Assessment Of Ruminal Fermentation Characteristics Of Condensed Tannin-Containing Forages Using Continuous Cultures, Christina Marie Williams
Assessment Of Ruminal Fermentation Characteristics Of Condensed Tannin-Containing Forages Using Continuous Cultures, Christina Marie Williams
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Two independent studies were conducted to assess the effects of feeding condensed tannin (CT)-containing forages to continuous cultures to evaluate their impacts on ruminal fermentation and digestibility, with an emphasis on methane (CH4) and ammonia-N (NH3-N) production. In Chapter 3, treatments consisted of: 1) 100% alfalfa hay (AH), 2) 50% AH and 50% birdsfoot trefoil hay (dry matter (DM) basis; AHBFTH), and 3) 100% birdsfoot trefoil hay (BFTH). Three replicated runs lasted 8 d each, with the first 5 d allowed for microbial adaptation to the diets, and 3 d for data collection and sampling. Methane, neutral detergent fiber (NDF) …

The Economic Importance Of Draught Oxen On Small Farms In Namibia's Eastern Caprivi Region, Andrew B. Conroy, Mogos Yakob Teweldmehidin
The Economic Importance Of Draught Oxen On Small Farms In Namibia's Eastern Caprivi Region, Andrew B. Conroy, Mogos Yakob Teweldmehidin
Natural Resources & the Environment
The main aim of this study was to analyse and document the value of smallholder farmers’ use of Draught Animal Power (DAP) systems in the Eastern Caprivi Region and to test the economic viability of DAP usage versus using tractors. This study applied Rapid Rural Appraisal techniques (RRA), including a survey. Semi-structured interviews were conducted with 312 farmers at their farms and data was gathered on the use of and economics related to the draught animal power system. Crop enterprise budgets, project reports, expert opinions and group discussions were analysed. The research found that the use of animal power performs …
Effects Of Changes In Agriculture And Abundance Of Snow Geese On Carrying Capacity Of Sandhill Cranes During Spring, Aaron T. Pearse, Gary L. Krapu, David A. Brandt
Effects Of Changes In Agriculture And Abundance Of Snow Geese On Carrying Capacity Of Sandhill Cranes During Spring, Aaron T. Pearse, Gary L. Krapu, David A. Brandt
Proceedings of the North American Crane Workshop
The Central Platte River Valley (CPRV) in Nebraska is a key spring staging area for approximately 80% of the midcontinent population of sandhill cranes (Grus canadensis). Evidence that cranes currently are acquiring fat less efficiently than in the past along with a large increase in use of the CPRVby snow geese (Chen caerulescens) led us to evaluate waste-corn availability and index spatial and temporal variation in abundance of sandhill cranes and waterfowl using the CPRV. We also developed a predictive model to assess impact of changes in availability of corn under past, present, and potential future conditions. Predicted …
