I think you should do more home work on the cull value of a dairy cow.
so over the last 2 years a good producing dairy cow was worth about $2200....this year that same cow is worth on ave $1750 a decline of about 20%.
Your so called savoir in the beef cull price is just ridiculous as current meat schedule for a cull cow ave about $4.35 and given diary cows genetics are made to produce milk and not meat your ave dairy cow is not that heavy once dressed out and on the hook....... so would weigh about 180kg on the hook.
So last years milking cow that was valued at $2200 on the books would be worth about $780 on the hook..............
I run over 100 head of cattle so are well aware of the schedules.
here's a link to this weeks north island meat schedules....prices are lower in the south island.
The relevant section for cows is listed under COW

probably buy more NZR shares with the money.
might even buy some more beefies as I am a little under stocked at the moment.
