[QUOTE="Idaman, post: 805107, member: 14119"] Our decision to flush all the available cows was made this way. To wait and flush just the best one would take years and the danger of losing some with this small number would have been too great. Each one is absolutely unreplacable. We have in the somwhat random way of flushing them all have found out some very interesting, at least to us, things. 1. By flushing them all we have quickly found out which ones were the most consistently fertile. One consistently produces 18 embryos others 12 down to one at 2. The highest producers are the first to come in heat after the Lute and show the best standing heats. 2. When we flush in sync. with the recips. and implant fresh the ones that produce the most embryos will have the most implanted. Again a range of from 0-12. 3. Of the implanted embryos which donor will produce the most pregnancies. On a percentage basis that ranges from a low of 66% to a high of 94%. Now we have learned who is the most fertile, settles to AI the best, produces the most and best embryos, and whose embryos are the most likely to attach and make a pregnancy. Done in this random manner the best will rise to the top on a natural elimination basis. We will do the low performers for several flushes that have had health problems and then flush their daughters to see if the ones with health problems were affected by those problems. This is against all conventional wisdom but so what we are developing a uniquely tested herd. They survived the horrible winter where they came from, adjusted for the haul, and vastly different climate, were tested and cleared for ET(each and every one) and are now going through the ET success rate test. Plus they were all born after their dams were at least 11 years of age. What whole herd has been tested in this way? [/QUOTE]
