ABSTRACT. - Context. For extensive production systems, crossbreeding may be a tool that can be used to achieve production of quality wool and meat to suit market specifications. Aims. To evaluate two levels of crossbreeding of Dohne Merino (DM) sires with Corriedale (C) ewes on productive and reproductive traits of the crossbreed progeny in comparison with purebred C progeny. Methods. Two studies using three genotypes ? 100% C (100C), 50% DM × 50% C (50DM) and 75% DM × 25% C (75DM) ? were carried out. In Study 1, growth, wool production and nematode resistance were evaluated (n = 1652). In wethers, carcass weight, subcutaneous tissue thickness, weight of high value cuts, meat shear force and fresh meat colour were also evaluated. Before first mating, the presence and number of corpus luteum was recorded to evaluate puberty and ovulation rate, respectively, in 380 18-month-old hoggets. In Study 2, fertility, prolificacy and lambing percentages were measured in 382 ewes.
Aims: To evaluate two levels of crossbreeding of Dohne Merino (DM) sires with Corriedale (C) ewes on productive and reproductive traits of the crossbreed progeny in comparison with purebred C progeny.
