Recognizing Power And Control When Planning Your Estate, Allan Vyhnalek 2023 University of Nebraska-Lincoln

Recognizing Power And Control When Planning Your Estate, Allan Vyhnalek

Cornhusker Economics

The older generations have spent their entire professional lives using the power and control that they accumulated through hard work and their long tenures. Having them retire and give up that control and power is difficult for some in those generations. Overall, it is challenging for them to give up control or power.


Conservation Agriculture And Cover Crop Adoption By Smallholder Farmers In Cambodia: Understanding Perceptions, Challenges, And Opportunities For Soil Improvement, Presley Nickens, David R. Ader, Max C. Miller, II, Pao Srean, Tom Gill, Sovanneary Huot 2023 University of Tennessee

Conservation Agriculture And Cover Crop Adoption By Smallholder Farmers In Cambodia: Understanding Perceptions, Challenges, And Opportunities For Soil Improvement, Presley Nickens, David R. Ader, Max C. Miller, Ii, Pao Srean, Tom Gill, Sovanneary Huot

Agricultural and Environmental Sciences Faculty Research

Practical solutions for soil conservation are needed to ensure sustainable food production. Conservation agriculture and the use of cover crops are promising strategies for soil improvement in agricultural systems. These strategies are being promoted in Cambodia to address rapidly declining soil fertility; however, there is a lack of insight into the perceptions of Cambodian smallholders towards cover cropping within a conservation agriculture approach. A greater understanding of the utilization and perceptions of cover crops is needed to increase adoption and prevent further soil degradation. This study utilized a mixed methods approach with quantitative data from a farmer survey and qualitative …

Liquid Chromatography Mass Spectrometry Method Development For The Determination Of Β–Defensins In Bovine Milk, Elisha Ogbebor 2023 Western Kentucky University

Liquid Chromatography Mass Spectrometry Method Development For The Determination Of Β–Defensins In Bovine Milk, Elisha Ogbebor

Masters Theses & Specialist Projects

Bovine mastitis is caused by a wide range of pathogens which results in a substantial economic loss for the dairy cattle livestock industry. β-defensins are a part of the innate immune system and act as the first line of defense against mastitis in bovine. β-defensins (~6- 10kDa) are antimicrobial peptides that contain about 28 to 67 amino acids, the presence of six cysteine residues results in their three disulfide bonds and a β-sheet structure. A few β- defensins have been identified in cows based on the site of occurrence and time of expression in tissue, but not in milk. A …


Towards The Quantification Of Estrone And 17Β-Estradiol Conjugates In Dairy Cattle Urine Sorptive Stir Bar Extraction And Gas Chromatography-Mass Spectometry, S.M. Istiak Ahmed 2023 Western Kentucky University

Towards The Quantification Of Estrone And 17Β-Estradiol Conjugates In Dairy Cattle Urine Sorptive Stir Bar Extraction And Gas Chromatography-Mass Spectometry, S.M. Istiak Ahmed

Masters Theses & Specialist Projects

The global concern regarding the presence of compounds with estrogenic properties in the environment has grown significantly. Endocrine-disrupting compounds (EDCs) are environmental pollutants that disrupt the endocrine systems of both wildlife and humans. Estrogens, with their potent estrogenic effects, are particularly noteworthy among the various substances with endocrine-disrupting properties. They are of concern due to their prevalence in the environment, especially due to dairy waste contamination. These lipophilic compounds can accumulate in livestock fat tissues, potentially entering the human food chain. Sulfated forms of estrone and β- estriol, which exhibit a higher degree of saturation than their non-conjugated counterparts, have …


Investigation Of Breeding Objectives And Indexes-In-Retrospect, Hunter F. Valasek 2023 University of Nebraska-Lincoln

Investigation Of Breeding Objectives And Indexes-In-Retrospect, Hunter F. Valasek

Department of Animal Science: Dissertations, Theses, and Student Research

This thesis presents two projects that investigate the impacts of breeding objectives and indexes-in-retrospect within the beef cattle industry. The first project synthesized how changes due to planning horizon, breeding system, and sale endpoint in the economic breeding goal of cattle influence the relative emphasis of traits as well as the re-ranking of selection candidates. A total of three breeding systems that represent straightbred and crossbred cattle were used along with six planning horizons (2, 5, 10, 20, 30, and 50 yrs.) for both a weaning and slaughter point of sale. The combination of these different breeding objective attributes resulted …

Arkansas Soybean Research Studies 2022, Jeremy Ross

Arkansas Agricultural Experiment Station Research Series

Arkansas is the leading soybean-producing state in the mid-southern United States. Arkansas ranked 11th in soybean production in 2022 when compared to the other soybean-producing states in the U.S. The state represented 3.04% of the total U.S. soybean production and 3.64% of the total acres planted in soybean in 2022. The 2022 state soybean average yield was 52.0 bushels per acre, tying the previous state yield record of 52 bushels per acre set in 2021. The top five soybean-producing counties in 2022 were Mississippi, Crittenden, Phillips, Poinsett, and Arkansas (Table 1). These five counties accounted for over 35.7% of the …


Feed Value And Utilization Of Corn Residue: Implications For Cow Performance And Grazing Strategies, Kaylee E. Wheeler 2023 University of Nebraska-Lincoln

Feed Value And Utilization Of Corn Residue: Implications For Cow Performance And Grazing Strategies, Kaylee E. Wheeler

Department of Animal Science: Dissertations, Theses, and Student Research

Two experiments were conducted to determine the correlation of corn residue feed value and utilization on cow performance and potential grazing strategies. A qualitative observation of corn residue grazing by 13 cattle herds across Nebraska was conducted over two years. Based on producer reported grain yields and stocking rates, it was found that these producers were generally not as aggressive as the recommended 1.2 animal unit months (AUM) for each 6,280 kg/ha (100 U.S. bushels/acre) of harvested grain. They stocked 17 to 101% of the recommendation and on average used 63% of the carrying capacity. Across herds, average body condition …

Turkish Journal of Agriculture and Forestry

Crop growth models can be valuable tools for researchers, academia, extension educators, and policy makers/planners for the evaluation of sustainable and long-term husbandry practices. Determining the optimum sowing window, which can be determined using crop growth models, is imperative under changing climate conditions. Thus, the main objectives herein were to 1) assess the performance of the cropping system model-crop environment resource synthesis-maize model for hybrids and sowing dates in the spring and autumn, and 2) determine the optimum sowing window in 15 districts of Punjab, Pakistan. In the spring experiment, 3 hybrids (P-33M15, M-DK6525, and S-NK8441) were planted in the …

Quercus ilex (Holm oak) presents itself as trees up to 14–15 m tall in suitable growing site conditions and as shrubs in unsuitable areas. The purpose of this study was to determine the relationships between tree-ring widths of Q. ilex and vessel features, tree diameters, climate, and site conditions throughout Türkiye. A total of 1020 cores from 510 trees were collected from 102 sampled sites throughout Türkiye. After using standard dendroclimatology methods, all tree-ring analyses were performed on these chronologies. As a result, tree-ring boundaries were found to be less visible in Türkiye, like in other Mediterranean areas. Mean sensitivity …

Turkish Journal of Agriculture and Forestry

Fresh blackberry fruits have easily perishable tissue and therefore have a very short postharvest storage life, although customers and marketers desire a longer shelf life. The ever-increasing demand of the world population for residue-free functional foods has motivated scientists to investigate environmentally friendly methodologies for the quality extension of perishable products like fresh blackberries. The present study was performed to determine the influences of UV-C treatment and chitosan coating on the extension of postharvest bioactive compounds and the marketable quality of fresh blackberry (Rubus fructicosus L.) fruits. Organically produced ‘Jumbo’ blackberry fruits were sorted into four equal groups for postharvest …
