The objective of this study was to evaluate the correlation between serum PRRSv PCR positives and oral fluids PRRSv PCR positives, to evaluate the detection dynamics between serum and oral fluids PRRSv PCR positives, and to determine the effects of pooling samples.

Supplementing sow diets with 250 mg/kg of oregano essential oils during gestation and lactation did not affect the growth potential of and immune responses in suckling piglets.

Sows and piglets diets supplemented with probiotics are effective in maintaining animal performance and control of diarrhea during the nursery phase.

The results of the present study suggest that synbiotics exert similar effects with antibiotics on the nutrient digestibility and fecal microflora composition in growing pigs. Moreover, synbiotics can also decrease the fecal noxious gas emission in growing pigs.

Area regional disease control (ARDC) strategies are an important tool in the swine industry due to the ability of many swine diseases, most notably PRRS, to spread by methods other than direct animal contact.

The objectives of this study were to determine if oral fluid samples 1) could be collected from individually-housed mature boars under field conditions and 2) could be used to detect PRRSV infection.

The aim of the present study was to evaluate a blocking ELISA in the detection of serum antibodies to Lawsonia intracellularis, by comparison to the previously widely used immunofluorescent antibody test (IFAT).

The objective of the present study was to assess the applicability of qPCR to quantify PCV-2 loads in pooled serum samples as an easy-to-use PMWS diagnostic tool at the herd level.

An enhanced feed and water intake during lactation may increase weaning weight of piglets and decreases relative body weight loss of sows.

Metabolite combinations produced by L. plantarum strains are potential alternatives to antibiotics that could be used as growth promoter in postweaning piglets.

This is, to the authors’ knowledge, the first published study to determine the bacterial flora in skin and colostral milk samples of a limited number of sows with clinically healthy mammary glands.

To determine the prevalence of ASF in Senegal in 2006, we tested serum specimens collected from a sample of pigs in the 3 main pig-farming regions for antibodies to ASF virus.

Infection with I suis during the suckling period can have an impact on postweaning performance. Thus, calculations of the economic impact of coccidiosis need to include the effect of slower growth rates in the first few weeks after weaning, as well as a reduction in suckling pig performance.

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.
