Current Projects

  • Novel Tall Fescue Variety Trial
    Tall fescue variety ‘Kentucky 31’ remains the base of forage systems in the transition zone of the southeastern United States. Although KY-31’s association with ergot alkaloid benefits the plant persistence and resistance to pests, it can cause fescue toxicity in livestock that eat the forage. The forage program has recently started a novel tall fescue variety trial to identify cultivars that can be competitive with the yield, nutritive value, and persistence of KY-31 tall fescue in Southside Virginia. These novel varieties contain a strain of endophyte that are still beneficial to the plant and do not negatively affect the animal. 

  • Cover Crop Mixture Study
    In Southside Virginia, it is common for commodity crop growers to also maintain a livestock herd. With a growing interest to pursue a year-round grazing system, an option available to these producers is grazing cover crops. The forage program has recently started to evaluate to production potential of different cool-season annual forage systems. These forage systems include mixtures of different grasses and legumes. The species included in this study include: wheat, rye, barley, oats, annual ryegrass, crimson clover, Austrian winter pea, and hairy vetch. 

  • Horse Farm Conservation Practices
    Resource conservation on horse farms has lagged behind other agricultural commodities. A previous study at the University of Kentucky showed that proven resource conservation techniques are applicable to equine operations. The transferability of these conservation practices will be established on five horse farms in Virginia and will be monitored for economic and ecological improvements.

The goal of the forage extension program is to provide unbiased information through applied research that relays applicable management strategies to support our forage and livestock producers; leading to an improvement of their production efficiency, increase the profitability of their operation, and enhancing forage, livestock, and environmental quality. By working with extension colleagues, local extension personnel, and producers, we can provide educational programs and written publications on relevant and emerging topics of forage and livestock production in Virginia.
