Abstract

Forage dry matter (DM) yield and its nutrient content are important in livestock nutrition; however, they have distinct, even opposite responses to mowing regimes. To optimize forage resources, two independent field experiments were conducted to determine effects of initial mowing time (15-day intervals from May 15 to September 1) and mowing frequency (one to five times per year) on DM yield and nutritive value of Leymus chinensis (Trin.) Tzvel. The greatest cumulative DM yield (cDMY), pre-mowing crude protein yield (pCPY) and cumulative crude protein yield (cCPY) were attained when initial mowing occurred from July 15 to August 15. The crude protein (CP) concentration of pDMY was higher, wh..
