Thank You for responding, I talked with my AI Tech again and he said it works exactly like you said. I do have another question for you, you said you had an increase in heifers than bull calves. How is that? That would be the ideal thing for me, I am building my reg. herd so I would be keeping all the good ones for several years, I didn't know there was a way that you could raise your chances of one sex over the other. Thanks again for talking with me.
