Alternative Treatment Options For Controlling Anthelmintic-Resistant Haemonchus Contortus Populations In South Dakota Sheep Herds, Adam Sarah

Electronic Theses and Dissertations

Haemonchus contortus is a common economically important gastrointestinal nematode that obliges the survival and productivity of small ruminants, especially sheep and goats. Anthelmintic resistance is a primary challenge in ruminant health management programs in preventing and controlling the H. contortus populations; therefore, there is a great necessity in finding and developing natural plant products for use as alternatives to commercial anthelmintics for controlling H. contortus in pastured sheep and goats. This dissertation has three major aims conducted in three separate studies: the first in vivo one was to evaluate the extended effect of a springtime, combined-treatment with 3 anthelmintics having …

Performance Differences Between Two Groups Of Commercial Pigs Following Experimental Infection With Prrs Virus 1-7-4, Erin Little

Electronic Theses and Dissertations

Porcine reproductive and respiratory syndrome virus (PRRSV) is the costliest swine disease in North America. Vaccines and management alone have not been effective in controlling this disease. Genetic selection for resilience may be a complimentary approach for controlling PRRSV. The objective of this study was to estimate performance differences between two groups of pigs from the same commercial line following infection with PRRSV 1-7-4: 1) pigs sired by boars selected based on a standard index (TN-S), which emphasized feed efficiency and carcass quality; and 2) pigs sired by boars selected based on an experimental index (TN-E), which emphasized feed intake, …

Development And Evaluation Of Vaccine Candidates For Senecavirus A, Bishwas Sharma

Electronic Theses and Dissertations

Senecavirus A (SVA) has been associated with several outbreaks of vesicular disease (VD) since 2014 in major swine-producing countries around the world. The virus causes VD that is clinically indistinguishable from foot-and-mouth disease (FMD) in pigs. Currently there are no commercial vaccines available for SVA. Here, we developed a live attenuated SVA strain by mutating a wild type SVA strain SD15-26 (wt SVA). The live attenuated virus, rSVA mSacII, replicated less efficiently in cell cultures in vitro and expressed lower amounts of VP1 and VP2 capsid proteins than wt SVA. Most importantly, the rSVA mSacII virus failed to induce clinical …

Bovine Cellular And Innate Immune Response To Hemostatic Polysaccharides, Brian Kobylkevich

Electronic Theses and Dissertations

Chronic wounds are longstanding dermal wounds that do not heal in a normal amount of time and can commonly last for over a year. These wounds plague humans and farm animals alike. Wounds are characterized by chronic inflammation and are often painful, difficult to heal, have a high recurrence rate, and are potentially debilitating. Long term wounds that do not fully heal are distressing for both humans and animals, but understandably more resources have been directed towards humans. Some treatment options for humans may be suitable for adaptation into the field of animal care. Chronic lesions such as bovine digital …
