Inoculation of Bacterial Pathogens to Control Disease
October 1, 2003By Carlos Pijoan
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...

Corn Particles Size and Pelleting Influence on Fecal Shedding and Enteric Colonization of Salmonella Typhimurium
September 22, 2003By Steve S. Dritz
Grinding corn to a finer particle size has been shown to have beneficial effects on growth, feed efficiency, and digestibility. The trial demonstrated improvements in growth and efficiency. However,...

Factors affecting the behavior of early-weaned piglets
September 19, 2003By Stephanie Torrey|Tina Widowski
Early weaned piglets often develop belly-nosing and sucking or chewing on the navels or ears of other pigs. This behavior is considered a problem because recipient pigs can develop lesions, and those...

Effect of chlorate treatment on transmission of Salmonella in swine during lairage and transport
September 15, 2003By Todd R. Callaway
Chlorate can be used to reduce Salmonella in pigs. However, it must reach the lower gut in order to kill Salmonella. Therefore, although chlorate will work to reduce Salmonella during the lairage...

Evaluation of a Chlorate Treatment on Post-Weaning Diarrhea Caused by E. Coli in Weaned Pigs
September 15, 2003By Tom S. Edrington PhD
In a series of five experiments, we evaluated the effect of chlorate on reducing gut populations of the E. coli capable of causing post-weaning diarrhea. In three of the experiments, we had a model...

Biochemical Characterization of Pork Quality
September 2, 2003By Matthew Doumit
Sires from Duroc, Berkshire, Yorkshire and Pietrain breeds were used to produce crossbred progeny, free of the HAL-1843TM gene, that exhibit pork quality differences. Loin muscle temperature, color,...

Investigating the genetic relatedness among Salmonella species isolated in transportation trucks, holding pens and from swine at slaughter
July 31, 2003By Annette O’Connor
Previous studies have suggested strongly that the lairage is a source of Salmonella to swine. Using more refined tools to determine relatedness between isolates we have reinforced this finding. More...
