Extract

Previous work has shown that supplementing grazing ewes with soyabean meal increased total intake but did not influence dietary selection or herbage intake when sward heights (SH) were 4-6 cm (Hyslop et al, 2003). This study’s main objective was to investigate body condition score (CS) as a possible factor influencing voluntary herbage intake and diet selection in 30 lactating Scottish-Blackface (SBF) ewes grazing different plots of mixed perennial ryegrass (PRG) and white clover (WC) swards.
