Alfalfa (Medicago sativa L.) is a globally vital forage crop valued for its perennial growth and multiple annual harvests. A breeding effort is underway to improve the crop for productivity and persistence against biotic and abiotic stresses using “creeping rootedness,” a trait where plants exhibit horizontal root growth, similar to rhizomes, with increased vegetative ground surface area. In this study, we genotyped a breeding population of 648 alfalfa lines segregating for creeping rootedness using the 3K DArTag marker panel to identify trait-associated genomic loci and evaluate the feasibility of genomic prediction to accelerate breeding cycles. Using genome-wide association studies …

Weaning Beef Calves, David Secrist

All Current Publications

Weaning a beef calf is likely the most stressful event in the animal’s life. Future growth and reproductive performance can be compromised by health challenges encountered through the weaning process. Consequently, proper management aimed at reducing stress and preparing the beef animal for the next stage of production is critical to reach its genetic potential. Proper management involves applying good animal husbandry techniques, using sound science in developing health and feeding protocols, and implementing low-stress animal handling practices.

Browse all Datasets

Background/Objectives: Chronic inflammation and Western-style diets elevate colorectal cancer (CRC) risk, particularly in individuals with colitis, a feature of inflammatory bowel disease (IBD). Diets rich in polyphenol-containing functional foods, such as cocoa, may reduce gut inflammation and modulate the gut microbiome. This study examined the effects of cocoa polyphenol (CP) supplementation on inflammation and microbiome composition before, during, and after colitis in mice fed either a healthy or Western diet. We hypothesized that CPs would attenuate inflammation and promote distinct micro-biome shifts, especially in the context of a Western diet. Methods: A 2×2 factorial design tested the effects of basal …

A Review Of Plant–Microbe Interactions In The Rhizosphere And The Role Of Root Exudates In Microbiome Engineering, Anagha Wankhade, Emma Wilkinson, David W. Britt, Amita Kaundal

Biological Engineering Student Research

Microbial interactions within the rhizosphere are fundamental to plant health, influencing nutrient availability, stress tolerance, and pathogen resistance. Beneficial microbes, such as plant growth-promoting microbes (PGPMs), including bacteria and mycorrhizal fungi, enhance plant resilience through mechanisms like nutrient solubilization, phytohormone production, and pathogen suppression via antimicrobial compounds and siderophores. Root exudates, composed of sugars, organic acids, and secondary metabolites, act as chemoattractants that shape the rhizosphere microbiome by recruiting beneficial microbes. Microbial metabolites can, in turn, modulate plant physiology and exudate profiles, thereby reinforcing mutualistic interactions. Stress conditions alter exudate composition, enabling plants to attract specific microbes that aid in …

Influence Of Age At Harvest And Packaging Conditions On Color Stability Of Bovine Psoas Major Muscle, Xiao Lu, Xin Luo, Sulaiman K. Matarneh

Nutrition, Dietetics, and Food Science Student Research

This study investigated the effect of cattle age on the color stability of Psoas major steaks under different packaging conditions, including polyvinyl chloride (PVC) film packaging, high-oxygen-modified atmosphere packaging (HiOx-MAP), and carbon monoxide modified atmosphere packaging (CO-MAP), over a 14-day storage period. Steaks from old cows had a greater myoglobin content than those from young animals (p < 0.05), resulting in a darker beef color. Regardless of animal age, steaks in PVC and HiOx-MAP exhibited poor color stability during storage, as evidenced by the low color intensity and high surface metmyoglobin (MetMb; p < 0.05). These samples also exhibited a reduced MetMb reducing activity (MRA) and oxygen consumption rate (OCR) and higher 2-thiobarbituric acid reactive substance (TBARS) levels, with these effects being evident in steaks from mature cows. In contrast, steaks stored in CO-MAP had greater redness, MRA, and OCR, along with lower surface MetMb and TBARS levels (p < 0.05), contributing to the limited discoloration of steaks from both age groups. These findings suggest that while both harvest age and packaging affect the shelf stability of bovine steaks, packaging plays a more significant role. CO-MAP proved to be more effective than aerobic packaging and may mitigate age-related differences in color stability.

1. Ecological responses to climate change occur across vastly different time-scales, from minutes for physiological plasticity to decades or centuries for community turnover and evolutionary adaptation. Accurately predicting the range of ecosystem trajectories will require models that incorporate both fast processes that may keep pace with climate change and slower ones likely to lag behind and generate disequilibrium dynamics. However, the knowledge necessary for this integration is currently fragmented across disciplines.

2. We develop ‘ecological acclimation’ as a unifying framework to emphasize the similarity of dynamics driven by processes operating on dramatically different time-scales and levels of biological organization. The …

Potential Epigenetic Impacts Of Phytochemicals On Ruminant Health And Production: Connecting Lines Of Evidence, Sebastian P. Schreiber, Juan Villalba, Mirella L. Meyer-Ficca

Wildland Resources Student Research

The once mysterious “dark matter of nutrition”, comprising countless plant derived secondary compounds, also known as phytochemicals, is now understood to have significant and wide-ranging effects on consumers, including myriad health benefits in humans and livestock. The selective consumption of phytochemically rich and diverse plants, in appropriate doses, by ruminants represents an adaptive means of therapeutic and prophylactic self-medication. Due to their chemical structure, phytochemicals have long been recognized as antioxidants. However, the mechanisms that underlie numerous additional phytochemical-based health benefits are generally less understood. These effects (i.e., anti-inflammatory, immunomodulatory, and anticarcinogenic effects) are likely related to epigenetic processes. Evidence …
