Exploring Primitive Breeds
In late 2018, the Cumbria Support Group of the Rare Breeds Survival Trust1 (RBST) launched their Primitive Produce Project. Two newly weaned wethers (castrated males) from each of the seven British primitive breeds, also known as Northern European or North Atlantic short-tailed sheep, were gathered and raised under identical conditions. The fleece and meat of each would then be compared, having removed influential variable factors such as feed, housing and weather.
The seven British primitive breeds are Boreray, Castlemilk Moorit, Hebridean, Manx Loaghtan, North Ronaldsay, Shetland and Soay. All but Castlemilk Moorit originate from small and/or remote islands and remain ‘unimproved’ by the introduction of more commercial breeds, as has happened to many mainland breeds. All are small coloured sheep, many with additional kemp and guard hairs in their fleece. On the RBST’s 2019-20 Watchlist, Boreray and North Ronaldsay are ‘Vulnerable’ and Castlemilk Moorit, Manx Loaghtan and Soay are ‘At risk’, with Manx Loaghtan numbers steadily declining.
The wethers were reared on grass and overwintered on a farm near Coniston, in the Lake District National Park, alongside hill breeds such as Cheviot and Herdwick. These primitive breeds are too small to kill as lamb meat, so were brought on until November 2019 to give hogget meat, with the added advantage that the first clip fleeces could be collected. With a longer growing time, the locks are longer than from more mature sheep and as lambswool are generally of better quality. Apart from dipping 6-7 months before clipping, no chemicals were used on or required for these sheep.
All were sheared with electric clippers in April 2019, apart from the Soay that naturally lost its fleece. The fleeces were skirted and staples collected from the base of neck and shoulders for each breed. These were soaked in rainwater overnight then briefly washed in hot water with soap, rinsed, spun at low speed (400rpm) and air dried. Weight loss during washing varied from 21% (Shetland) to 45% (Castlemilk Moorit), suggesting relatively low dirt and lanolin in several. 100g samples were passed to Judith for processing.
Fibre preparation is the key to spinning! The clean fleeces were picked through to remove vegetable matter and second cuts.2 Initially the North Ronaldsay was drum carded for speed, but as it was partially cotted3 on the skin side and contained second cuts, even with only two passes through the drum carder, nepps4 formed. These were probably from the second cuts and the coarse (72 point) drum carder. For this reason only two other fleeces, Boreray and Hebridean, were drum carded, again with two passes. The double-coated Boreray, with coarse hairy outer and fine inner layers, had a 10-15cm staple. Combing might have removed most of the hair, but with just 100g of fibre, blending was more appropriate. The Hebridean’s 5-15cm staple, poor lock structure and some second cuts would also have made combing very wasteful. However, both fleeces carded and spun up well.
Three of the fleeces were carded on mini hand carders (112 point), as the drum carder would have created a lot of nepps. The Castlemilk Moorit and Manx Loaghtan had a staple length of 10cm, while the Soay was only 4cm. All were very fine. Mini carders were more comfortable than standard ones, although smaller rolags result.
The Shetland had a surprisingly long staple of 18 to 25cm but no hair, i.e. it was not double-coated. Flick carding the tip and butt of each lock, then hand carding, produced nepps, so it was combed on two-row small wool combs with three passes. The fibres were dizzed5 off into tops with aligned fibres. Over 50% of this fleece was wasted, whereas the carded fleeces lost around 20% of their weight during preparation and spinning.
The fleeces were spun on a Schacht Sidekick wheel at a ratio of 9:1, then plied at 10:1, except for the Soay which was spun and plied on a Haldane Shetland at 8:1. After plying, the yarns were soaked in warm water, spin-dried and air dried with no weight attached. As intended, all were a DK weight.
The three drum-carded fleeces were all spun from the length of the batt, short forward draw in a semi-worsted style. The North Ronaldsay was fine and wanted to be spun thin so it was three-plied, making a slightly heavier yarn. The Hebridean was an easy spin, the variable staple length and second cuts resulting in a rather uneven two-ply yarn. All the hair in the Boreray made for a quick, easy spin, two-plied. The combed Shetland was spun from the butt end of the locks with a short forward draw to produce a true worsted yarn. It was very fine, so was three-plied. Despite the worsted method, the fibre’s natural crimp kept the yarn fluffy.
The Castlemilk Moorit and Manx Loaghtan were spun English longdraw; this was quick and such fun. They were two-plied and produced a typically airy woollen yarn. It was interesting to see how even the final yarn colour was – the carding and woollen spinning distributed the sun-bleached tips randomly throughout the fibre.
The Soay had a lot of nepps, probably because its fragile sun-bleached tips broke off in the carding. A smooth draw was therefore difficult so a supported longdraw was used, where nepps could be removed during spinning. The result was a fairly airy but rather lumpy two-plied yarn.
The range of colours and processing and spinning methods demonstrated the variety of fleeces from the seven breeds, making for a most interesting project. All produced a very useable yarn, except perhaps for the hairy Boreray. The most traditional processing methods were time-consuming but produced the best fibre to spin.
Spinning a good rolag with English longdraw (Manx Loaghtan and Castlemilk Moorit) was fast and produced a lovely woollen yarn. The Manx Loaghtan was slightly better, probably because of the greater crimp. Spinning a true worsted yarn from a roving (Shetland) was also a delight and gave a beautiful soft and surprisingly fluffy worsted yarn. Because of the waste with the Shetland, the overall ‘best’ yarn was the Manx Loaghtan.
Samples were woven on a vintage Weave-it pin loom in plain weave, fulled lightly by hand in warm water and dried flat. DK weight yarn on these looms gives an open weave, but all the samples fulled well to close up the weave. As expected, the woollen-spun samples shrank more than the worsted-spun samples. All the yarns would work as weft; there was insufficient to try a warp but possibly only the true worsted Shetland yarn would be suitable.
Square samples were knitted in stocking stitch with a moss stitch border, matching the fulled woven samples for size. The size of needles and number of stitches needed did not vary much; typically, samples were knitted on 3mm needles, with
25 stitches and 32 rows.
In November 2019, RBST held an event promoting the seven breeds in the study. Sheep breeders, breed societies, chefs and restaurateurs were invited and presentations and demonstrations given on the rearing, butchery and this fleece comparison. It was noted that prices paid by craft workers for fleeces from these breeds at events such as Woolfest6 far exceed those paid by British Wool7 and so increase the potential value of the fleece. Information boards were produced and displayed for each breed containing samples of the locks, spun yarn, knitted and woven samples.
The event concluded with a ‘blind’ meat tasting of all seven breeds and each invitee described each meat. Word clouds have since been created to compare the meats. Most importantly, an assessment of the financial viability of these breeds was given, showing that not only can primitive breeds be profitable, but that demand for the coloured fleece is a noticeable contribution to this.
