Seasonality Of Bovine Respiratory Disease Incidence, Nasal Temperatures, And The Nasal Microbiome In Receiving Beef Cattle: Understanding The Risk Of The Bovine Respiratory Disease Complex, Robin Ashley Cheek

Graduate Theses and Dissertations

Bovine respiratory disease (BRD) has persistently been the leading cause of morbidity of beef cattle in the United States. Season has been directly associated with respiratory disease incidence and is likely a proxy for weather conditions, which vary by geographical location. The nose is one of the first points of contact between the outside environment and inside the body. The nasal microbiome and its relationship with BRD have been heavily studied within beef cattle, but there are not yet any studies to determine if the environment within the nasal cavity has a role to play in this mechanism. This dissertation …

Challenges And Opportunities In Dry Aging: Producer Perspectives And Valorization Of Dry- Aged Waste Products, Peyton Scout Arnold

Graduate Theses and Dissertations

Despite the projected increase in the dry aging market, producers may be hesitant to incorporate dry aging practices. This thesis aims to identify primary concerns faced by producers in implementing a dry aging program. Semi-structured interview surveys were conducted via Qualtrics (N = 100). Results indicated that an “advanced” level of dry aging knowledge correlated with a higher importance in the use/sale of dry aged products (P = 0.02). Cost, demand, and sourcing were the top three concerns of producers practicing dry aging. Those considering implementation were concerned with cost, processing parameters, safety, demand, and sourcing. No significant differences were …

Metabolic Markers And Gut Microbiota In Big Cats: A Relationship Between Diet, Health And Environment, Javeria Saman, Saima Sharif, Bushra Nisar, Shagufta Naz

Journal of Bioresource Management

The wild animals that occupy large territories were found to adapt less easily to captive environments compared to those with small home ranges. Among big cats, captivity posed a range of challenges, with stress emerging as central factor influencing overall welfare. Transition into captive environment was shown to alter both behavior and physiological processes, largely due to changes in their natural habitat, environmental complexity and diet. Several health issues reported in big cats including alopecia, gastrointestinal issues, neuromuscular disorders such as hindquarter paralysis were associated with underlying metabolic dysregulation. Metabolic health was recognized as critical component of overall well-being, closely …

Vitamin C (Ascorbic Acid) Supplementation In Caprine Semen Extenders: Current Evidence, Knowledge Gaps, And Implications For Triladyl® Based Preservation Systems, Abdul Saboor Brohi, Qudratullah Kalwar, Muhammad Mohsen Rahimoon, Hidayatullah Soomro, Hubdar Ali Kolachi, Rafique Ahmed Shar, Muhammad Awais Soomro, Abdul Aleem Korejo, Muhammad Arslan Yousaf Rehan, Sajad Ali Laghari

Journal of Bioresource Management

Cryopreservation of goat semen is an essential tool for genetic improvement, germplasm conservation, and the expansion of artificial insemination programs in caprine breeding. However, buck spermatozoa are highly susceptible to cryo-induced oxidative stress due to their membrane composition rich in polyunsaturated fatty acids. Excessive generation of reactive oxygen species during semen processing, freezing, and thawing compromises sperm motility, viability, membrane integrity, mitochondrial function, and DNA stability, ultimately reducing post-thaw fertilizing potential. Semen extenders play a pivotal role in mitigating these detrimental effects by providing cryoprotection and maintaining cellular homeostasis. Among commercial extenders, Triladyl® is widely used in ruminant semen preservation; …

Validity of Uroplectes ngangelarum Monard, 1930 is confirmed as different from U. planimanus (Karsch, 1879); its lectotype is designated. Lectotype is also designated for Uroplectes planimanus …

Dimensional Welfare Beyond Pain: Extending The Precautionary Principle In Birch’S “The Edge Of Sentience”, Willa M. Lane, Nicola S. Clayton

Animal Sentience

Birch's (2024) The Edge of Sentience identifies sentience candidates primarily through the pain-focused LSE Criteria. Yet, as Birch himself notes in Proposal 17, sentience is not pain. We argue that statutory welfare protections must therefore reach beyond pain, and that the right tool for doing so is Birch et al.’s (2020) dimensionality framework, which characterises conscious experience across five domains. Used together, the LSE Criteria establish that welfare is at stake, while the dimensionality framework maps what is at stake beyond pain to provide a taxon-specific profile of where captivity impoverishes experience. We apply this approach to invertebrate welfare and …

History And Distribution Of Great-Tailed Grackles (Quiscalus Mexicanus) In Arkansas, R. Tumlison, V. Andersen

Journal of the Arkansas Academy of Science

Great-tailed Grackles (Quiscalus mexicanus) were reported first in southwestern Arkansas in 1969, were nesting there in 1977, and established a resident population by 1980. Nesting was reported in far northwestern Arkansas in 1986. Presently, the species is known from 44 of Arkansas’s 75 counties, those mostly in the western and central counties. Most individuals appear to be migratory, with most reports occurring in April and May. However, breeding and now resident populations have been reported in the southwestern, northwestern, and central counties, particularly in urban areas. Birds are very commonly reported to forage at fast-food establishments and truck …

Testing The Accuracy Of A Bear-Tracking Satellite Transmitter Collar Under Natural Conditions, K. A. Watson, K. Phipps, C. Drexler, C. R. Middaugh, M. Means, M. Hooks

Journal of the Arkansas Academy of Science

The Arkansas Game and Fish Commission tracks American black bears (Ursus americanus) using Global Positioning System (GPS) satellite telemetry collars in southeastern Arkansas to assess habitat use and behaviors. Companies test the accuracy of their devices, but researchers have found that natural environments, such as the forested habitat of black bears, can cause an increase in spatial error rates. We therefore tested 1 GPS collar in realistic conditions to help refine data interpretation. We placed the collar at 20 random locations in Columbia County, AR, stratifying habitat type based on data collected from black bears. We determined the …

Endeavors: Mississippi State Undergraduate Research Journal

Bovine respiratory disease (BRD) is a multifactorial disease complex that causes significant economic loss in the cattle industry. Bovine respiratory syncytial virus (BRSV), one of the primary viruses included in BRD, primarily targets the lower respiratory tract and causes a wide variety of subclinical and clinical signs. Current diagnosis techniques require off-site laboratory testing, creating delays that allow BRSV to spread through herds and highlighting the need for rapid diagnostic methods. The objective of the study was to evaluate near-infrared spectroscopy as a diagnostic tool for BRSV detection across varying infection severities. Twenty-two Holstein bull calves were reared in research …
