Tragedy in Siberia!! Help Get Milk Production Back!!!

Hey fellow permits. I operate a small dairy in Siberia, Russia. We are not allowed to actually homestead land, so all our cows are free range. A few days ago they did not come home, we went out to look for them and could not find them. Long story short they were gone for 2.5 days and missed 5 millings (two mornings, two evenings, and a morning). We have six milkers. Two seemed to be ok, milked them out and they have kept giving, less but not tragic, but four of our good milkers are down to a little over a cup each. It's an unprecedented tragedy for us, might be the end of our operation, in as much as milk is our main cash crop.

So the question is this, what can be done, if anything, to restore milk production. I am milking them 3 times per day now, keeping them in the barnyard, bringing fresh grass and hay for them, mixing oats and fennel into a slop for them. Anything else I should, could be doing???

Any advice would be really appreciated!!!

Make sure they are eating as much as they want, not allowing them to free range will probably suppress milk production, perhaps take them for an hour walk to eat twice a day, especially a while before the sun goes down around 4-8 o clock is when the grass has the most sugar. Get them in with a bull as soon as they come into heat so you can milk again sooner next year unless of course they are already bred. How old are your cows? Young cows never make nearly the milk that older cows do and may dry up sooner. They could have been through some kind of trauma such as a predator chasing them.

Thanks Emil for the reply. We ended up keeping up pasturing, thanks for that tip. We started giving them an oat and fennel slop twice a day and milked 3 times a day for three days and then back to the normal 2 times a day. Got all of the cows back up to about 80% where they were before they got lost, except the youngest cow who is up to about 50%. The two oldest cows are almost 100%! Fennel and oats.
