Effects Of Late Gestation Supplementation And Creep Feeding On Spring Calving Beef Cows In The Nebraska Sandhills, Devin Broadhead

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

The objectives of this research were to 1) evaluate the effects of late gestation supplementation, synchronization and creep feeding on cow and calf production traits 2) evaluate the pooled effects of 5 studies involving late gestation supplementation on cow and calf traits. Experiment 1 was a three year study conducted on 8 pastures at the Gudmundsen Sandhills Laboratory. Cows were assigned to 1 of 4 late-gestation supplementation treatments, postpartum progestin or control, and 1 of 2 creep feed treatments to make up a 4 x 2 x 2 factorial arrangement. Calves were followed through to slaughter.

Experiment 2 involved 5 …

Assessment Of Watersheds For Sustainable Agriculture In Karnataka, India, Nicholas Adam Charles

FIU Electronic Theses and Dissertations

Modernization of traditional small-scale irrigation tanks in India is becoming increasingly popular. This is due to high costs of the alternative, of developing and constructing large-scale projects in rural areas. Examination of management strategies, resource allocation, and collective action has become paramount for promoting food security and livelihoods in water-stressed areas of Southeast Asia. Geographic Information System (GIS) and Remote Sensing techniques are valuable to assessing the management of these irrigation systems, specifically small water storage reservoirs that capture runoff from the monsoon known as irrigation tanks. The primary goal of this study is to develop a stakeholder-informed approach to …

An Economic Feasibility Assessment Of Autonomous Field Machinery In Grain Crop Production, Jordan Murphy Shockley, Carl R. Dillon, Scott A. Shearer

Agricultural Economics Faculty Publications

A multi-faceted whole farm planning model is developed to compare conventional and autonomous machinery for grain crop production under various benefit, farm size, suitable field day risk aversion, and grain price scenarios. Results suggest that autonomous machinery can be an economically viable alternative to conventional manned machinery if the establishment of intelligent controls is cost effective. An increase in net returns of 24% over operating with conventional machinery is found when including both input savings and a yield increase due to reduced compaction. This study also identifies the break-even investment price for intelligent controls for the safe and reliable commercialization …

When people talk about the future of Appalachia, they typically mean economic futures: What will happen to coal jobs? How will Appalachia diversify its economy? What about poverty? Stereotypes about our region represent our people as disinterested in education, and hostile to innovation, technology, and sustainability. We see a different story. This part of the exhibit looks at ways that Appalachians are taking their strong sense of culture, their linguistic distinctiveness, and their relationship to the natural world to imagine new futures in diverse industries, sustainable practices, and stronger education systems.
