This study tested the hypothesis that late weaning and the availability of creep feed during the suckling period compared with early weaning, improves feed intake, decreases stress and improves the integrity of the intestinal tract.

Hulless barley in piglet diets may reduce Salmonella typhimurium transmission among penmates.

The aim of this study was to evaluate the effect of porcine recombinant somatotropin (rpST) administered to piglets during their first week of life, on metabolic and somatometric variables. A total of 220 piglets born from 40 hybrid Landrace x Large White sows were used.

Swine workers had serologic evidence for infection with both swine and human influenza viruses and were exposed to diverse influenza virus strains circulating in pigs. Influenza virus surveillance among pigs and swine workers should be encouraged to better understand cross-species transmission and diversity of influenza viruses at the human-swine interface.

The objective of this study was to assess in pigs the pathogenicity and virulence of 3 strains of Salmonella spp capable of causing atypical salmonellosis in cattle.

E. coli played a significant role in the aetiology of pyelonephritis. Neutrophils were involved in the first line of defence. CD3ε T-lymphocytes were involved in both the acute and chronic inflammatory response while a humoral immune response was most pronounced in later inflammatory stages. The observed renal lesions correspond with an ascending bacterial infection with presence of intra-renal reflux.

It was concluded that natural infection of PEDV in the pregnant gilts and sows caused a reduction of subsequent reproductive performance.

Pigs can become MRSA positive in the short period of time during transportation from the farm to stunning at the abattoir.

A longitudinal study of Clostridium difficile colonization in piglets was performed on a conventional swine farm in Ontario, Canada. Fecal samples were collected from 10 sows prior to their expected farrowing date, and then from all their piglets on days 2, 7, 30, 44 and 62 of life.

Animals firstly infected with SwH1N1 virus and latter infected with pH1N1 exhibited undetectable viral RNA load in nasal swabs and lungs after challenge with pH1N1, indicating a cross-protective effect between both strains.

Porcine reproductive and respiratory syndrome (PRRS) and Mycoplasma hyopneumoniae (M hyo) are re-emerging diseases of pigs and growing threats to the global swine industry. For sustainable disease control, it is critical to prevent the spread of these pathogens between pig populations; therefore, a clear understanding of the role of aerosol transmission is needed along with information on how to reduce this risk.

The use of Lactobacillus plantarum as a probiotic, may improve growth performance and immunity in piglets.

Conventional serum storage protocols (freezing or refrigeration at 4°C) preserves PRRSV and anti-PRRSV antibody in oral-fluid diagnostic samples without the use of preservatives.

Since it was first reported in 1995, porcine reproductive and respiratory syndrome (PRRS) has become one of the most important swine diseases in China. A large number of field PRRSV strains have been isolated from different regions of China at different times, especially after a highly pathogenic PRRSV emerged in 2006.

A nutritional gel supplementation reduces the negative impact of vaccination on piglet behaviour.

The extent of inflammation associated with tail biting in finishing pigs was evaluated. Tail histopathology, carcass condemnation and the concentration of three acute phase proteins (APPs), C-reactive protein (CRP), serum amyloid-A (SAA) and haptoglobin (Hp), were examined in 12 tail-bitten and 13 control pigs.
