Local Merino, 1/4 local Merino and 1/2 local Merino ewes were grazed on oversown and top-dressed tussock grassland. When ranked for lamb and wool productivity at 2 and 3 years of age both the Booroola crosses were superior to the Merino. Satisfactory lamb weights and ewe fleece weights were obtained at lambing percentages above those normally obtained on this class of land.
