Heat stress (HS) is devastating to the poultry industry due to its adverse effects on animal well-being and performance. The effects of heat stress are typically measured using a portable i-STAT blood analyzer that quantifies circulatory hemoglobin concentration and other blood chemistry parameters. Here, we used diffuse reflectance spectroscopy (DRS) as a novel non-invasive method to directly determine changes in hematological parameters in the breast tissues of live heat-stressed broilers. Three-week-old male broilers were randomly subjected to two environmental conditions (thermoneutral, TN, 24 °C vs. cyclic heat stress, HS, 35 °C, 12 h/day). Optical spectra were acquired using DRS to …

Background

Interest in the use of natural feed additives as an alternative to antimicrobials in the poultry industry has increased in recent years because of the risk of bacterial resistance. One of the most studied groups are polyphenolic compounds, given their advantages over other types of additives and their easy potentiation of effects when complexes are formed with metal ions. Therefore, the objective of the present study was to evaluate the impact of dietary supplementation of copper acetate (CA), curcumin (CR), and their combination (CA-CR) against Salmonella Typhimurium colonization, intestinal permeability, and cecal microbiota composition in broiler chickens through a …

Forward osmosis (FO) is an important desalination method to produce potable water. It was also used to treat different wastewater streams, including industrial as well as municipal wastewater. Though FO is environmentally benign, energy intensive, and highly efficient; it still suffers from four types of fouling namely: organic fouling, inorganic scaling, biofouling and colloidal fouling or a combination of these types of fouling. Membrane fouling may require simple shear force and physical cleaning for sufficient recovery of membrane performance. Severe fouling may need chemical cleaning, especially when a slimy biofilm or severe microbial colony is formed. Modification of FO membrane …


Evidence Of Mitochondrial Dysfunction In Bacterial Chondronecrosis With Osteomyelitis–Affected Broilers, Alison Ferver, Elizabeth S. Greene, Robert F. Wideman Jr., Sami Dridi Feb 2021

Evidence Of Mitochondrial Dysfunction In Bacterial Chondronecrosis With Osteomyelitis–Affected Broilers, Alison Ferver, Elizabeth S. Greene, Robert F. Wideman Jr., Sami Dridi

Poultry Science Faculty Publications and Presentations

A leading cause of lameness in modern broilers is bacterial chondronecrosis with osteomyelitis (BCO). While it is known that the components of BCO are bacterial infection, necrosis, and inflammation, the mechanism behind BCO etiology is not yet fully understood. In numerous species, including chicken, mitochondrial dysfunction has been shown to have a role in the pathogenicity of numerous diseases. The mitochondria is a known target for intracellular bacterial infections, similar to that of common causative agents in BCO, as well as a known regulator of cellular metabolism, stress response, and certain types of cell death. This study aimed to determine …

Dysregulation Of The Muscle Clock During Development Of Cancer Cachexia, Madeline Amos Jan 2021

Dysregulation Of The Muscle Clock During Development Of Cancer Cachexia, Madeline Amos

2021 Honors Symposium

INTRODUCTION
Cancer continues to be one of the leading causes of death across the world. Among many conditions that accompany cancer, cachexia is one that has long been identified as an unfortunate consequence. Cachexia is a skeletal muscle-wasting syndrome that ultimately leads to deterioration in the body’s functional ability and is considered to be irreversible solely by nutritional means. Researchers have yet to identify the precise mechanisms responsible for its development and current treatments remain inadequate.

PURPOSE
The purpose of this study was to confirm the dysregulation of Clock gene expression in male and female tumor-bearing mice, whether such effects …

Investigation Of Fluorescence In Selected Mammals Of Arkansas, C. Renn Tumlison, Terry L. Tumlison Jan 2021

Investigation Of Fluorescence In Selected Mammals Of Arkansas, C. Renn Tumlison, Terry L. Tumlison

Journal of the Arkansas Academy of Science

The adaptive value of fluorescence among the vertebrates has been studied most in fishes and birds, and only a few observations have been published regarding fluorescence in the pelage of mammals. Recently, reports of fluorescence in some marsupials, the platypus, and in flying squirrels have become available. We report the occurrence of fluorescent properties in some mammals from Arkansas. Most carnivores, bats, and rodents did not exhibit the property when viewed under UV light. However, opossums, rabbits, a weasel, muskrats, and moles showed substantial UV response, and a few other mammals showed minor fluorescence. Colors fluoresced included pink, green, and …


Morphology Of Rathke’S Glands In The Alligator Snapping Turtle, Macrochelys Temminckii (Chelonia: Chelydridae), Stanley E. Trauth Jan 2021

Morphology Of Rathke’S Glands In The Alligator Snapping Turtle, Macrochelys Temminckii (Chelonia: Chelydridae), Stanley E. Trauth

Journal of the Arkansas Academy of Science

I examined the morphology of Rathke’s glands (RG) in the Alligator Snapping Turtle, Macrochelys temminckii, using light microscopy and scanning electron microscopy. This species possesses 4 pairs of RG (i.e., an axillary and three inframarginals) that are embedded beneath marginal bones and are named primarily according to the anatomical location of their orifices. These holocrine-type, exocrine, integumentary glands are anatomically and ultrastructurally similar to one another. Each gland contains a single and highly vascularized secretory lobule, which is bounded by a thick tunic of asymmetrically-arranged striated muscle bundles. Two types of secretory vacuoles were identified within the holocrine cells …

Journal of the Arkansas Academy of Science

Palmer’s pigweed (Amaranthus palmeri) is a common grassland plant that occurs across much of North America. It is often considered a weed but is an important source of food for many game birds. We analyzed the energy content of seeds of Palmer’s pigweed obtained from the crops of scaled quail (Callipepla squamata) collected from plains-mesa sand-scrub habitat in Eddy and Lea counties, New Mexico. Seeds were dried for 48 hours at 60°C to remove moisture and then analyzed for gross caloric value (i.e., energy content) in an oxygen bomb calorimeter. Energy content of seeds of Palmer’s …


Distribution And History Of The Roseate Spoonbill (Platalea Ajaja) In Arkansas, C. Renn Tumlison, Grace Wills, Karen Rowe Jan 2021

Distribution And History Of The Roseate Spoonbill (Platalea Ajaja) In Arkansas, C. Renn Tumlison, Grace Wills, Karen Rowe

Journal of the Arkansas Academy of Science

The Roseatte Spoonbill (Platalea ajaja) is a rare bird in Arkansas and was not reported from the state until 1959, when it was seen in southwestern Arkansas. By use of online sources for citizen science, we elucidate the history of occurrence and present analysis of seasonal distribution of this bird in Arkansas. Individuals arrive in Arkansas as early as April, observations peak in August, and the birds may remain to late October when colder weather promotes southward migration. Most observations are of a few birds, but a maximum of 128 has been counted at one location and time. …


History, Distribution, And Reproduction By The Swallow-Tailed Kite (Elanoides Forficatus) In Arkansas, Grace Wills, C. Renn Tumlison Jan 2021

History, Distribution, And Reproduction By The Swallow-Tailed Kite (Elanoides Forficatus) In Arkansas, Grace Wills, C. Renn Tumlison

Journal of the Arkansas Academy of Science

The Swallow-tailed Kite (Elanoides forficatus) is a rare bird in Arkansas, and its historical populations are believed to have declined over much of the last century due to loss of bottomland hardwood forests and associated wetlands. However, sightings have increased in the recent 2 decades. By use of online sources for citizen science, we elucidate the current distribution of this bird in Arkansas, and comment on the status of reproduction. Swallow-tailed Kites arrive in Arkansas as early as March and remain to mid-September, but numbers of reported sightings have a bimodal occurrence with peaks in May and August.


Bird Usage Of Black Marasmius Fibers As Nest Material, Haris Rana, Shayla Smithson, Jack Jackson, Ragupathy Kannan Jan 2021

Bird Usage Of Black Marasmius Fibers As Nest Material, Haris Rana, Shayla Smithson, Jack Jackson, Ragupathy Kannan

Journal of the Arkansas Academy of Science

Black Marasmius fungal fibers have been frequently observed in neotropical bird nests. We tested to determine if superior tensile strength and temperature moderation contributes to why these fibers are preferred by some species over other available nesting materials. Marasmius fibers from nests of Yellow-olive Flycatchers (Tolmomyias sulphurescens) were compared to grass fibers from a Yellow-tailed Oriole (Icterus mesomelas) nest from the same area in Belize, Central America. We measured tensile strengths by a universal strength tester which stretched the fibers to their breaking point. We also used HOBO data loggers to compare the temperature differential between …

Exploring How Maternal Phosphorus Status Affects Calf Growth And Performance, Elizabeth Lafferty, Beth Kegley, Brittni Littlejohn, Jeremy Powell

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Phosphorus is an important component of bodily functions and is critical for adequate growth and development. This experiment evaluated the effect of maternal phosphorus intake on the growth and health of the calves. Treatments were 1) a free-choice mineral containing no supplemental P or 2) a free-choice mineral with 4% supplemental phosphorus. Primiparous, or pregnant for the first time, crossbred Angus beef cows (n = 36) were stratified by body weight and pregnancy status (bred by artificial insemination or natural service) then assigned to pasture groups (4 groups, 2/treatment, 9 heifers/group). These bred heifers had been receiving these same dietary …


Willingness-To-Pay For Halal And Branded Poultry In Northern Mozambique, Alison J. Creasey, L. Lanier Nalley Jan 2021

Willingness-To-Pay For Halal And Branded Poultry In Northern Mozambique, Alison J. Creasey, L. Lanier Nalley

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

While price typically drives consumers’ food-purchasing decisions in low-income countries, religious attributes associated with food production and corporate branding could influence buying patterns. In Mozambique, more than 46% of people were living below the poverty line of ($0.31 USD) per day in 2018. That being said, in the Nampula Province (the location of this study), which is the second poorest province in the country, over 25% of the population is Muslim and may be willing-to-pay (WTP) a premium for Halal meat products to uphold Islamic beliefs. Like many parts of sub-Saharan Africa, poultry is the fastest-growing source of protein. Since …
