Effects of Implanting Strategy and Zilpaterol Hydrochloride on the Calpain Proteolytic System in Sectioned Beef Steaks for Two Time Periods
(North Dakota State University, 2016)The objective of this study was to evaluate the impact of an anabolic implant and its use with the beta-adrenergic agonist zilpaterol hydrochloride (ZH) the calpain proteolytic system activity across specific areas of the ... -
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, ... -
The Effects of Late Gestational Exercise on Colostrum Quality and Neonatal Immunoglobulin Absorption
(North Dakota State University, 2021)To investigate the effects that late gestational exercise has on ewe performance and colostrum IgG levels, and to evaluate how it impacts neonatal serum IgG absorption and future performance, thirty-two multiparous Dorset ... -
Effects of Linseed Meal on Growth and Reproductive Performance in Ruminants
(North Dakota State University, 2011)Linseed meal (LSM) was fed to ovariectomized ewes exposed to estradiol 17-ß (E2) implants over time, and LSM was supplemented to beef cows during late gestation and early lactation to evaluate the estrogenic potential ... -
Effects of Maternal Nutrition on Fructose, Glucose, and Cationic Amino Acid Transporter Expression in Bovine Utero-Placental Tissues from Days 16 to 50 of Gestation
(North Dakota State University, 2016)Poor Maternal nutrition has been implicated to reduce nutrient transport to the conceptus. Therefore, we hypothesized that maternal nutrition and day of gestation would impact mRNA expression of nutrient transporters GLUT1, ... -
Effects of Maternal Nutrition, Intrauterine Growth Restriction (IUGR), and Estrogen (E2) Supplementation on Placental and Fetal Intestinal Growth and Development in Sheep
(North Dakota State University, 2012)The placenta and fetal intestines are two key nutrient transport organs that sustain and nurture growing fetus. Insufficient placental development and consequently inadequate fetal nutrient supply can lead to IUGR resulting ... -
The Effects of Metabolizable Protein Intake and Post-Ruminal Flow of Amino Acids on Growth Performance and Pancreatic Digestive Enzymes in Steers
(North Dakota State University, 2018)Excessive dietary protein may affect MP use because of energetic costs of excreting excess N. Amino acids also may influence post-ruminal digestion. Therefore, two experiments were designed to evaluate the effects of MP ... -
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 ... -
Effects of Protein Supplement During the Last Third of Pregnancy on Blood Flow to the Mammary Gland in Beef Cows
(North Dakota State University, 2016)Calves born to cows fed a protein supplement during late pregnancy have greater production characteristics compared to calves from cows not supplemented, despite similar birth weights. Our hypothesis was that cows receiving ... -
The Effects of Sex, Breed, and Slaughter Weight on Growth, Carcass, and Sensory Characteristics of Lamb
(North Dakota State University, 2018)American lambs are often over-finished and lack consistent quality. It has been suggested that the use of intact ram lambs can decrease USDA YG and improve growth efficiency. However, ram lamb carcasses are underutilized ... -
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 ... -
Estimating the Impacts of Litter Size and Non-Additive Genetic Effects on Ewe Longevity and Stayability in a U.S. Western Extensive Range Production System
(North Dakota State University, 2021)Non-additive genetic effects are usually ignored in animal breeding programs due to data structure, computational limitations, and over-parameterization of the models. Non-additive genetic effects play an important role ... -
Evaluation of a Novel Means to Euthanize Piglets
(North Dakota State University, 2012)Research was conducted to evaluate a novel means to euthanize piglets utilizing electromagnetic energy. Experiment 1 assessed if electromagnetic energy could result in a euthanized piglet and Experiment 2 evaluated states ... -
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 ... -
Evaluation of Feedlot Cattle Health Relative to Carcass Quality
(North Dakota State University, 2010)The objective of this study was to investigate the effects of Bovine Respiratory Disease (BRD) and liver condemnation on beef carcass traits. Health treatment records for 2534 animals from a North Dakota feedlot were ... -
Evaluation of Glycated Albumin as a Metabolic Marker for Marbling in Commercial Feeder Cattle
(North Dakota State University, 2015)This study was conducted to determine if glycated albumin is associated with marbling in beef cattle. Crossbred steers (n=113) were assigned randomly to different treatments to determine the effects of feeding strategies ... -
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 ... -
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 ... -
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 ... -
