I have had simmitals for a few years. First time bred they were in a pasture with a bull. Now they are bred Artificially Inseminated. Cost for 3 was a bit over $200 which included work on last years calves. The steps to A I were great. I know when they will calf almost to the day. But I have also heard, that the sex of the calf can determine the length of gestation. klhnew cow people said:
