SDSU Beef Day 2020 Summary Publication
Increased estradiol is the primary signal to initiate standing estrus, and cows that exhibit estrus prior to fixed-time artificial insemination have greater pregnancy rates than cows that do not. Therefore, understanding what factors may be present at the ovary that may regulate estradiol production is critical. A previous study reported that bovine follicles with greater follicular fluid concentrations of estradiol had decreased expression of GnRH-I and GnRH-II in granulosa cells (GC). The objective of this study was to characterize relative abundance of GnRH-I and -II mRNA within GC of follicles at specific stages of development. Beef cows were synchronized, and …

Development And Diagnostic Application Of Monoclonal Antibodies Against Swine Acute Diarrhea Syndrome Coronavirus (Sads-Cov), Molly Kroeger
Development And Diagnostic Application Of Monoclonal Antibodies Against Swine Acute Diarrhea Syndrome Coronavirus (Sads-Cov), Molly Kroeger
Schultz-Werth Award Papers
Swine Acute Diarrhea Syndrome Coronavirus (SADS-CoV) is a member of the Coronaviridae family. The virus is associated with severe small intestine inflammation and diarrhea in suckling piglets. In 2017, SADS-CoV was first detected and identified as the causative agent of a devasting swine disease outbreak in southern China. Routine monitoring and early detection of the source of infection is therefore integral to the prevention and control of a SADS-CoV outbreak in the United States. However, the United States does not currently have any diagnostic or surveillance tests to identify this emerging disease. To address these industry needs, we developed monoclonal …
Evaluation Of Anterior Pituitary Leptin Receptor Expression In Pregnant And Non-Pregnant Gilts, Juliana Pederson, Jeffrey Clapper
Evaluation Of Anterior Pituitary Leptin Receptor Expression In Pregnant And Non-Pregnant Gilts, Juliana Pederson, Jeffrey Clapper
Schultz-Werth Award Papers
Successful reproduction in porcine depends on the coordinated synthesis and release of several hormones from the hypothalamus and anterior pituitary gland. Leptin, a hormone produced from adipocytes, interacts with other specific reproductive hormones and affects the reproductive success in swine. However, the full extent of leptin’s impact is unclear. This experiment sought to examine the difference in expression between the anterior pituitary gland leptin receptors in pregnant and non-pregnant pigs to confer the impact leptin has on reproductive success. Twentyfour crossbred gilts of similar age and weight had their estrus cycles synchronized and then were bred via artificial insemination. The …

Teaching Natural And Artificial Selection In Production Agriculture, Madhav P. Nepal, Clayton W. Scott
iLEARN Teaching Resources
In this lesson, students will learn how natural selection and artificial selection impact both production agriculture and biological sciences. A natural selection is a mechanism that favors heritable traits that increase species survival and reproduction. Artificial selection is a selective breeding, where humans select for desirable traits in agricultural products.

Integration Of Crop-Livestock Systems: An Opportunity Toprotect Grasslands From Conversion To Cropland In The Us Great Plains, Alexander J. Smart, Daren Redfearn, Robert Mitchell, Tong Wang, Cody Zilverberg, Pete J. Bauman, Justin D. Derner, Julie Walker, Cody Wright
Native Plant Focused Publications
The Great Plains is a mixture of cropland and grassland mainly used for agricultural purposes, with grasslands under continual threat of conversion to cropland. Agriculturists are advocating for the integration of crop-livestock systems (ICLS) to recouple nutrient cycles, improve biodiversity, and increase resilience of agricultural operations. We address the benefits of ICLS in the Great Plains, contending that focus on improving soil health and financial stability of agricultural operations should reduce the conversion of grasslands to cropland. Using US Department of Agriculture National Agricultural Statistics Service Census of Agriculture survey data from the 1925 to 2017 category “cropland used only …

Distribution, Density, Movement, And Support For Management Of Mountain Sucker, Pantosteus Jordani, In The Black Hills Of South Dakota, Seth J. Fopma
Distribution, Density, Movement, And Support For Management Of Mountain Sucker, Pantosteus Jordani, In The Black Hills Of South Dakota, Seth J. Fopma
Electronic Theses and Dissertations
Mountain Sucker, Pantosteus jordani, is a cold-water species native to the Intermountain West. Fringe populations of Mountain Sucker have experienced declines in recent decades. The population of Mountain Sucker found in the Black Hills of South Dakota represents the eastern fringe of the species’ native range. Recognized as both an indicator of biologic health and as a species of greatest conservation need in South Dakota, recent studies have suggested significant declines in both distribution and abundance. Despite the recent study of Mountain Sucker in the region, increased understanding of Mountain Sucker ecology is needed to effectively manage for the conservation …
