Pig manure is yellow in color. What does this indicate nutritionally?

The pig's manure is yellow, but it is not diarrhea. These pigs eat the same kind of feed. I think it should be a feed problem. Is something lacking, or is something in excess? Please, seniors, give some advice. I also posted the same thread yesterday, but I could not find it today, so I posted it again.

Is there any change in body temperature?

How is the feed intake? ⟧7⟧Everything is normal, thank you all

Is the anus swollen and red?

Feeding too much, not digested well! Reduce the amount of feed.

With excess copper sulfate, the manure would be blacker! You are wrong!

As long as the pig's spirits are good, do not worry about it,

Also, you did not say what kind of pig it is.
