To; All Invited Members of Teleconference
8th. May 1993.
Regrettably, I will be away from home and
unable to take part in this conference, which may well be an historic event
and a turning point in the fortunes of the Belted Galloway Breed.
Since this will largely be concerned with
introductions I hope that the following will serve in my absence.
I
am principally concerned with the conservation of the genetic endowment
of the 'original' Beltie and operate within a closed nucleus founded on
six foundation dams (two lines since discarded) and one bull line. The
mature weight of the retained females is above 560Kgs (1230 lbs.). The
seventeen and fifteen yr. old, weighed on the 27th. of this month were
510 & 520 at their mid lactation (end of winter weighing). That bull's
lowest weighing, when standing at AI was 1020 Kga. Some of the US members
have walked the herd and have handled the present stock bull who is his
son. He weighed 940Kgs (2070 lbs) on the 27th (160 Kgs less than his full
condition weight). So my idea of 'original' is on the heavy side of
average.
Conservation of genetic endowment in a small
(40 females/4 lines) nucleus cannot conserve the genetic variation of the
breed. It is simply a snapshot at one particular moment of time from one
specific viewpoint. It is simply a reference point, not unlike the original
Hereford Angus controls used in the Germ Plasm evaluation Program at Clay
centre in the US, without the variation inherent in the vastly larger sample
numbers. Determining more than one reference point, is crucial.
I can only provide one reference point, one specific set of genetic endowment
interacting with one particular environment. We could charge into increasing
the numbers on the ground and get it disastrously wrong !
Conservation by MOET? In my initial
program I collected 70 embryo. 56 are gene banked. All the original dam
lines, bred back one generation to Firth King Henry and some semen from
his son Burnside David (my original foundation bull).
To round off the 'hands on' experience Dr.
Butson agreed to take four embryos into Canada and now has three calves
on the ground and one to come. Mr. Chatfield has three and Mr. Randy Hadden
in Georgia has two. They all came from a single flush from one donor (Netherwood
Nan). Simply in number terms this donor, now six and a half and nursing
her fourth natural calf, has already contributed 7 additions to the breed,
banked 2, and probably another four in utero. Her fifteen year old dam
is currently nursing her thirteenth calf and looks good for a few years
yet. But, even if I never flush her again, she has already exceeded her
dam's lifetime production.
Conservation by IVM/F (Invitro Maturation
& Fertilisation). During the program the team assisting in the work
(Edinburgh Genetics, Dr J. Mylne) salvaged ovarian tissue, post mortem,
from a seventeen year old, put down because of aged arthritis. From this
tissue we recovered 32 oocytes, matured and fertilised 28, all of which
graded as embryos but I elected (mistakenly) to limit the storage to 11
of the grade 1. With fourteen natural calves behind her, the extra eleven
embryos was a considerable bonus.
Although I did it from a conservation aspect
it has enormous potential to increase numbers. Much has still to
be learned of breed specific problems, optimal donor and recipient criteria,
etc. It still has significant cost penalties when used locally: somewhat
less when used as a means of genetic exchange internationally. But improved
demand for Belties would shift the balance and improved techniques will
also bring costs down eventually. It is worth encouraging.
I consider an Embryo and Semen Register,
in some form, essential. I grossly over-recorded my embryos for my
conservation records. ... A much simpler record would be perfectly adequate
for all other purposes. Here the IETS might be the best advisors.
Our common ground is to prevent the Belted
Galloway from disappearing from the World's cattle population, even though
our methods differ considerably. I am totally opposed to the introduction
of alien genetics without the filter of a full five generation grading
up register. I have the greatest respect for the finely tuned judgement
of practical breeders who depend on cattle for their livelihood. The
Herefords have hit the right button with their Baldy Beef initiative. We
have an equally prepotent marker to stamp on Fl crossbreds and exploit
in the same way. And retrieve from that crossbred pool the new damline
contributions from a few outstanding females being bred back to a Beltie
for another four generations. We shouldn't sacrifice the existing Beltie
dams to produce the slaughter generations: we need to hold on to them where
they are and breed them pure ! !
I might as well take this opportunity to set
my stall out.
I am not persuaded that EPD, BLUP or other
methods of objective measurements, on their own and commonly used in breeds
with large numbers, is appropriate for Belties at this time. We obviously,
and urgently, need some easily measured traits of high heritability and
commercial significance. Some "index of merit" of the Beltie's other importance
characteristics bolted on to EPD might serve us better initially. Too many
variables slows progress considerably. But relying on too few can be a
disaster.
Some of the suggested EPDs without their related
parameters would be meaningless to me. E.g., Height. Would a two year old
bull 52 inches in height who was showing more than 16" of daylight under
his ribs meet the criteria of chest depth? Or if he was 36" from shoulder
to pins, 12" pins to pelvis and 24" shoulder to poll would these be appropriate
length relationships for a Beltie? And weight? 1500 lbs in weight and at
least 80" in girth. Knowing his EPD based on height and weight doesn't
mean a lot without the others.
Testes mass without knowing the scrotal attachment
poses a similar problem. The correlation between mass and fertility is
soundly based. But the last thing anyone needs in a stock bull is testicles
dangling like balls on a piece of string, knocking against his hocks. They
need to be in a thick skinned scrotum with a broad firm attachment.
As far as characteristics are concerned,
the following are what I think a typical Beltie should have. Not necessarily
what they should be, or what breed standards say.
Polling characteristics? Belties are polled.
Full stop.
Belties are Black or Dun if they are homozygous,
carrying the Galloway dilution recessive. Anything else is a belted variant
of another breed.
A full belt. Nice to see it about 14" wide
across the back and not too wide on the underside but not critical. Other
mismarks? Personally I wouldn't sacrifice an excellent or above average
pureblood female from the breeding pool for a minor mismark. Simply move
her out into the third or fourth generation of a grading up register, and
use a bull excelling in marking on her. Slightly different with a bull.
A slightly mismarked bull with a high 'commercial' EPD isn't going to harm
the breed's reputation out working in a commercial beef herd. (That demand
should almost be an automatic bonus if we get the pure blood criteria right).
What do the Herefords do, nowadays, with a bull slightly mismarked about
the head?
The only baircoat a Beltie should have is
a survival coat. One that sheds rapidly in the spring upwards and forward
from the hindquarters; and takes any buildup of lice nits with it before
they hatch. The replacement summer coat should be short, shiny and smooth:
it later thickens to form the winter undercoat. The undercoat should start
to grease up in the autumn when the guard hairs start to show and lengthen:
the function of the guard hairs is simply to gather rain and melting snow
and channel it down the body quickly
I
haven't seen or heard of any of those mentioned in Belties. I do a lot
of sib test mating in my nucleus; son to mother, sire to daughter, full
brother sister. So far I haven't turned up any serious deleterious recessives.
I test annually for TB, Brucella, EBL, IBR,
Lepto Hardjo, BVD, an IPX for hidden virus and every three years for Johnes.
But it has no commercial value whatsoever. Disease priority will vary from
country to country and herd to herd. Belties are relatively disease (and
parasite) resistant. Disease susceptible animals are probably culled, anyway,
for other reasons.
Occasionally I have an animal with sunstroke.
Never fatal and usually in a wide belted animal.
I select positively for dam longevity (the
associated traits fall into place almost automatically -- feet, thrift,
milk, survival coat, head protection, udder attachment, teat placement,
mothering ability etc.). I discriminate punitively against poor teat placement
or loose udder attachment.
Bulls are selected on the basis of their performance
within their yearling peer group. Any male that isn't steered gets the
chance to be a bull. (Usually four or five.) A bull that fights his way
to the top of the heap gets the rosette. Invariably that means he's the
heaviest, develops the best bone & muscle structure, has the right
kind of head and feet and is cocksure and masculine. The top two are mated
to four of the worst heifers (two each) and the rest are fattened and killed
as young bull beef (21 months and around 560 Kgs).
I select very positively for placid temperament
in both sexes, simply because fighting with an ill-natured beast is now
beyond me.
There is a broad measure of support within
the UK for this kind of initiative. Inevitably it must be US led, because
of the numbers, and that will mean compromise and give and take from all
sides. Smaller societies will want to retain their autonomy within a framework
of co-operation rather than compliance.
I hope there is something on the stall that
may be of value. This initiative is exciting and has great promise. But
it's a big league we're entering. This isn't the ornamental market. Someone
has to be the devil's advocate and spell out just exactly what we're up
against.
I am online to host computer networks in the
US and Europe and can act as an Email postbox in the UK. The conference
forums and bulletin boards are not connected with Belties but there is
no reason why an attempt couldn't be made to set one up. One significant
advantage (in addition to instantaneous transmission of files) is that
a log of the proceedings is automatically kept and down loaded at the end
of a session. I'm normally on to the US on CompuServe CB simulator (Handle
'Wooden Spoon') for an hour most Sundays from 11 pm GMT. Mostly trivial
chat but no reason why it shouldn't be serious. It's relatively inexpensive.
... If any member is online it might be helpful to establish a communication
link to start with. The user software is simplicity itself. No special
computer knowledge is needed.
Kind Regards to all. I hope we can make it
a success.
