Current Projects

  • Evaluate  drought tolerant forage species for the summer months.  Relying on pasture to satisfy the nutritional needs of livestock throughout a growing season is risky.  Environmental extremes can create deficits in forage supply and drive producers to rely on conserved feed or costly supplements.  The most common environmental “extreme” is drought.  To reduce risk of having a forage deficit, producers can diversify their systems with warm-season annual forages.  Teff (Erogrostis tef (Zucc.)), is a new, drought tolerant, warm-season crop to the Southeatern US that can help diversify grazing systems.  Additionally, Teff hay is sought after by horse owners because of its high quality and has the potential to provide a substantial source of income to the producer.  The research proposed will focus on buffering the ability of Teff used with mixed-cool season pasture to meet nutritional needs of grazing cattle and produce hay for retail sale.

  • Biological control of invasive species. The proliferation of non-native invasive species is a problem throughout the southeast. Reclaimed mined-lands have been successfully used for forage production in the Appalachian region.  However, the encroachment of undesirable invasive plant species reduces the utilization of these pasturelands by cattle and conventional control methods are not  environmentally safe and cost-effective. The ongoing project will further explore the postnatal feed  and anthelmintic values of tannin containing invasive species. Control of gastrointestinal parasites (GIP) in the past 50 years has relied exclusively on the use of anthelmintic drugs, or de-wormers.  However, parasite resistance to these drugs is increasing rapidly in small ruminant parasites.  A number of studies have shown that ingestion of forages containing moderate levels of CT results in reduced levels of GIP.

Current Extension Programs

  • Grazing goats on high-investment pasture is not economical. Instead, goats can be grazed with cattle to control unwanted brush and weeds. Goats will consume trouble-some plants such as multiflora rose, thistles, blackberry, stinging nettle, and many more that cattle will not, while increasing the vegetative cover by favorable grasses and legumes. Using goats as biological control agents will decrease the need for costly mechanical cutting and herbicide application. Since we established the experiment 3 years ago, we have used the project for various extension activities (field days, demonstration, etc.)

  • In search of a "good" grass. Description: Early spring, mid summer, and late fall are periods in Virginia where there is frequently low forage productivity. A forage crop that could stretch the grazing season by providing additional high quality feed in early spring, mid summer, and late fall when the productivity of typical cool-season forages is low would provide livestock producers with lower feed costs and increased animal performance. The summer period specially is where feed shortage is observed the most. Teff (Erogrostis tef (Zucc.) is a warm-season annual grass adapted to various climatic conditions. Where commonly grown, Teff can be used for both human consumption and as animal feed. Teff is a relatively new crop in the US. Therefore, limited information is available on cultural practices such as seeding rates, fertilization and planting dates. The outcome of the 2006 trials showed that Teff can be an excellent emergency crop for the summer where it established rapidly and produced excellent yield with in 4-6 weeks. Currently, I am working with over  10 extension agents in Virginia as well as neighboring states to provide educational programs related to the production and maintenance of Teff.
