Antimicrobial susceptibility of Finnish Brachyspira pilosicoli isolates

Brachyspira pilosicoli is the etiologic agent of porcine colonic spirochetosis, a diarrheal disease in growing pigs. Colitis associated with Brachyspira pilosicoli is less severe than swine dysentery caused by Brachyspira hyodysenteriae, however, antimicrobial therapy is needed on some farms to treat diarrhea in weaners and in young finishing pigs. According to principles of prudent use of antimicrobials, only effective drugs should be used.

An improved method of Streptococus suis serotyping and vaccine efficacy

Streptococcus suis is a gram positive bacterium that causes arthritis and fatal meningitis in young pigs. Currently, 35 different serotypes have been identified and serotype 2 is most commonly associated with the disease in the U.S. Serotyping results from isolates sent to diagnostic laboratories for testing are often non-typeable or ambiguous using current methods. In the present study, we used next generation sequencing to identify the serotype of several isolates.

Role of T cells in the immune-pathogenesis of porcine contagious pleuropneumonia

Porcine contagious pleuropneumonia caused by Actinobacillus pleuropneumoniae (APP) remains one of the major causes of poor growth performance in pig herds. After recovering from the acute phase, pigs often become carriers harbouring the pathogen in tonsils, nares and chronic lung lesions. While most of the literature focuses on the role of the humoral response in attenuating the occurrence of acute symptoms, the porcine T-cell response to APP has been poorly characterised so far.

Estimating the costs of Porcine Reproductive and Respiratory Syndrome (PRRS) at individual farm level using a tailor-made mathematical model

Porcine reproductive and respiratory syndrome (PRRS) is among the diseases with the highest economic impact in pig production worldwide. Losses due to the disease were estimated as high as 560 Mio. US$ per year in the USA. Yet, the economic impact of the disease at farm level is not well understood as, especially in pig herds chronically infected with PRRS virus, the losses caused are often not obvious for farmers and veterinarians

Effect of trimming long toes of sows on longevity, productivity, and economic return

Trimming long toes has become a topic of interest for improving sow retention and herd productivity. However, there is limited scientific evidence that trimming long toes in commercial sow farms results in improved productivity and therefore is economically justified. Therefore, the objective was to evaluate the effects of trimming long toes, overgrown heels and long dewclaws on sows and the impact this has on longevity and productivity to determine economic return.

Association between biosecurity, productivity and antimicrobial use in Danish pig herds

Biosecurity is a key element of good farming practice and considered important to prevent disease spread within and between pig herds. Increased prevalence of disease in a pig herd usually results in decreased productivity and increased use of antimicrobials. One prevention strategy is to increase the focus on biosecurity. However, how effective is this?

Why do neonatal piglets get diarrhoea?

Diarrhoea during the first week of life is a big concern in many Danish pig herds - not least since the suspected introduction of “New Neonatal Diarrhoea Syndrome.” The study investigates pathogens and management-factors associated with these problems.

The prevalence and trends of economically important production diseases in Northern Ireland

Abattoir surveillance data is an important tool for disease monitoring and the detection of animal welfare conditions. The Northern Ireland voluntary pig health scheme, co-ordinated by Pig Regen, has recorded the presence of macroscopic lesions detected in the pluck and on the skin of slaughter pigs since 2005.

Pathogenesis comparison and cross-protection efficacy of the U.S. PEDV prototype and SINDEL-variant strains in weaned pigs

Two strains (U.S. prototype [P] and S-INDEL-variant [V]) of PEDV are currently circulating in the U.S. Pathogenesis comparison of the two strains in 5-day-old pigs showed that the V-strain was less virulent than the P-strain. However, PEDV pathogenicity is age dependent. Also, understanding the cross-protection between two strains is imperative for PEDV vaccine development. In the current study, the pathogenesis difference and the cross-protection efficacy between the two U.S. PEDV strains were evaluated in weaned pigs.

Combined PCV2 and Mycoplasma hyopneumoniae piglet vaccination has a positive impact on fattener performance compared with M Hyo only in a PCV2 subclinically infected farm

Besides PMWS (Post Weaning Multi-systemic Syndrome) or PCVD-systemic disease, PCV2 is also involved in many subclinical infections. In addition, PCV2 and Mycoplasma hyopneumoniae (Mhyo) infection results in a negative effect on performance. PCV2 and Mhyo vaccinations are an efficient tool to reduce mortality, lesions, viremia and to improve growth.

Relationships between weight, head morphology-assessed IUGR status and survival in commercial piglet production

Production improvements in the global swine industry have been partly produced by increasing selection for hyperprolific sows, resulting in larger litter sizes while also increasing the variation in piglet birthweight. This has increased the number of small and/or undersized piglets, which have been exposed to differing degrees of intrauterine growth restriction (IUGR). Most IUGR piglets are classified as being of low birth weight, however, there is large variation in weight of both non-IUGR and IUGR piglets.

Herd level risk factors for stomach ulcers in finishing pigs

The influence of feed structure and pelleting on the development of gastric ulcers in pigs is well established. Some studies have shown a beneficial effect of access to straw on gastric health. However, the role of other factors, e.g. disease and stress, is not well understood. The aim of this study was to identify herd factors associated with a high prevalence of gastric ulcers in finishing pigs.

Virtual farrowing unit – increase piglet survival rate in a game-­based setting

Incorrect procedures performed by farm workers or veterinarians can be costly and may jeopardize animal welfare. In the education of both veterinary students and farm workers, practical training is sparse and hands-­‐on clinical skills can be difficult to  obtain. Game-­‐based virtual training facilities are interactive and require participation as well as student decisions.

Risk factors for the different causes of piglet neonatal mortality in French farms

Neonatal mortality is one of the main issues of concern for the pig industry worldwide, resulting in decreased sow performance and significant economic loss. Although the issue of neonatal mortality has been explored previously, the variability in methodology makes it difficult to reach general conclusions. The relative proportions of each cause of death need to be identified.

Associations between Ascaris suum infections and management practices

Ascaris suum infections remain an important threat to the pig industry. A number of studies have been done in the last years regarding diagnosis, treatment and control. The aim of this study was to investigate the prevalence of A. suum in Belgium and to identify associations with farm management practices.
