| effect of liquid swine manure rate, incorporation, and timing of rainfall on phosphorus loss with surface runoff. | excessive manure phosphorus (p) application increases risk of p loss from fields. this study assessed total runoff p (tpr), bioavailable p (bap), and dissolved reactive p (drp) concentrations and loads in surface runoff after liquid swine (sus scrofa domesticus) manure application with or without incorporation into soil and different timing of rainfall. four replicated manure p treatments were applied in 2002 and in 2003 to two iowa soils testing low in p managed with corn (zea mays l.)-soybean ... | 2008 | 18178885 |
| isolate designation and characterization of toxoplasma gondii isolates from pigs in the united states. | pigs are considered to be the most important meat source of toxoplasma gondii for humans in the united states. in the present study, 168 t. gondii isolates (designated tgpgus15-182) from various sources were genotyped using 10 polymerase chain reaction-restriction fragment length polymorphism (pcr-rflp) markers (sag1, sag2, sag3, btub, gra6, c22-8, c29-2, l358, pk1, and apico). genotyping data from an additional 14 isolates collected from t. gondii-infected pigs in maryland were included for ana ... | 2009 | 19245283 |

| quantitative approach for the risk assessment of african swine fever and classical swine fever introduction into the united states through legal imports of pigs and swine products. | the us livestock safety strongly depends on its capacity to prevent the introduction of transboundary animal diseases (tads). therefore, accurate and updated information on the location and origin of those potential tads risks is essential, so preventive measures as market restrictions can be put on place. the objective of the present study was to evaluate the current risk of african swine fever (asf) and classical swine fever (csf) introduction into the us through the legal importations of live ... | 2017 | 28797058 |
