The Impact of Management Decisions and their Effect on Reproductive Performance of Beef Cattle
(North Dakota State University, 2014)
Two experiments were conducted to evaluate two management decisions made by beef cattle producers and their impacts on reproduction. In experiment 1, growth, attainment of puberty, and pregnancy rates were evaluated in ...
Effects of Distillers Dried Grains with Solubles Supplementation to Yearling Heifers Grazing Northern Great Plains Rangeland: Impacts on Subsequent Feedlot Performance and Meat Quality
(North Dakota State University, 2013)
Eighty two yearling heifers (319.5 ± 1.03 kg) were utilized in a completely randomized design to evaluate the effects of distillers dried grains with solubles (DDGS) supplementation on animal performance while grazing on ...
The Effects of Injectable Trace Mineral Supplements in Donor Cows at the Initiation of a Superovulation Protocol on Embryo Outcomes and Pregnancy Rates in Recipient Females
(North Dakota State University, 2018)
Concentrations of trace minerals within the body are known to impact reproductive processes. Thus, the current study analyzed the effects of using an injectable trace mineral supplement containing selenium, zinc, copper, ...
Biological Evaluation of the Associations Between Animal Size, Feeding Behavior, Blood Metabolites and Feed Efficiency in Beef Cattle
(North Dakota State University, 2017)
The biological variation in feed efficiency is regulated by multiple physiological mechanisms relevant to energy use in livestock species. The current study examined the associations between body composition, feeding ...
Impacts of Flax on Female and Male Reproductive Traits When Supplemented Prior to Breeding in Sheep
(North Dakota State University, 2018)
Two experiments determined the effects of flaxseed supplementation on reproductive parameters in sheep. In experiment one, 240 multiparous Rambouillet ewes were assigned to one of two treatments: basal ration alone or basal ...
Evaluating Standard Wet Chemistry Techniques and NIR Spectroscopic Models for Determining Composition and Potential Ethanol Yields of Multi-Species Herbaceous Bioenergy Crops
(North Dakota State University, 2011)
Herbaceous perennials represent a considerable portion of potential biomass feedstocks available for the growing bioenergy industry. Their chemical composition and biomass yields, which are important in determining ethanol ...
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 ...
Efficacy and Recovery of Cellulases Immobilized on Polymer Brushes Grafted on Silica Nanoparticles
(North Dakota State University, 2014)
Cellulosic biofuels can be more economical if cellulases are recovered and reused.
Cellulase and β-glucosidase were immobilized on poly(acrylic acid) brush particles. Impact of brush enzyme density on efficacy and recovery ...
Implementing High-Throughput Phenotyping at the NDSU Dry Bean (Phaseolus vulgaris l.) Breeding Program Using Unmanned Aerial Systems
(North Dakota State University, 2021)
Plant breeding has led to considerable yield gains to several crops. However, it alone might not be able to keep up with the growing demand for food. In this study, data extracted from UAS-collected RGB and multispectral ...
Using UAS Images to Remotely Estimate Soil Moisture Content in the Red River Valley
(North Dakota State University, 2021)
Accurate measurements of soil moisture in a timely manner are necessary in making critical management decisions, but it is often very difficult to obtain. Even though soil moisture can be measured on the ground using various ...
