Relationship between ovulation rate and litter characteristics at birth

The genetic selection for increased litter size has resulted in a disproportionate increase in ovulation rate (OR). A higher OR was linearly related with decreased placental length at day 35 of pregnancy, which could inhibit foetal growth during further pregnancy (Da Silva et al., 2016). As increased litter size has resulted in a decreased piglet birth weight and increased within litter birth weight variation, we investigated the relationship between OR and litter characteristics at term.

The relationship between antimicrobial use, antimicrobial resistance and health and biosecurity status in Canadian growfinish swine herds

Antimicrobial resistance (AMR) is a global threat to public health. The Canadian Integrated Program for Antimicrobial Resistance Surveillance (CIPARS) is a national integrated program dedicated to the collection, integration, analysis, and communication of trends in antimicrobial use (AMU) and AMR in selected bacteria from humans, animals, and food sources across Canada.

Impact of vaccination on the consumption of antimicrobials in Danish weaners, 2013

The development of antimicrobial resistance due to use of antimicrobials (AM) in livestock production is increasingly causing public concern. Vaccination might be an alternative to use of AM in some instances. One hypothesis could be that herds that purchase vaccines use them to prevent disease and consequently have lower AM consumption than herds purchasing fewer or no vaccines against these pathogens.

Salmonella spp. infection in piglets from Salmonella-positive breeding holdings

The dynamic of pig salmonellosis during the first weeks of life is barely known. Studies suggest that Salmonella prevalence is very low as the percentage of shedders is low (<9%), but they are usually based on analyses of a small amount of fecal matter, which yield poor diagnostic sensitivity. Thus the true prevalence of infection is unknown, and therefore the potential of these young pigs to become shedders.

Congenital tremor Type A-II in newborn piglets is caused by transplacental transmission of a novel pestivirus

Congenital tremor is a well-known phenomenon in newborn piglets. It is characterized by tremors of the head and limbs that vary in severity, but are reducing or even absent during sleep. They last for several weeks to months but decrease in severity as the pigs grow older. Historically, congenital tremor has been classified as type A, with defined pathological characteristics and partially known etiology, or type B, with unknown etiology.

Could avian H9N2 influenza viruses become a threat to swine? Lessons from experimental studies in the pig.

It is a classical but unproven hypothesis that pigs can serve as intermediate hosts between birds and humans in the generation of novel pandemic influenza viruses. Yet the single pandemic virus of likely swine origin is the 2009 pandemic H1N1 virus (2009 pdm), a virus with genetic components of swine, human and avian origin (reassortant).

Influence of gestation housing system on sow health and the transfer of maternal  immunity to the neonate

Although the conventional housing on slatted floor remains predominant in European pig farms, a variety
 of alternative housing systems exists for gestating sows. The consequences of these different environments 
on health of the mothers and on the immunity they transfer to their progeny remain  poorly known.

Characteristics of repeat-breeding female pigs on southern EU commercial farms

A repeat-breeding (RB) occurrence increases non-productive days of female pigs
(NPD), and consequently decreases herd productivity. However, characteristics of RB female pigs are not well defined or studied in swine. Also, few studies have compared lifetime reproductive performance between RB and non-RB female pigs.

PAPULAR DERMATITIS IN PIGS CAUSED BY MIDGE BITES IN NORTHERN IRELAND

Reports of biting midges are rare in the literature. The importance of parasitic
arthropods to pig production depends of the geographical location and the
production system used. The direct economic impact of biting midges on pig
production has not been studied

PRRSv INFECTION BY SEMEN IN A PIG UNIT IN NORTHERN IRELAND

PRRSv is enlisted as a Notifiable Disease in Northern Ireland (The Diseases of
Animals –Northern Ireland- Order 1981) after it was first diagnosed in 1997. The
prevalence of infection in 2011 was 36.6% of the Northern Irish pig producers.
In April 2013, the main boar stud of the island, located in the Republic of Ireland, was
diagnosed with PRRSv infection. This stud was supplying semen to around 70% of
producers in the whole island.
