[QUOTE="cow pollinater, post: 1400926, member: 14661"] Not only that but there will be considerable differences between collections with each bull. My hunch is they collect data when it looks best and then stop collecting data. :nod: I have used hundreds of bulls in the hundreds and thousands of units range on each bull and have flagged different collections on the same bull in the computer myself when I enter breedings and have seen up to 10% variation on the same bull but different collections. VERY few bulls last long enough or have enough demand that a true improvement can be recognized and the best of those are about a 3% improvement over average. [/QUOTE]
