Swine outbreaks of pandemic influenza A (pH1N1) suggest human introduction of the virus into herds. This study investigates a pH1N1 outbreak occurring on a swine research farm with 37 humans and 1300 swine in Alberta, Canada, from 12 June through 4 July 2009.

The objectives of this field survey were to evaluate the effects of several promising swine waste-management and treatment technologies on reducing Salmonella presence and populations and to characterize the diversity of Salmonella isolates recovered from the waste streams using serotyping and antibiotic-susceptibility analysis.

A herd of pigs being reared for breeding and fattening, in which there had been incidences of abortion and wasting, reduced growth rates and an increase in mortality for the past year, were tested for Mycobacterium infection by pathological examinations, skin test, serology and Mycobacterium culture.

The aim of the present study was to further elucidate the eff ect the route of Fe supplementation may have on infectious diseases in piglets, and the relationship between Hb levels during suckling and growth from birth to slaughter.

Barley-based diets have more beneficial effects on gut health, oat-based diets have higher potential to enhance beneficial microbial populations and endogenous β-glucans show better prebiotic properties.

Previous studies have linked levels of porcine endogenous retroviruses (PERV) with poor health and disease in pigs. To determine the levels of expression of PERVs and their potential association with disease expression, real-time reverse transcriptase (RT) PCR assays were used to assess PERV-ABC, PERV-C and PERV-A/C levels in three commercial swine operations in the United States.

The results of this study indicates a low risk of prolonged carriage of FMD virus in the human nasal cavities after exposure to infected animals.

The objective of this study was to examine the influence of transport conditions on the behaviour, physiology and welfare of pigs in eastern and western Canada, in both summer and winter. Our goals were to evaluate differences between truck types, truck compartments and seasons in each region, and to use this information to identify problem areas and potential solutions.

A research protocol was designed to eradicate the virus in pigs sourced from a PRCV positive sow herd. The sow herd is a 150 farrow to finish herd, under one roof, and is PRRS and Mycoplasma hyopneumoniae negative. Forty piglets were weaned from nursing gilts/sows at 5 days of age and removed to a separate nursery which had been thoroughly disinfected and cleaned.

The use of mycotoxins absorbents in sever vomitoxin contaminated diets may reduce the negative impact of vomitoxin on piglet performance.

Feeding low CP, AA supplemented diets can help to improve poor growth performance and enteric disorders of the weaned pigs.

The results obtained in this study suggest that UV(254) is an effective means to inactivate PRRSV on commonly encountered farm surfaces and materials and inactivation can be accomplished following 10min of exposure.

Supplementation of HSCAS is effective in preventing the negative effects of dietary aflatoxin in young pigs as measured by growth and serum chemistry parameters. Supplementing with antioxidant does not mitigate most negative physiological effects associated with aflatoxin consumption.

Considering the results of this study, O. porcinus is a reservoir for ASFV and most likely acts as vector for ASFV in Madagascar, but its apparent restricted distribution may limit its role in the epidemiology of the disease in domestic pigs.

The objective of this study was to evaluate the efficacy of administering potassium penicillin G via drinking water to weaned pigs to reduce mortality and spread of infection caused by Streptococcus suis.

An observational study was conducted to determine the prevalence of Isospora suis oocysts in fecal samples from suckling piglets in Ontario, and to evaluate the relationship between the presence of I. suis oocysts and diarrhea.
