“…The skins, 20 per breed, were from 5-month-old wether lambs of the Romney, Coopworth, and Perendale breeds, being the progeny of ewes run in a breed comparison study (Dalton & Ackerley 1974). The lambs were born between August and the end of September 1978, weaned and shorn on 1 December 1978, and weighed and slaughtered on 16 January 1979.…”

Skins from 5-month-old wether lambs reared under hill country conditions were processed and evaluated in terms of their impact on the New Zealand tanning industry. Breeds examined in this work were the Coopworth, Perendale, and Romney. The Perendale produced the most desirable wool characteristics for the production of leather tanned with the wool on. Although the Perendale showed the poorest grain leather qualities, the grain layer itself was stronger and more elastic than in the Romney and the Coopworth skins. It is suggested that increased selection of the Perendale for woolon leathers would mutually benefit fellmongers and tanners of all leathers derived from New Zealand lamb pelts.

Ten 1-year-old sheep of each of the breeds were pen-fed a pelleted diet of 60:40 maize: lucerne at 30, 40, 50, 60, or 70 g/kg initial live weight 0075 /day for 21 weeks divided into 3 equal periods. Intake, wool growth, and body growth were considered relative to body weighto' 75 to allow for the effect of between-breed differences in body size. Estimates of the conversion of dry matter (DM) intake/body weighto. 75 to body weight gain/body weight o . 75 did not differ between breeds or periods. On a pooled within-breed, within-period basis, wool growth/ body weight o . 75 (r = 0.69) and fibre diameter (r = 0.69) were correlated with DM intake/body weight 0075 • During the last 2 periods the sulphur content of the fleece wa:o correlated within breeds (r = 0.62) with DM intake/body weighto. 75 • Fibre diameter (r = 0.76) and sulphur content of the fleece (r = 0.62) were correlated with wool growth/body weight o · 75 • The regression coefficient for the regression of clean wool/body weight o . 75 on DM intake/body weighto. 75 did not differ between breeds but increased between periods as the seasonal wool growth maximum was approached. The intercepts were different between breeds and decreased between periods. The ranking of breeds for clean wool/ body weight o . 75 at an intake of 40 g DM/body weight o . 75 /day was Corriedale, Coopworth, Romney, and Perendale in the winter and spring and Coopworth, Corrieda1c, Romney, and Perendale in the early summer. The regression coefficients for the regression of both fibre diameter and sulphur content of the fleece on clean wool/body weighto. 75 did not differ between breeds or periods. The intercepts, which differed between breeds, did not differ between periods. 251

“…Dalton & Ackerley (1974) have described the design of the experiment and the establishment of Romney, Coopworth (Border Leicester X Romney ewes mated to Coopworth rams), and Perendale. The original ewes were obtained in 1968 from various flock~through the co-operation of Breed Associations where appropriate.…”

Greasy fleece weight, staple length, quality number, character, and severity of staple unsoundness and cotting were recorded from Romney, Coopworth, Perendale, Cheviot, and Dorset-Romney ewes over 7 years. All breeds were grazed together except during mating. Romney had the heaviest fleece weight followed by Coopworth, Perendale, Dorset-Romney and Cheviot. Fleece weights increased to 3 or 4 years of age and declined to 5 years of age, Coopworth and Perendale showing the greatest decline. All breeds except Romney showed a decline in fleece weight associated with fertility status, dry ewes having the heavie:,t fleeces. Romney ewes rearing their own single lamb had higher fleece weights than dry ewes. The subjectively assessed fleece characteristics were not influenced by fertility status. Romney and Coopworth had a higher proportion of cotted fleeces than the other breeds and Cheviot had the highest proportion of fleeces with staple unsoundness. Increased staple unsoundness was associated with lower fleece weights for all breeds, but only Romney and Coopworth showed a decline in fleece weight with increased cotting.119
