Temperament Evaluation in Beef Cattle: Understanding Evaluator Bias Within Subjective Measurements of Docility Score, Temperament Score, and Qualitative Behavior Assessment
(North Dakota State University, 2016)
An experiment was conducted to quantify evaluator bias and determine the impacts bias may have on genetic evaluations. Three subjective evaluation methods were recorded (n = 806) at weaning, including docility score (DS; ...
2015 National Pork Retail Benchmarking Study
(North Dakota State University, 2016)
The objective of this study was to quantify pork quality variation in the retail self-serve meat case nationwide. Center-cut loin chops (CCLC) (n=3795) were analyzed in-store for subjective color and marbling scores (2.85 ...
Does Beef Inclusion in a Modern American Diet Influence Risk Factors for Obesity-related Metabolic Disorders via a Swine Biomedical Model
(North Dakota State University, 2016)
Using swine as a model for humans, this study was conducted to determine if replacing the sugar present in the average American diet (SUG) with ground beef (GB) would alter developmental body composition, onset of puberty, ...
The Exploration of a Four-Platform Standing Scale in the Application of Measuring Temperament in Beef Cattle
(North Dakota State University, 2016)
To assess the validity of a four-platform standing scale (FPSS) to measure cattle
temperament, calves were evaluated at weaning age with an objective four-platform standing
scale (FPSS) and subjective methods of docility ...
Extracting Carotenoids from Corn Industry Coproducts
(North Dakota State University, 2016)
Two experiments were completed to develop methods for extracting xanthophylls from corn industry co-products, post fermentation (PF) corn oil and corn gluten meal (CGM). A solid phase extraction (SPE) method was used to ...
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 ...
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 ...
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.
Effects of Grain Type and Oil Concentration of Corn Dried Distillers Grains Plus Solubles of Digestion, Finishing Performance, and Carcass Quality
(North Dakota State University, 2016)
Changes in ethanol processing have resulted in a reduction of oil in the final coproduct, DDGS, available as a feedstuff. Lowering the oil concentration can decrease the total energy in the diet and, therefore, could affect ...
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 ...
