A Mechanistic Examination Of Interspecific Competition Between Wild And Domestic Herbivores, Courtney Check
A Mechanistic Examination Of Interspecific Competition Between Wild And Domestic Herbivores, Courtney Check
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Large herbivores, such as mule deer and cattle have similar life histories and likely compete for resources. However, quantifying the extent to which these species compete and the specific resources they compete for has proved challenging. My research examines if cattle influence deer abundance and behavior due to competition for forage, competition for shade, and/or by affecting the predation risk of deer. Using a grid of autonomous trail cameras, I was able to determine if cattle abundance influences local deer abundance in relation to specific resources and habitat features. Using GPS data from collared deer, I was also able to …
Effects Of Supplemental Trace Minerals As Amino Acid Complexed Or Inorganic Sources For Beef Cattle From Receiving Through Finishing, Robin Ashley Cheek
Effects Of Supplemental Trace Minerals As Amino Acid Complexed Or Inorganic Sources For Beef Cattle From Receiving Through Finishing, Robin Ashley Cheek
Graduate Theses and Dissertations
The objective of experiments was to investigate the effects of inorganic or amino acid-complexed sources of trace minerals on health, gain performance, liver mineral concentrations, and carcass characteristics of beef heifers from receiving through finishing. To investigate the effects of inorganic or amino acid-complexed sources of trace minerals (zinc, copper, manganese, and cobalt) on performance and morbidity of beef heifers during the receiving period, crossbred beef heifer calves arriving on 3 delivery dates were used in a 42-day receiving trial. Treatments consisted of supplemental zinc (360 mg/d), copper (125 mg/d), manganese (200 mg/d), and cobalt (12 mg/d) from complexed (Availa-4, …
Identifying Barriers To Data Use On U.S. Beef Cow-Calf Operations And Developing Solutions To Improve Cow-Calf Record-Keeping, William Isaac Jumper
Identifying Barriers To Data Use On U.S. Beef Cow-Calf Operations And Developing Solutions To Improve Cow-Calf Record-Keeping, William Isaac Jumper
Theses and Dissertations
Cattle health and production records (CHPR) are data collected by cattle producers and veterinarians in the form of measurements, observations, counts of events over time, and physiologic attributes that describe individual and group-level health and production. These data are useful to both veterinarians and cattle producers for making evidence-based decisions on cow-calf operations. Currently, there are no uniform, industry-wide methods of capturing and recording CHPR in the U.S. cow-calf industry. Although many cow-calf producers in the U.S. are thought to collect some form of CHPR, it is believed that relatively few are doing so in an electronic manner that facilitates …
Pharmacokinetics Of Single Feeding Of Cannabidiol In Cattle: A Pilot Study, Haley Cornette
Pharmacokinetics Of Single Feeding Of Cannabidiol In Cattle: A Pilot Study, Haley Cornette
Honors College Theses
Cannabidiol (CBD) is a substance that has been used in complementary medicine for many years. However, modern medicine has little knowledge of how this substance is utilized and metabolized in ruminant animals. Regulations on quality assurance and use in animals are lacking, and CBD supplementation in livestock is not approved. If CBD supplements can be shown to be safe and effective, detection in the animal will be important for determining regulation of use. A withdrawal period can then be established to allow time for deterioration of product to safe levels before livestock products enter human markets. This study sought to …
Effects Of Biosynthesized Bromoform On Enteric Methane Production, Animal Performance And Tissue Residues In Cattle, Sydney Davis
Effects Of Biosynthesized Bromoform On Enteric Methane Production, Animal Performance And Tissue Residues In Cattle, Sydney Davis
Theses and Dissertations--Animal and Food Sciences
Greenhouse gas (GHG) emissions have been implicated in global warming and extreme climate change conditions. The Environmental Protection Agency (EPA) has identified agriculture, more specifically cattle production, as a major contributor to global GHG production. When expressed as liters of gas, CO2 is considered the primary GHG produced, however, in terms of global warming potential (GWP), CH4 has 25-times greater potential than that of CO2. Due to the elevated GWP of CH4, we have constructed a series of experiments to investigate the use of a halogenated CH4 analogue derived from kelp (i.e., bromoform) as an inhibitor of enteric CH4 production …
Potentials Of Pleurotus: Reimagining The Relationship Between Cattle And Brewer's Spent Grain, Zoe Stojkovic
Potentials Of Pleurotus: Reimagining The Relationship Between Cattle And Brewer's Spent Grain, Zoe Stojkovic
Senior Projects Spring 2023
Brewer’s spent grains (BSGs), a byproduct from beer production, are generated in excess globally. Most often, they are sold or given to proximate cattle farmers for use as feed. However, spent grain can also be used as a medium for fungal cultivation. Given that certain fungal species have the capability to degrade lignin and produce protein, the cultivation of fungi on spent grains may serve to enhance the nutritional profile of the grains for their use as cattle feed. This project is an effort to determine the compatibility of fungal cultivation with BSGs in order to both improve upon cattle …
