Previous studies revealed that 22% to 40% of sows in confinement operations are affected with urinary tract infections (UTI) and UTI contribute to sow mortality. This study was designed to determine if UTI are detrimental to sow performance and to identify the stage of the production cycle that sows are at greatest risk of acquiring UTI. The study was conducted on a commercial sow farm and urin...

Multinucleate parasitic cells (spherules) of Coccidioides immitis isolates produce a membranous outer wall component (SOW) in vitro which has been reported to be reactive with antibody from patients with coccidioidal infection, elicits a potent proliferative response of murine immune T cells, and has immunoprotective capacity in a murine model of coccidioidomycosis. To identify the antigenic co...

Achromobacter xylosoxidans, a Pseudomonaslike bacterium, contaminated a boar stud laboratory’s water distillation and delivery system that was used for extension of raw semen for artificial insemination. In sow herds that used the contaminated semen, conception rates decreased and vulvar discharges, culled sows, and nonproductive sow days increased. Thorough diagnostic testing revealed that A x...

pepper plant capsicum annuum l. has great nutritional value and many pharmaceutical properties but its sensitivity to pests such as aphis gossypii glover, especially in drought stress conditions, has limited its production. to evaluate the effect of drought stress on the population and damage rate of this pest in greenhouse condition, four moisture treatments including; full irrigation, 15, 30 ...

In order to minimize odor and manage nutrients in liquid pig manure we need to be able to predict what operational practices most influence the concentrations of volatile fatty acids (VFAs), ammonium nitrogen (NH(4)(+)-N), and other nutrients present in the manure. To determine this, we collected manure from 15 pig operations in southwestern Ontario in the fall of 2001 and 2002 and spring of 20...
