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, ... -
Effects of Feeding 60% Dried Corn Distillers Grains Plus Solubles on Yearling Bull Reproduction
(North Dakota State University, 2020)Thirty-six half-sibling Angus bulls were assigned one of three diets: 1) 60% corn-based (CON; S = 0.18%; n = 12); 2) 60% DDGS replacing corn (60DDGS; S = 0.55% DM; n = 12); 3) CON diet + equivalent sulfur of 60DDGS added ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ...
