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.
