serious inbreeding question

[TFX]

let's be realistic you can't keep doing it forever.

Tell that to my friend who has the closed herd of Hereford cattle that has not had an outcross for 131 years now. Jack is right, you CAN do it forever, IF you know what you are doing. The old Irish lines were so tightly bred that the quality was actually diminished when crossed. Rather than consider the probability of inbreeding like a coefficient, my friend's cattle were tested at a university genetics laboratory and found to be 94% identical genetically, with only 6% variation. Talk about knowing what you are going to get every time! So yeah, it can be done, it has been done for centuries, and is being done now.

Wow. I remember you had mentioned this years ago.

What are the traits this man's cattle are best known for and what breeding patterns (if any) has he found to be his favorite or more consistent than the other?
