Energy Metabolism In Jersey Cows: Improving Our Understanding Of Energy Requirements And Utilization, Dennis Morris

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

Energy is the most limiting nutrient for high producing lactating dairy cows and improving our understand of factors affecting energy supply should improve our ability to estimate net energy of lactation (NE_L), milk production, and tissue accretion. To achieve this object, firstly, three experiments were completed to determine 1) maintenance energy requirements; 2) factors affecting heat production; and 3) the relationship between urinary N and energy excretion. Three additional experiments using lactating Jersey cows were completed to evaluate energy utilization of diets varying in 1) supply of Lys and His; 2) fatty acids (FA) and …

Estimating Economic Minimums Of Mowing, Fertilizing, And Irrigating Turfgrass, Douglas J. Soldat, James T. Brosnan, Ambika Chandra, Roch E. Gaussoin, Alec Kowalewski, Bernd Leinauer, Frank S. Rossi, John C. Stier, J Bryan Unruh

Department of Agronomy and Horticulture: Faculty Publications

The public health crisis and economic recession caused by the COVID-19 pandemic have forced turfgrass industry professionals to re-evaluate standard practices. Minimum costs required to fertilize, irrigate, and mow turfgrasses can be roughly estimated using climate data, turfgrass physiology information, and resource costs. Although the actual minimum costs vary situationally and regionally, mowing golf putting greens optimally requires about US$34 per acre per month, whereas other turfgrass areas cost less than US$11 per acre per growing month. Fertilizer applications to turfgrass cost US$22 or less per acre per growing month. Irrigation costs (water and electricity for pumping) vary widely, with …

2020 Nebraska Property Tax Changes, J. David Aiken

Cornhusker Economics

The Nebraska Unicameral enacted significant property tax relief legislation in the closing days of the 2020 legislative session. The last-minute compromise was negotiated by seven legislators selected by the Speaker. The compromise estab-lishes a refundable state income tax credit of an estimated 6% of the property taxes paid for local schools (excluding property taxes for school bonds and school budget overrides). Taxpayers will be able to claim this credit on next year’s Ne-braska state income tax return. For fiscal years (FYs) 2021-22 through 2023-24 (i.e. from July 1, 2021, through June 30, 2024), the amount availa-ble for the refundable state …

Aspen Bibliography

Based on a generated database of 413 sample plots, with definitions of stand biomass of the genus Populus spp. in Eurasia, from France to Japan and southern China, statistically significant changes in the structure of forest stand biomass were found, with shifts in winter temperatures and average annual precipitation. When analyzing the reaction of the structure of the biomass of the genus Populus to temperature and precipitation in their transcontinental gradients, a clearly expressed positive relationship of all components of the biomass with the temperature in January is visible. Their relationship with precipitation is less clear; in warm climate zones, …

Analyzing The Longevity Of Sperm Within The Female Japanese Quail By Assessing Sperm Penetration Of The Perivitelline Layer Under Optimal And Suboptimal Conditions., Garret G. Ashabranner, Joey L. Bray

Electronic Theses and Dissertations

After mating, birds have the ability to store semen within the female reproductive tract. The sperm storage tubules will store and subsequently release semen to travel up the oviduct. Sperm cells that make the trek up the oviduct have a chance to fertilize the ovum. These sperm cells will bind to the perivitelline layer of the ovum and hydrolyze a hole in the perivitelline layer, where it has the possibility to fertilize the female sex cell. Analyzing the number of penetration points on the perivitelline layer is an effective way to analyze reproductive efficiency. Many environmental factor has its effect …

Substrate Properties And Fertilizer Rates On Yield Responses Of Lettuce In A Vertical Growth System, Zadarreyal Wiggins, Onyekachukwu Akaeze, Dilip Nandwani, Anthony Witcher

Agricultural and Environmental Sciences Faculty Research

The increased demand for food and the challenge for space for agriculture production in urban centers have made the vertical growth system an interesting trend. Agriculture is no longer only the horizontal, traditional, and soil grown method. Urban agriculture has created ways for inner city growers to be able to farm in a restricted space. Vertical farming is the practice of growing crops, especially leafy vegetables such as lettuce, in vertically stacked layers, as this results in significantly higher plant population per unit area. Two research trials were conducted in the fall of 2018 and the spring of 2019 to …

Soybean Barcsoysnp6k: An Assay For Soybean Genetics And Breeding Research, Qijian Song, Long Yan, Charles Quigley, Edward Fickus, He Wei, Linfeng Chen, Faming Dong, Susan Araya, Jinlong Liu, David Hyten, Vincent R. Pantalone, Randall L. Nelson

Department of Agronomy and Horticulture: Faculty Publications

The limited number of recombinant events in recombinant inbred lines suggests that for a biparental population with a limited number of recombinant inbred lines, it is unnecessary to genotype the lines with many markers. For genomic prediction and selection, previous studies have demonstrated that only 1000–2000 genome-wide common markers across all lines/accessions are needed to reach maximum efficiency of genomic prediction in populations. Evaluation of too many markers will not only increase the cost but also generate redundant information. We developed a soybean (Glycine max) assay, BARCSoySNP6K, containing 6000 markers, which were carefully chosen from the SoySNP50K assay based …

Department of Agronomy and Horticulture: Faculty Publications

Alfalfa (Medicago sativa L.) is one of the most important forage crops throughout the world. Maximizing leaf retention during the haymaking process is critical for achieving superior hay quality and maintaining biomass yield. Leaf abscission process affects leaf retention. Previous studies have largely focused on the molecular mechanisms of floral organ, pedicel and seed abscission but scarcely touched on leaf and petiole abscission. This study focuses on leaf and petiole abscission in the model legume Medicago truncatula and its closely related commercial species alfalfa. By analysing the petiolule-like pulvinus (plp) mutant in M. truncatula at phenotypic level (breakstrength and shaking …

Cares Act Implications On Tax Planning For Farmers, Tina N. Barrett

Cornhusker Economics

The CARES Act, passed in March of 2020, provid-ed many changes that directly impacted farmers. It created both the Payroll Protection Program (PPP) and Economic Injury Disaster Loans (EIDL), which many farmers utilized. However, the CARES Act included several other provisions that didn’t get as much attention. Farmers need to be aware of these as they go into tax planning this fall, as they could benefit their operations.
