interesting read on line breeding - Page 2

Vk, I'm not talking about looks for the show ring. This was in the early sixties in the us, collie breeders lined up with litters to pts because of a disease caused by a recessive gene with 100 percent penetrance. It has absolutely nothing to do with the shape of the dogs' head. It is in other breeds such as the Australian shepherd, border collie, Lancashire herder...not just collies. Has nothing to do with ethics.

There is no one who knows what they are doing with inbreeding or linebreeding.  Many of the traits that are being loaded into the gun are not known or knowable until the damage has long been done .. sometimes not until the next generation or two or even further out as the bad genes accumulate in the bloodline.  You can't cull on gene combinations that operate with incomplete penetrance or multiple alleles because the damage can be hidden by epigenetic or environmental switching of genes until three generations down the line you hit on a mating combination that pushes all the right buttons and then there is hell to pay.  There are a whole set of "tells" which indicate that inbreeding has gone too far but many, many breeders ignore the inconvenient truths until too late.  And for what??  Nothing but ego and some fleeting and passing fad or concept of perfection that never was???  Don't pretend that at 8-12 weeks the devil has been paid for inbreeding.  If you are willing to raise entire litters to adulthood and see what the inbreeding can produce then have at it but the health and mental problems which inbreeding can cause is more likely evident at 8 years than 8 weeks.  The trouble comes slower but it comes with linebreeding if the deck is not reshuffled. 

 

so how many foundation animals caused the bajillion gsd puppies ever born to the current day?

An interesting example of using one animal too much .. time will tell what using this one Holstein Bull to breed 500,000 offspring will cost the Holstein breed of cattle but there will be a price to pay.  Most dairy cattle never live past 6 years of age as most cows are culled and slaughtered at 6-8 years of age if they are lucky and live that long.  Inbreeding reduces lifespan and the effective breeding lifespan .. the more inbred the animal the shorter the lifespan  .. sound familiar in the GSD??  In the GSD we can't eat our mistakes.  The loss of genetic diversity to inbreeding also reduces the overall health of the breed and leads to an ineffective immune system or immune system or endocrine system malfunction and diseases.  Do we have problems with this in the GSD??

is that meant to be a bad example???

 

you have only theorised a problem that does not exist.

 

the morgan horse a proud american breed, supposedly only 1 sire to start the breed.

 

the murray grey, top performing australian beef cattle breed, started from 1 cow, now there are thousands of commercial studs based on that 1 cow.;

 

your point is again, clueless people should not breed animals?

 

here is a product of inbreeding, a superior animal in all measures for it's purpose

 

another result of inbreeding, superior type for it's purpose, all naturaal no steriods or growth hormones;

 

Mmmm..cow..

they are examples of the breed, the original cow that started the murray grey is long dead, the image is a bull to show you what the breed looks like.

the second bull is another breed the belgian blue that is massively line bred, but still all natural methods (ie not a lab experiment) that resulted in the breed.

 

the morgan allegedly from one stallion, this one;

 

 

 

the bully grey, one of the finest hog dogs on the planet

"Finally after 30 years of line breeding I believe I have finally produced one of the most versatile working dogs available today."

i have seen this dog, beware imitations;

 

makim dog, another heavily line bred awesome aussie pig dog;

 

 

 

 

 

The current science and genetic data indicates that almost all dog breeds alive today were selected from the grey wolf population before mankind killed off a large part of the grey wolf population worldwide.  The process of selection and inbreeding to form the dog breeds resulted in animals based on the grey wolf that are all less fit for survival and long term fitness than the original grey wolf population.  Every dog breed including the GSD are less fit to survive without human intervention than the Grey Wolf.  Put another way, if humans disappeared and left all of the dog breeds we have today to survive without human help and we came back in 10,000 years what we would find is a lot more grey wolves and none of our dog breeds would be found.  Inbreeding on artificially created strains of an animal species does not make it more fit or more healthy.  Inbreeding and the creation of dog breeds may create a few individuals more pleasing or with a few talents or traits more pleasing to a few humans but the process always results in less fit animals as compared to the original population from which the dog breed or animal population was derived.  Feral swine are an example of what happens when a domesticated breed is allowed to return to the wild as the survivors always return to their wild body type and instincts within a few generations.

has the apocalypse just happened, why is that even relavant?
