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 ... -
Factors Influencing the Passive, Innate, and Adaptive Immune System and Their Effects in Beef Cattle
(North Dakota State University, 2015)To investigate the factors influencing the passive, innate, and adaptive immune system and their effects in beef cattle, three experiments (exp.) were completed. Results from Exp. 1 indicate that there is some influence ... -
Impact of Environmental Factors on Ovarian Function and Endocrine Activity in Livestock
(North Dakota State University, 2013)Ovarian function is important in reproductive efficiency since the ovary is the site of oocyte development, as well as production and secretion of hormones necessary for proper follicle development, ovulation, and maintenance ... -
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 ... -
Impacts of Added Roughage on Feedlot Performance, Digestibility, Ruminal Fermentation, and Ruminal pH of Steers Fed Wheat-Based Feedlot Diets
(North Dakota State University, 2021)Two studies were conducted to evaluate the inclusion of additional roughage in wheat-based diets containing modified distillers’ grains with solubles on feedlot performance (Study 1) and digestibility, ruminal pH, and ... -
Impacts of Banamine Injection on Pain Responses of Either Rubber Ring Castrated and Tail Docked or Surgically Castrated and Docked Lambs
(North Dakota State University, 2020)Our hypothesis was that administering Flunixin Meglumine (FM) to lambs that were both rubber ring castrated and docked or surgically castrated and emasculator docked would decrease behavioral stress, serum cortisol, ... -
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 ... -
Impacts of Supplemental Arginine on Ewe Reproductive Performance
(North Dakota State University, 2014)The objective of this study was to determine the effects of injectable and oral arginine (Arg) supplementation provided 14 d post-breeding on reproductive performance of fall lambing ewes. Upon estrus detection (d 0) ewes ... -
The Influence of Beef Carcass Weight on Troponin-T Degradation and Heat Shock Protein 70 in Two Different Muscles
(North Dakota State University, 2021)This study was aimed to assess how carcass size affects protein degradation in postmortem muscle and subsequent impacts on meat quality. Beef carcasses were randomly selected at slaughter and classified as heavy (> 430.9 ... -
Influence of Maternal Nutrient Intake on Placental Vascular Function in Pregnant Beef Cows
(North Dakota State University, 2014)We hypothesized that global maternal nutrient restriction during early and mid-gestation followed by realimentation in pregnant beef cows would alter placental arterial vascular function. We tested changes in placental ... -
Influence of Maternal Nutrient Intake on Placental Vascular Function in Pregnant Beef Cows
(North Dakota State University, 2014)Two experiments investigating impacts of maternal nutrition in beef cows were conducted; 1) to test the impact of duration of global nutrient restriction and subsequent realimentation throughout gestation on placentome ... -
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 ... -
