Forages And Technology Management In Growing And Finishing Beef Cattle Systems, Kelton Adair

Theses and Dissertations in Animal Science

A systems study evaluated the effects of an implant [25.7 mg estradiol (Compudose; Elanco Animal Health)] at two rates of gain (LOW: 0.45 kg/d and HIGH: 0.9 kg/d) applied during the winter backgrounding phase in drylot and winter grazing systems and its effects on subsequent phases of production. HIGH supplementation with an implant during the winter backgrounding phase in the drylot system yielded the greatest ending body weight (EBW) during the summer backgrounding phase (P = 0.04). LOW supplementation, without an implant, improved summer backgrounding average daily gain (ADG; P = 0.05) while achieving similar carcass adjusted final body …

Multispecies Genomic Sex Identification Using Ddx3 Gene Polymorphisms, Jessica Felts

All Graduate Theses and Dissertations

PCR sex determination assays must be reliable and cost effective due to the frequent and integral use of these assays in biological research and the animal production industry. Thus, the design of proof of a primer pair with a built-in control is warranted to not only bypass the extra cost of a multiplex reaction, but also to prevent anomalous results that have been documented with other primer pairs.

The objective of this study was to design primer pairs with built in PCR amplification control to identify sex in Equus caballus (domestic horse), Homo sapiens (humans), Macaca mulatta (rhesus macaque), and …

Consumption Of A Western Diet Enhanced Colitis-Associated Colorectal Cancer And Dysbiosis Of The Fecal Microbiome In Mice Notwithstanding Dietary Intervention Or Fecal Microbiome Transfer, Daphne Michelle Rodriguez Jimenez

All Graduate Theses and Dissertations

In a rodent model of inflammation-associated colorectal cancer, consumption of a Western-style diet increases gut inflammation and enhances risk of developing colon tumors. The goal of this dissertation was to understand the contribution of bacteria within the large intestine on colon inflammation and colon tumorigenesis. Two pre-clinical animal studies were performed using two different intervention strategies to shift the microbiome, and potentially gut inflammation and tumor development: 1) an experiment using dietary supplementation with black raspberries, a functional food enriched in bioactive anthocyanins with purported antiinflammatory activity, and 2) an experiment using fecal microbiota transfer from mice fed a healthy …

Anthropogenic Factors Affecting Common Raven Occurrence And Depredation Of Artificial Nests Within Greater Sage‐Grouse Habitat In Southern Utah, Zoë S. Moffett

All Graduate Theses and Dissertations

Certain species of wildlife are more generalist and adaptive than others. These species often flourish when supported by human activities that provide additional food and habitat for them. The common raven (Corvus corax; hereafter raven) is one such species; their populations have risen and spread throughout the Intermountain West. As generalist scavengers and predators, ravens have been found to pose a severe threat to several threatened or sensitive species, including the greater sage-grouse (Centrocercus urophasianus; hereafter sage-grouse). The purpose of my research was to determine the specific anthropogenic and habitat factors that may increase the threat …

Molecular And Morphological Confirmation Of Isometrus Maculatus (Degeer, 1778) (Scorpiones: Buthidae) From Northeast India And East Asia, Shubhankar Deshpande, Mihir Joshi, Kazusa Kawai, Arnab Deb, Jeng-Di Lee, Deshabhushan Bastawade, Gaurang Gowande, Shauri Sulakhe

Euscorpius

We present molecular data on Isometrus maculatus (DeGeer, 1778) for the first time from India, Japan, and Taiwan based on the COI gene and justify the cosmopolitan nature of this species. We also address the first population of I. maculatus found in Teliamura, Tripura, India and give its detailed description and comparison with the rest of the Isometrus species from India. Furthermore, we discuss the justification for considering Sri Lanka as the true home of I. maculatus.

Alternatives To Antibiotics In Veterinary Medicine: Considerations For The Management Of Johne's Disease, Laura M. O'Connell, Aidan Coffey, Jim O'Mahony

Dept. of Biological Sciences Preprints

Antibiotic resistance has become a major health concern globally, with current predictions expecting deaths related to resistant infections to surpass those of cancer by 2050. Major efforts are being undertaken to develop derivative and novel alternatives to current antibiotic therapies in human medicine. What appears to be lacking however, are similar efforts into researching the application of those alternatives, such as (bacterio)phage therapy, in veterinary contexts. Agriculture is still undoubtedly the most prominent consumer of antibiotics, with up to 70 % of annual antibiotic usage attributed to this sector, despite policies to reduce their use in food animals. This not …

Limits To Sentience, Donald M. Broom

Animal Sentience

There are many parallels between cellular function in animals and plants. Plants can have complex interactions with their environments. But they lack a central nervous system, which is a prerequisite for sentience (the capacity to feel). In my view the suggestion that plants are sentient is not only empirically incorrect but potentially harmful to the efforts to protect the welfare of sentient beings.

Equine Navicular Syndrome, Kylie Stephens, Karl Hoopes

All Current Publications

Equine navicular syndrome has a large effect on the horse industry by accounting for up to one third of all chronic forelimb lamenesses. While the exact cause and development of this disease is still widely controversial, there are noticeable and significant changes to the internal anatomy and structures that could contribute to the possible onset of lameness. Three main causes are proposed that could play a role in the progression of this syndrome: biomechanical forces, vascular alterations, and chronic inflammation. The clinical signs of navicular syndrome can range from short choppy strides to intermittent lameness, as well as gait changes …

Spatial And Temporal Activity Patterns Among Sympatric Tree-Roosting Bat Species In An Agriculturally Dominated Great Plains Landscape, Christopher Fill, Craig R. Allen, John F. Benson, Dirac Twidwell

Nebraska Cooperative Fish & Wildlife Research Unit -- Staff Publications

In agroecosystems, bats can provide a critical ecosystem service by consuming night-flying insect pests. However, many bats also face intense population pressures from human landscape modification, global change and novel diseases. To better understand the behavioral activity of different bat species with respect to space, time, habitat, and other bat species in this environment, we investigated species correlations in space and time over row crop agricultural fields. We used acoustic grids to document spatial and temporal co-occurrence or avoidance between bats and recorded eight species across the 10 field sites we sampled. All species significantly overlapped in two-dimensional space and …
