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 ...
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 ...
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 ...
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 ...
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 ...
Examining the Potential of the GALR2 Genotype as a Marker-Assisted Management Strategy to Improve Production Efficiencies and Carcass Characteristics in Crossbred Angus Finishing Steers
(North Dakota State University, 2020)
The objective was to determine how the interaction of implant strategies with the galanin receptor 2 genotype would influence feeding behavior, production efficiencies, carcass characteristics, and meat quality in finishing ...
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 ...
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, ...
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 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 ...
