The following email may not be suitable for all audiences. It contains words
like 'primitive', 'improved', and 'pure-Jacob'.
The term "Jacob(American)" was adopted by the ALBC just a few years ago
(1996?) to distinguish the divergence of the improved Jacob of England and
the Jacob in North America. The Jacob (American), in my opinion, (a) is a
landrace breed and (b) represents a small 'mixed' population of Jacobs that
(i) moved before c.1970 and were perhaps closer to Park Sheep ("unimproved")
and (ii) those that moved after c1970 influenced by the strategy of
conservation through commercialization ("improved").
My Jacob (American) landrace opinion is based on documents,articles and
pictures from three periods which I think are significant.
(1) The establishment of the Park Sheep Society by Elwes and Ewart in 1911
..."landowners keep in their parks various breeds which are not generally
known to those who keep sheep for profit only...more or less carefully
attended by their owners...values as much for their ornamental qualities as
for the wool and mutton they produce...a most important feature is their
ability to live like deer on grass alone without the daily attention of a
shepherd....they have no standard or pedigree...they are liable to degenerate
by careless crossing...and until a Society for the improvement of Park Sheep
is formed,such breeds as those we advocate must remain in their neglected
condition...the pied sheep..." Photos from the early 1900s and in particular
a group of photos from 1934 in Tabley Park are probably pretty good evidence
of the "original" Park Sheep types...forward horns, fused horns, slipped eye
patches. Yes, it's all there.
(2) The Jacob Sheep Society begins in 1969 to conserve the breed by promoting
its 'utility', showing and commercialization of its product. An article in
Oryx published by the Fauna Preservation Society (12/70)..."..if the Society
succeeds with two of its main three objects, namely the improvement of the
wool and the drawing up of a breed standard for show exhibitors, there will
inevitably be a loss of genetic material and the Jacob will no longer be a
primitive breed....It would be interesting to maintain some stock of
unimproved Jacob in parrallel with 'improved' stock in order to maintain the
widest range of genetic variablity possible, but also, by using the control
stock, to trace changes in the breed brought about by artificial selection."
It is my sense of the geography and events that Jacobs imported to North
America prior to 1970 had far less, if any, "improvement". However, on the
other side of 1970 it is not as clear.
(3) From Todd Hescock's writing (1977) "there are about 10,000 Jacob sheep in
Britain and most are in small hobby flocks although some were pet flocks of
larger commercial producers.They were considered a novelty breed but..I soon
concluded, it was a breed with a great commercial potential. The Jacobs were
emerging from the reputation as an ornamental breed at the time and with the
competitiveness of the shows and sales, the breed was starting to improve in
conformation and wool...It was possible to locate some quality animals...at a
reasonable price."
At this time the Jacob was under the aegis of the Rare Breeds Survival
Trust...and the ARK of 4/15/77 describes "...a breed can only survive if it
adapts to requirements...and all breeds can stand to be improved. To back
this up- I have crossed a Dorset Horn ram onto six poor quality ewes,
selected the best ram back to the ewe lambs and from these have a ram and ewe
lamb that are identical to pure Jacobs...I now intend to use this ram to
up-grade the rest of my "pure" Jacobs..." (Roger Mason). This is not the
only account; there are many others that continue into the 1980s.
Which might then raise the question of what flocks were improved. There is a
field review of the breed that occurs in the 1980s (I can't find the exact
date) that suggests that the Jacobs in Scotland and Ireland are not as well
'developed' as those in England. Did improvements move more slowly in
Scotland and Ireland? In the mid 1980s there is already considerable
emphasis on Jacob carcasses and wool and at this time the Jacob is dropped
from the RBST rare breed listing.
Martin Dally (Hopland Research and UC-Davis) was recently in England and
gave me the recent JSS brochure...top of the list for raising Jacobs has
changed from wool emphasized in the early 1990s (British Wool Bd. 'Select')
to "meat"....tender and lean, pasture fed, sweet as a hazelnut.
A definition of breed that is often used is "a group of animals that has been
selected by man to possess a uniform appearance that is inheritable and
distinguishes it from other groups of animals within the same species. It is
a product of artificial choice of characters that are not necessarily
strategies for survival but are favored by man for economic, aesthetic, or
ritual reasons, or because they increase the social status of the owner of
the animals." (Clutton-Brock, J. Domesticated Animals From Early Times,
1981)...and/or...a breed is a group of animals selected to have a uniform
appearance that distinguishes them from other groups of animals; when mated
together, members of a breed consistently reproduce the same type.
Breeds develop...from feral (wild)...to domestic landrace...to standard
breeds (uniformity and predictability). So why a Jacob (American) landrace
breed?
Landrace breeds are local flocks that are consistent enough to be considered
breeds but are more variable in appearance than standardized breeds...unique
due to founder genes (limited imports), geographical isolation (England/North
America), type (wool/meat), etc. Thus, I conclude that the Jacob (American),
without regard to 1950s or 1970s imports, is a breed, more specifically a
landrace breed.
