The short answer is "no". Nobody says that in English. Except of course that I am going to start saying it just because it sounds kind of cool...

Answer updated; the phrase is a literal translation of the Russian, seen in translations of Russian texts, and in English texts written by Russians. Maybe it will take root in its new home...

In Poland we are saying: so that the wolf is full and the sheep is whole

It was my mistake when I gave equivalents. It would be better just to ask about existence of this phrase. Your point is very interesting. Still, you think that this phrase exists in the English-speaking world. And this is not just a translation from Russian, but already accustomed expression. Though, we can't say so judging by all the answers below.

If it was originally Russian then there will not be an equivalent, The same applies with any translation from one language to another. you say not equivalents in your first sentence, but then say "English equivalents sound like 'hold with hare and run with the hounds' ". My suggestion is the correct version of "hold with the hare and run with the hounds. The other translations are totally different idioms. And yes such an expression as "Wolves are fed and sheep are safe" does exist In English. We got it from Leo Tolstoy's "war and peace" “But our idea is that the wolves should be fed and the sheep kept safe. ”
