Forage Conservation Techniques: Silage and Haylage Production

By: J.J. Romero, Miguel Castillo, J.C. Burns

This publication provides information on two forage conservation techniques to help producers select a technique that maximizes nutrient conservation efficiency and minimizes production costs.

Warm-Season Perennial Forages Conserved as Hay: Nutritive Value and Quality

By: J.C. Burns, D.S. Fisher, E.S. Leonard

This bulletin brings together 18 independent experiments that address aspects of nutritive value and quality of perennial warm-season forages preserved as hay.

Supplementation of Native, Perennial Warm-Season Grass Hays and Annual Corn Silages and Preference Among Silages of Annual Grasses: Dry Matter Intake and Digestibility

By: J.C. Burns, D.S. Fisher, E.S. Leonard

The dry matter yield and nutritive value of perennial warm-season grasses and corn silages were evaluated for preference and nutritive value when cut a different maturities and supplemented with crude protein and energy.

Forage Quality: Concepts and Practices

By: J.J. Romero, Miguel Castillo, J.C. Burns, Shannon Davidson, Philipe Moriel

In this publication, we describe the factors that affect forage quality and discuss prediction indices that can be used to assign a science-based measure of quality to forages.

Grazing Behavior of Steers Offered Different Warm-season Grass Canopies: Nutritive Value and Particle-size Characteristics of the Diets

By: J.C. Burns, D.S. Fisher, E.S. Leonard

The dry matter yield and nutritive value of flaccidgrass, with potential as a ruminant feed as well as for biomass stock and adapted to the Mid-Atlantic Region, was evaluated for its response to a range of nitrogen rates when cut at three maturities.

Potential in the Upper South for Interseeding a Legume into Upland Switchgrass: Yield and Nutritive Value

By: J.C. Burns, D.S. Fisher, E.S. Leonard

Switchgrass (Panicum virgatum L.), a long-term perennial, warm-season grass, declines in nutritive value with advancing maturity and increased yield potential. This experiment evaluated the potential of interseeding either perennial legumes or an annual legume into an established stand of upland switchgrass to improve nutritive value while attaining desirable dry matter yields.

Ruminant Preference for Bermudagrass Hay With and Without Exposure to Swine Lagoon Effluent

By: J.C. Burns, D.S. Fisher, E.S. Leonard

Bermudagrass hays cut from a swine lagoon spray field prior to and following effluent application and hays cut from a non-waste bermudagrass field were evaluated for preference based on short-term dry matter intake by cattle, sheep, and goats.

Evaluation of a Cow-Calf Grazing System in the Piedmont: Animal Performance and Pasture Productivity

By: J.C. Burns, D.S. Fisher

In the North-South transition zone both cool-season and warm-season, perennial grasses can be grown and have potential to be used sequentially in a cow-calf production system. This five-year experiment evaluates tall fescue and bermudagrass, grown in separate stands but grazed in sequence, as a pasture system for the Piedmont. The study evaluates two levels of nitrogen fertilization and variable stocking versus a range of fixed stocked treatments.

Silages of Native Switchgrass and Gamagrass: Fermentation Characteristics, Nutritive Value, and Quality

By: J.C. Burns, E.S. Leonard

This bulletin publishes the results of eight experiments that addressed aspects of nutritive value and quality of perennial warm-season forages preserved as hay, baleage, and silage.

Annual Grasses Preserved as Silage: Fermentation Characteristics, Nutritive Value, and Quality

By: J.C. Burns, E.S. Leonard

This bulletin brings together 13 independent experiments that address aspects of fermentation, nutritive value, and quality of cool-season and warm-season annual forages preserved as silage.

Nitrogen Fertilization of Switchgrass and Gamagrass: Dry Matter Yield and Nutritive Value

By: J.C. Burns, E.S. Leonard

This bulletin publishes the results of two experiments—one with switchgrass and one with gamagrass—that address responses of dry matter yield and nutritive value to nitrogen fertilization when the grasses are cut as hay.
