Starting new bloodline ?s and inbreed coefficient ?s

Great post behavin!... the scientific stuff frys my brain everytime LOL
Thanks mate.

 

Thanks for posting this.

 

Good reading.

 

im thinking that when starting your own family of dogs you have to stick with it cause if cull everything you will forever start over and not accomplish anything so choose wisely where you start and thats how I believe the old timers took not so great dogs eli bullyson snooty and all those names and made a great family dedication to what the started

 

Culling helps selecting what animal you want to keep and preserve the traits within the gene pool you have. This should only be done by folks that keep the whole litter till they mature. Dog men in the fast lane don't need to breed dogs. Their efforts are better used finding a prospect and putting it through a keep. If it don't work out sell it and more on. Having a yard full of hounds that might win is a expensive deal. Those dollars are better put on the dog!

dogmen need breeders but not the other way round. Culling is for them but dogmen don't need to. The hound that will work through a game test and match will either live/die/re-matched /be sold.

 

Thanks HammerHead!!! You summed it up best! Tired of people saying that good dogs aren't available to be bought because dog men keep em all for theirselves! Dog men gotta get dogs from somewhere!!! But I myself as a breeder do feel like I need the dog men, because without them I wouldn't know where I stand among other breeders in production of dogs.

 

Inbreeding is as genetically dangerous to strains and sub strains as outcrossing is... both are also fire when done right.....

Canis Lupis - Species (wolf)
Bulldog or Bull and Terrier - sub species
Colby, Old Family/red- strain
All other APBTs - sub strains

Speaking genetically this is as simple as it is. DNA and mtDna go back thousands of years.. All dogs on the DNA scale are Canis Lupis.. So they are mutations of Canis lupis but are not their own species, they are of the wolf. You can breed tight tight tight and have the best or worse in the world you can use an outcross and have a dime or a plug nickle.. culling from breeding program is a necessity; Not everyone should be breeder.

Good dogs are where you find them.. ITs important to have genuine dogs with genuine peds otherwise you dont know what your dealing with genetically and what traits the dog has. In a 7 gen ped there are 256 ancestors each member has dna offering to the individual from 256 ancestors so the individual is getting dna and mtDna from 20,000+ ancestors..

How long does it take to build a solid strain? 10 generations of correct breeding.. Check the old school Colby, Lightner and Corvino .. only one is a Strain, Sub Strain and Sub Species... .. Boudreaux is a sub strain of corvino.. so on and so on.. Dog men can be remembered for being a great handler or breeder, you can't be both there are only a hand full ever. You got a 10 gen ped that is genuine to the dog you have a dna map and blue print to the dog.. Inbreeding just to stack peds is not the way to go there is a world of slop out there just from such practices, and outcrossing just cause you've inbred your dogs for a bit is not the way to go either... For any of the APBT sub strains they just look for their outcross by refreshing the dna code from the strain it came from. DNA goes back 1000s of years, remember. SO.. This is why guys like Heinzl, Tudors, and such went back to the old colby dogs even Corvino and Lightner crossed them in.. why.??.. For Paddy ... Most of what we have if not is down from Paddy, Gas house, and Pilot.... So for boudreaux, the closest would be, .. Clouse.. and for Jeep .. colby or old boudreaux stock that is bred up off his bottomside (because there are a few Jeep trophy dogs out there that have no where to go so they believe) In this you are not outcrossing.. you are refreshing.. Jeep and Redboy are both Colby and Old family.. so it worked great for a long time.. but now its all wound up every angle it can go.. basically they are OFRN dogs I call em SFRN southern family rednosed LOL... it needs a dna refresher of a precurser not another strain of inbred dogs.
Any horse people in here? .... , this is why derby and track race horse breeders take thoroughbred back to Arabians.. for that PRIMAL FIRE and a re fresher of lost or dormant traits.

Very few people have the time and patience to build a legacy in a strain or sub strain of dogs.. 10 gen to build a solid sub strain .. to be a strain have to be legacy building block in the majority of the stock of other various sub strains.. Each indidividual in a ped has the Dna mtdna code and donation of material for 256 ancestors, so again you have 20,000+ ancestors your individual is build from. Keep this in mind and make sure you have genuine stock if not gotta be honest with yourself and the dog and leave it blank behind him because you don't know what he/she is throwing. .. Until you've bred them long enough to know what they throw every which way they are bred.

 

Somebody gots a long way to go... Is these your words? 10 gens is laughable

 

Here is an inbreeding calculator I found works great.
Inbreeding calculator

 

I have seen lessened mental capacity in dogs inbred over and over in a friends yard.
A stud dog with an inbreeding coefficient of 35% threw real tight pups (in a line-breeding, as well as an out-crossing). But, not to tight.

My breedings tend to be 17-25%. I have seen well functioning game dogs (just the ped and photo) that were in the 70% range. This breed is bred tighter than most.

I believe inbreeding coefficients are important, but the health of the dog is more so (obviously). If the stock is super, the % can go up with little defects.

Yes, the good and the bad will come up if you inbreed. All 3 breeding styles have their place (inbreeding, line-breeding, out-crossing).
