Rent the land don't buy it till you have a good herd and I would artificially inceminate for the best calves and then you know when you bred them I would sell them as bred heifers then if the price goes down you can keep them and calve them out
I agree with Cowfarmer.
We strictly breed AI. Much cheeper and way less headache. Gives you the ability to pick Bulls to improve on your cattle along with newer technology that gives the ability to use sexed semen.
Semen (sexed) $15-$25 (dairy semen)
Hormones and CIDR to Synchronize approx. $20
Not sure what a tech will cost you in your area.
