Tetflupyrolimet is the first herbicide with a novel site of action (SOA) labeled PRE and early POST for use in agronomic crops to be labeled in the last three decades. Direct-seeded paddy rice field experiments were conducted near Stuttgart, AR, on a silt loam soil and near Keiser, AR, on a clay soil to evaluate tetflupyrolimet-containing herbicide programs in comparison to commercial standards in conventional, imidazolinone-resistant, and quizalofop-resistant rice systems. Additionally, a furrow-irrigated rice experiment was conducted near Colt, AR, and Keiser to ensure weed control with clomazone and tetflupyrolimet mixtures compared to commercial standards. Twelve commonly planted rice cultivars …

Crop, Soil and Environmental Sciences Faculty Publications and Presentations
Perennial crops are thought as a solution for enhancing food security and providing ecosystem services under a changing climate, including forage-biomass production, reduced erosion and nutrient leaching, and soil C accumulation. However, the drivers of root decomposition and C allocation in perennial multifunctional forage-biomass buffer-strips as affected by fertility management are poorly elucidated. Thus, study objectives were to assess root decomposition and soil CO2 efflux on switchgrass (Panicum virgatum L.), eastern gamagrass (Tripsacum dactyloides L.), silphium (Silphium integrifolium Michx.), and intermediate wheatgrass Kernza (Thinopyrum intermedium [Host] Barkworth & D.R. Dewey) treated with poultry litter (PL) relative to the unfertilized control. …

The goal of this research was to use supercritical carbon dioxide (SC-CO2) drying as a novel approach to generate sorghum protein concentrates with enhanced functional characteristics. Sorghum protein concentrates were extracted from white whole-grain sorghum flour and dried in two ways: freeze-drying and SC-CO2 drying. The dried proteins were characterized for their volatile compound content, in vitro digestibility, and amino acid composition. A more porous structure was observed for the SC-CO2-dried sorghum proteins compared with their freeze-dried counterparts. In the SC-CO2-dried samples, the levels of alcohols, esters, and organic acids were significantly lower than those in the freeze-dried ones, whereas …

BackgroundSow longevity and reproductivity are essential in the modern swine industry. Although many studies have focused on the genetic and genomic factors for selection, little is known about the associations between the microbiome and sows with longevity in reproduction.ResultsIn this study, we collected and sequenced rectal and vaginal swabs from 48 sows, nine of which completed up to four parities (U4P group), exhibiting reproductive longevity. We first identified predictors of sow longevity in the rectum (e.g., Akkermansia) and vagina (e.g., Lactobacillus) of the U4P group using RandomForest in the early breeding stage of the first parity. Interestingly, these bacteria in …

Kinetics Of Protein And Amino Acids, S. Y. Liu, M. Toghyani, S. P. Macelline, P. H. Selle
Proceedings of the Arkansas Nutrition Conference
Protein and amino acid nutrition is key to poultry growth and sustainability, with synchrony between glucose and amino acid availability being critical for efficient feed conversion. While non-bound amino acids (NBAA) are rapidly absorbed and increasingly used to reduce crude protein levels, their fast uptake may disrupt amino acid balance and reduce nutrient utilization compared to protein-bound amino acids. Future research should redefine amino acid requirements in low-CP diets, explore the metabolic fate of NBAA, and investigate how protein sources affect gut microbiota and host metabolism.

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 …

This study explored the benefits of nature-based pediatric occupational therapy (OT) and the influence of nature and nature-based play on fine motor development. It was hypothesized that nature and nature-based play would positively impact a child’s fine motor skills (FMS) and that nature-based OT would offer unique benefits to a child’s therapeutic experience. To examine these relationships, a survey was distributed to pediatric occupational therapists (OTs) across the United States. The survey was designed to gather insights into how OT supports fine motor development, how nature-based play/therapy enhances these skills, and the perceived benefits of incorporating nature into therapeutic practices. …

With the continued increase of fertilizer prices, stocker cattle producers may utilize alternative management strategies to mitigate costs and extend the grazing season to achieve better utilization of a wheat (Triticum aestivum L.) crop. One potential strategy is to reduce pasture nitrogen (N) fertilization rates combined with animal dietary supplementation. In this 3-year (yr) study, wheat pastures (1.62-hectare (ha)) were stocked at fixed rates of 2.47 and 4.94 steer/ha in the fall and spring respectively. Nitrogen was applied as urea to experimental pastures at three different rates: 1) 100.9 (100N), 2) 134.5 (135N), and 3) 168.1 kg N/ha (168N). These …

Assessing The Prevalence Of Ehrlichia Spp. In Ticks Associated With Canids In Arkansas, Eva Berryhill, Kelly Loftin
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Canine ehrlichiosis is a common disease seen in dogs. The southeastern United States has been identified as an area of high prevalence, including Arkansas. Changes in climate, household income, and tick population are factors contributing to high prevalence. Canine ehrlichiosis is caused by three Ehrlichia spp., which are E. canis, E. ewingii, and E. chaffeensis. Ticks transmit the pathogen, specifically Rhipicephalus sanguineus, Dermacentor variabilis, and Amblyomma americanum. For this study, the goal was to determine the prevalence of Ehrlichia spp. in Arkansas that causes canine ehrlichiosis. Ticks were collected from host canines and environmental …

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.

Chick sexing, the process of determining the gender of day-old chicks, is a critical task in the poultry industry due to the distinct roles that each gender plays in production. While effective traditional methods achieve high accuracy, color, and wing feather sexing is exclusive to specific breeds, and vent sexing is invasive and requires trained experts. To address these challenges, we propose a novel approach inspired by facial gender classification techniques in humans: facial chick sexing. This new method does not require expert knowledge and aims to reduce training time while enhancing animal welfare by minimizing chick manipulation. We develop …
