RE: [RC] [RC] What the? breedingstock? working stock?) - heidi

Yeah, this whole working vs. breeding stock is news to me, too. I always
thought the point of breeding was to pass on traits that make a horse suited
to your purposes. Why would you want to breed anything other than a proven
performance horse? The last thing a breeder wants is to pass the bad traits
of the dam and sire onto their foals.


You're right that no conscientious breeder wants to pass on anything but good 
traits to the subsequent foals.  But proving working ability does NOT prove 
genotype!  There are many top performers who will not reproduce with any level 
of consistency at all, simply because they have very inconsistent breeding 
behind them, and just "got lucky."  Likewise, there are many top performers who 
are the result of hybridization, and whose offspring will also be "all over the 
map."   

Good breeding stock, for the most part, ARE good working stock--but they also 
have fairly consistent genetic backgrounds, so that their odds of producing 
what they are is considerably higher.  THAT is "breeding stock."  And likewise, 
the experienced breeder understands that there are times when an individual is 
apt to "outproduce" themselves, most often due to some sort of environmental 
influence that has rendered them as less than optimal for performance 
themselves.  In solid breeding programs, such individuals may well be good 
"breeding stock" even if they themselves don't work.  I'm not talking here 
about horses that have GENETIC flaws that render poor minds or poor 
conformation.  But there are those individuals that have the genotypes to pass 
on outstanding working traits, but who have such things as birth injuries, who 
are last foals of great old mares and suffered the deprivation of uterine 
insufficiency, etc.  To throw such individuals out of a breeding program would 
be utterly foolhardy.  

On the latter note, there have been some top racehorse breeders who didn't 
start with the big bucks to buy the outstanding younger individuals--so they 
researched the mare lines that produced such individuals and then bought old 
mares that had been top producers but who were literally cast-offs, and which 
they could acquire for a song.  Such mares might not produce stellar racehorses 
in the first generation, due to a less than optimal uterine environment--but 
keeping and breeding their daughters sent some of these astute breeders right 
to the top, because they had gotten their hands on the genetics that pass on 
the good working traits.

If it were as simple as breeding Champion A to Champion B to foal out Champion 
C, everybody would be a successful breeder.  But there's a lot more to it than 
that.
