Effects of Nutrient Restriction, Realimentation, and Parity on Umbilical Hemodynamics in the Pregnant Ewe
(North Dakota State University, 2016)
Sheep are normally managed within grazing systems; forage availability and quality are dependent upon seasonal conditions such as drought and humidity. It is therefore important for producers to know when during gestation ...
The Effect of Vitamin A Restriction on Marbling and Adipogenic Gene Expression in Commercial Angus and Simmental Steers
(North Dakota State University, 2017)
Vitamin A (Vit-A) restriction has been shown to increase marbling in cattle. Our hypothesis for this study was that a low Vit-A diet would increase marbling and improve meat quality characteristics while having no effect ...
Efficacy of Various Five-Day Estrous Synchronization Protocols in Sheep
(North Dakota State University, 2012)
The objective of this study was to determine the effects of various estrous synchronization protocols utilizing the five-day controlled internal drug releasing (CIDR) inserts that are infused with progesterone (P4) alone ...
Evaluation of the Relationship Between Size, Feeding Behavior, and Feed Efficency in Beef Cattle
(North Dakota State University, 2022)
Feed efficiency in cow-calf operations can be influenced by multiple environmental and physiological factors. The current study examined the association between body size (weight, frame score, and volume), linear body ...
Evaluation of Beef Cattle Temperament Using Infrared Thermography and Computer Vison Imaging Technologies
(North Dakota State University, 2022)
The aim of these studies are two-fold. The first, was to evaluate the use of infrared thermography (IRT) maximum, average, and minimum eye temperature (IRTMIN, IRTAVG, and IRTMAX, respectively) and percentage of eye white ...
The Effect of Hemp Byproduct Supplementation on Beef Quality
(North Dakota State University, 2022)
The supplementation of hempseed cake (hemp byproduct) could be considered an alternative protein and fiber source for ruminants such as cattle. Hempseed cake might be a successful alternative feed source due to cattle’s ...
Influence of Plasma Nuclear Magnetic Resonance Profile, Urea-Nitrogen, Glucose and Non-Esterified Fatty Acids on Dry Matter Intake in Developing Heifers and Mature Cows
(North Dakota State University, 2022)
The objective of this experiment was to determine if nuclear magnetic resonance (NMR) profiles or blood metabolites could explain dry matter intake (DMI) in developing heifers and/or mature cows in the weeks leading to ...
Are Infrared Thermography, Automated Feeding Systems, And Heart Rate Variability Measures Capable of Characterizing Group-Housed Sow Social Hierarchies?
(North Dakota State University, 2022)
Group gestation housing is becoming standard practice in commercial swine production. Although group housing promotes behavioral variability within the breeding herd, it can cause several management challenges for producers ...
The Effects of Arginine on Reproductive Performance in Ewes
(North Dakota State University, 2010)
Reproductive performance is the largest determinant of income in the livestock
industry. In the U.S. sheep industry, embryonic and fetal deaths during pregnancy account
for almost half of the total number of fertilized ...
The Role of Distillers Dried Grains with Solubles in Sulfur Toxicity in Ruminants
(North Dakota State University, 2010)
One of the challenges with using ethanol co-products is the potential for increased dietary S
concentration. Dietary S concentration has been implicated as a cause of
polioencephalomalacia (PEM) in ruminants. The focus ...
