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. ... -
Supplementation of Corn Dried Distiller's Grains Plus Solubles to Gestating Beef Cows Fed Low-Quality Forage
(North Dakota State University, 2015)To investigate the effects of corn dried distiller’s grains plus solubles (DDGS) supplementation to cows during late gestation, 27 multiparous beef cows were divided randomly into 2 treatment groups (CON; n = 15; SUP = ... -
Temperament Evaluation in Beef Cattle: Understanding Evaluator Bias Within Subjective Measurements of Docility Score, Temperament Score, and Qualitative Behavior Assessment
(North Dakota State University, 2016)An experiment was conducted to quantify evaluator bias and determine the impacts bias may have on genetic evaluations. Three subjective evaluation methods were recorded (n = 806) at weaning, including docility score (DS; ... -
Tenderness and Juiciness of Beef Steaks from Varying Hot Carcass Weights
(North Dakota State University, 2019)The objective of this study was to determine how hot carcass weights affect temperature decline and pH decline of beef carcasses, as well as, tenderness, juiciness and color of beef steaks. Carcasses were selected based ... -
Understanding the Role of Uterine Blood Flow on Offspring Development and Meat Quality in Swine
(North Dakota State University, 2017)Piglets that are born with low viability have increased mortality during early life, result in increased labor by personnel and potential animal welfare concerns. Producers focused on improving ovulation rates with the ... -
The Use of Behavioral Measures to Quantify Welfare in Dairy Cows and Lambs
(North Dakota State University, 2014)The primary objective of the experiments described in this thesis was to use quantitative behavioral measures of livestock to evaluate animal welfare. In one study, the effects of a therapeutic drug in lame dairy cows were ... -
Use of Soybean Hulls in Drylot Cow-Calf Diets
(North Dakota State University, 2021)One hundred and twenty-one Red Angus beef cows were used to evaluate the effects ofsoybean hull inclusion in drylot beef cow diets. Cows were stratified by age, body weight (BW),and body condition score (BCS), and randomly ... -
The Use of Subjective and Objective Methods of Behavioral Evaluation in Swine and Dairy Cattle
(North Dakota State University, 2017)The objectives of the studies described in this thesis were to quantify livestock behavior and improve animal wellbeing. Subjective and objective evaluation methods can be used as an estimation parameter of animal welfare. ... -
Winter Feeding Strategies: Implications of Corn Supplementation on Gestating Beef Cows
(North Dakota State University, 2017)Overwintered, gestating beef cows fed low-quality forage are at risk of nutrient restriction which can lead to compromised growth and poor carcass quality in their offspring. In many species, poor maternal nutrition also ...
