Comparative transcriptomic analysis of rectal tissue from beef steers revealed reduced host immunity in Escherichia coli O157:H7 super-sheddersDownload
Super-shedder cattle are a major disseminator of E. coli O157:H7 into the environment, and the terminal rectum has been proposed as the primary E. coli O157:H7 colonization site. This study aimed to identify host factors that are associated with the super-shedding process by comparing...
A genome-wide association study of fetal response to type 2 porcine reproductive and respiratory syndrome virus challengeDownload
Control of porcine reproductive and respiratory syndrome (PRRS) is economically important for the swine industry worldwide. As current PRRS vaccines do not completely protect against heterologous challenge, alternative means of control, including enhanced genetic resilience, are needed. For...
Bioinformatic analyses in early host response to Porcine Reproductive and Respiratory Syndrome virus PRRSV reveals pathway differences between pigs with alternate genotypes for a major host response QTLDownload
Bao, Hua, Schroyen, Martine, Rowland, Robert R.R., Guan, Le L., Stothard, Paul, Reecy, James M., Fritz-Waters, Eric, Koltes, James E., Kommadath, Arun, Plastow, Graham S., Eisley, Christopher, Tuggle, Christopher K. , Dekkers, Jack C.M., Lunney, Joan K., Choi, Igseo
Background A region on Sus scrofa chromosome 4 (SSC4) surrounding single nucleotide polymorphism (SNP) marker WUR10000125 (WUR) has been reported to be strongly associated with both weight gain and serum viremia in pigs after infection with PRRS virus (PRRSV). A proposed causal mutation in the...
Although infectious diseases impose a heavy economic burden on the cattle industry, the etiology of many disorders that affect livestock is not fully elucidated, and effective countermeasures are often lacking. The main tools available until now have been vaccines, antibiotics and antiparasitic...
Genome wide association studies (GWAS) identify QTL on SSC2 and SSC17 affecting loin peak shear force in crossbred commercial pigsDownload
Of all the meat quality traits, tenderness is considered the most important with regard to eating quality and market value. In this study we have utilised genome wide association studies (GWAS) for peak shear force (PSF) of loin muscle as a measure of tenderness for 1,976 crossbred commercial...
Genome-wide association studies (GWAS) identify a QTL close to PRKAG3 affecting meat pH and colour in crossbred commercial pigsDownload
Background Improving meat quality is a high priority for the pork industry to satisfy consumers’ preferences. GWAS have become a state-of-the-art approach to genetically improve economically important traits. However, GWAS focused on pork quality are still relatively rare. Results Six...
Long-term forage dynamics in pastures sprayed with residual broadleaf herbicide: A test of legume recoveryDownload
Legumes such as alfalfa (Medicago sativa L.) and white clover (Trifolium repensL.) are important components of northern temperate pastures where they increase forage productivity and quality, but are susceptible to decline when exposed to broadleaf herbicides. Little is known about the long-term...

Protected areas (PAs) remain central to the conservation of biodiversity. Classical PAs were conceived as areas that would be set aside to maintain a natural state with minimal human influence. However, global environmental change and growing cross-scale anthropogenic influences mean that PAs can...
Transcriptomic and epigenetic profiling of the lung of influenza-infected pigs: A comparison of different birth weight and Susceptibility groupsDownload
Influenza viruses are a common cause of respiratory disease in swine. Infections range in severity from asymptomatic to causing significant morbidity. The main objective of this study was to compare lung transcriptomic and epigenetic responses to influenza infection in pigs from high or low birth...
Maternal and fetal predictors of fetal viral load and death in third trimester, type 2 porcine reproductive and respiratory syndrome virus infected pregnant giltsDownload
Minimal research has focused on understanding mechanisms underlying porcine reproductive and respiratory syndrome virus (PRRSV) induced reproductive failure. We have completed a large-scale project investigating phenotypic and genotypic predictors of reproductive PRRS severity in which numerous...
