zones for the prevention of pathogen entry.

Traditional gilt exposure to seeder animals is being substituted by intratracheal inoculation and aerosol exposure.

How can we promote a healthier microbiota, favorable for the pig and for its productivity? And, when is the best time to get it?

More than 50% of all systemic samples tested by HPS PCR at the Iowa State University Veterinary Diagnostic Laboratory (ISU VDL) are positive.

Some nutritional strategies can have an antibacterial activity, do you want to know which ones?

Do outbreaks in the same farm have a similar time-to-stability? What factors can affect time-to-stability?

Time flies and wild boar breed at a faster rate than our ability to control them.

Probiotics and amino acids to improve the intestinal barrier. Omega-3 fatty acids, plasma, probiotics, prebiotics, etc... to enhance the immune response.

The overgrowth of horn of the claw leading to slipper feet, cracking or separation, and secondary septic laminitis has a multifactorial origin.

When was the last time that you disinfected your cellphone?

71% of the farms reporting a PRRS break today will report a break within the following two years. What makes them more susceptible?

Pig reproduction and summer are not good friends, Heat comes, daylight hours drop, fertility decreases and the vets come across more reproductive pathology than during the rest of the year. Why doing always the same does not always yield the same result?

Compilation of nutritional strategies for the management of gut health, grouped by functional additives, functional ingredients and diet modifications.



How is it possible that a virus that causes an acute infection in an animal can remain on a farm throughout time?

The gut microbiome provides an alternative tool for control and prevention of diseases.

The author presents a review of the current situation of influenza in pigs to end with his doubts and comments on the effectiveness of control measures on the farm.

Can it be useful? How?

PCR can detect the virus in virtually any material but, does it mean the sample contains the virus and it is infectious? Is any PCR test valid for any strain?

Influenza researchers are trying to stimulate antibody responses towards parts of the HA that are the least variable from strain to strain. One approach that seems promising is choosing two antigenically very different strains within the H1 or H3 subtype for the primary and subsequent booster vaccinations.



Producing well with a low antimicrobial usage: Is it possible in high pig-density areas? And, what is the role of the age at weaning?

How can we monitor our program? Which pigs should be sampled? How many? How often should we sequence the virus/es present in our farms?

Could the vaccination against Salmonella in pigs be as crucial as it has been in poultry?

The farmer contacted the veterinary surgeon concerning an increase of respiratory distress and mortality in the finishing pigs during the previous 3 days.

Fernando Rodríguez, the director of CReSA, explains at what stage is the development of the vaccine against ASF.

In this third article, we want to to talk about a common guest in the nurseries: Streptococcus suis, the causative agent of clinical pictures that can include meningitis, arthritis and sudden deaths.
