Effects of Corn Condensed Distillers Solubles Supplementation on Intake, Performance, Rate and Site of Digestion, and Ruminal Fermentation in Cattle Consuming Forage-Based Diets
(North Dakota State University, 2015)Two studies were conducted to determine effect of feeding method and level of corn condensed distillers solubles supplementation on performance of beef cows fed forage-based diets and effects on digestibility and ruminal ... -
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. ... -
The Impact of Management Decisions and their Effect on Reproductive Performance of Beef Cattle
(North Dakota State University, 2014)Two experiments were conducted to evaluate two management decisions made by beef cattle producers and their impacts on reproduction. In experiment 1, growth, attainment of puberty, and pregnancy rates were evaluated in ... -
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 ... -
Effects of Dietary Supplementation of Flaxseed and Metabolizable Protein on Reproduction in Mares and Ewes
(North Dakota State University, 2014)Two experiments evaluated the effects of dietary supplementation on maternal reproductive parameters. In Experiment 1, 16 mares were assigned to dietary treatments: control, flaxseed, or linseed meal for 16 wk. Blood ... -
Effects of Distillers Dried Grains with Solubles Supplementation to Yearling Heifers Grazing Northern Great Plains Rangeland: Impacts on Subsequent Feedlot Performance and Meat Quality
(North Dakota State University, 2013)Eighty two yearling heifers (319.5 ± 1.03 kg) were utilized in a completely randomized design to evaluate the effects of distillers dried grains with solubles (DDGS) supplementation on animal performance while grazing on ... -
Impact of Environmental Factors on Ovarian Function and Endocrine Activity in Livestock
(North Dakota State University, 2013)Ovarian function is important in reproductive efficiency since the ovary is the site of oocyte development, as well as production and secretion of hormones necessary for proper follicle development, ovulation, and maintenance ... -
National Retail Pork Benchmarking Study: Characterizing Pork Quality Attributes of Multiple Cuts in the Self-serve Meat Case
(North Dakota State University, 2013)The objective of this study was to benchmark fresh pork quality in the retail meat case in the United States. Nationally, 117 retail supermarkets in 67 cities were selected for sampling. Center-cut loin chops were observed ... -
Influence of Maternal Nutrient Intake on Placental Vascular Function in Pregnant Beef Cows
(North Dakota State University, 2014)We hypothesized that global maternal nutrient restriction during early and mid-gestation followed by realimentation in pregnant beef cows would alter placental arterial vascular function. We tested changes in placental ... -
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, ... -
Effects of Alternate Day Feeding of Dried Distiller’s Grains Plus Solubles and Grass Hay on Metabolism and Performance in Cattle
(North Dakota State University, 2012)Two studies were conducted to determine the effects of supplementing dried distiller's grains plus solubles (DDGS) on alternate days to forage-fed cattle. We hypothesized that feeding either DDGS at a low percent of body ... -
Efficacy of Various Five-Day Estrous Synchronization Protocols in Sheep
(North Dakota State University, 2012)The objective of this study was to determine the effects of various estrous synchronization protocols utilizing the five-day controlled internal drug releasing (CIDR) inserts that are infused with progesterone (P4) alone ... -
Evaluation of a Novel Means to Euthanize Piglets
(North Dakota State University, 2012)Research was conducted to evaluate a novel means to euthanize piglets utilizing electromagnetic energy. Experiment 1 assessed if electromagnetic energy could result in a euthanized piglet and Experiment 2 evaluated states ... -
Effect of Maternal Metabolizable Protein Supplementation During Late Gestation on Fetal Visceralorgan Weight with Application of Proteomics to Investigate Skeletal Muscle Development in Sheep
(North Dakota State University, 2012)The experiment investigated supplementation of maternal metabolizable protein in an isocaloric diet during late gestation on fetal organ growth and skeletal muscle development in sheep. Although fetal body weight was ... -
The Relationship between Pre-Harvest Stress and Carcass Characteristics and the Ability to Qualify for Kosher on Beef Steers and Heifers
(North Dakota State University, 2013)The objective of this study was to determine if there is a difference in pre-harvest stress and carcass characteristics between kosher and not-qualified-as kosher cattle. Cattle that had a shorter time from gate to ... -
Effects of Maternal Nutrition, Intrauterine Growth Restriction (IUGR), and Estrogen (E2) Supplementation on Placental and Fetal Intestinal Growth and Development in Sheep
(North Dakota State University, 2012)The placenta and fetal intestines are two key nutrient transport organs that sustain and nurture growing fetus. Insufficient placental development and consequently inadequate fetal nutrient supply can lead to IUGR resulting ...
