A Population Dynamics Tipping Point For Aging As A Cause Of Adult Death, Andrea Scharf Jan 2021

A Population Dynamics Tipping Point For Aging As A Cause Of Adult Death, Andrea Scharf

Biological Sciences Faculty Research & Creative Works

Populations are a fundamental level of biological organization that poses major challenges for analysis. Individual traits that influence development, diapause, reproduction, aging, and lifespan interact in complex ways to determine birth and death. Birth and death drive population dynamics and determine whether a population survives or is doomed for extinction. However, we lack a deep understanding of the relationships between individual traits and population dynamics, a major challenge in the emerging field of ecology-development (eco-devo). Here we establish a laboratory ecosystem using the model organism C. elegans and a computational simulation that realistically models the laboratory ecosystem. We used these …

An Environmental Assessment Of Cattle Manure And Urea Fertilizer Treatments For Corn Production In The Northern Great Plains, C. Alan Rotz, Senorpe Asem-Hiablie, Erin Cortus, Mindy J. Spiehs, Shafiqur Rahman, Anne Stoner

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Nitrogen (N), phosphorus (P), and carbon (C) emissions from livestock systems have become important regional, national, and international concerns. Our objective was to use process-level simulation to explore differences among manure and inorganic fertilizer treatments in a corn production system used to feed finishing cattle in the Northern Great Plains region of the U.S. Our analysis included model assessment, simulation to compare treatments under recent climate, and comparisons using projected midcentury climate. The Integrated Farm System Model was evaluated in representing the performance and nutrient losses of corn production using cattle manure without bedding, manure with bedding, urea, and no …

Use Of Bedding Materials In Beef Bedded Manure Packs In Hot And Cool Ambient Temperatures: Effects On Ammonia, Hydrogen Sulfide, And Greenhouse Gas Emissions, Jeff P. Jaderborg, Mindy J. Spiehs, Bryan L. Woodbury, Alfredo Dicostanzo, David B. Parker

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Throughout the Upper Midwest, producers have observed increased land and fertilizer prices, resulting in increased popularity of confinement feeding facilities such as mono-slope and hoop barns with bedded packs. Environmental and public pressure has been placed on the agriculture community to reduce ammonia (NH3), hydrogen sulfide (H2S), and greenhouse gas (GHG) emissions from concentrated animal feeding operations (CAFOs). This study was conducted to determine the effects of bedding material (corn stover (CS), bean stover (BS), wheat straw (WS), or pine wood chips (PC)) and ambient temperature (15°C (COOL) or 30°C (HOT)) on NH3, CH4, CO2, N2O, and H2S flux in …

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Johne’s disease is a chronic, contagious, zoonotic disease that affects numerous species including livestock and sometimes humans. The disease is globally distributed in sheep populations and caused by Mycobacterium avium Subsp. paratuberculosis (MAP). A previous genome-wide association study identified single nucleotide polymorphism (SNP) markers associated with OJD serostatus in CD109, PCP4, and SEMA3D genes. Our aim was to evaluate the same markers for association with OJD seroprevalence in Turkish sheep in a retrospective matched case-control study. The serological status for OJD in 1801 sheep was determined for four native and four composite breeds from three research flocks. One hundred eleven …

Comparison Of Performance Of F1 Romanov Crossbred Ewes With Wool And Hair Breeds During Spring Lambing Under Intensive And Extensive Production Systems, Brad A. Freking, Thomas W. Murphy

Roman L. Hruska U.S. Meat Animal Research Center: Reports

The objective was to evaluate wool (Dorset and Rambouillet) and hair (Dorper, Katahdin, and White Dorper) breeds for their ability to complement Romanov germplasm in two distinct production systems by estimating direct sire and grandsire effects on lamb growth, survival, and ewe productivity traits. Rams of the five breeds (n = 75) were mated to Romanov ewes (n = 459) over a 3-yr period to produce five types of crossbred lambs (n = 2,739). Sire breed (P > 0.06) did not impact body weight or survival traits of the first-generation crossbred (F1) lambs. The productivity of retained crossbred ewes (n = …


Accuracy Of Gebv Of Sires Based On Pooled Allele Frequency Of Their Progeny, Napoleón Vargas Jurado, Larry A. Kuehn, John W. Keele, Ronald M. Lewis Jan 2021

Accuracy Of Gebv Of Sires Based On Pooled Allele Frequency Of Their Progeny, Napoleón Vargas Jurado, Larry A. Kuehn, John W. Keele, Ronald M. Lewis

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Despite decreasing genotyping costs, in some cases individually genotyping animals is not economically feasible (e.g., in small ruminants). An alternative is to pool DNA, using the pooled allele frequency (PAF) to garner information on performance. Still, the use of PAF for prediction (estimation of genomic breeding values; GEBVs) has been limited. Two potential sources of error on accuracy of GEBV of sires, obtained from PAF of their progeny themselves lacking pedigree information, were tested: (i) pool construction error (unequal contribution of DNA from animals in pools), and (ii) technical error (variability when reading the array). Pooling design (random, extremes, K-means), …

Roman L. Hruska U.S. Meat Animal Research Center: Reports

When the number of horn flies that blood feed on cattle exceeds the economic threshold, they can adversely affect the health and wellbeing of their hosts. Excessive horn fly burdens also lead to reduced weight gain and, consequently, diminished profits for livestock producers. Effective management and treatment require reliable surveillance methods for estimating the degree of horn fly burden (i.e., counting the number of flies on cattle). Traditionally, these estimates are obtained through human visual estimation, either in-person or by counting images on a photo; however, these methods are costly both in terms of time and labor and are prone …

Use Of Bedding Materials In Beef Bedded Manure Packs At Hot And Cold Ambient Temperatures: Effects On Odorous Volatile Organic Compounds And Odor Activity Values, Jeff P. Jaderborg, Mindy J. Spiehs, Bryan L. Woodbury, Alfredo Dicostanzo, David B. Parker

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Beef cattle producers are beginning to raise cattle in confinement facilities such as slatted-floor barns, hoop barns, and mono-slope facilities. Hoop and mono-slope facilities typically use bedding packs as part of their manure management system, with crop residues being the most commonly used bedding material. This study was conducted to determine the effects of bedding material, i.e., corn stover (CS), bean stover (BS), wheat straw (WS), or pine wood chips (PC), and environmental ambient temperature, i.e., cold (15°C) or hot (30°C), on the concentrations of odorous volatile organic compounds (VOCs) in air samples collected in the headspace above lab-scale bedded …

Hepatoenteric Recycling Is A New Disposition Mechanism For Orally Administered Phenolic Drugs And Phytochemicals In Rats, Yifan Tu, Lu Wang, Yi Rong, Vincent Tam, Taijun Yin, Song Gao, Rashim Singh, Ming Hu

Faculty Publications

Many orally administered phenolic drugs undergo enterohepatic recycling (EHR), presumably mediated by the hepatic phase II enzymes. However, the disposition of extrahepatically generated phase II metabolites is unclear. This paper aims to determine the new roles of liver and intestine in the disposition of oral phenolics. Sixteen representative phenolics were tested using direct portal vein infusion and/or intestinal perfusion. The results showed that certain glucuronides were efficiently recycled by liver. OATP1B1/1B3/2B1 were the responsible uptake transporters. Hepatic uptake is the rate-limiting step in hepatic recycling. Our findings showed that the disposition of many oral phenolics is mediated by intestinal glucuronidation …

To mimic Alzheimer's disease, transgenic mice overexpressing the amyloid precursor protein (APP) were used in this study. We hypothesize that the neuroprotective effects of ETAS®50, a standardized extract of Asparagus officinalis stem produced by Amino Up Co., Ltd. (Sapporo, Japan), are linked to the inhibition of the apoptosis cascade through an enhancement of the stress-response proteins: heat shock proteins (HSPs). APP-overexpressing mice (double-transgenic APP and PS1 mouse strains with a 129s6 background), ages 6-8 weeks old, and weighing 20-24 grams were successfully bred in our laboratory. The animals were divided into 5 groups. APP-overexpressing mice and wild-type (WT) mice were …

A recent surge in the use and abuse of diverse prescribed psychotic and illicit drugs necessitates the surveillance of drug residues in source water and the associated ecological impacts of chronic exposure to the aquatic organism. Thirty-six psychotic and illicit drug residues were determined in discharged wastewater from two centralized municipal wastewater treatment facilities and two wastewater receiving creeks for seven consecutive days in Kentucky. Zebrafish (Danio rerio) larvae were exposed to the environmental relevant mixtures of all drug residues, all illicit drugs, and all prescribed psychotic drugs. The extracted RNA from fish homogenates was sequenced, and differentially …


Science Of Climate Change In Agricultural Courses, Iin P. Handayani Jan 2021

Science Of Climate Change In Agricultural Courses, Iin P. Handayani

Faculty & Staff Research and Creative Activity

Climate change adaptation is required knowledge for students and graduates from colleges of agriculture since recent crop production and food security are influenced by climate change. Thus, understanding the dynamics of climate change is important to support farmers to adapt to future conditions. However, not all students and graduates understand the concept and application of climate change with regard to the dynamics of food production and future food security. While agriculture faces the challenge of climate change adaptation, agricultural courses have not kept pace by incorporating climate change science into the curricula. To address this issue, eleven syllabi in selected …
