Booroola Merino
The Booroola Merino is a Merino strain linked to the Booroola property in New South Wales and to the FecB mutation, which can raise ovulation rate and litter size. It remains a wool sheep within a Merino context, but the name usually appears when prolificacy genetics are part of the breeding plan. That makes Booroola different from a simple place or fleece label; reproductive performance is central to how the strain is used.
Adding Booroola genetics requires more planning than choosing a prolific ram. Extra lambs increase demands on ewe nutrition, lambing supervision, shelter, udder soundness, and decisions about rearing twins or triplets. Commercial use should match the genetics to feed supply and labor, while seedstock records should state whether animals are tested carriers or assumed carriers. Wool quality, fertility, lamb survival, and ewe welfare all have to be selected together.
