Bulls can see some color but bulls are partially color blind.
Contrary to popular belief the color red does not make bulls angry.
In fact, bulls are partially color blind compared to healthy humans, so that they cannot see red.

Bulls are strong, muscular, mature male cows.
Male cows are typically slaughtered at a young age in agricultural production, if not kept for breeding purposes.

Bulls do go moo just like other cows do.
A bull in reality is just a different type of cow and does moo like the other cows do.
However a bulls moo may be a different tone sometimes than a regular cows moo.
So you should hear a moo but it might sound just a little bit different than a regular cows moo.
You can usually discern the moos between a cow and a bull.
You just have to listen to a regular cow moo and then listen to the bulls moo and then you can easily tell the difference.
