Temporal And Spatial Influences On Fawn Summer Survival In Pronghorn Populations: Management Implications From Noninvasive Monitoring, Cole A. Bleke, Eric M. Gese, Juan J. Villalba, Shane B. Roberts, Susannah S. French

Wildland Resources Student Research

Monitoring vital rates allows managers to estimate trends in growth rates of ungulate populations. However, connecting the influence of nutrition on ungulate demography is challenging. Noninvasive sampling offers a low-cost, low-effort alternative for measuring nutritional indices, allowing for an increased understanding of the mechanistic relationships between environmental factors, nutrition, and specific population vital rates. We examined the temporal influence of intrinsic and extrinsic factors on pronghorn (Antilocapra americana) fawn recruitment. We collected fresh fecal samples from adult female pronghorn in five subpopulations spanning three sampling periods associated with critical maternal life-history stages (late gestation, early lactation, breeding season) …

Chronic inflammation increases the risk of developing multiple chronic diseases, including cancer. The risk of developing colorectal cancer (CRC) specifically is increased in individuals who suffer from colitis, a characteristic of Inflammatory Bowel Disease (IBD). Diet is another risk factor for developing CRC, particularly an inflammation-promoting Western-type diet. Thus, supplementing a Western diet with functional foods containing anti-inflammatory polyphenols is a potential approach to decreasing CRC risk by reducing gut inflammation and altering gut microbiome profile. This study aimed to determine the effects of cocoa polyphenol (CP) supplementation on inflammation status and microbiome profile before, during, and after colitis when …


Grazing On The Arizona Strip: Catchment History And Repair, Melanie Heaton Apr 2024

Grazing On The Arizona Strip: Catchment History And Repair, Melanie Heaton

All Current Publications

Water, not forage, is the limiting factor for wildlife and livestock grazing the Arizona Strip, a nearly 3-million-acre piece of land located north of the Grand Canyon and south of the Utah border. Since springs and groundwater are rare or absent, harvesting of natural precipitation is the main source of water for animals. Catchment systems, which capture precipitation on a sloped rubber apron and contain it in a large tank or lined pond, are used by government agencies and grazing permittees to efficiently provide water for wildlife and livestock. As catchments reach the end of their useful lives, tank replacement …

You Can Lead A Horse To Water: Mapping Seasonal Water Resources To Predict Wild Horse Movements On Utah Rangelands, David C. Stoner, Eric Thacker, Linden Greenhalgh, Mark Nelson

All Current Publications

All wild horse herd management areas in Utah overlap BLM grazing allotments. Although horses and cattle have similar dietary habits, both species rely heavily on predictable water sources during dry periods. The concentration of wildlife and livestock in mesic areas during droughts can become problems for farmers and livestock producers. We aimed to map the annual distribution of temporary surface water across Utah that cattle, horses, and wildlife could use. Herein we analyzed an 18-year record of satellite imagery to create a statewide map of seasonal surface-water availability for agricultural and wildlife management purposes.


Non-Random Sampling Measures The Occurrence But Not The Strength Of A Textbook Trophic Cascade, Daniel R. Macnulty, Elaine M. Brice, Eric J. Larsen Nov 2023

Non-Random Sampling Measures The Occurrence But Not The Strength Of A Textbook Trophic Cascade, Daniel R. Macnulty, Elaine M. Brice, Eric J. Larsen

Wildland Resources Faculty Publications

Although sampling the five tallest young aspen in a stand is useful for detecting the occurrence of any aspen recruitment, this technique overestimates the population response of aspen to wolf reintroduction. Our original conclusion that random sampling described a trophic cascade that was weaker than the one described by non-random sampling is unchanged.

Equine Navicular Syndrome, Kylie Stephens, Karl Hoopes Jun 2023

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 …

Raising A Bottle-Fed Calf On A Cow/Calf Operation, Reganne K. Briggs, Katelyn Barsnick, Cheyenne Reid, Ashley Longmore

All Current Publications

Having bottle-fed calves on the ranch is common for beef producers. The most likely scenarios are a cow has died, a cow isn’t giving enough milk, or a twin has been rejected. All these scenarios are likely to happen, which results in an orphan calf. Bottle-feeding a calf is straightforward; however, there are limited resources, specifically for beef producers, looking for bottle-fed calf management strategies. When bottle-feeding a beef calf, there are some things to consider, such as feeding colostrum, selecting and using milk replacers, and weaning the calf. Many of the resources on bottle-calf management come from the dairy …

Mice As An Animal Model For Japanese Encephalitis Virus Research: Mouse Susceptibility, Infection Route, And Viral Pathogenesis, Jordan C. Frank, Byung-Hak Song, Young-Min Lee

Animal, Dairy, and Veterinary Science Faculty Publications

Japanese encephalitis virus (JEV), a zoonotic flavivirus, is principally transmitted by hematophagous mosquitoes, continually between susceptible animals and incidentally from those animals to humans. For almost a century since its discovery, JEV was geographically confined to the Asia-Pacific region with recurrent sizable outbreaks involving wildlife, livestock, and people. However, over the past decade, it has been detected for the first time in Europe (Italy) and Africa (Angola) but has yet to cause any recognizable outbreaks in humans. JEV infection leads to a broad spectrum of clinical outcomes, ranging from asymptomatic conditions to self-limiting febrile illnesses to life-threatening neurological complications, particularly …

Effects Of Pregnancy And Progesterone On Atrial Fibrillation, Heloisa M. Rutigliano Apr 2023

Effects Of Pregnancy And Progesterone On Atrial Fibrillation, Heloisa M. Rutigliano

Browse all Datasets

Atrial Fibrillation (AF) is the most common cardiac arrythmia in adults with likely sex-specific risk factors. Female sex hormones may be important in modulating risk for atrial fibrillation. We hypothesize that pregnancy and progesterone (P4), a hormone found in high levels during pregnancy with abrupt withdrawal immediately after parturition, modulates AF susceptibility in female goats. Cardiac specific TGF-?1 transgenic female goats and age-matched wild-type (WT) female goats were utilized. Pacemakers were implanted in all animals for continuous arrhythmia monitoring and AF inducibility. AF inducibility was evaluated using 5 separate 10 s bursts of atrial pacing (160 - 200 ms). In …

Consumption of the total Western diet (TWD) in mice has been shown to increase gut inflammation, promote colon tumorigenesis, and alter fecal microbiome composition when compared to mice fed a healthy diet, i.e., AIN93G (AIN). However, it is unclear whether the gut microbiome contributes directly to colitis-associated CRC in this model. The objective of this study was to determine whether dynamic fecal microbiota transfer (FMT) from donor mice fed either the AIN basal diet or the TWD would alter colitis symptoms or colitis-associated CRC in recipient mice, which were fed either the AIN diet or the TWD, using a 2 …

Black raspberries (BRB) are rich in anthocyanins with purported anti-inflammatory properties. However, it is not known whether dietary supplementation would ameliorate Western-diet enhanced gut inflammation and colon tumorigenesis. We employed a mouse model of colitis-associated colorectal cancer (CAC) to determine the effects of dietary supplementation with 5 to 10% (w/w) whole, freeze-dried BRB in male C57BL/6J mice fed either a standard healthy diet (AIN93G) or the total Western diet (TWD). In a pilot study, BRB suppressed colitis and colon tumorigenesis while also shifting the composition of the fecal microbiome in favor of taxa with purported health benefits, including Bifidobacteria pseudolongum. …

Importance Of A Dietary Cation-Anion Difference In Peripartum Dairy Cows, Laura A. Motsinger, Jacob Hadfield Apr 2022

Importance Of A Dietary Cation-Anion Difference In Peripartum Dairy Cows, Laura A. Motsinger, Jacob Hadfield

All Current Publications

At calving, nutrient requirements of dairy cows increase to support milk synthesis. Energy and protein requirements are increased at the initiation of lactation (Moore et al., 2000). Additionally, calcium requirements increase tremendously to meet the demands of lactation (Moore et al., 2000). Calving and subsequent milk synthesis can cause calcium concentrations in the blood to drop. When the demand for calcium exceeds the cow’s ability to mobilize calcium, hypocalcemia (low blood calcium) occurs, which can negatively impact production. This fact sheet reviews hypocalcemia in dairy cows and how to implement hypocalcemia prevention strategies.
