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 ... -
The Effects of Estrus on Dry Matter Intake and Feeding Behavior in Beef Heifers of Divergent Sizes
(North Dakota State University, 2020)The biological process of estrus in cattle is known to initiate behavioral responses as a result of fluctuations in hormones, which may alter time budgeted for feeding. The current study aimed to quantify these variations ... -
Effects of Feeding 60% Dried Corn Distillers Grains Plus Solubles on Yearling Bull Reproduction
(North Dakota State University, 2020)Thirty-six half-sibling Angus bulls were assigned one of three diets: 1) 60% corn-based (CON; S = 0.18%; n = 12); 2) 60% DDGS replacing corn (60DDGS; S = 0.55% DM; n = 12); 3) CON diet + equivalent sulfur of 60DDGS added ... -
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 ... -
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 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 ... -
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 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, ... -
The Effects of Late Gestational Exercise on Colostrum Quality and Neonatal Immunoglobulin Absorption
(North Dakota State University, 2021)To investigate the effects that late gestational exercise has on ewe performance and colostrum IgG levels, and to evaluate how it impacts neonatal serum IgG absorption and future performance, thirty-two multiparous Dorset ... -
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 ... -
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, ... -
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 ... -
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 ... -
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 ... -
Effects of Protein Supplement During the Last Third of Pregnancy on Blood Flow to the Mammary Gland in Beef Cows
(North Dakota State University, 2016)Calves born to cows fed a protein supplement during late pregnancy have greater production characteristics compared to calves from cows not supplemented, despite similar birth weights. Our hypothesis was that cows receiving ... -
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 ... -
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 ... -
Estimating the Impacts of Litter Size and Non-Additive Genetic Effects on Ewe Longevity and Stayability in a U.S. Western Extensive Range Production System
(North Dakota State University, 2021)Non-additive genetic effects are usually ignored in animal breeding programs due to data structure, computational limitations, and over-parameterization of the models. Non-additive genetic effects play an important role ... -
