We are doing the meds and set up at our house so not paying feed and board. Its going to cost me $55-60 per cow for Multimin, hormones and CIDRs. $100 per cow for the embryologist to put the egg in. I would consider the feed to be minimum of $50 per pair per month if I was paying board for 3-4 months, likely. I would not move them until 60 days after you put the embryo in but some will do 90 day pregnancy before they are willing to move them.
My cost (at home): $155-160 per cow (we feed and provide labor)
Boarded cost: Minimum of $355-360 (they feed and provide labor)
I would think that depending on the type/quality of the feed and how they charge labor it could be $100 a month or more.
