What must you anticipate with this road sign?

You got it right. This traffic sign in Germany warns drivers of possible farm livestock on the roadway, such as cows or sheep. Because of this, it is also likely that the road could be soiled by dirt or manure carried by the animals. You must anticipate both situations: livestock on the road and a potentially dirty or slippery surface. The sign does not refer to wild animals crossing—that would be a different sign. Remember: when you see this sign, reduce your speed and drive carefully, as animals or dirty road conditions may suddenly appear.
