Which works better in concentrated feed, probiotics or compound enzymes?

Everyone, let me ask: I want to produce concentrated feed, and I want to add probiotics or compound enzymes to the feed. Which is better? Probiotics cost 30 per ton of concentrated feed, and compound enzymes cost 50 yuan.
I hope everyone can give me some guidance!
---------------------
If medicated feed additives are added to the concentrated feed, it is recommended to add compound enzymes.

Thanks
Thanks everyone
---------------------
If your concentrated feed does not contain medicated additives, probiotics can be added as a substitute.
---------------------
There are antibiotic drugs, nitrofurans
...
---------------------
Compound enzymes, I think. Probiotics seem to be rarely added.
---------------------
Are there still any premixes now that do not contain medicated additives?
---------------------
Compound enzymes..................
---------------------
Maybe compound enzymes are better.
