Roberta,

Line breeding concentrates the genes.  It does not dilute them.  When you 
line breed you are using similar familial genes.  Thus possibly doubling up 
on the same trait.

Carol,

Thank you for answering my question.  I can understand the feelings on 
inbreeding but linebreeding is going back to related ancestors.  I would not 
think there are enough Fjords to totally outcross everytime.
Linebreeding is also a valuable tool in finding out what the strengths and 
weaknesses may be.  Since it concentrates the genes some.  It is not 
something that can be used without studying pedigrees and knowing the 
lineage.


You can get the same  problems by outcrossing.   I would not think the gene 
pool in this breed is large enough to have the diversity you would need to 
avoid genetic problems.


As far as dogs go.  Putting puppies down is not a viable option.  We see 
more genetic defects from those who do not linebreed and do not understand 
the pedigrees.  The key is knowing what is behind your dog.  Sometimes the 
knowing can be the most valuable tool.  By outcrossing every time you do not 
know what your dog carries.

Hello from Carol Rivoire at Beaver Dam Farm in Nova Scotia ---

Lisa Wiley asked me this question . . . .

Carole,

Could you please explain the following statement?  Why would line breeding
or inbreeding cause these problems anymore than outcross breeding?  If the
problem is in a line it is there doesn't matter how you use it.



The worth of a Fjordhorse depends on many many things, the first one being
his LINEAGE.  --  If he or she has a screwed up pedigree --- linebred,
inbred for instance --then in my opinion, he has very litle value because
you don't know what lurks in his genes that may cause serious trouble in 
his

and your future.  --  He may look OK, act OK now, but may go blind at ten
years of age --  Or something else equally devestating.

Well, I'll try in simplistic, layman's terms.  There must be someone else on 
the list who could explain scientifically.


Every animal and human has  weak and strong characteristics in his genetic 
makeup.  If an animal is inbred meaning he's  the result of a stallion 
breeding his mother or daughter, then the weak genes get multiplied along 
with the good genes, and this multiplication can be disasterous to the 
physical and mental health, soundness, and longevity of the resulting 
offspring.  --  Whew!  That's as scientific as I get!  --


The NFHR does not allow inbred horses to be registered.  This includes 
father to daughter matings, mother to son matings, full sibling matings, and 
half brother to half sister matings.


It's a recognized fact in breeding all animals, and humans, that breeding 
closely related individuals causes mental and physical problems.  --  I know 
it's done frequently in dog breeding, and I don't agree with it at all, but 
at least with a litter of puppies, the dog breeder may be able to  destroy 
the malformed ones.  --  At least those that are recognizable at birth as 
not correct.  --  With the long gestation term of horses, and the fact that 
only one foal is born at a time, as well as the cost of breeding horses, the 
results can be much more significant.
