This bulletin brings together 18 independent experiments that address aspects of nutritive value and quality of perennial warm-season forages preserved as hay.
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.
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.
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.
The dry matter yield and nutritive value of the perennial warm-season grass, 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.
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.
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.
