Grazing Cover Crops For Soil Health In An Integrated Crop-Livestock System, Forrest E. Davis, J. Brett Rushing

IGC Proceedings (1977-2023)

. Optimizing soil health requires building an environment that creates conditions which allow for best function of the chemical, biological, and physical properties of the soil to thrive as an organism and an ecosystem. Integrated crop-livestock systems (ICLS) use a systems approach to provide improvements to soil health parameters. In the fall of 2021, a randomized complete block study was conducted at the Coastal Plain Branch Experiment Station (CPBES) in Newton, Mississippi and at the Prairie Research Unit (PRU) in Prairie, Mississippi to observe the soil health effects of grazing cereal rye cover crops in a soybean production system.

Short-Term Soil Organic Matter And Carbon Responses To Contrasting Grazing Intensities In Integrated Crop-Livestock Systems, Erick R. Da Silva Santos, Jose C. B. Dubeux, B. G. C. Homem, Cheryl L. Mackowiak, Lynn E. Sollenberger, D. Wright

IGC Proceedings (1977-2023)

Combining integrated crop-livestock systems under no-till management may improve soil organic matter (SOM) build up and improve soil C sequestration. Grazing cover crops appears as a possibility to combine crops and livestock in a farm system. Further SOM and soil C increase can be achieved by adding perennial grasses into crop rotations. However, the effect of grazing intensity in such systems are not fully understood. This 2-yr study investigated short-term effects of cropping system [winter cover crops-summer cotton (Gossypium hirsutum L.) and winter cover crops-summer bahiagrass (Paspalum notatum Flüggé) rotations], grazing intensity (no grazing, heavy, moderate, and light …

Productive Grasslands – The Role Of Adapted Species To Increase Ecosystems Resilience, M. B. Chiavegato, A. F. Mammana, C. Y. Rodriguez

IGC Proceedings (1977-2023)

Producers are interested in diversifying grazing systems with native warm-season grasses. Climate variations may result in extreme weather events. For instance, recent studies show strong evidence pointing to an increasing frequency of flooding in the central US, due to changes in both seasonal rainfall and temperature across this region. In a constantly changing climate, adapted species play a crucial role in increasing ecosystems resilience and resistance to extreme weather events. Native grasses may be well adapted to the future changes on climatic conditions, with wide ecological amplitude and resistance under different conditions. Use of adapted warm season grasses, associated with …

Revisiting The Use Of Normal Saline For Peritoneal Washing In Ovarian Cancer, Hironari Akasaka, Honami Naora

Faculty, Staff and Student Publications

The omentum is the predominant site of ovarian cancer metastasis, but it is difficult to remove the omentum in its entirety. There is a critical need for effective approaches that minimize the risk of colonization of preserved omental tissues by occult cancer cells. Normal saline (0.9% sodium chloride) is commonly used to wash the peritoneal cavity during ovarian cancer surgery. The omentum has a prodigious ability to absorb fluid in the peritoneal cavity, but the impact of normal saline on the omentum is poorly understood. In this review article, we discuss why normal saline is not a biocompatible solution, drawing …

Pmca Screening Of Retropharyngeal Lymph Nodes In White-Tailed Deer And Comparisons With Elisa And Ihc, Rebeca Benavente, J Hunter Reed, Mitch Lockwood, Rodrigo Morales

Faculty, Staff and Student Publications

Chronic wasting disease (CWD) is a prion disease affecting cervids. CWD diagnosis is conducted through enzyme-linked immunosorbent assay (ELISA) and immunohistochemistry (IHC) in retropharyngeal lymph nodes. Unfortunately, these techniques have limited sensitivity against the biomarker (CWD-prions). Two in vitro prion amplification techniques, real-time quaking-induced conversion (RT-QuIC) and protein misfolding cyclic amplification (PMCA), have shown promise in detecting CWD-prions in tissues and bodily fluids. Recent studies have demonstrated that RT-QuIC yields similar results compared to ELISA and IHC. Here, we analyzed 1003 retropharyngeal lymph nodes (RPLNs) from Texas white-tailed deer. PMCA detected CWD at a higher rate compared to ELISA/IHC, identified …
