The Use of Subjective and Objective Methods of Behavioral Evaluation in Swine and Dairy Cattle
(North Dakota State University, 2017)
The objectives of the studies described in this thesis were to quantify livestock behavior and improve animal wellbeing. Subjective and objective evaluation methods can be used as an estimation parameter of animal welfare. ...
The Relationship between Pre-Harvest Stress and Carcass Characteristics and the Ability to Qualify for Kosher on Beef Steers and Heifers
(North Dakota State University, 2013)
The objective of this study was to determine if there is a difference in pre-harvest stress and carcass characteristics between kosher and not-qualified-as kosher cattle. Cattle that had a shorter time from gate to ...
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 ...
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: ...
The Effects of Feeding Seaweed Extract in the Diet of Swine on Gut Health, Performance, Carcass Characteristics, and Pork Quality
(North Dakota State University, 2017)
Consumers are concerned about antibiotic and ractopamine usage; therefore, alternatives need to be found. Objectives of this study were to investigate the effects of using seaweed as an alternative feed supplement and ...
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 ...
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 ...
Application of Nanoparticles in Livestock Manure for Understanding Hydrogen Sulfide and Greenhouse Gas Reduction Mechanism
(North Dakota State University, 2018)
The agricultural sector is one of the sources of greenhouse gases (GHGs) emission, especially methane (CH4), and contributing approximately 250 million metric ton carbon dioxide (CO2) equivalent emission per year. Almost ...
