Using Thermal Camera Drones In Beef Cattle Roundup, Justin Wyatt Clawson, Eric Galloway, Shalyn Drake, Shawn Barstow, Ross Israelsen, Michael Pate

All Current Publications

Using drones with thermal sensors can be an effective tool in finding and collecting livestock from summer mountain ranges in the West. Drones can complete searches in much less time than required on horseback in demonstrated areas. Using drones reduces the workload of the rider and horse, saving time and energy and reducing the risk of injury. With proper training and certification, livestock producers can use drones to locate cattle and perform many other cost-cutting operations.

Nutritional Evaluation Of Hydroponic Corn Fodder And Its Effect As Substitute For Feed Concentrates For Buffalo Calves, Charity I. Castillo, Phoebe Lyndia T. Llantada, Cyril P. Baltazar, Mary Rose D. Uy-De Guia, Reynald D. Amido, Arnel N. Del Barrio

The Philippine Agricultural Scientist

This study investigated the effects of hydroponic corn fodder on the growth performance of buffalo calves. Twelve Bulgarian Murrah buffalo calves were divided into two treatment groups: T1, fed with Napier grass and starter feed concentrates, and T2, fed with Napier grass, starter feed concentrates, and hydroponic corn fodder, replacing 50% of the starter feed concentrate. The study found no significant differences between the two groups' average total weight gain and average daily gain. However, the average daily feed intake was significantly higher in T2, possibly due to the tender and young nature of the hydroponic corn fodder. Dry matter …

Effects Of Mature Recombinant Gdf9 And Bmp15 On In-Vitro Maturation Of Bovine Oocytes And Subsequent Embryo Development And Effects Of Antioxidants On Blastocyst Re-Expansion Rates, Jamie Thompson

Master's Theses

In-vitro produced embryos (IVP) differ greatly from in-vivo derived embryos (IVD) in gene expression, metabolism, development, and cryotolerance which limit the widespread use of this technology. In-vitro maturation (IVM) is one of the most important components for successful in-vitro embryo development. Growth differentiation factor 9 (GDF9) and bone morphogenetic protein 15 (BMP15) have been found to be essential during oocyte maturation and thus female fertility. These proteins are oocyte secreted factors (OSFs) and are produced with pro- and mature protein regions where the pro-regions are thought to aid in protein folding and dimerization where heterodimerization the two proteins has been …

Animal Husbandry In The 21st Century: Application Of Ecological Theory And Precision Technology To Inform Understanding Of Modern Grazing Systems, Ira Lloyd Parsons

Theses and Dissertations

Ruminant animals comprise the greatest proportion of herbivores around the world, provide essential ecosystem services and human consumable protein by consuming grass and human inedible dietary fiber. Herbivory pressure alters plant communities and species diversity, effectively making grazing animals ecosystem engineers in dynamic ecosystems. Development of advanced computer processing power coupled with biometric and ecosystem sensors may be employed in the internet of things framework to create an integrated information system designed to inform understanding of grazing system function and animal energy balance. Towards this end, I utilized Bos indicus / Bos taurus crossbred steers (n = 20) across two …

Escherichia Coli And Salmonella Sp. In Domestic Cattle And Wild Roosevelt Elk: Fecal Pathogens At The Wildlife-Domestic Interface, Emily A. Buck

Cal Poly Humboldt theses and projects

Direct or indirect contact between domestic populations of animals and wildlife carries an inherent risk for transmission of pathogens that cause infectious disease. In Humboldt and Del Norte counties of northern California, ongoing conflict between ranchers and Roosevelt elk groups results from elk use of ranching pastures and pastures on private land. Fecal samples from elk in association with cattle, cattle, and from elk not in known association with cattle were assessed for the presence of bacteria Salmonella enterica and pathogenic Escherichia coli to assess whether association with cattle increases risk of infection for elk. Group identity (one of the …

Hotline Number To Reach And Offer Agricultural Information To Plain Anabaptists During The Covid-19 Workplace Closures, Emily Shoop, Carly Becker, Nathan Glenn Briggs, Danielle Smarsh

Journal of Amish and Plain Anabaptist Studies

The Penn State Extension Animal Systems Team developed a toll-free hotline phone number to convey short educational messages to maintain contact and outreach to Pennsylvania’s animal producing Amish, Mennonite, and other plain Anabaptist populations. During the COVID-19 pandemic, Penn State Extension’s programming went largely online via webinars, online courses, and emails. This change in programming excluded a large sector of Pennsylvania farmers who do not use or have access to the internet and, as such, were liable to miss important best management practice reviews and timely updates in animal agriculture. The Animal Systems Hotline offered callers the choice to listen …

Relationship Of Winter Hair Coat Shedding Ability Of Purebred Angus Dams With Mineral Status, Apparent Forage Digestibility, Uterine Artery Hemodynamics, And Calf Growth And Development, Randy Hunter Burnett

Theses and Dissertations

Winter hair coat shedding ability in southern U.S. cattle production has previously been associated with differences in adjusted birth and weaning weights of calves from dams that shed by June or later (Gray et al., 2011; Cauble et al., 2019). This study was developed to research possible avenues of why these relationships exist with winter hair coat shedding ability. The primary objectives of the following experiments were to: 1) evaluate how mineral status relates to winter hair coat shedding ability, 2) evaluate how winter hair coat shedding ability relates to apparent digestibility of forage, 3) evaluate winter hair coat shedding …

Forage clippings were analyzed for dry matter, crude protein, and neutral detergent fiber. Body weights were monitored over the grazing period. Blood samples were collected during the experiment, and animals were slaughtered for the evaluation of carcass traits. Data were analyzed …

Bovine Liver Supplement Labeling Practices And Compliance With U.S. Regulations, Anthony J. Silva, Olive J. Dahm, Rosalee S. Hellberg

Food Science Faculty Articles and Research

Bovine liver supplements are sought after by consumers due to their nutrient-dense profile and high protein content. However, there is a lack of information regarding bovine liver supplement labeling practices. The objective of this study was to assess labeling practices and compliance with U.S. regulatory standards among commercially sold bovine liver supplements. The product labels for 49 bovine liver supplements were examined for required information, including a statement of identity; net quantity of contents; “Supplement Facts” label; ingredient statement; and name and place of business of manufacturer, packer, or distributor with domestic address or telephone number. Any claims made on …

Effects Of Supplemental Whole Cottonseed On Weaned Calf Production, Zachary Debord

Mahurin Honors College Capstone Experience/Thesis Projects

This study compared the effect of supplemental whole cottonseed in a weaned calf ration on cattle productivity. Feed is the main cost for livestock production. Whole cottonseed supplementation may increase production and reduce the cost of gain for the ration. During the study, 18 beef calves were weaned and split into two groups and fed, with and without WCS, for 50 days to determine the effect of supplemental whole cottonseed. Productivity was determined by measuring average daily gains for each group and comparing cost of gain for each ration. It was determined that WCS did increase productivity of weaned calves …

Characterizing Cytoplasmic Maturation And Improving Competence Of Bovine In Vitro Matured Oocytes, Brittany Alanna Foster

LSU Doctoral Dissertations

As the necessity to improve in vitro embryo production efficiency is ever increasing, so too is the prerequisite obligation to improve oocyte competence. The ability of an oocyte to successfully produce a viable embryo requires that it both completes meiotic maturation and synchronously achieves cytoplasmic competence; an encompassing term that refers to the oocytes correct accumulation and storage of mRNAs, proteins and factors as well as the development and reorganization of organelles and the cytoskeleton. The current research was designed to analyze those methods that go into oocyte collection and pre-maturation handling to determine if there are ways to ensure …

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 …

Polymorphisms Of Bovine Hsp90 And Their Implications In Beef Cattle Productivity, Glynn G. Smith

Animal Science Undergraduate Honors Theses

Production of beef cattle represents a $60 billion industry in the United States (USDA, 2015). The American beef cattle industry loses an estimated $370 million annually due to heat stress (St-Pierre, 2003). As of 2003, this was equal to nearly 99 million pounds of beef lost (USDA, 2015). The average American consumed roughly 65 pounds of beef in 2003; this means that the 99 million pounds of beef lost to heat stress would have been enough to feed approximately 1.5 million Americans for an entire year (Barclay, 2012).

The Three Creeks Allotment Consolidation: Changing Western Federal Grazing Paradigms, Taylor Payne

Human–Wildlife Interactions

The federal government owns approximately 47% of all land in the western United States. In the state of Utah, about 64% of the land base is managed by the federal Bureau of Land Management (BLM) and the U.S. Forest Service (USFS). The government has historically issued permits to owners of private lands to allow the owners to graze their livestock on public lands. The permits (allotments) are generally of 10-year duration and allow for an annual season of use. In some cases, continued and repeated historical annual grazing practices may not be ideal for permit holders and their communities nor …
