Oat and wheat added to annual ryegrass pasture to improve the seasonal forage offer

摘要

Grazing of annual ryegrass ( Lolium multiflorum L) pasture is extensively used on livestock farms of Argentina ( Jacobo et al,2000) providing high quality forage during winter and early spring.Nevertheless, in the subhumid region of the country, forage shortage begins during fall and early winter annual crops such as oat can be more adequate (Brizuela et al, 2001).Complementary use of winter annual crops with different seasonality is proposed in mixtures to elongate the grazing period during the cold season (Juskiw et al, 2000).
