I've been using Kintracks for about twelve years. It's good for a lot of things other than making pedigrees. I find the most useful function to be the level of inbreeding button. I can select a pair and then see how inbred the offspring will be. We're on an island here and getting new blood is quite difficult since to ship in bunnies, I have to have someone on another island go pick them up from the inspection desk and shift them to an inter-island carrier. I can't get direct shipments to my island. So, having the 'coefficient of inbreeding' button lets me breed with a very small gene pool and not end up with inbred rabbits.
I did like the old Kintracks over the newer 'Animal Breeder' software that is now the new Kintracks, but part of that is probably just because I'm used to the older software. I'll look at the Global Pedigree site, though, that may be a good source for getting more breeding stock?
