Low Protein Diet Strategy, S. Y. Liu, P. V. Chrystal, M. T. Kidd, M. Toghyani, S. P. Macelline, P. H. Selle

Proceedings of the Arkansas Nutrition Conference

Reduced crude protein (CP) diets can lower nitrogen excretion and improve litter quality, but their effectiveness varies depending on the grain type, with wheat-based diets often showing poorer broiler performance compared to maize or sorghum. The digestive dynamics and synchrony between NBAA and protein-bound amino acids, along with starch-to-protein ratios, influence feed efficiency and fat deposition, which remains a challenge in reduced CP diets. Optimizing amino acid supplementation and exploring alternative protein-rich ingredients may help improve outcomes, especially in regions with limited access to soybean meal.

Ms Environmental Biology Capstone: Evaluating Environmental Risks And Conflicts In Golf Course Landscapes, Meredith Boos

Regis University Student Publications (comprehensive collection)

1) This review investigates the relationship between pesticide use on golf courses and in agriculture to determine whether the adverse health effects documented in agricultural settings also apply to golf course environments. While the negative health effects from agricultural pesticide use are well established, golf courses use pesticides with greater frequency and intensity, suggesting a potentially higher exposure risk for both workers and players.

2) This study proposes methods to quantify pesticide bioaccumulation on golf courses and adjacent lands. We hypothesize that areas surrounding golf courses will exhibit a spatial gradient of pesticide accumulation, increasing with proximity to treated sites …

Layer Industry Update: Nutrition Associated With Changes In Production Systems, Kenneth E. Anderson, Ishab Poudel

Proceedings of the Arkansas Nutrition Conference

This is not a hardcore research presentation but rather an overview of three North Carolina Layer Performance and Management Tests. I used the 39th, 40th, and 41st Layer Test Reports that cover the years 2013 through 2025. The proceedings cover white and brown egg strains as groups and the cage and cage-free production environments. Over all three of these tests the production environments were the same and met UEP Cage standards and the Humane Farm Animal Care cage-free standards. There are papers outlining the changes in more detail with all the statistics. This is an overview of visual trends in …

Field Experience And Production Challenges In Australia And New Zealand, Nick Rodgers

Proceedings of the Arkansas Nutrition Conference

Variability management represents the primary technical challenge facing the Australian and New Zealand (ANZ) broiler industry's vertically integrated operations. This analysis examines systematic approaches to controlling seasonal performance fluctuations, raw material quality variations, emerging disease pressures, and evolving welfare demands. Key variability sources include climatic extremes, season to season raw material quality and nutrient value variability and intermittent [mostly enteric] disease challenges, particularly in no antibiotics ever (NAE) production systems. Solutions require a scientific, data-driven approach with insights from field experience for causation identification and a collaborative approach within business functional units, and across industry collaborators such as suppliers and …

Pygoscelis Penguins Prefer Different Oceanographic And Terrestrial Habitats During The Austral Summer, Katherine L. Gallagher, Rachel Herman, Katherine Walton, Michael S. Dinniman, Heather J. Lynch

OES Faculty Publications

Pygoscelis penguins interact with both terrestrial and marine environments, especially during the austral summer when they raise their chicks. Accessible ice-free ground spaces serve as locations for penguins to build colonies and successfully raise chicks while the surrounding marine environment serves as the foraging grounds for adult birds. Penguins must be able to navigate through the waters around their colonies to forage for Antarctic krill (Euphausia superba), their primary prey during the austral summer. Krill, whose distributions are driven partially by the surrounding physics and partially by their behaviors, must also be plentiful in the waters near the …

Utilization Of Golden Pennycress In Broiler Diets, Marley M. Knowles

Theses and Dissertations

The objective of this study was to evaluate performance in broiler chickens fed diets containing golden pennycress meal (GPCM), with and without a flavor additive. Golden pennycress (Thlaspi arvense) is a winter cover crop grown in the Midwest that is rising in popularity as a cash crop used for biofuel production. After oil is pressed out of the seeds, a meal remains that is usually discarded. Incorporation of this meal (23% protein, 15% fat) into feedstuffs for broilers would be an efficient way to make biofuel production more sustainable. In one study, Cornish Cross three-day-old chicks (n=12) were …

Leukocyte Infiltration Profiles At The Site Of Intradermal Injection Of Silikon-1000 In Scleroderma-Prone Ucd200/206 And Healthy White Leghorn Chickens, Katee L. Johnson, Jossie M. Santamaria, Chrysta N. Beck, Gisela F. Erf

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

Intradermal injections of silicone-based fillers for the face and body may cause chronic inflammation and fibrotic reactions in some individuals. Chickens from the UCD 200/206 White Leghorn (WL) line spontaneously develop a fibrotic autoimmune disease known as scleroderma/systemic sclerosis (SSc). Using the SSc-prone UCD and healthy WL chickens, a longitudinal study was conducted to examine the cellular inflammatory responses to intradermal (i.d.) injections of sterile SILIKON-1000. Specifically, the pulp (a skin derivative) of growing feathers (GFs) was i.d. injected with sterile SILIKON-1000 or phosphate-buffered saline (PBS) as injection control (8 and 3 birds/line, respectively; 10 µL/GF; 20 GFs/bird). Two GFs …

Identification Of Salt Tolerance And Stress Response In Us Department Of Agriculture Tomato Germplasm At The Seedling Stage, Ibtisam Alatawi, Haizheng Xiong, Kenani Chiwina, Hanan Alkabkabi, Qun Luo, Neelendra K. Joshi, Xiaolun Sun, Xuan Zhuang, Kai-Shi Ling, Ainong Shi

Horticulture Faculty Publications and Presentations

Soil salinity is a significant abiotic factor that impedes sustainable crop production in key agricultural regions worldwide. Saline cultivation adversely affects soil quality, whereas the use of saline water for irrigation disrupts the physiological and biochemical processes of plants. Continuous irrigation with high salt concentrations leads to a gradual buildup of soil salinity, thus hindering optimal plant growth and development. Consequently, there is a growing emphasis on breeding salinity-tolerant cultivars of various crops. In this study, 71 tomato accessions sourced from 20 countries and provided by the US Department of Agriculture were evaluated under controlled greenhouse conditions and subjected to …

The broiler industry in the US has observed a consistent decline in fertility and hatchability, particularly the past 5 years. There are numerous managerial and nutritional approaches to optimize the pullet and subsequent mature broiler breeder, and these proceedings focus on feathering. Moreover, these proceedings examine the quantity and quality of broiler breeder plumage as affected by both pullet and hen nutrition.

Climate Change Affecting Waterfowl Migration, Destiny Fox

D.U.Quark

Climate Change is a major environmental factor in waterfowl migration patterns. Migratory waterfowl are species of birds that live in or around wetlands, mainly including lakes, streams, and marshes. Contaminated bodies of water at stopover sites during migratory seasons can lead to death among many species of waterfowl, as well as water borne diseases from snail eggs. Changing environmental factors can also lead to negative effects on the bird’s ability to forage properly. These environmental factors include the evaporation of several wetlands that have led to waterfowl foraging in local farmers’ land. Focusing more heavily on improving satellite tracking could …

Providing Proteins To Belizean Residents Through Poultry Products, Ellis Freel

Poultry Science Undergraduate Honors Theses

Belize is a food insecure, developing country. Although Belize has plenty of nutritious food in-country, the exportation of that food to generate income contributed to a distribution issue of that nutritious food. More impoverished areas of Belize do not have access to nutritious food because of the lack of affordability and high export rates. Diets with a lack of food, or lack of balanced, nutritious food can negatively impact growth and cognitive development, especially in children. Poultry is one of the only products in Belize not able to be exported. Implementing poultry into Belizean diets would affordably alleviate food insecurity …

First Breeding Confirmation For Red-Breasted Nuthatch (Sitta Canadensis) Along The Big Bend Reach Of The Platte River, Jacob C. Cooper, Cody Mcgregor, Letitia M. Reichart, Janet Steele

Nebraska Bird Review

The Red-breasted Nuthatch (Sitta canadensis) is a highly nomadic species of North American nuthatch prone to large movements across the entire continent (Ghalambor and Martin 2020). This behavior has resulted in both a lack of geographic variation across the continent and propensity to colonize isolated patches of suitable habitat (Ghalambor and Martin 2020). In the Bessey District of the Nebraska National Forest (NNF), Red-breasted Nuthatches were one of the first coniferous-forest bird species to colonize and begin breeding in the isolated planted stands of pine (Zimmer 1913, Bray 1994). Despite the increasing number of records for the species …

Fall Field Report, August–November 2024, W. Ross Silcock

Nebraska Bird Review

First off, I should reiterate that records are only mentioned in this Introduction and in the text when they add to or fine-tune data included in BONO (Birds of Nebraska – Online (outdoornebraska.gov). It was my expectation that as the number of birders and in particular those reporting to eBird continue to increase, gaps in the database will be filled and my job will become simpler. However, this expectation is yet to be realized, likely due to increasing movements and activity among birds that appears to be due to increasing severity of weather events, such as heat, cold, and drought, …
