Identification of biological factors responsible for differences in feed efficiency between selection lines for residual feed intake- NPB 07-161, Selection lines to enhance genetic selection for feed efficiency – NPB 07-139
September 18, 2009By Jack C.M. Dekkers
Feed for the growing phase is the largest variable cost in pork production and these costs are on the rise. Thus, research that reduces feed required for pork production can result in substantial...

International collaboration to investigate the sensitivity and specificity of Mycoplasma hyopneumoniae PCR assays
July 31, 2009By Eileen Thacker
Mycoplasma hyopneumoniae (MHYO) remains a significant source of economic loss for today’s swine industry. Reliable diagnosis of this organism continues to be a challenge as demonstrated by the...

Selection for increased intramuscular fat and its effect on other quality traits and the fatty acid composition of pork
April 2, 2009By Tom Baas
Long-term selection for increased lean has come at the expense of meat quality traits, namely IMF percentage, objective loin color, and eating quality traits such as flavor and off-flavor. Results...

Role of Role of F4/F18 negative E. coli in post-weaning diarrhea and edema disease
February 19, 2009By Nancy Cornick
Veterinary diagnostic laboratories recover E. coli strains from sick piglets (with and without other pathogens) that do not encode for commonly encountered fimbrial adhesins but do contain genes for...

Enhanced virulence and treatment of multiple antibiotic resistant Salmonella choleraesuis in swine
October 3, 2008By Dr. Steve Carlson|Michael Kimber
Previous studies revealed that protozoa (amoebae) can augment the virulence (ability to cause disease) of certain Salmonella strains that are resistant to multiple antibiotics. This phenomenon has...

Effects of high and low virulent PCV2 on activated PBMC populations
August 26, 2008By Dr. Eileen Thacker
Porcine circovirus type 2 (PCV2) associated diseases (PCVAD) have been an important cause of mortality and economic loss to the swine industry. The importance of virulence between different virus...

Investigations on breed-dependent differences in susceptibility to PCV2
July 11, 2008By Tanja Opriessnig
Anecdotal information from producers and veterinarians in the field suggests that there are differences in susceptibility to porcine circovirus type 2 associated disease (PCVAD). Some producers have...

Oxygen consumption and energy digestibility of soybean meal and corn or corn co-product diets fed to grow-finish swine
January 2, 2008By Wendy Powers
Diets containing corn or corn co-products were fed to swine over 6 feeding phases, starting at 18 kg bodyweight and concluding at market weight. The corn co-product diets contained increasing levels...

Comparison of the virulence of PCV2 isolates from field cases with and without hallmark lesions of lymphoid depletion
August 15, 2006By Patrick Halbur
To our knowledge, this is the first report to demonstrate a clear difference in virulence between two well-characterized PCV2 isolates in a controlled experimental setting using a SPF pig model...

Prevention of Edema Disease Using a Probiotic Expressing Shiga Toxin 2e Receptor Mimic
February 13, 2006By Nancy Cornick
Edema disease is a naturally occurring infection of weaned piglets caused by E. coli bacteria that produce Shiga toxin. This toxin is absorbed from the gut into the blood stream and causes the...
