I have never paplpated a cow before and recieved a blood test results back saying that she was preg but to retest because she wasnt quite 90 days post. at the time I didnt think it would matter to me but now I would like to know. she should be 130 days preg, what are my chances of doing a palpation never have done one, I have a general idea of the anatomy but like i said never have done one.
