Well its funny you asked, lately we've been thinkin of flushing our good HW x Chill Factor cow and have even talked to Donor Solutions. Personnally I can't justify paying 5oo to 1500 for embryos and havin a 1 in 3 average. So we'll flush our own and hope for the best. Also we know what works on her and have the chance to greatly multiply the good ones. Plus now it lets us keep trying to find other matings that may be even better. Were not flushing to sell embryos, but I think a guy could sell some if you kept the price around 150 per egg. Maybe more guys would try ET. Also there are few certified embryologist in our area, its hard to get some one to drive 50 miles to inplant 2 eggs. It used to be that way with AI, but now every body does it even me, lol. I only do my own, not near enough experience to do other guys cows.
