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 ... -
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 ... -
Supplemental Leucine in Milk Replacer Fed to Neonatal Calves and Lambs: Effects on Growth, Development, and Metabolism
(North Dakota State University, 2021)Maximizing growth during the neonatal period in preruminants can enhance long-term growth and productivity, increasing producer profits and input efficiency. Meeting the requirements for growth can be achieved through ... -
Understanding the Relationship Between Weather Variables, Dry Matter Intake, and Average Daily Gain of Beef Cattle
(North Dakota State University, 2021)The current National Academies of Sciences, Engineering and Medicine (NASEM) dry matter intake (DMI) prediction models are inadequate for DMI prediction of beef cattle in the Northern Great Plains. Four studies were conducted ... -
Maternal Nutrition, One-Carbon Metabolites, and Programming of Fetal Development During Early Gestation
(North Dakota State University, 2019)Crossbred Angus heifers (n = 14) were bred via AI, assigned to nutritional treatment (CON = 100% of requirements for 0.45 kg/d gain and RES = 60% of CON) and ovariohysterectomized on d 50 of gestation. Fetal liver, muscle ... -
Effects of Nutrient Restriction, Realimentation, and Twinning on Plasma Volume, Umbilical Hemodynamics and Placental Characteristics in the Pregnant Adolescent Ewe
(North Dakota State University, 2019)Reproductive physiology in production animals is a key economic component of longevity and profitability of animal farming. There are several components that can benefit or compromise adequate pregnancy periods. Sheep ... -
Energy and Mineral Supplementation Strategies for Beef Cattle Grazing the Northern Great Plains
(North Dakota State University, 2019)Four experiments were conducted to evaluate different technologies and supplementation strategies that may impact beef cattle production in the Northern Great Plains. Our overarching hypothesis was that we can enhance beef ... -
Factors Affecting Testicular Growth and Development in the Beef Bull
(North Dakota State University, 2019)At present no single parameter can predict potential daily sperm production (DSP) in bulls. Sertoli cells (SC) are responsible for nourishing and providing physical support to germ cells (GC) throughout spermatogenesis. ... -
Effects of Replacing Supplemental Sucrose with Beef During Mid to Late Gestation on Maternal Health and Fetal Growth and Development Using a Sow Biomedical Model
(North Dakota State University, 2019)Americans consume three percent more total daily calories from sugar than current recommendations. Maternal diets high in sugar can cause obesity and diabetes mellitus. Objectives were to compare supplemental dietary sucrose ... -
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 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 Impact of Digestive Enzymes in the Ruminant Animal
