Fertility in Angus Cross Beef Cows Following 5d CO-Synch + CIDR or 7d CO-Synch + CIDR Estrus Synchronization and Timed Artificial Insemination
(Virginia Tech. Powell River Project, 2013)The present study determined whether a 5d CO-Synch + CIDR protocol with a two doses of prostaglandin F2α (PGF) would improve timed AI pregnancy rate compared to 7d CO-Synch + CIDR protocol in beef cows. Angus cross beef ... -
Fertilizer and Density Treatment Effects on Woody Bioenergy Production on Mined Lands: Year Five Report
(Virginia Tech. Powell River Project, 2013)Planting woody biomass for energy production can be used as a mine reclamation procedure to satisfy the SMCRA and provide renewable energy for the United States. This study examines the productivity of woody biomass on ... -
Fertilizer and Density Treatment Effects on Woody Bioenergy Production on Mined Lands: Year Six Report
(Virginia Tech. Powell River Project, 2014)Planting woody biomass for energy production is investigated as a mine reclamation procedure to satisfy the SMCRA as an ongoing study at the Powell River Project. Annual remeasurement and analysis of three experimental ... -
Forest Composition and Growth After 9 Years on a Virginia Mine Site
(Virginia Tech. Powell River Project, 2011)The eastern USA’s Appalachian region contains abundant coal resources and supports extensive deciduous forests. Appalachia’s forests provide ecosystem services, including carbon storage, watershed and water quality protection, ... -

Impact of Body Condition Change Post-Breeding on Reproductive Performance of Beef Cows
(Virginia Tech. Powell River Project, 2014)Body condition score (BCS) is a commonly used tool for evaluating the nutritional status of beef cows. Good nutritional status of beef cows is one of the essential components for improved reproductive performance. The ... -
Levels of Dissolved Solids Associated with Aquatic Life Effects in Headwater Streams of Virginia Central Appalachian Coalfield Region
(Virginia Tech. Powell River Project, 2011)Benthic macroinvertebrate communities in headwater streams influenced by Appalachian coal mining often differ from communities in minimally disturbed streams. Elevated levels of total dissolved solids (TDS) associated with ... -
