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 ... -
Temperament Evaluation in Beef Cattle: Understanding Evaluator Bias Within Subjective Measurements of Docility Score, Temperament Score, and Qualitative Behavior Assessment
(North Dakota State University, 2016)An experiment was conducted to quantify evaluator bias and determine the impacts bias may have on genetic evaluations. Three subjective evaluation methods were recorded (n = 806) at weaning, including docility score (DS; ... -
Effects of Implanting Strategy and Zilpaterol Hydrochloride on the Calpain Proteolytic System in Sectioned Beef Steaks for Two Time Periods
(North Dakota State University, 2016)The objective of this study was to evaluate the impact of an anabolic implant and its use with the beta-adrenergic agonist zilpaterol hydrochloride (ZH) the calpain proteolytic system activity across specific areas of the ... -
The Impact of Digestive Enzymes in the Ruminant Animal
(North Dakota State University, 2016)Understanding the enzymatic activity in ruminant digestive systems is essential for securing adequate growth, reproduction and overall metabolism. In order to evaluate the impact of various nutritional sources and dietary ... -
Maternal Nutritional Plane and Endogenous Retroviral Gene Elements, Pregnancy Hormones, and Placental Vascularity and Angiogenic Factors during the Establishment of Pregnancy in Beef Cattle
(North Dakota State University, 2016)In order to meet the projected food demands by 2050, animal agriculture must increase production of animal products on the same or decreased land area through increased efficiency. Early gestation is one area to increase ... -
Effects of Grain Type and Oil Concentration of Corn Dried Distillers Grains Plus Solubles of Digestion, Finishing Performance, and Carcass Quality
(North Dakota State University, 2016)Changes in ethanol processing have resulted in a reduction of oil in the final coproduct, DDGS, available as a feedstuff. Lowering the oil concentration can decrease the total energy in the diet and, therefore, could affect ...
