Factors Influencing the Passive, Innate, and Adaptive Immune System and Their Effects in Beef Cattle
(North Dakota State University, 2015)To investigate the factors influencing the passive, innate, and adaptive immune system and their effects in beef cattle, three experiments (exp.) were completed. Results from Exp. 1 indicate that there is some influence ... -
Heat-treated Soybean Meal in Beef Cattle Diets
(North Dakota State University, 2024)Two experiments were conducted to evaluate replacing dried distillers grains with solubles (DDGS) with heat-treated soybean (TSBM) at increasing rates in forage-based diets on steer growth performance, nutrient flow, and ... -
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 ... -
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 ... -
The Impact of Media on Price Paid for Thoroughbred Horses at Auction
(North Dakota State University, 2024)It has been said a picture is worth a thousand words, but the economic value of that picture for livestock sales transactions has not been quantified. The objective of this study aimed to evaluate the effect of the presence ... -
Impacts of Added Roughage on Feedlot Performance, Digestibility, Ruminal Fermentation, and Ruminal pH of Steers Fed Wheat-Based Feedlot Diets
(North Dakota State University, 2021)Two studies were conducted to evaluate the inclusion of additional roughage in wheat-based diets containing modified distillers’ grains with solubles on feedlot performance (Study 1) and digestibility, ruminal pH, and ... -
Impacts of Banamine Injection on Pain Responses of Either Rubber Ring Castrated and Tail Docked or Surgically Castrated and Docked Lambs
(North Dakota State University, 2020)Our hypothesis was that administering Flunixin Meglumine (FM) to lambs that were both rubber ring castrated and docked or surgically castrated and emasculator docked would decrease behavioral stress, serum cortisol, ... -
Impacts of Flax on Female and Male Reproductive Traits When Supplemented Prior to Breeding in Sheep
(North Dakota State University, 2018)Two experiments determined the effects of flaxseed supplementation on reproductive parameters in sheep. In experiment one, 240 multiparous Rambouillet ewes were assigned to one of two treatments: basal ration alone or basal ... -
Impacts of Supplemental Arginine on Ewe Reproductive Performance
(North Dakota State University, 2014)The objective of this study was to determine the effects of injectable and oral arginine (Arg) supplementation provided 14 d post-breeding on reproductive performance of fall lambing ewes. Upon estrus detection (d 0) ewes ... -
The Influence of Beef Carcass Weight on Troponin-T Degradation and Heat Shock Protein 70 in Two Different Muscles
(North Dakota State University, 2021)This study was aimed to assess how carcass size affects protein degradation in postmortem muscle and subsequent impacts on meat quality. Beef carcasses were randomly selected at slaughter and classified as heavy (> 430.9 ... -
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 ... -
Influence of Maternal Nutrient Intake on Placental Vascular Function in Pregnant Beef Cows
(North Dakota State University, 2014)Two experiments investigating impacts of maternal nutrition in beef cows were conducted; 1) to test the impact of duration of global nutrient restriction and subsequent realimentation throughout gestation on placentome ... -
Influence of Plasma Nuclear Magnetic Resonance Profile, Urea-Nitrogen, Glucose and Non-Esterified Fatty Acids on Dry Matter Intake in Developing Heifers and Mature Cows
(North Dakota State University, 2022)The objective of this experiment was to determine if nuclear magnetic resonance (NMR) profiles or blood metabolites could explain dry matter intake (DMI) in developing heifers and/or mature cows in the weeks leading to ... -
Management Considerations for Successful Technology Implementation in Beef Production Systems
(North Dakota State University, 2015)Two experiments were conducted to evaluate management strategies that foster successful implementation of technology in beef production systems. In experiment 1, cow reproductive performance, BW, and serum concentrations ... -
The Milk Withholding Time of Salicylic Acid for Treatment of Digital Dermatitis in Dairy Cattle
(North Dakota State University, 2020)Digital dermatitis is a top cause of lameness in dairy cattle that results in ulcerative lesions on the feet. Topical salicylic acid has been shown to provide similar efficacy to the antibiotic drugs used previously, but ... -
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 ... -
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 ... -
The Role of Distillers Dried Grains with Solubles in Sulfur Toxicity in Ruminants
(North Dakota State University, 2010)One of the challenges with using ethanol co-products is the potential for increased dietary S concentration. Dietary S concentration has been implicated as a cause of polioencephalomalacia (PEM) in ruminants. The focus ... -
Role of Lipotropic (Methyl) Nutrients on Mammary Development and Carcinogenesis in Female Rat Offspring
(North Dakota State University, 2015)Lipotropes (methionine, choline, folate, and vitamin B12) play a key role in one-carbon metabolism. We hypothesized that maternal methyl (lipotropic) nutrients would induce epigenetic modification that influences mammary ... -
The Role of Supplemental Beef vs. Sugar during Pregnancy on Fetal and Offspring Developmental Programming in Swine
(North Dakota State University, 2019)Sugar intake is linked to developmental programming of obesity and diabetes. We hypothesized that supplementing ground beef in place of sugar during pregnancy would reduce fetal and offspring developmental programming. ...
