Exploratory Evaluation Of Handler Performance And Processing-Related Outcomes During Cattle Handling, Morgan Marquardt

Department of Animal Science: Dissertations, Theses, and Student Research

Animals have several critical roles in society, including the production of food and fiber, and companionship. Contact with animals has been shown to benefit human physical and mental health, yet little research has investigated the impact that humans have on animals. Handler skill may considerably affect the extent to which humans influence animal health and wellbeing, and this may be a critical consideration for animal agriculture. Objective assessment of cattle handler skill has received limited attention in the scientific literature, despite its importance to human safety and animal welfare. When compared to less skilled handlers, highly skilled cattle handlers may …

Is Precision Agriculture Technology Adoption Persistently Overestimated?, Trey Malone, Chad Fiechter, Zanliang Meng, James Lowenberg‐Deboer, Bruce Erickson, Jay Akridge

Department of Agricultural Economics Faculty Publications

Precision agriculture is sometimes assumed to diffuse steadily over time, and industry planning frequently extrapolates early adoption trends forward. This study evaluates the accuracy of such expectations by comparing agricultural input dealers' forecasts of future service offerings with the actual levels of offerings that dealerships eventually provided. Using 21 waves of the CropLife-Purdue Precision Agriculture Dealership Survey from 2000 to 2025, we examine expected and realized precision agriculture offerings across 26 technologies. We document systematic and persistent overestimation of adoption: for most technologies, expected diffusion exceeds realized outcomes, with forecast errors becoming especially pronounced as adoption flattened or declined in …

From Niche To Norm: Plant-Based Labelling Strategies To Shift Social Norms To Support Plant-Based Food Choices, Houkje Adema, Marleen C. Onwezen, Ellen J. Van Loo, Liam Dwyer, Ellen Van Kleef

Department of Agricultural Economics Faculty Publications

Plant-based labels aim to promote plant-based choices by highlighting which products are plant-based. However, these labels are often applied selectively, leaving many more plant-based products unlabelled. We argue that this may unintentionally communicate that plant-based options are more ‘niche’ rather than the ‘norm’, and thereby hinder normalisation of plant-based consumption. Across two incentive-compatible experiments with representative Dutch samples in a simulated online supermarket, we examined how labelling interventions influence perceived availability of plant-based options, descriptive and injunctive social norms for choosing plant-based, and plant-based choices. In Study 1 (N = 1474), we manipulated the number of plant-based products labelled as …

Measurement And Control Of The Oxidation-Reduction Potential And Its Chemical And Sensory Consequences In Wines, William Jordan Wright

Master's Theses

The oxidation-reduction potential (ORP) is a measurement thought to reflect the overall ability of a solution to oxidize or reduce substances within that solution. In wine, there is no absolute agreement as to which substances control or dominate the ORP; however, oxygen, ethanol, iron-tartrate and copper-tartrate complexes, and glutathione are suspected to play key roles, while sulfur dioxide and phenolics may act as buffers. Anecdotally, some varieties of Vitis vinifera are prone to oxidation while others are prone to reduction, though the chemical basis of this remains unclear. The following works aim to further elucidate the influence of specific chemical …

Conditioned Feed Aversion As A Means Of Conditioning Livestock To Avoid Consuming Toxic Plants Growing In South Africa : An Overview, Leendert D. Snyman, Frederick D. Provenza

Poisonous Plant Research (PPR)

Significant economic losses to the livestock industry are caused by the ingestion of toxic plants in South Africa, among which the most dangerous ones are Moraea pallida (geeltulp), Urginea/Drimea sanguinea (rooislangkop), Senecio latifolius (Staggers Ragwort), and Geigeria ornativa (vermeerbos). Conditioned feed aversion is a potential means to address this issue. Treating animals with an aversive substance along with an extract of the sensory characteristics of a specific plant conditions animals to avoid the plant. Geigeria ornativa, unlike the other three plants, is non-aversive. Following treatment for aversion, the induced aversion fades with time and eventually breaks down. Continuous exposure …
