Winter cereals were evaluated for fall and spring forage production and nutritional value following seeding in late August, mid September, and early October of 2001 and 2002. Cultivars were two winter wheats, two winter barleys, and four winter triticales. Forage samples were clipped in November of each seeding year and the following April to represent availability as pasture. Herbage composition was evaluated in terms of crude protein, neutral detergent fiber (NDF), in vitro true dry matter digestibility, and NDF digestibility. Earlier seeding increased forage production, to a much greater extent during the following spring than by the end of the seeding-year growing season. Results indicate a role for fall-seeded winter cereals for extension of the pasture growing season, particularly in April.
