2015 National Pork Retail Benchmarking Study
(North Dakota State University, 2016)The objective of this study was to quantify pork quality variation in the retail self-serve meat case nationwide. Center-cut loin chops (CCLC) (n=3795) were analyzed in-store for subjective color and marbling scores (2.85 ... -
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 ... -
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 ... -
Arginine Supplementation Strategies during Gestation: Impacts on Dams and Offspring
(North Dakota State University, 2015)We hypothesize rumen-protected arginine supplementation during gestation will mitigate deleterious offspring effects caused by undernutrition. Experiment 1: non-pregnant ewes were supplemented with rumen-protected arginine ... -
Biological Abnormalities in the Ruminant Small Intestine and Its Relationship to Carbohydrate Assimilation
(North Dakota State University, 2019)Several biological abnormalities exist between the ruminant and nonruminant small intestine and influences carbohydrate assimilation. Two experiments were conducted to identify potential mechanisms to improve carbohydrate ... -
Biological Evaluation of the Associations Between Animal Size, Feeding Behavior, Blood Metabolites and Feed Efficiency in Beef Cattle
(North Dakota State University, 2017)The biological variation in feed efficiency is regulated by multiple physiological mechanisms relevant to energy use in livestock species. The current study examined the associations between body composition, feeding ... -
Body Weight and Adiposity Changes of Obese Gilts Provided Ad Libitum Ground Beef Versus High Carbohydrate Diets
(North Dakota State University, 2014)This study investigated the impact of providing a red meat (GB; cooked ground beef; 63% lean) or high-carbohydrate diet (CON) on growth performance and body composition of obese gilts as a biomedical model for humans. ... -
Can Hematocrit Levels at Estrus in Dairy Cows and Sheep Be an Indicator for Pregnancy Success?
(North Dakota State University, 2019)Despite the major reproductive advances in the livestock industry, prenatal embryonic loss is still one of the major issues that causes substantial economic loss. While there are many tests available to determine pregnancy ... -
Characteristics of Health Parameters and the Digital Cushion in Horses
(North Dakota State University, 2015)Studies examining lameness conditions and health concerns for horse owners are important for education and future research. To investigate this, a survey and two studies were conducted. For the survey, a total of 152 ... -
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, ... -
Circulating Risk Factors for Obesity-Related Metabolic Disorders Associated with a Low-Glycemic Beef Diet Fed via a Swine Biomedical Model
(North Dakota State University, 2014)This study was conducted to determine if differences in blood chemistry are associated with a high fat ground beef diet. Ten crossbred gilts were allocated to a red meat (GB; cooked ground beef; 60% lean) or high-carbohydrate ... -
Computer Vision System as a Tool to Estimate Pork Marbling
(North Dakota State University, 2017)Currently pork marbling is assessed subjectively in the industry, because of the limited methods and tools that are suitable for the industry. In this dissertation, we are devoted to develop a computer vision system for ... -
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 ... -
Disseminating Agriculture Information using the BBQ Boot Camp Model
(North Dakota State University, 2017)The BBQ Boot Camp program was designed to educate consumers about agriculture production and sustainability, while teaching outdoor cooking methods with meat as the focus. Through the BBQ Boot Camp model, consumer impact ... -
Does Beef Inclusion in a Modern American Diet Influence Risk Factors for Obesity-related Metabolic Disorders via a Swine Biomedical Model
(North Dakota State University, 2016)Using swine as a model for humans, this study was conducted to determine if replacing the sugar present in the average American diet (SUG) with ground beef (GB) would alter developmental body composition, onset of puberty, ... -
The Effect of Artificial Insemination or Natural Service Breeding Systems on Reproductive Performance, Calving Characteristics, Weaning Characteristics, and Steer Backgrounding Performance in a Commercial Beef Herd
(North Dakota State University, 2013)Two experiments were conducted to evaluate the effects of beef cattle breeding systems that incorporate artificial insemination (AI) or breeding systems that use natural service mating on resultant reproductive performance, ... -
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 ... -
Effect of Linseed Meal on the Reproductive and Digestive Tracts in Sheep
(North Dakota State University, 2007)To evaluate the estrogenic potential of secoisolariciresinol diglycoside (SDG) found in linseed meal (LSM) on visceral organ mass, uterine mass, jejunal cellularity, jejunal vascularity, and angiogenic factor expression ... -
