The Impact of Reproductive Technologies on Beef Cattle and Management
(North Dakota State University, 2016)Two experiments were conducted to evaluate producer management decisions that may impact beef cattle reproductive efficiency. The over-arching hypothesis was that critical breeding management decisions would positively ... -
Impacts of Beef Cow Nutrition on Conceptus Development
(North Dakota State University, 2013)Two experiments were conducted to determine the effect of maternal nutrient restriction followed by realimentation during early to mid-gestation on uterine blood flow (BF), maternal performance, and conceptus development ... -
The Role of Maternal Protein Intake During Late Gestation on Placental Vascular Function
(North Dakota State University, 2013)Global nutrient restriction or excess can influence umbilical hemodynamics in sheep fetuses (Chapter 2). We hypothesized that a specific component of the diet, namely maternal metabolizable protein (MP), would alter placental ... -
Influence of Cut, Cooking Method, and Post-Mortem Aging on Beef Palatability
(North Dakota State University, 2013)The objectives of these studies were to determine the effects of cut, cooking method, and postmortem aging on improving consumers' perception of beef. Consumers evaluated bottom round, top sirloin, ribeye, and a value cut ... -
Genetic Markers, Cattle Disposition, and Stress Relative to Variations in Beef Tenderness
(North Dakota State University, 2012)The objective of this research was to evaluate the efficacy of genetic markers, disposition, and animal stress on variations in beef tenderness. Warner-Bratzler shear force (WBSF) values on 570 mixed breed heifers and ... -
Supplementing Metabolizable Protein to Ewes during Late Gestation: Effects on Ewe and Offspring Performance
(North Dakota State University, 2013)We hypothesized that MP intake at or above requirements during late gestation would improve dam and offspring performance. In year 1, ewes received one of three isocaloric dietary treatments during late gestation: 60MP1: ... -
Computer Vision System as a Tool to Estimate Pork Marbling
(North Dakota State University, 2017)Currently pork marbling is assessed subjectively in the industry, because of the limited methods and tools that are suitable for the industry. In this dissertation, we are devoted to develop a computer vision system for ... -
Reproductive and Nutritional Impacts of Dried Distiller's Grains with Solubles on Growing Rams and Feedlot Lambs
(North Dakota State University, 2017)Byproduct supplementation in livestock rations is viable and can lead to increased returns to producers. Increasing the inclusion of dried distiller’s grains with solubles (DDGS) was hypothesized to increase growth performance ... -
The Impact of Age and Level of Nutrient Consumption on Pancreatic Insulin Production in Ruminants
(North Dakota State University, 2016)Video summarizing Ph.D. dissertation for a non-specialist audience. -
The Effects of the Nitric Oxide (NO) System and Nutritional Plane on Ovarian Function
(North Dakota State University, 2015)Researchers predict a world population of approximately 9.5 billion people by the year 2050. Current resources, including the amount of meat that is produced, would not be able to sustain that population. Therefore, the ...
