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: ...
The Role of Supplemental Beef vs. Sugar during Pregnancy on Fetal and Offspring Developmental Programming in Swine
(North Dakota State University, 2019)
Sugar intake is linked to developmental programming of obesity and diabetes. We hypothesized that supplementing ground beef in place of sugar during pregnancy would reduce fetal and offspring developmental programming. ...
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 ...
Examining the Potential of the GALR2 Genotype as a Marker-Assisted Management Strategy to Improve Production Efficiencies and Carcass Characteristics in Crossbred Angus Finishing Steers
(North Dakota State University, 2020)
The objective was to determine how the interaction of implant strategies with the galanin receptor 2 genotype would influence feeding behavior, production efficiencies, carcass characteristics, and meat quality in finishing ...
Use of Soybean Hulls in Drylot Cow-Calf Diets
(North Dakota State University, 2021)
One hundred and twenty-one Red Angus beef cows were used to evaluate the effects ofsoybean hull inclusion in drylot beef cow diets. Cows were stratified by age, body weight (BW),and body condition score (BCS), and randomly ...
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 ...
