Maternal Nutritional Plane and Endogenous Retroviral Gene Elements, Pregnancy Hormones, and Placental Vascularity and Angiogenic Factors during the Establishment of Pregnancy in Beef Cattle
(North Dakota State University, 2016)
In order to meet the projected food demands by 2050, animal agriculture must increase
production of animal products on the same or decreased land area through increased efficiency.
Early gestation is one area to increase ...
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 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.
Maternal Nutrition, One-Carbon Metabolites, and Programming of Fetal Development During Early Gestation
(North Dakota State University, 2019)
Crossbred Angus heifers (n = 14) were bred via AI, assigned to nutritional treatment (CON = 100% of requirements for 0.45 kg/d gain and RES = 60% of CON) and ovariohysterectomized on d 50 of gestation. Fetal liver, muscle ...
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 ...
Factors Affecting Testicular Growth and Development in the Beef Bull
(North Dakota State University, 2019)
At present no single parameter can predict potential daily sperm production (DSP) in bulls. Sertoli cells (SC) are responsible for nourishing and providing physical support to germ cells (GC) throughout spermatogenesis. ...
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 ...
The Impact of Digestive Enzymes in the Ruminant Animal
(North Dakota State University, 2016)
Understanding the enzymatic activity in ruminant digestive systems is essential for securing adequate growth, reproduction and overall metabolism. In order to evaluate the impact of various nutritional sources and dietary ...
Independent Methods to Improve Meat Quality Including Genetic Technologies, Modified Processing, and Growth Promotants in Beef
(North Dakota State University, 2015)
Three independent studies were done to investigate how genetic factors, carcass management, and exogenous growth promotant programs influence meat quality attributes, palatability, and protein expression in beef. The first ...
