Abstract

The development of more productive sheep is possible through selection within breeds and crossbreeding or by importing new genetic material. The introduction of new breeds involves complex and time consuming development of import protocols, and health testing of source flocks and individuals prior to entry into NZ. Repeat health testing of sheep (and/or recipient ewes receiving embryos) and long scrapie surveillance protocols are required prior to release. Of the new breeds, the East Friesian with large body size, high fecundity and milk production, leanness and moderate wool production will likely prove the catalyst for a sheep milking industry, and will be a component of a productive meat and wool dam. Early data confirm that the East Friesian offers considerable opportunities in these areas.
