This farm runs the Coopworth breed, a dual-purpose interbred based on the Border Leicester-Romney cross, popular in the 1960's for its ability to outperform both parents for lambing by some 20-30%, as well as maintain and improve on wool production and general mobility.
The breed society was established formally in 1970, pioneering the implementation of regulations forcing the selection of only the best performers as stud sires and recorded ewe flock replacements, and a set of performance based rules determining which individuals could remain in the flock.
The breed's philosophical home is Lincoln University, where renowned animal researchers Prof IE Coop and VR Clark, assisted by local Canterbury foundation breeder, Sir William Dunlop, promoted a performance based Flock Book, the first in NZ. http://coopworth.org.nz/
Progressive review and raising of performance qualifications by the Society has ensured the initial objective of capturing the hybrid vigour capabilities inherent in the cross, has not only been attained, but systematically and significantly improved on, in what is now a breed well in its own right several times removed in filial generation.
Waione Registered Coopworth Flock 32 - SIL 1207
Major Objective - a productive robust resilient dual purpose flock
The Waione flock has been interbred since the mid 1960's, when ewes screened for twinning and wool mated to Lincoln (Fl.1) and Hinenui (Fl.5) sires, formed the basis of the ram-breeding nucleus registered in 1970.
