[QUOTE="TwoByrdsMG, post: 1769955, member: 37975"] Talked with the breeder over the phone a couple times since receiving the results. Pulled hair again on the cow and having her retested (at Neogen since they have DNA on the sire to verify). We both suspect that the lab (Neogen) mixed up the samples (which means they have screwed up or lost half the samples I sent to them). Only sent one sample this time to reduce the probability of another lab mix-up. Found out the hard way that I have no authority on anything I send them since association is sending me the paperwork for the samples. Even more curious... I sent in a request for testing on a donor at the same time and that donor's results came back the same day in sequence with my results (as PAF). I requested that the donor have her DNA verified to her original DNA but I'm not authorized to do it unless I get permission from the owner. Said owner had no issue sending me the PAF results but ignored me when I asked for DNA re-verification. This gives me very little faith on ANY results from that lab... but at least a few of the ones I sent were sire verified. Bought her from a breeder in Kansas that is actually dispersing this year (family operation it sounded like the father is dispersing but potentially son is keeping the herd name?). He said (though I have no way to verify this) that those heifers were at his house with no white bull within 5 miles. Penned up and 7 out of 8 took to AI so he did not run a cleanup bull and kept the heifers there to keep the grass down around the house. He gave me the AI date on the dam and said that it was the second cycle that she was bred to Resource. She calved at 286 days post AI date. He used one other AI bull on the group of heifers and that sire was not verified either. Sent hair for the first "lost sample" and another one for the Charolais cleanup bull to UC Davis. Samples arrived at UC Davis and Neogen on the same day but I'm betting that UC Davis will have results out first. If this gets to be any more of a headache I may just send them all the the sale and get on with my life. [/QUOTE]
