The characterization of Haemophilus parasuis strains is very important for the study of the epidemiology of this agent within and between herds. In the present study, the characterization of H. parasuis field isolates by serotyping and genotyping was compared, and…
Evaluation of Emerging Technologies in Swine Manure Management
Our findings in the project indicates that in a wean to finish system: Antibiotics may not be necessary for performance of pigs in a wean to finish system. Antibiotics modifies the micro-flora of the gastrointestinal tract by reducing total aerobes…
Nutrient and Pathogen Losses to Subsurface Tile Drainage from Swine Manure
Land application of swine manure on tile-drained soils has become a controversial issue in some swine producing areas because of uncertainties regarding the leaching of nitrates, phosphorus, and pathogens through the soil and into tile drainage water. A study was…
Inoculation of Bacterial Pathogens to Control Disease
This study compared 3 different interventions to control Haemophilus parasuis mortality in nursery pigs. Both a commercial and an autogenous vaccine had no significant effect in this farm system. In contrast, a reduction of more than 50% mortality was observed…
Effect of probiotics in the health and performance of nursery pigs raised in conventional or antibiotic/growth promoter free farms
We compared the health and performance of weaned pigs in a high health herd between groups receiving low level antibiotics in the feed to groups receiving probiotic in the feed and no antibiotics. Performance and health were similar between the…
