Understanding the Equine Distal Limb
(North Dakota State University, 2019)Studies examining health of the distal limb and lameness conditions are important for education and future research. It is hypothesized that changes to the external hoof would result in alterations to blood flow throughout ... -
Perceptions of Modern Meat-Animal Production from Consumers Two to Three Generations Removed from the Farm
(North Dakota State University, 2019)A consumer is defined as a person who purchases goods and services for personal use or a person or thing that eats or uses something (Merriam-Webster, 2019). Consumers either want or need to eat meat, whether it is for ... -
The Effects of Red Meat or Sugar Supplementation during Gestation and Lactation on Maternal Reproduction, Maternal and Offspring Blood Parameters, and Offspring Body Composition
(North Dakota State University, 2019)Using swine as a model for humans, this study was conducted to examine whether maternal consumption of added protein (red meat) or free sugar (glucose) throughout gestation and lactation was associated with maternal ... -
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 ... -
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 ... -
The Effects of Maternal Diet on Passive Transfer of Immunity to the Neonatal Beef Calf, and Calf Immune Response to Vaccination and Immunostimulants
(North Dakota State University, 2018)To investigate the effects of maternal diet on passive transfer of immunity to the neonatal beef calf, and calf immune response to vaccination and immunostimulants, three experiments (Exp.) were completed. Results from ... -
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, ... -
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 ... -
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 ... -
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 ... -
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 ... -
The Effect of Vitamin A Restriction on Marbling and Adipogenic Gene Expression in Commercial Angus and Simmental Steers
(North Dakota State University, 2017)Vitamin A (Vit-A) restriction has been shown to increase marbling in cattle. Our hypothesis for this study was that a low Vit-A diet would increase marbling and improve meat quality characteristics while having no effect ... -
The Use of Subjective and Objective Methods of Behavioral Evaluation in Swine and Dairy Cattle
(North Dakota State University, 2017)The objectives of the studies described in this thesis were to quantify livestock behavior and improve animal wellbeing. Subjective and objective evaluation methods can be used as an estimation parameter of animal welfare. ... -
The Effects of Feeding Seaweed Extract in the Diet of Swine on Gut Health, Performance, Carcass Characteristics, and Pork Quality
(North Dakota State University, 2017)Consumers are concerned about antibiotic and ractopamine usage; therefore, alternatives need to be found. Objectives of this study were to investigate the effects of using seaweed as an alternative feed supplement and ... -
Winter Feeding Strategies: Implications of Corn Supplementation on Gestating Beef Cows
(North Dakota State University, 2017)Overwintered, gestating beef cows fed low-quality forage are at risk of nutrient restriction which can lead to compromised growth and poor carcass quality in their offspring. In many species, poor maternal nutrition also ... -
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 ... -
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, ... -
Understanding the Role of Uterine Blood Flow on Offspring Development and Meat Quality in Swine
(North Dakota State University, 2017)Piglets that are born with low viability have increased mortality during early life, result in increased labor by personnel and potential animal welfare concerns. Producers focused on improving ovulation rates with the ... -
The Effects of Forage Level in Whole or Dry-Rolled Corn Based Diets on Carcass Characteristics, Meat Tenderness, and Meat Color
(North Dakota State University, 2016)The objective of this study was to determine if increasing the forage level and feeding grain whole as opposed to dry-rolled is a feasible alternative to high energy rations with a similar age at time of slaughter. Steers ... -
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 ...
