Hans Nauwynck defines himself as a veterinary virologist, a person who works in a laboratory setting, doing precise work, like a surgeon, aiming to gain a better understanding of how animal viruses interact with their target cells. But it is much more. His deep understanding of the biological behavior of viruses allows him to fluently explain many of the “whys” that are so important for a better understading of the pathogenesis of viral diseases and the development of effective control strategies.

Fewer losses, lower medication costs, and a better feed conversion ratio result in a 100% ROI on this depopulation-repopulation project.

We analyze the two most relevant respiratory viruses in the swine population.

Aerosol models may open a new range of possibilities for addressing knowledge gaps concerning M. hyopneumoniae infection and disease, treatment, and control.

Histopathology can provide a strong framework to establish the real causality of a clinical problem.

Breaking the chain of infection from humans to pigs and from pigs to humans.

We are launching a series of articles that will delve into a new practice that has already been implemented on several farms in Spain and is being adopted by others: 5-week batches.

One percentage of affected lung volume was associated with a 0.24% reduction in lean meat content.

We focus on moving surplus piglets, which forces us to use nurse sows. We explain two ways to do this in a very visual video.

Detection of lung lesions in slaughtered pigs also allows estimation of economic losses.

What laboratory diagnostic methods can I use to APP? Which one should I choose according to the situation? How do I interpret the results?

Here are three basic rules for deciding if and when to do cross fostering and use nurse sows.

Depending on the levels of maternal derived immunity, a potential interference of vaccine intake may happen, jeopardizing vaccine seroconversion and efficacy.

Collecting data at the slaughterhouse is a common method to obtain information on health and productive parameters, mainly from the last weeks of a pig’s life.

This article presents the main characteristics of the vaccines that can be found on the market.

Farrowing induction is needed to improve the ability of farm staff to supervise farrowing, but you need to be strategic; do not induce unless evidence says it is needed.

We conclude this two-part series by Professor Pejsak by examining how immune stress affects the pig's body, gut, and production.

What exactly goes on in a pig's body when exposed to acute or chronic stress? What implications does stress have on production? Professor Pejsak draws on decades of research to answer to explain.

Identifying the different stages of farrowing allows us to monitor the process and take measures to maximize the number of piglets born alive and their viability.

In this second article Antonio Vela, Francisco José Pallarés, and David Espigares answer questions about the diagnosis, monitoring, and eradication of pleuropneumonia caused by Actinobacillus pleuropneumoniae (App).

We asked Antonio Vela, Francisco José Pallarés, and David Espigares about pleuropneumonia caused by Actinobacillus pleuropneumoniae (App). In this first article, we will talk about the evolution and control of the disease.

In this last article of the series, we discuss management strategies and the vaccines available to control swine influenza.

Understanding the farrowing process and recognizing the signs for the different stages of birth, help us to develop management plans to improve the likelihood for live born piglets.

This concludes our series of three articles with explanations from Alberto Garcia and Chretien Gielen about the measures to consider to reduce post-weaning diarrhea without the use of zinc oxide. We couldn't end without looking at key aspects such as the environment, water, and use of biologics.

The clinical picture associated with swine influenza is often complicated by temperature fluctuations, other viruses, or bacteria. In part two of this series, we look at the clinical signs of this disease.

The ban on the use of zinc oxide starting June 2022 makes it necessary to review and improve many aspects of weaning, especially in its early stages. With Alberto García and Chretien Gielen we address key management points for successful weaning without the use of zinc oxide.

We spoke with Alberto Garcia (Inga Food SA, Spain) and Chretien Gielen (De Varkenspraktijk, The Netherlands), to discuss aspects related to weaning management and conditions.

Currently, only the sperm-rich fraction is used. This article analyzes the possible use of the other fractions.

The influenza virus promotes colonization by secondary bacterial agents in the lung, facilitating their passage into the bloodstream.

Here's how ultrasound can be used to visualize ovarian structures, assess the state of puberty, and diagnose ovarian pathologies.
