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 ...
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 ...
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 ...
Effects of Maternal Nutrition During Gestation on Viscera Energy Use in Ruminant Dams and Offspring and Hypothalamic Neurohormone Content in the Offspring
(North Dakota State University, 2015)
The extensive use of grazing systems for ruminant livestock and the high variation in forage quality throughout the year have important impacts on production. Changes in feed quality and availability cause alteration in ...
Reproductive and Nutritional Impacts of Dried Distiller's Grains with Solubles on Growing Rams and Feedlot Lambs
(North Dakota State University, 2017)
Byproduct supplementation in livestock rations is viable and can lead to increased returns to producers. Increasing the inclusion of dried distiller’s grains with solubles (DDGS) was hypothesized to increase growth performance ...
The Role of Maternal Protein Intake During Late Gestation on Placental Vascular Function
(North Dakota State University, 2013)
Global nutrient restriction or excess can influence umbilical hemodynamics in sheep fetuses (Chapter 2). We hypothesized that a specific component of the diet, namely maternal metabolizable protein (MP), would alter placental ...
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 ...
Genetic Markers, Cattle Disposition, and Stress Relative to Variations in Beef Tenderness
(North Dakota State University, 2012)
The objective of this research was to evaluate the efficacy of genetic markers, disposition, and animal stress on variations in beef tenderness. Warner-Bratzler shear force (WBSF) values on 570 mixed breed heifers and ...
Influence of Cut, Cooking Method, and Post-Mortem Aging on Beef Palatability
(North Dakota State University, 2013)
The objectives of these studies were to determine the effects of cut, cooking method, and postmortem aging on improving consumers' perception of beef. Consumers evaluated bottom round, top sirloin, ribeye, and a value cut ...
The Impact of Reproductive Technologies on Beef Cattle and Management
(North Dakota State University, 2016)
Two experiments were conducted to evaluate producer management decisions that may impact beef cattle reproductive efficiency. The over-arching hypothesis was that critical breeding management decisions would positively ...
