Utilizing Behavioral Monitoring To Detect Sickness Or Injury In Dairy Cow And Calves, Nicole Louise Eberhart

Masters Theses

Cattle experience behavioral changes during incidences of discomfort such as respiratory disease, hock injuries, and lameness. Visual evaluation of these conditions, particularly lameness and respiratory disease can be subjective and may lead to untreated animals, which reduces the overall well-being of the animals. In order to improve detection of affected cattle, continuous or combined monitoring systems should be used. These technologies may improve detection compared to visual assessment by reducing human bias. Behavioral changes in particular may be detected through these means, with changes indicating potential health abnormalities in the individual cattle. One such behavior that changes during incidences of …

Evaluation Of Long-Acting Eprinomectin Compared To Conventional Anthelmintics In Cow/Calf Production, Elizabeth Ann Backes

Graduate Theses and Dissertations

Experiment 1, 83, newly weaned, fall-born crossbred heifer calves were allocated randomly to 1 of 3 anthelmintic treatments: 1) control (CON); 2) combination pour-on moxidectin and oxfendazole (MO); and 3) long-acting eprinomectin (LAE). Two preplanned orthogonal contrast statements were used: 1) to compare CON to treated cattle; and 2) to compare OXF to LAE. Heifer BW and BCS were greater (P≤0.02) from MO and LAE on d 112, 140, 154, 168, 182 compared to CON. Heifer cyclicity, estrous detection, natural service and overall pregnancy rates were greater (P≤0.02) for MO and LAE compared to CON. Cattle fecal egg counts (FEC) …

Psychology Faculty Publications

On April 14th, 2016, Animal Behavior and Cognition lost its Editor-in-Chief. But the scientific community and the friends and colleagues of Stanley ‘Stan’ Kuczaj III lost so much more. As many know, Stan began his career in Developmental Psychology, making enormous contributions in the area of language development, but became best known for his many innovative contributions in the area of marine mammal behavior. Stan founded Animal Behavior and Cognition because he was deeply passionate about research with a broad range of topics concerning animal behavior, animal cognition, and animal welfare. He was equally passionate about the idea that science …

Insulin-Dependent Glucose Metabolism In Dairy Cows With Variable Fat Mobilization Around Calving, C. Weber, C. T. Schäff, U. Kautzsch, S. Börner, S. Erdmann, S. Görs, M. Röntgen, H. Sauerwein, R. M. Bruckmaier, C. C. Metges, B. Kuhla, H. M. Hammon

Physiology Collection

Dairy cows undergo significant metabolic and endocrine changes during the transition from pregnancy to lactation, and impaired insulin action influences nutrient partitioning toward the fetus and the mammary gland. Because impaired insulin action during transition is thought to be related to elevated body condition and body fat mobilization, we hypothesized that over-conditioned cows with excessive body fat mobilization around calving may have impaired insulin metabolism compared with cows with low fat mobilization. Nineteen dairy cows were grouped according to their average concentration of total liver fat (LFC) after calving in low [LLFC; LFC <24% total fat/dry matter (DM); n = 9] and high (HLFC; LFC >24.4% total fat/DM; n = 10) fat-mobilizing …

Establishing A Link Between Personality And Social Rank In A Group Of Bottlenose Dolphins (Tursiops Truncatus), Erin Elizabeth Frick

Master's Theses

Bottlenose dolphins (Tursiops truncatus) have been documented to possess personality traits that remain consistent over time (Highfill & Kuczaj, 2007) and across contexts (Kuczaj, Highfill, & Byerly, 2012). Such individual differences are thought to play an important role in various social contexts such as hierarchical dominance (Highfill & Kuczaj, 2010). The present study investigated the relationship between personality and social rank within a captive group of bottlenose dolphins housed at the Roatan Institute for Marine Science (RIMS). Social rank was established using questionnaires distributed to the RIMS experienced staff. Personality traits were derived from behavioral coding using context-specific …

The Effect Of Auditory Stimulation On Sleep Disruption In West Indian Manatee (Trichechus Manatus Latirostris), Natalija Lace

Dissertations

Florida manatees inhabit waterways where motorized boats are common. Although manatee mortalities resulting from boat strikes are well documented, the effect of boat noise on some manatee behaviors, including rest, has not been investigated. This study focuses on rest behavior and used a playback experiment with four manatees at the Lowry Park Zoo in Florida. We tested their responses to playback stimuli of either boat noise, silence, or manatee calls. A playback trial was initiated when the focal animal showed behavioral characteristics of rest.

Results showed that rest was interrupted in response to the playback of boat noise for each …

Short-Beaked Common Dolphin (Delphinus Delphis) Occurrence In The Moray Firth, North-East Scotland, Kevin P. Robinson, Sonja Eisfeld, Marina Costa, Mark P. Simmonds

Mark P. Simmonds, OBE

The short-beaked common dolphin (Delphinus delphis) is regarded as notably rare or absent from the northern North Sea, but recent evidence suggests a rising frequency of the species in these waters with increasing regional sea temperatures. The following paper documents the presence of D. delphis in the Moray Firth in north-east Scotland and provides the first evidence for the sustained occurrence of these delphinids in this region during the warmer summer months at least. Sightings were collated during systematic surveys of the outer Moray Firth between 2001 and 2009 by independent research teams from the CRRU and WDCS. A total …

Behavior Of A Solitary Sociable Female Bottlenose Dolphin (Tursiops Truncatus) Off The Coast Of Kent, Southeast England, Sonja Eisfeld, Mark P. Simmonds, Laura R. Stansfield

Mark P. Simmonds, OBE

This article provides a report of the behavior of a solitary sociable dolphin studied on the southeast coast of England in 2007. This is the first study of its kind in which behavior of such a nonhuman animal was systematically studied. By the time of this study, this young female was highly interactive with people in the water. People accompanied the dolphin for 18.4% of the 100 hr of observation, and their presence changed her behavior. The study recorded 39 different behaviors; feeding and resting behaviors declined in frequency in the presence of people. In addition, the dolphin exhibited behavior …

Changes In Tursiops Truncatus Distribution And Behavior In The Drowned Cayes, Belize, And Correlation To Human Impacts, Jazmin Garcia

HCNSO Student Theses and Dissertations

Human interaction greatly influences the behavior and distribution of bottlenose dolphins (Tursiops truncatus). This project focuses on the distribution and behavior of bottlenose dolphins in the Drowned Cayes, Belize. Prior to the 2000s, the area was relatively undeveloped and undisturbed and had minimal human activity. Since the turn of the millennium, development and ecotourism activity has flourished in the area, increasing by more than 800,000 visitors from 1998-2006. Boat-based surveys were conducted in 2015 and were combined with previous survey data collected from 2005-2012 and compared to behavioral survey results from 1999-2000. Total dolphin observation time as a …

Culture, Reform Politics, And Future Directions: A Review Of China’S Animal Protection Challenge, Peter J. Li, Gareth Davey

Peter J. Li, PhD

Incidents of animal abuse in China attract worldwide media attention. Is China culturally inclined to animal cruelty, or is the country’s development strategy a better explanation? This article addresses the subject of animal protection in China, a topic that has been ignored for too long by Western China specialists. A review of ancient Chinese thought asks whether China lacks a legacy of compassion for animals. The article then considers how China’s reform politics underlie the animal welfare crisis. Through its discussion of the welfare crisis impacting nonhuman animals in China, this paper sheds light on the enormity of the country’s …

Enforcing Wildlife Protection In China, Peter J. Li

Peter J. Li, PhD

Since China enacted the Wildlife Protection Law in 1988, its wildlife has been threatened with the most serious survival crisis. In the prereform era, wildlife was a neglected policy area. Serving the objective of reform, the Wildlife Protection Law upholds the “protection, domestication, and utilization” norm inherited from past policies. It establishes rules for wildlife management and protection. This law provides for penalties against violations. Yet, its ambiguous objectives, limited protection scope, and decentralized responsibilities have made its enforcement difficult. Political factors such as institutional constraints, national obsession with economic growth, shortage of funding, and local protectionism have made the …

Exponential Growth, Animal Welfare, Environmental And Food Safety Impact: The Case Of China’S Livestock Production, Peter J. Li

Peter J. Li, PhD

Developmental states are criticized for rapid “industrialization without enlightenment.” In the last 30 years, China’s breathtaking growth has been achieved at a high environmental and food safety cost. This article, utilizing a recent survey of China’s livestock industry, illustrates the initiating role of China’s developmental state in the exponential expansion of the country’s livestock production. The enthusiastic response of the livestock industry to the many state policy incentives has made China the world’s biggest animal farming nation. Shortage of meat and dairy supply is history. Yet, the Chinese government is facing new challenges of no less a threat to political …

Animals Are Agents, Linda A.W. Brakel

Animal Sentience

Mark Rowlands’s (2016) target article invites us to consider individuals in a broad subset of the non-human animal world as genuine persons. His account features animals reacting to salient environmental stimuli as Gibsonian affordances, which is indicative of “pre-reflective self-awareness.” He holds that such pre-reflective self-awareness is both “immune to error through misidentification” (Shoemaker, 1968) and a necessary precursor to reflective consciousness and personhood. I agree. In this commentary I hope to extend Rowlands’s work with a view in which agency is an even more fundamental precursor and one can (and should) consider individuals throughout the entire animal kingdom as …

Japanese Small Type Coastal Whaling, Sue Fisher

Commercial Whaling Collection

2016 marks the 70th anniversary of the International Convention for the Regulation of Whaling (ICRW) as well as the 30th anniversary of the International Whaling Commission’s (IWC) moratorium on commercial whaling. It also marks three decades of effort by Japan to overturn this ban. Its strategy to circumvent the moratorium by issuing permits to kill protected whales for scientific research is famous—even the subject of a 2014 lawsuit at the International Court of Justice. Less well known is Japan’s strategy to overturn the ban by persuading the Commission to authorize a category of commercial whaling known as Small Type Coastal …

Toxicity Testing In The 21st Century: A Vision And A Strategy, Daniel Krewski, Daniel Acosta Jr, Melvin Anderson, Henry Anderson, John C.

Martin Stephens, PhD

With the release of the landmark report Toxicity Testing in the 21st Century: A Vision and a Strategy, the U.S. National Academy of Sciences, in 2007, precipitated a major change in the way toxicity testing is conducted. It envisions increased efficiency in toxicity testing and decreased animal usage by transitioning from current expensive and lengthy in vivo testing with qualitative endpoints to in vitro toxicity pathway assays on human cells or cell lines using robotic high-throughput screening with mechanistic quantitative parameters. Risk assessment in the exposed human population would focus on avoiding significant perturbations in these toxicity pathways. Computational systems …
