- To those interested in inbreeding and thus inbreeding coefficients, do you rely on the AAA calculator, use a computer program or calculate by hand? I've been looking at AAA coefficients and they appear to be calculated based on 3 or 4 generations. Have run some with Kintracks, but at least one result is clearly wrong. That wrong result is especially disappointing after entering data for several hours.
Mike I use the Kintracks program out of mild interest, I believe there are less mistakes with it now than there were prior to some changes they made as a result of a discussion (on 5BarX I think) Maybe look up that thread as the owner of Kintracks posted on there.I don't know how to work it out longhand and I'm too lazy to learn so I use Kintracks but as I say it's out of mild interest - not as a means to make breeding choices. | |

| How many generations does it calculate? | |

| I probably have a bug in my computer, but when I try to use KinTracks my computer goes right to my Peachtree accounting software. What does anybody else use to compute inbreeding coefficients? |

| AAA must use about 5 generations...Kent figured 1707 at 53% for me with either a 10, or 15 generation analysis...AAA computes her at 47%...those ancestors farther back than 5 generations won`t contribute very much to IBC; still interesting.... | |

| Back on advantage, dr. Switzer was using something called ped parser from someplace in Australia. It wasnt to hard to use, and would do as many generations as you wanted. I just don't know how to get it anymore-- it used to be available online for download, but I couldn't find it recently.

Dwight, I have an older version of compuped: http://www.compuped.com/It will calcualte IBC to 30 generations and give other interesting information. Lots of capacity. | |
