Heel low:

I just imagine you in OUER summer!
Hate heat...nope, not going thar.
I cannot work in heat, so no work = very unhappy me!
I pitched the ram barn out yesterday...because it was a cool day. Still lots of work but add heat and I want to crawl out of my skin and still work. Not good--bloody mess that would be!
You are combating uphill!
Do Dorpers has shown a year symptoms of jenetic problems due inbreeding in Canada?
I have had Dorpers since May 2016 and chose an unrelated ram and ewes produced by UNRELATED rams so the foundation of females was pretty unrelated, diverse contributors for a foundation flock. Now, I did bring home a daughter and mother, but daughter is by a ram that is not closely related to any other Dorpers here....HOWEVER...the South African genetics we have are loosely sprinkled and related in all Dorpers--can't be Dorper if there is no genetics FROM South Africa, eh.
So, likely because we cannot import directly from South Africa (country of origin) any more, we are allowed to UPGRADE the Dorper breed. By back crossing to registered Dorpers, these progeny are considered registerable as a domestic purebreds for females at 15/16's and males 31/32.
(k) GRADING UP – That CSBA implement a grading up program for the registration of sheep in Canada. The grading up of any breed of sheep will only be done from the ram side. (Only registered full blood or purebred rams can be used in the grading up program). The registration paper for graded up animals will always be indicated by colour or other designation. The 50%, 75%, 87.5% and 93.75% animals will be identified with flock letters tattooed in the right ear and a number and year letter tattooed in the left ear. Ewes are recorded at 50% or more and are considered as domestic purebred when they are 15/16 purebred (93.75%). Rams will only be recorded as domestic purebred if they are 31/32 pure or more. Both rams and ewes will be identified with flock letters tattooed in the right ear and a number and year letter tattooed in the left ear. The CSBA has the authority to refuse or rescind the registration of any purebred animal that does not reflect breed characteristics. Anyone doing breeding up must do at least one parentage test per breeder per 50 head at the breeder’s expense. The breeders involved must approve the upgrading program on a breed by breed basis. The implementation of this program is subject to further regulations as set by the board of directors.
Having only bred two ewes to a very unrelated ram (Boss Man), I have no idea if there are genetic problems in the Dorper breed due to inbreeding in Canada. I looked at the inbreeding coefficients and was satisfied my foundations and breedings with Boss Man would be pretty diverse.
I never chose Dorpers that were inbred.
Inbreeding Coefficients
Boss Man - 0.246%
Peanut - 6.655%
Èva - 1.121%
Èder - 1.121%
Snickers - 4.079%
D'Arcy - 3.366%
Èden - 2.629%
Duro's dam - 2.863%
The highest inbred Dorper is Peanut and I chose her because I wanted old time Dorper lines.
We know what Boss Man bred to Snickers and Peanut is (the three lambs from this June) and Boss Man bred to D'Arcy = 1.779% & bred to Duro's dam 4.197% so wild optimistic guess for Duro would be half her dam at 2.09%.
My lambs by Boss Man are 1.121% & 2.629% inbred...that's pretty low.
I done good...those numbers are lower than any in my foundation ewe flock...an improvement from my beginning point, yes???
I am now due to backcross or INBREED (linebreeding is a nicer, less extreme term!) my lines. Find a top representative relative (which is what Eldad is suppose to be!) and use him to instill same to same or better. We are breeding for a consistent product that conforms to a Breed Standard. You keep doing wild outcrosses of completely unrelateds and I may as well be breeding rhinos for release into the wilds...yes?
Hybrid vigour is fine...to a point but I don't want to rely on unrelateds or unlikes bred to differents as the only reason why my animals are doing well! I want to breed good animals to good animals with the desired traits I want to conform to the Dorper Breed Standard...that is far more reliable a practise that going out and always, always finding unrelated to breed together. Unrelated and likely unlike each other too. We have a limited gene pool in Dorpers here in Canada and one of the reasons that one vet (that created Boss Man) got out of this breed was his frustration at always having to bring in new lines...gets expensive plus difficult and you are heading to a place where the entire population in the world runs out as being a source for new blood.
This is domestic livestock, registered in a limited gene pool that needs to conform to a Breed Standard.
https://en.wikipedia.org/wiki/Outbreeding_depression
So now to avoid outcrossing depression. You breed out too often and there are negatives like negatives to inbreeding depression. Conformity is important when breeding domestic livestock that has a breed Standard to adhere to...we are breeding a breed to produce PUREBREDS and we want the Dorpers to conform to a Breed Standard (set outline of traits as our objective).
Like to like begets more LIKE but also can act exactly like close inbreeding. Mother Nature does not care where the same traits come from and I abhor the use of the term "inbreeding depression"...because you can get the same negatives from breeding two distant animals together that are NOT related but have the same characteristics or traits (as often listed in the BREED STANDARDS!). So the more your animals conform identically to the Breed Standard...and with a closed registered gene pool (only allowed to choose to breed from other registered members), that limits the diversity even more so.
Closed purebred registered group = limited breeding gene pool.
Adherence to a Breed Standard = more animals that are the same.
Same to Same repeatedly over & over = inbreeding depression just like they were heavily inbred or related to each other even when they are not related!
Hybrid vigour is Nature's reward for choosing to keep healthy diversity in your gene pool going on.
Humans choose to keep closed registries on animals which lowers diversity and breeding choices. I am blessed I can upgrade the Dorpers...more options there!
And humans choose to breed animals to fit a Breed Standard (peas in a pod).
When perusing Eldad's ancestors, DEL'MAR is his origin which is also in my foundation ewes. Granted, there ARE some highly inbred animals in these lines...ah but the majority of these used over and over again animals ARE Type 5 Dorpers! The grading system is rated to a maximum of 5 points for conformation, size, fat, colour, and cover. A label like Type 5 Dorper is the top notch mark in this grading system.
DEL'MAR had many of their Dorpers graded by South African qualified inspectors. There are ewes AND rams there (two rams in his pedigree, 2nd from the top of the list and fourth from the top of the rams) that are listed as Type 5 and stated as being "Superior Herd Sire" in conformation, size, fat, colour, and cover. Both rams and ewes are graded and Eldad's pedigree looks like a who's who in Del'Mar's top flock graded Dorpers along with other lines of Type 5 Dorpers.
If they are inbred, it is on top end proven Dorpers.
The TYPING of DORPER SHEEP is done by using the information in the STANDARD OF EXCELLENCE
The Standard of Excellence is the Breed Standard.
http://www.canadiandorper.org/typing_of_dorpers
The Canadian Dorper Sheep Association CDSA has in the past, arranged for qualified Dorper inspectors to come from South Africa to Canada to type CDSA members flocks.
Likely I won't inbreed like some have...but a back cross now and again...can't knock that breeding strategy as you can see Type 5's are replicating MORE Type 5's!!

Seen this one. Wrong breed though. Dorpers with white heads are not the same as Dorpers with Black-heads (what I have). Two different strains according to the Canadian registry.
CANADIAN LIVESTOCK RECORDS CORPORATION
CANADIAN SHEEP BREEDERS ASSOCIATION
RULES OF ELIGIBILITY
A. Dorpers are of two strains, namely Dorpers and White Dorpers. Dorpers and White Dorpers shall be clearly identified and maintained as two separate strains of Dorpers. The Dorper registry shall restrict the recognition of matings between the two strains in accordance with their respective rules of eligibility herein set out.
C. Mating of Fullblood Dorpers and White Dorpers will nullify the Fullblood and purebred registrations of any progeny. The progeny of such mating may be registered in the CSBA grading-up program as 50% Dorper-White Dorper. Grading-up by strain may proceed towards a purebred equivalent level.
Some things apply to both strains; like they won't go to fat on what I feed them, but the whites have like maybe just under 20 breeders across all of Canada and the Black-headed Dorpers (referred to as just DORPERS) have that many just in each province or so.
Many persons have both White Dorpers and Black-headed Dorpers.
Back to me and the expensive racks of lamb. Laugh my butt off...same grocery store, pretty likely the SAME lamb...now cut into chops (suspicious long boned, clean ended bone on the chops--like you do for racks of lamb) ... so nobody wanted the racks of lamb in the shrink wrapped plastic...so the butchers must have cut them to chops. Around about $13.50 to $14 a kg. After the last fiasco...someone ELSE can convert the price per kg to pounds...I missed the dollar conversion then kg to pounds and not caught up on being burnt out and plain tired.
Yesterday evening, I cleared out the ram barn, Rick moved it to next pasture and we set up the corrals and whatnot's at the new location...all in preparation for Eldad's arrival. Son just called, got my livestock manifestation and bill of sale (in case the owners have not drafted either up...moving). So past paying for the crate to haul him in (do that tonight), we are as ready as able.
Bring on the ram lamb!
