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, ... -
The Effect of Hemp Byproduct Supplementation on Beef Quality
(North Dakota State University, 2022)The supplementation of hempseed cake (hemp byproduct) could be considered an alternative protein and fiber source for ruminants such as cattle. Hempseed cake might be a successful alternative feed source due to cattle’s ... -
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 ... -
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 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 ... -
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 ... -
The Effects of Arginine on Reproductive Performance in Ewes
(North Dakota State University, 2010)Reproductive performance is the largest determinant of income in the livestock industry. In the U.S. sheep industry, embryonic and fetal deaths during pregnancy account for almost half of the total number of fertilized ... -
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 ... -
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 ... -
