In case you haven't heard, we have almost no interest in pedigrees and bloodlines as a means of determining genetic quality. When folks talk about bloodlines, they're usually using them a method of adding value to their livestock based on the attributes of their great-great-grandparents. Unfortunately, genetics don't work that way. After a couple generations, a bloodline begins to have very little in common with its ancestors (without some method of genetic culling).

So, you may be wondering why people who don't like registration papers are talking about breeding lines. That's because we're using them for a different purpose than most people use bloodlines.

Although each parent's genetics are somewhat randomized when a sperm and egg combine, a brother and sister still have many similar attributes due to their shared parentage. This means that if two goats that are closely related are bred (inbreeding), their kids have a much higher probability of containing traits that would otherwise have remained hidden. In some rare instances, this can result in genetic "super heroes" - but not usually.

Inbreeding often creates genetic defects such as missing limbs, organ failure, and infertility. We don't want any part of that! So, that's why we have four genetically distinct breeding lines to diversify our stock while still maintaining the genetic quality: the Main Post Oak Line, the Post Oak Juan Line, the Post Oak Carlos Line, and the Post Oak Paco Line.

By constantly randomizing the bucks from each line, we refresh the available genetics without endangering the quality of the herd. In this way, we can maintain a healthy cycle of breeding while continuing to pursue our goal of producing maintenance-free livestock.
