Abstract

Twenty-four multiparous Holstein-Friesian dairy cows in mid lactation were used in a 4x4 Latin square changeover experiment with four 4-week periods to investigate the effect of altering the ratios of red clover (RC) and ryegrass silage (GS) in the forage component of their diet. Ratios (in the dry matter (DM)) were: R0, 0 RC:1 GS; R34, 0.34 RC:0.66 GS; R66, 0.66 RC:0.34 GS; R100, RC 1:0 GS. All cows received ad libitum access to their allocated forage with 4 kg of a standard concentrate per day. Results are presented in order of R0, R34, R66 and R100 respectively. Feed DM intakes (16.7, 17.8, 18.3, 19.0 kg d-1, s.e.d. 0.24, Plin
