[QUOTE="kfacres, post: 910796, member: 13824"] In my experience, it depends more on the age of the sire-- more so than the AI or natural service. At our place, I experience about 75-80% females from a young first time yearling sire, and about the same %, but opposite, from a 6 year old sire in terms of male offspring. I think with AI- the same holds true... As a result, I try to collect my sires at least twice- once early in life (to get females) and once later- for those males. I have found this to hold up more times than not. It's exactly opposite- of what I want though-- as when I use a sire I want to sell the offspring from the first couple of crops- but by the time he reaches his prime and is ready to move on: I'm ready to keep daughters from him- however at that point in time- his daughter production- drops off hugely.
