Ramped nursery housing of pigs and its effects on behavior during the nursery phase and during trailer loading and unloading at marketing
(North Dakota State University, 2024-07)Transportation, including semi-trailer loading and unloading, is known to stress pigs in commercial production. Therefore, strategies for reducing stress experienced by pigs during transportation are needed to reduce poor ... -
One-carbon metabolites, fetal growth, maternal oxidative stress, and fetal programming during early gestation
(North Dakota State University, 2024)In ruminant production systems, maternal nutrient intake and supplementation practices vary widely throughout the industry. Adequate maternal nutrient supply is critical for fetal development and subsequent offspring ... -
Dietary Impacts on Mitochondrial Respiration of Gestating Heifers and Fetal Offspring
(North Dakota State University, 2024)Two projects were conducted to evaluate dietary impacts on mitochondrial respiration of gestating heifers and fetal offspring. Our first hypothesis was that maternal vitamin and mineral supplementation during gestation ... -
Heat-treated Soybean Meal in Beef Cattle Diets
(North Dakota State University, 2024)Two experiments were conducted to evaluate replacing dried distillers grains with solubles (DDGS) with heat-treated soybean (TSBM) at increasing rates in forage-based diets on steer growth performance, nutrient flow, and ... -
The Impact of Media on Price Paid for Thoroughbred Horses at Auction
(North Dakota State University, 2024)It has been said a picture is worth a thousand words, but the economic value of that picture for livestock sales transactions has not been quantified. The objective of this study aimed to evaluate the effect of the presence ... -
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 ... -
Characterization of Salmonella spp. Isolated From Beef Cattle Post-Weaning To Slaughter
(North Dakota State University, 2010)The occurrence of Salmonella in cattle has been well documented, but little is known of tracking its prevalence and antimicrobial resistance (AMR) from postweaning to slaughter. This study follows a longitudinal approach, ... -
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 ... -
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 ... -
Genetic Predictions Using Subjective Methods of Beef Cattle Temperament Evaluation, Genetic Association Between Beef Cattle Temperament and Production Traits, and Influence of Sire and Dam Temperament on Calf Performance
(North Dakota State University, 2021)Beef cattle temperament is not only important to handler safety and animal welfare but also found to be related to productivity and thereby, considered an economically important trait. Constraints to improve cattle temperament ... -
Ancestral Breed Grouping for Improving Animal Modeling in Admixed Populations and Its Use in Leptin (Genetic and Hormone) Association Studies with Performance Traits in Commercial Beef Cow Herd
(North Dakota State University, 2021)The first study investigated American Aberdeen (AD) cattle's genetic structure and its genetic relationships with five American taurine beef breeds and the genetic population structure of a related admixed cattle herd for ... -
An Evaluation of Feeding Hempseed Cake in Finishing Cattle Diets
(North Dakota State University, 2022)Understanding the potential of hempseed cake to be used as a livestock feedstuff is important for both industrial hemp and beef producers. Experiment 1 evaluated the effects of hempseed cake (HEMP) on growth performance, ... -
Understanding Consumer Acceptance of Multiple Red Meat Products and Perceptions of the American Meat Science Association’s Intercollegiate Meat Judging Program Benefits From Participants
(North Dakota State University, 2022)Per capita consumption of red meat products totaled 67 kg in 2017. Given the popularity of meat, it is important for meat scientists to monitor consumers acceptance of red meat products. Consumer acceptance of red meat ... -
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 ... -
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 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 ... -
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 ... -
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 ... -
