The objects for which the Society is established are -
The Coopworth breed had its origins in the 1950's and 1960's in the crossing of the Romney ewe with the Border Leicester ram to produce the F1 Border-Romney and the subsequent inter-breeding of them to give F2 and F3 generation progeny, which were then eligible to be known and registered as Coopworths.
Since the 1970's the base of the Coopworth breed has been widened to include sheep bred from white faced breeds other than the Romney, by continued topcrossing with Coopworth rams.
Definition of a Coopworth
The present recommended breeding programme to produce a Coopworth, is two (2) topcrossings by Coopworth Single Entered (S.E.) rams over any other white faced wool breed or wool breed cross ewe. Alternatively registered or screened Coopworth ewes may be mated to any other white faced white wooled ram to produce F1 female stock that then must be mated to a Single Entry Coopworth sire to produce eligible foundation stock under sub section 3 following.
F2 Ewes and F3 Rams are acceptable for entry to Registered Flocks.
Eligibility for Registration
3:1 Composite Breed Flocks
The Society will recognise, inspect and separately accept under the title of Composite Breed Flocks, sheep falling outside Definition of a Coopworth, Section II.
Flocks applying for entry to the Composite Breed Flocks section must have applied Coopworth Society regulations specifically 4 to 11 following, for a minimum period of 3 years
To retain registration as a composite breed flock, subsequent generations must be maintained:
Deregistration of Ewes
In order to improve early conception, lambing percentage, lamb growth rate and wool weight and quality, the following sheep shall be deregistered, their ear tags removed and positive identification applied.
Inclusive of the above, the culling at the hogget stage and after the two tooth lambing shall be such that 40% of that age group must be culled between weaning as ewe lambs and mating as four tooths.
Flock owners are required to submit to the Council for approval and registration, a prefix for their flock. The Registered prefix shall be reserved for the use of the flock owner and shall be used for all sheep born in his flock. The purchaser of a registered flock shall have no right to the previous owners prefix or flock number without his written consent and the approval of the Council.
Deregistration of Flock
The Council reserves the right to inspect any flock and the records kept, and a whole flock can be deregistered if in the opinion of the Council, on the advice of any three inspectors, the standard of the flock, recording, or any acts prejudicial to the breed, make the flock unacceptable to the Council, or if the rules and regulations of the Society are not being carried out both in spirit or in letter.
Every year a number of flocks will be balloted by Council and subjected to an inspection of records and/or sheep. The owner of flocks not meeting Society requirements, may receive assistance and guidance from Council. If Society requirements are not met the flock may be deregistered at any time.
Eligibility for Single Entry Rams
AH rams and ram lambs mated in Registered Flocks must be Single Entered. To qualify for Single Entry a Ram must:
Society Standard REVs:
SIL Dual Purpose Overall (* DPO) = SIL Dual Purpose Growth (with Meat) + SIL Dual Purpose Meat (with Growth) + SIL Dual Purpose Reproduction + SIL Dual Purpose Survival + SIL Dual Purpose Wool SIL Dual Purpose Growth (with Meat) (* DPGM) = 36 * WWTBV + 106 * CVJBV - 10 * EWTBVV SIL Dual Purpose Meat (with Growth) (* DPMG) = 1 58 * LLANBV - 132 * FATBV SIL Dual Purpose Reproduction (* DPR) = 1720 * NLBBV SIL Dual Purpose Survival (* DPS) = 3400 * SURBV SIL Dual Purpose Wool (* DPW) = 126 * FW 12BV + 378 * LFWBV + 350 * EFWBV
|CW13V = carcass weight BV; EFWBV = ewe fleece weight BV; EWTBV = ewe live weight BV; FATBV = fat weight BV; FW12BV = fleece weight 12 BV; LEANBV = lean weight BV; LFWBV = lamb fleece weight BV; LWBBV = live weight 8 BV; NLBBV = number of lambs born BV; SUR|
N.B. When presenting Rams for Single Entry registrations, the most recent fertility record of the Dam must be included in the assessment of fertility. Dots over fertility records indicate that one or more of the lambs born in a particular year was not reared to weaning. Should the ewe have died or been removed from the flock that fact must be indicated by an X.
Certificate of Service
The owner of any ewes mated with registered rams not his own, must return to the Secretary, the Society's Certificate of Service signed by the owner of the rams.
A Flock Book shall be published annually giving a list of all flock owners and all rams Single Entered. For every flock a history will be given, also listed will be the number of ewes mated, number of ewe and ram lambs weaned the previous season, the prefix and eartag numbers of Single Entered sires used.
