Trends In “Natural” Value-Added Calf Programs At Superior Livestock Video Auction, K. G. Odde, M. E. King, E. D. McCabe, M. J. Smith, K. L. Hill, G. M. Rogers, K. E. Fike 2019 Kansas State University, Manhattan

Trends In “Natural” Value-Added Calf Programs At Superior Livestock Video Auction, K. G. Odde, M. E. King, E. D. Mccabe, M. J. Smith, K. L. Hill, G. M. Rogers, K. E. Fike

Kansas Agricultural Experiment Station Research Reports

Objective: This study utilized data from Superior Livestock Video Auction to investigate trends in the use of “natural” value-added calf programs.

Study Description: Nine years of data (2010-2018) were evaluated for enrollment trends in all natural programs and non-hormone treated cattle. Multiple regression was used to determine the relative value of calves enrolled in the non-hormone treated cattle program.

The Bottom Line: Price advantages for non-hormone treated calves may not be sufficient to justify not using growth-promoting implants on calves.

Impact Of Shade On Performance And Heat Stress Of Finishing Cattle And Pooled Analysis Of Individually Fed Finishing Trials, Brett A. Melton

Theses and Dissertations in Animal Science

A commercial feedyard trial in Eastern Nebraska evaluated the effect of shade vs no shade on cattle performance, ear temperature, and panting scores. No differences in overall performance (final BW, DMI, ADG, and G:F) or carcass characteristics (HCW, 12th rib fat thickness, marbling, LM area, and calculated YG) were observed. Cattle that were provided shade had lower panting scores and ear temperatures, and greater DMI, compared to cattle that had no shade during heat events. Also, a treatment by hour interaction for movement of cattle occurred for one of the heat events. In comparison, the cool event had ...

U.S. Consumers’ Perception, Intention, And Purchase Behavior Of Grass-Fed Beef, Elizabeth K. Crandall

All Graduate Theses and Dissertations

The purpose of this research study was to compile regional profiles of the consumers who intend to consume grass-fed beef in the U.S. and to create marketing strategies that would assist producers in marketing their product to consumers. The researcher sent an online survey to a panel of 484 consumers across the U.S. to learn about their perceptions of and intention to purchase grass-fed beef.

Respondents had a weak, positive attitude toward purchasing grass-fed beef but had low knowledge of production practices. These consumers had a desire to eat healthier; however, they wanted meat that was priced right ...


Investigation Of Bacterial Taxa As Biomarkers Of Fescue Toxicosis And Heat Stress In Grazing Beef Cows, Sarah Katherine Chewning 2018 University of Arkansas, Fayetteville

Investigation Of Bacterial Taxa As Biomarkers Of Fescue Toxicosis And Heat Stress In Grazing Beef Cows, Sarah Katherine Chewning

Theses and Dissertations

Fescue toxicosis in grazing beef cattle is caused by consumption of Ergot alkaloids associated with tall fescue (toxic fescue) and is responsible for substantial economic loss to the U.S. beef industry. Cattle consuming toxic fescue suffer adverse physiological responses, such as: hyperthermia, increased respiration rate (RR), poor reproduction and growth performance. Other adverse responses to fescue toxins include the retention of a winter hair coat and vasoconstriction in the extremities, which can lead to tissue necrosis. Identifying cattle with reduced susceptibility to fescue toxins would allow for efficient use of fescue pastures; thus, the objectives of this thesis was ...


Effect Of Yeast Supplementation During Various Stages Of Beef Production, Elizabeth Palmer 2018 University of Arkansas, Fayetteville

Effect Of Yeast Supplementation During Various Stages Of Beef Production, Elizabeth Palmer

Theses and Dissertations

Supplemental dietary yeast products are beneficial during times of stress. Calves experience increased levels of stress during birth, weaning, and the post-weaning receiving period. Therefore, 3 experiments were conducted to determine how yeast supplementation affects growth performance and health during this time. In experiment 1, 2 truckloads of highly stressed calves (n = 175; initial body weight [BW] = 226 ± 24.5 kg) were assigned randomly to 1 of 3 treatments; unsupplemented control, or supplementation with 2 commercial yeast products (Y1 and Y2). Average daily gain (ADG) was not different (P = 0.99) during the 28 d receiving period; nor was there ...


Effect Of Tannin-Containing Legume Hays On Enteric Methane Emissions And Nitrogen Partitioning In Beef Cattle, Elizabeth K. Stewart 2018 Utah State University

Effect Of Tannin-Containing Legume Hays On Enteric Methane Emissions And Nitrogen Partitioning In Beef Cattle, Elizabeth K. Stewart

All Graduate Theses and Dissertations

Cattle are responsible for greenhouse gas emissions such as carbon dioxide, methane and nitrous oxide. In particular, the cow-calf phase of production accounts for approximately 80 percent of the total beef production system greenhouse gas emissions. Tannins are chemical compounds found in certain forages and they have the potential to help reduce these negative environmental impacts. Thus, given that the cow-calf phase often relies on feeding hay, feeding tannin-containing hays may represent a significant mitigation practice.

With my MS program, I sought to explore whether tannin-containing hays fed to mother cows and heifers influence methane and nitrogen emissions relative to ...


Identifying Breed Effects For Cow Mature Weight, Madeline J. Zimmermann 2018 University of Nebraska-Lincoln

Identifying Breed Effects For Cow Mature Weight, Madeline J. Zimmermann

Theses and Dissertations in Animal Science

Mature weight (MWT) in beef cattle has increased over the past 30 yr. In general, larger cows are costlier to maintain than smaller cows, and their profitability depends on their production environment. A wide range of beef production environments exist in the United States. There are also a variety of beef cattle breeds that can be chosen and mated to create a type of cow which will be optimally suited to excel in a given environment. However, there remains a need for tools allowing effective comparison among breeds to facilitate such decision making. Unfortunately, estimated progeny differences (EPD) for MWT ...


Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender 2018 Fordham University

Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender

Student Theses 2015-Present

This paper aims to shed light on the dissonance caused by the superimposition of Dominant Human Systems on Natural Systems. I highlight the synthetic nature of Dominant Human Systems as egoic and linguistic phenomenon manufactured by a mere portion of the human population, which renders them inherently oppressive unto peoples and landscapes whose wisdom were barred from the design process. In pursuing a radical pragmatic approach to mending the simultaneous oppression and destruction of the human being and the earth, I highlight the necessity of minimizing entropic chaos caused by excess energy expenditure, an essential feature of systems that aim ...
