Sodium bicarbonate common baking soda that you can purchase in the yellow box or 50# bag is a valuable tool to get acidotic animals back on feed and feeling good. When sheep accidentally get into excess grain you can put it out free choice and they will consume it.
It also comes in handy when starting lambs on feed after weaning when their diet changes dramatically.
Ewes after lambing can use it as well as their rumen adjusts capacity that it no longer shares with unborn lambs.
It is a product I have overlooked for years. the fact they would consume it voluntarily eluded me. Its cheap and effective.
Effective in goats as well.
