I have often wondered how accurate the pedigrees on cattle really are. I think there are more mistakes that a lot of people realize. Over the last year or so I have found mistakes in purebred breeders catalogs a total of three times. Each time the discrepancy was discovered when the Genestar data was included. By looking at the Genestar results it was evident that the bull listed as the sire could not be correct. Each time I contacted Bovigen and the producer. bovigen stood by their results and the lot in question was removed from the sale by the producer. I am not saying these are intentional mistakes, but just mistakes. Since I found three in such a short period of time and it is impossible to spot mistakes based upon the Genestar data in 99% of the animals, I wonder how many mistakes are not caught. Just got me to scratching my head on the issue.
