COG is typically too high.
Typically age limits fat cull cow price low. It can be profitable if cows can be bought cheap and grained heavy for 6-10 weeks to bump up a grade, but often dairy culls are 3-4 yrs old and thus too old to hit select. We have grained a few 24 month old cull cows and have had them go choice and a few hit prime, but they were young enough to not get kicked of the grades due age. Since most are culled late in lactation they get too old and you are stuck with cutters; spend too long fattening a 24 month old and you end up with cutters.
Assuming 1400# cull, for every 10/cwt under cull price you are looking an a difference of $140. Dairy culls will consume 3%/day or approx 40#/day of feed, if your ration is $170/ton (you will need high energy to gain weight) that is $3.40/day for feed so simple math is 140/3.4=41, in other words in 41 days you feed bill will be the same as the increase in value. Take out trucking and yardage and you will have to buy them 20-30/cwt back from cutter fat price and that is difficult in today's market. If there is an excess of culls on the market it can be done, but there is a lot of risk. Taking a cull cow from TMR and pushing them on grain will take a couple weeks to transition and is high risk for bloat.
