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; ...
2015 National Pork Retail Benchmarking Study
(North Dakota State University, 2016)
The objective of this study was to quantify pork quality variation in the retail self-serve meat case nationwide. Center-cut loin chops (CCLC) (n=3795) were analyzed in-store for subjective color and marbling scores (2.85 ...
Does Beef Inclusion in a Modern American Diet Influence Risk Factors for Obesity-related Metabolic Disorders via a Swine Biomedical Model
(North Dakota State University, 2016)
Using swine as a model for humans, this study was conducted to determine if replacing the sugar present in the average American diet (SUG) with ground beef (GB) would alter developmental body composition, onset of puberty, ...
The Exploration of a Four-Platform Standing Scale in the Application of Measuring Temperament in Beef Cattle
(North Dakota State University, 2016)
To assess the validity of a four-platform standing scale (FPSS) to measure cattle
temperament, calves were evaluated at weaning age with an objective four-platform standing
scale (FPSS) and subjective methods of docility ...
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 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 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 ...
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 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 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 ...
