Porcine Health Management

Influenza A virus (IAV) subtypes H1N1, H1N2 and H3N2 circulate in swine herds in Belgium. Shortly after the emergence of the human pandemic H1N1 2009 IAV (pdmH1N1(2009)), variants of this strain occurred in global swine populations. Here we describe the...

Intensive pig husbandry offers optimum transmission conditions for pathogens. Especially undetected influenza A virus (IAV) infections cause immense financial losses in pig production and poses a risk to human health. Correlation of clinical signs and...

PRRSV is still one of the most important viruses in the global swine industry and is often controlled by the use of modified live virus (MLV) vaccines in sows and piglets. Recently, a novel MLV for active immunization of clinically healthy piglets from...

PRRS to control in the modern swine industry. The clinical impact has not declined since the appearance in the early 90’s. More and more countries are working on control or even eradication of the virus. Hungary started in 2014 with a national PRRS...

PRRS control remains a challenge and needs a whole herd approach to be successful. The aim of this study was to evaluate the benefit of the “5-step” process, which has been developed by Boehriger Ingeheim (BI), to control PRRS in 6 French FF herds.

Porcine reproductive and respiratory syndrome virus (PRRSV) infection is characterised by respiratory lesions, viral replication in alveolar macrophages and lymphoid organs and a strong early local inflammatory response together with a loss of the global...

The impact of dental and periodontal disease (DPD) on health and welfare of pigs is poorly understood. DPD may cause significant and long-lasting pain and infectious disease in other parts of the body. This study describes DPD in involuntarily culled...

The spread of an infectious disease within the livestock population is highly determined by the network of contacts between farms. Usually, a small fraction of the population contributes disproportionately to spread the infection and therefore targeted...

Swine influenza (swIAV) is a highly contagious respiratory infection with substantial economic consequences due to medication costs, pigs’ growth retardation and decrease of reproductive performance in affected sow herds.The objective of this study was...

The use of processing fluids is a sensitive tool to monitorize PRRSV status in a cost-effective way. The use of removed parts of carcasses could be a used as an aggregated sample to evaluate the presence of PRRSV. The main objective of this study is to...

Worm infections in pigs have an enormous impact on the average daily weight gain, feed conversion and mortality rate, if not well controlled. Ascaris suum is the most important endoparasite worldwide. The larval migration enhances respiratory and enteric...

The extent of carry-over and the following risk of cross-contamination of medicated premixes depend on the feed mill installation and the product features, such as the formulation and the active. The dust content of a premix is closely correlated with...

Microbiota not only play a role in diseased animals but also influence production results in healthy animals. Our study investigated the association between fecal microbiota, fecal nutrient digestibility and performance traits in healthy commercial...

Mastitis is expected to be prevalent in sows with postpartum dysgalactia syndrome (PDS) - mainly due to Escherichia coli (E. coli), whose cell membrane contains lipopolysaccharides (LPS) that can induce inflammation. This study investigated LPS in the...

Postpartum dysgalactia syndrome (PDS) in sows may be due to disturbances in hormonal and metabolic processes or oxidative stress during the periparturient period. Further, PDS is difficult to diagnose. This study describes the changes of cortisol,...
