Effect of pig slurry solids on aeration efficiency and odour generation
January 1, 2005
Two laboratory-scale experiments were carried out in this study to determine the effect of slurry solids content on aeration efficiency and the odour generation potential for the treated slurry...
Size distribution and composition of particles in raw and anaerobically digested swine manure
January 1, 2005
The design of efficient manure treatment systems requires a better characterization of particle and nutrient distribution in manure slurries. The aim of this project was to study particle size, COD,...
Detection and occurrence of antimicrobially resistant E-coli in groundwater on or near swine farms in eastern North Carolina
January 1, 2005By Anderson
The use of antibiotics for growth promotion and disease treatment by the commercial swine industry has led to high proportions of multiple antibiotic-resistant enteric bacteria being shed by these...

The Effect of Space Allowance and Season on the Welfare of Early Weaned Piglets Under Commercial and Expermental transport conditions
December 13, 2004By Nora J. Lewis|S. Wamnes
Early weaning is a stressful period as reflected by high serum cortisol levels. Transport can add to this stress. In winter, cold environmental temperatures result in cold truck temperatures, lower...

Impact of early weaning and photoperiod manipulation on sow and piglet welfare
November 3, 2004By Janeen L. Salak-Johnson PhD
Animals adapt more readily to photoperiod cues than other environmental cues since photoperiod is more predictable and consistent over time. Previous work has shown limited (if any) affects of...

Utilization of Crystalline Amino Acids by the Gut in Growing Pigs
November 1, 2004By Nathalie L. Trottier
Conventional diets containing corn and soybean meal fed to growing pigs can be reduced in protein when a portion of the protein can be replaced by crystalline amino acids. These amino acids allow the...
