I'm very shortly hoping to introduce AI to our cattle breeding. I'm doing a course in a couple of weeks. My plan was to then synch all our cattle and attempt to AI. I was recently speaking to someone who has a large seedstock operation and uses a lot of AI. They made the observation that in their experience they see a big difference in the quality of calf between natural heat and a synched heat. Their experience is that calves from a synched heat were of poorer quality than those from a natural heat. His theory being that with a natural heat the uteris is in a better initial state for growing an embryo. This is obviously just anecdotal but i'm wondering if others have similar observations or if there is any real research on this?
