Ask anyone who has a dog with cherry eye or hip dysplasia about how well that works out. This has to do with recessive genes being paired up so that a problematic gene is no longer masked by its healthy counterpart.
Line breeding can be done responsibility to fix a specific genetic trait in a the population you are breeding. However, it has to be done very carefully. You must be certain that the original parents are not carrying undesirable recessive genes or you will end up with defective traits also being fixed in the line along with the trait(s) you wanted.
This generally requires breeding both parents first with partners that are known to carry defective recessive genes to see if any of the recessive traits appear in the off spring or doing extensive genetic testing on the proposed parents to look for known bad genes.
Get with your neighbors and swap stock. Keep records on who's stock you swapped with and cross them off the list. It's worth driving an hour or two to keep your herd healthy and not running up the vet bills.
